Introduction

One of the important steps in achieving the outcome of a ldquosafe and healthy workplace for allrdquois the progressive extension of the Workplace Safety and Health (WSH) Act 2006 to allworkplaces All workplaces in Singapore will be covered under the WSH Act by 2011 The

extension of the Act will cover the remaining workplaces which include wholesale and retailtrade public administration business services finance and insurance activities educationalinstitutes and fishing and agriculture sector The Act signifies a call to all stakeholdersregardless of the nature of business to play a part in creating a safe and healthy workplacefor everyone and making Singapore renowned for best practices in workplace safety andhealth

Many WSH hazards are not unique to particular industries or workplaces whether it is aconstruction worksite shipyard factory hotel healthcare facility or office For the industriesthat are already covered under the WSH Act1 the extension of Act in 2011 also sends astrong signal that while higher risk industries or work activities should remain as areas offocus no WSH hazards or risk should be neglected

This guide aims to(a) raise awareness on legal duties and liabilities from the perspective of safety and health

legislation(b) provide a better understanding on the common WSH hazards and the associated

prevention measures and(c) provide guidance on managing WSH hazards and risks through risk management and

WSH management systems

This guide is divided into four sections Section One summarises the key general duties ofemployers and employees stipulated under WSH Act 2006 Section Two provides a generaloverview of WSH (Risk Management) Regulations and the basic steps in risk managementand risk assessment Section Three lists the common safety and health hazards across allsectors and the corresponding prevention measures that can be taken Section Four

describes the WSH management programme which would ensure a systematic and effectivemanagement of safety and health

Providing and maintaining a safe and healthy workplace has numerous benefits includingreducing work injury compensation payouts decreasing absenteeism lessen the need forhiring replacement employees or replacing damaged equipment increasing productivityenhancing well-being and improving work morale among employees Use this guide to assistyou to start creating a safer and healthier workplace for all

1 Industries covered under Phase 1 mirrored those of the Factories Act ie factories construction sites shipyard

and shipbuilding and laboratories Industries covered under Phase 2 included hotels and restaurants logisticsveterinary healthcare cleaning and custodial services and water supply sewerage and waste managementsectors

Chapter 1 WSH Legislation 1 Overview of the WSH Act

On 1 March 2006 the Workplace Safety and Health (WSH) Act replaced the 33-year-oldFactories Act This Act signified a shift from the prescriptive legislative approach to a

performance-based regime The WSH Act emphasises on proactive WSH management byrequiring all stakeholders to identify hazards at the workplace and take reasonablypracticable measures2 to mitigate them The key features of the WSH Actbull Assigns responsibilities and liabilities to a broad range of stakeholdersbull Focuses on WSH systems and outcomes andbull Imposes higher penalties for non-compliant and risk-taking behaviour

These are based on the premise that accidents can only be prevented if all stakeholders inthe workplace take personal responsibility for achieving higher safety and health standardsSince the enactment of the Act in 2006 the coverage of workplaces has progressivelyexpanded from those covered under the Factories Act ie high-risk workplaces to includesix new sectors as below The WSH Act will be extended to all workplaces by 2011

11 Duties and Responsibilities of Stakeholders

The WSH Act assigns duties and liabilities to a wide range of stakeholders in safeguardingthe safety and health of employees and other persons who may be affected by the workbeing carried out Stakeholders refer to persons who create and have management orcontrol over WSH risks and not necessarily referring to occupiers and employers only

2 A concept that requires employers to weigh the degree of risk against the time trouble cost and physical

difficulty of taking measures to avoid the risk

Phase 1Factories Construction

Shipyard and Ship BuildingAirport Laboratories

Phase 2Hotels and RestaurantsVeterinary Healthcare

Logistics WasteManagement Landscape

Three major underlying principles of the WSH Act

1 Reducing risks at source by requiring all stakeholders to eliminate or minimisethe WSH risks they create or have control over at the workplace

2 Instilling greater industry ownership of WSH standards The focus will be shiftedfrom complying with prescriptive requirements to making employers responsiblefor developing safe work procedures suited to their particular situations in orderto achieve desired safety outcomes

3 Preventing accidents through higher penalties for poor WSH management

Stakeholders defined under the WSH Act also include principals manufacturers andsuppliers persons who erect install or maintain equipment and machinery as well asemployees At any one time a person might play different roles and hence have differentduties For instance a person can be an occupier an employer and a principal at the sametime in the same workplace

Annexes A and B provide more details on the definitions and duties of each stakeholderunder the WSH Act

Table 1 illustrates who are the different stakeholders and their duties under the WSH Actusing the example of a retail outlet

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

3 The list of statutory machinery or equipment and hazardous substances are listed in the Fifth Schedule of the

WSHA

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

Potential slip and tripsSources

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Introduction

One of the important steps in achieving the outcome of a ldquosafe and healthy workplace for allrdquois the progressive extension of the Workplace Safety and Health (WSH) Act 2006 to allworkplaces All workplaces in Singapore will be covered under the WSH Act by 2011 The

extension of the Act will cover the remaining workplaces which include wholesale and retailtrade public administration business services finance and insurance activities educationalinstitutes and fishing and agriculture sector The Act signifies a call to all stakeholdersregardless of the nature of business to play a part in creating a safe and healthy workplacefor everyone and making Singapore renowned for best practices in workplace safety andhealth

Many WSH hazards are not unique to particular industries or workplaces whether it is aconstruction worksite shipyard factory hotel healthcare facility or office For the industriesthat are already covered under the WSH Act1 the extension of Act in 2011 also sends astrong signal that while higher risk industries or work activities should remain as areas offocus no WSH hazards or risk should be neglected

This guide aims to(a) raise awareness on legal duties and liabilities from the perspective of safety and health

legislation(b) provide a better understanding on the common WSH hazards and the associated

prevention measures and(c) provide guidance on managing WSH hazards and risks through risk management and

WSH management systems

This guide is divided into four sections Section One summarises the key general duties ofemployers and employees stipulated under WSH Act 2006 Section Two provides a generaloverview of WSH (Risk Management) Regulations and the basic steps in risk managementand risk assessment Section Three lists the common safety and health hazards across allsectors and the corresponding prevention measures that can be taken Section Four

describes the WSH management programme which would ensure a systematic and effectivemanagement of safety and health

Providing and maintaining a safe and healthy workplace has numerous benefits includingreducing work injury compensation payouts decreasing absenteeism lessen the need forhiring replacement employees or replacing damaged equipment increasing productivityenhancing well-being and improving work morale among employees Use this guide to assistyou to start creating a safer and healthier workplace for all

1 Industries covered under Phase 1 mirrored those of the Factories Act ie factories construction sites shipyard

and shipbuilding and laboratories Industries covered under Phase 2 included hotels and restaurants logisticsveterinary healthcare cleaning and custodial services and water supply sewerage and waste managementsectors

Chapter 1 WSH Legislation 1 Overview of the WSH Act

On 1 March 2006 the Workplace Safety and Health (WSH) Act replaced the 33-year-oldFactories Act This Act signified a shift from the prescriptive legislative approach to a

performance-based regime The WSH Act emphasises on proactive WSH management byrequiring all stakeholders to identify hazards at the workplace and take reasonablypracticable measures2 to mitigate them The key features of the WSH Actbull Assigns responsibilities and liabilities to a broad range of stakeholdersbull Focuses on WSH systems and outcomes andbull Imposes higher penalties for non-compliant and risk-taking behaviour

These are based on the premise that accidents can only be prevented if all stakeholders inthe workplace take personal responsibility for achieving higher safety and health standardsSince the enactment of the Act in 2006 the coverage of workplaces has progressivelyexpanded from those covered under the Factories Act ie high-risk workplaces to includesix new sectors as below The WSH Act will be extended to all workplaces by 2011

11 Duties and Responsibilities of Stakeholders

The WSH Act assigns duties and liabilities to a wide range of stakeholders in safeguardingthe safety and health of employees and other persons who may be affected by the workbeing carried out Stakeholders refer to persons who create and have management orcontrol over WSH risks and not necessarily referring to occupiers and employers only

2 A concept that requires employers to weigh the degree of risk against the time trouble cost and physical

difficulty of taking measures to avoid the risk

Phase 1Factories Construction

Shipyard and Ship BuildingAirport Laboratories

Phase 2Hotels and RestaurantsVeterinary Healthcare

Logistics WasteManagement Landscape

Three major underlying principles of the WSH Act

1 Reducing risks at source by requiring all stakeholders to eliminate or minimisethe WSH risks they create or have control over at the workplace

2 Instilling greater industry ownership of WSH standards The focus will be shiftedfrom complying with prescriptive requirements to making employers responsiblefor developing safe work procedures suited to their particular situations in orderto achieve desired safety outcomes

3 Preventing accidents through higher penalties for poor WSH management

Stakeholders defined under the WSH Act also include principals manufacturers andsuppliers persons who erect install or maintain equipment and machinery as well asemployees At any one time a person might play different roles and hence have differentduties For instance a person can be an occupier an employer and a principal at the sametime in the same workplace

Annexes A and B provide more details on the definitions and duties of each stakeholderunder the WSH Act

Table 1 illustrates who are the different stakeholders and their duties under the WSH Actusing the example of a retail outlet

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

3 The list of statutory machinery or equipment and hazardous substances are listed in the Fifth Schedule of the

WSHA

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Figure 2 Hierarchy of Controls

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Introduction

One of the important steps in achieving the outcome of a ldquosafe and healthy workplace for allrdquois the progressive extension of the Workplace Safety and Health (WSH) Act 2006 to allworkplaces All workplaces in Singapore will be covered under the WSH Act by 2011 The

extension of the Act will cover the remaining workplaces which include wholesale and retailtrade public administration business services finance and insurance activities educationalinstitutes and fishing and agriculture sector The Act signifies a call to all stakeholdersregardless of the nature of business to play a part in creating a safe and healthy workplacefor everyone and making Singapore renowned for best practices in workplace safety andhealth

Many WSH hazards are not unique to particular industries or workplaces whether it is aconstruction worksite shipyard factory hotel healthcare facility or office For the industriesthat are already covered under the WSH Act1 the extension of Act in 2011 also sends astrong signal that while higher risk industries or work activities should remain as areas offocus no WSH hazards or risk should be neglected

This guide aims to(a) raise awareness on legal duties and liabilities from the perspective of safety and health

legislation(b) provide a better understanding on the common WSH hazards and the associated

prevention measures and(c) provide guidance on managing WSH hazards and risks through risk management and

WSH management systems

This guide is divided into four sections Section One summarises the key general duties ofemployers and employees stipulated under WSH Act 2006 Section Two provides a generaloverview of WSH (Risk Management) Regulations and the basic steps in risk managementand risk assessment Section Three lists the common safety and health hazards across allsectors and the corresponding prevention measures that can be taken Section Four

describes the WSH management programme which would ensure a systematic and effectivemanagement of safety and health

Providing and maintaining a safe and healthy workplace has numerous benefits includingreducing work injury compensation payouts decreasing absenteeism lessen the need forhiring replacement employees or replacing damaged equipment increasing productivityenhancing well-being and improving work morale among employees Use this guide to assistyou to start creating a safer and healthier workplace for all

1 Industries covered under Phase 1 mirrored those of the Factories Act ie factories construction sites shipyard

and shipbuilding and laboratories Industries covered under Phase 2 included hotels and restaurants logisticsveterinary healthcare cleaning and custodial services and water supply sewerage and waste managementsectors

Chapter 1 WSH Legislation 1 Overview of the WSH Act

On 1 March 2006 the Workplace Safety and Health (WSH) Act replaced the 33-year-oldFactories Act This Act signified a shift from the prescriptive legislative approach to a

performance-based regime The WSH Act emphasises on proactive WSH management byrequiring all stakeholders to identify hazards at the workplace and take reasonablypracticable measures2 to mitigate them The key features of the WSH Actbull Assigns responsibilities and liabilities to a broad range of stakeholdersbull Focuses on WSH systems and outcomes andbull Imposes higher penalties for non-compliant and risk-taking behaviour

These are based on the premise that accidents can only be prevented if all stakeholders inthe workplace take personal responsibility for achieving higher safety and health standardsSince the enactment of the Act in 2006 the coverage of workplaces has progressivelyexpanded from those covered under the Factories Act ie high-risk workplaces to includesix new sectors as below The WSH Act will be extended to all workplaces by 2011

11 Duties and Responsibilities of Stakeholders

The WSH Act assigns duties and liabilities to a wide range of stakeholders in safeguardingthe safety and health of employees and other persons who may be affected by the workbeing carried out Stakeholders refer to persons who create and have management orcontrol over WSH risks and not necessarily referring to occupiers and employers only

2 A concept that requires employers to weigh the degree of risk against the time trouble cost and physical

difficulty of taking measures to avoid the risk

Phase 1Factories Construction

Shipyard and Ship BuildingAirport Laboratories

Phase 2Hotels and RestaurantsVeterinary Healthcare

Logistics WasteManagement Landscape

Three major underlying principles of the WSH Act

1 Reducing risks at source by requiring all stakeholders to eliminate or minimisethe WSH risks they create or have control over at the workplace

2 Instilling greater industry ownership of WSH standards The focus will be shiftedfrom complying with prescriptive requirements to making employers responsiblefor developing safe work procedures suited to their particular situations in orderto achieve desired safety outcomes

3 Preventing accidents through higher penalties for poor WSH management

Stakeholders defined under the WSH Act also include principals manufacturers andsuppliers persons who erect install or maintain equipment and machinery as well asemployees At any one time a person might play different roles and hence have differentduties For instance a person can be an occupier an employer and a principal at the sametime in the same workplace

Annexes A and B provide more details on the definitions and duties of each stakeholderunder the WSH Act

Table 1 illustrates who are the different stakeholders and their duties under the WSH Actusing the example of a retail outlet

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

3 The list of statutory machinery or equipment and hazardous substances are listed in the Fifth Schedule of the

WSHA

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

Risk Control

When the existing control measures are not adequateList down additional control measures if any to eliminate the hazards orreduce the risk by following the Hierarchy of Control Measures (refer toSection 22)

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Introduction

One of the important steps in achieving the outcome of a ldquosafe and healthy workplace for allrdquois the progressive extension of the Workplace Safety and Health (WSH) Act 2006 to allworkplaces All workplaces in Singapore will be covered under the WSH Act by 2011 The

extension of the Act will cover the remaining workplaces which include wholesale and retailtrade public administration business services finance and insurance activities educationalinstitutes and fishing and agriculture sector The Act signifies a call to all stakeholdersregardless of the nature of business to play a part in creating a safe and healthy workplacefor everyone and making Singapore renowned for best practices in workplace safety andhealth

Many WSH hazards are not unique to particular industries or workplaces whether it is aconstruction worksite shipyard factory hotel healthcare facility or office For the industriesthat are already covered under the WSH Act1 the extension of Act in 2011 also sends astrong signal that while higher risk industries or work activities should remain as areas offocus no WSH hazards or risk should be neglected

This guide aims to(a) raise awareness on legal duties and liabilities from the perspective of safety and health

legislation(b) provide a better understanding on the common WSH hazards and the associated

prevention measures and(c) provide guidance on managing WSH hazards and risks through risk management and

WSH management systems

This guide is divided into four sections Section One summarises the key general duties ofemployers and employees stipulated under WSH Act 2006 Section Two provides a generaloverview of WSH (Risk Management) Regulations and the basic steps in risk managementand risk assessment Section Three lists the common safety and health hazards across allsectors and the corresponding prevention measures that can be taken Section Four

describes the WSH management programme which would ensure a systematic and effectivemanagement of safety and health

Providing and maintaining a safe and healthy workplace has numerous benefits includingreducing work injury compensation payouts decreasing absenteeism lessen the need forhiring replacement employees or replacing damaged equipment increasing productivityenhancing well-being and improving work morale among employees Use this guide to assistyou to start creating a safer and healthier workplace for all

1 Industries covered under Phase 1 mirrored those of the Factories Act ie factories construction sites shipyard

and shipbuilding and laboratories Industries covered under Phase 2 included hotels and restaurants logisticsveterinary healthcare cleaning and custodial services and water supply sewerage and waste managementsectors

Chapter 1 WSH Legislation 1 Overview of the WSH Act

On 1 March 2006 the Workplace Safety and Health (WSH) Act replaced the 33-year-oldFactories Act This Act signified a shift from the prescriptive legislative approach to a

performance-based regime The WSH Act emphasises on proactive WSH management byrequiring all stakeholders to identify hazards at the workplace and take reasonablypracticable measures2 to mitigate them The key features of the WSH Actbull Assigns responsibilities and liabilities to a broad range of stakeholdersbull Focuses on WSH systems and outcomes andbull Imposes higher penalties for non-compliant and risk-taking behaviour

These are based on the premise that accidents can only be prevented if all stakeholders inthe workplace take personal responsibility for achieving higher safety and health standardsSince the enactment of the Act in 2006 the coverage of workplaces has progressivelyexpanded from those covered under the Factories Act ie high-risk workplaces to includesix new sectors as below The WSH Act will be extended to all workplaces by 2011

11 Duties and Responsibilities of Stakeholders

The WSH Act assigns duties and liabilities to a wide range of stakeholders in safeguardingthe safety and health of employees and other persons who may be affected by the workbeing carried out Stakeholders refer to persons who create and have management orcontrol over WSH risks and not necessarily referring to occupiers and employers only

2 A concept that requires employers to weigh the degree of risk against the time trouble cost and physical

difficulty of taking measures to avoid the risk

Phase 1Factories Construction

Shipyard and Ship BuildingAirport Laboratories

Phase 2Hotels and RestaurantsVeterinary Healthcare

Logistics WasteManagement Landscape

Three major underlying principles of the WSH Act

1 Reducing risks at source by requiring all stakeholders to eliminate or minimisethe WSH risks they create or have control over at the workplace

2 Instilling greater industry ownership of WSH standards The focus will be shiftedfrom complying with prescriptive requirements to making employers responsiblefor developing safe work procedures suited to their particular situations in orderto achieve desired safety outcomes

3 Preventing accidents through higher penalties for poor WSH management

Stakeholders defined under the WSH Act also include principals manufacturers andsuppliers persons who erect install or maintain equipment and machinery as well asemployees At any one time a person might play different roles and hence have differentduties For instance a person can be an occupier an employer and a principal at the sametime in the same workplace

Annexes A and B provide more details on the definitions and duties of each stakeholderunder the WSH Act

Table 1 illustrates who are the different stakeholders and their duties under the WSH Actusing the example of a retail outlet

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

3 The list of statutory machinery or equipment and hazardous substances are listed in the Fifth Schedule of the

WSHA

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

4Refer to Annex C Methodology of Risk Assessment for MOM recommended ranking and criteria on likelihood

Risk Control

When the existing control measures are not adequateList down additional control measures if any to eliminate the hazards orreduce the risk by following the Hierarchy of Control Measures (refer toSection 22)

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Figure 2 Hierarchy of Controls

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Introduction

One of the important steps in achieving the outcome of a ldquosafe and healthy workplace for allrdquois the progressive extension of the Workplace Safety and Health (WSH) Act 2006 to allworkplaces All workplaces in Singapore will be covered under the WSH Act by 2011 The

extension of the Act will cover the remaining workplaces which include wholesale and retailtrade public administration business services finance and insurance activities educationalinstitutes and fishing and agriculture sector The Act signifies a call to all stakeholdersregardless of the nature of business to play a part in creating a safe and healthy workplacefor everyone and making Singapore renowned for best practices in workplace safety andhealth

Many WSH hazards are not unique to particular industries or workplaces whether it is aconstruction worksite shipyard factory hotel healthcare facility or office For the industriesthat are already covered under the WSH Act1 the extension of Act in 2011 also sends astrong signal that while higher risk industries or work activities should remain as areas offocus no WSH hazards or risk should be neglected

This guide aims to(a) raise awareness on legal duties and liabilities from the perspective of safety and health

legislation(b) provide a better understanding on the common WSH hazards and the associated

prevention measures and(c) provide guidance on managing WSH hazards and risks through risk management and

WSH management systems

This guide is divided into four sections Section One summarises the key general duties ofemployers and employees stipulated under WSH Act 2006 Section Two provides a generaloverview of WSH (Risk Management) Regulations and the basic steps in risk managementand risk assessment Section Three lists the common safety and health hazards across allsectors and the corresponding prevention measures that can be taken Section Four

describes the WSH management programme which would ensure a systematic and effectivemanagement of safety and health

Providing and maintaining a safe and healthy workplace has numerous benefits includingreducing work injury compensation payouts decreasing absenteeism lessen the need forhiring replacement employees or replacing damaged equipment increasing productivityenhancing well-being and improving work morale among employees Use this guide to assistyou to start creating a safer and healthier workplace for all

1 Industries covered under Phase 1 mirrored those of the Factories Act ie factories construction sites shipyard

and shipbuilding and laboratories Industries covered under Phase 2 included hotels and restaurants logisticsveterinary healthcare cleaning and custodial services and water supply sewerage and waste managementsectors

Chapter 1 WSH Legislation 1 Overview of the WSH Act

On 1 March 2006 the Workplace Safety and Health (WSH) Act replaced the 33-year-oldFactories Act This Act signified a shift from the prescriptive legislative approach to a

performance-based regime The WSH Act emphasises on proactive WSH management byrequiring all stakeholders to identify hazards at the workplace and take reasonablypracticable measures2 to mitigate them The key features of the WSH Actbull Assigns responsibilities and liabilities to a broad range of stakeholdersbull Focuses on WSH systems and outcomes andbull Imposes higher penalties for non-compliant and risk-taking behaviour

These are based on the premise that accidents can only be prevented if all stakeholders inthe workplace take personal responsibility for achieving higher safety and health standardsSince the enactment of the Act in 2006 the coverage of workplaces has progressivelyexpanded from those covered under the Factories Act ie high-risk workplaces to includesix new sectors as below The WSH Act will be extended to all workplaces by 2011

11 Duties and Responsibilities of Stakeholders

The WSH Act assigns duties and liabilities to a wide range of stakeholders in safeguardingthe safety and health of employees and other persons who may be affected by the workbeing carried out Stakeholders refer to persons who create and have management orcontrol over WSH risks and not necessarily referring to occupiers and employers only

2 A concept that requires employers to weigh the degree of risk against the time trouble cost and physical

difficulty of taking measures to avoid the risk

Phase 1Factories Construction

Shipyard and Ship BuildingAirport Laboratories

Phase 2Hotels and RestaurantsVeterinary Healthcare

Logistics WasteManagement Landscape

Three major underlying principles of the WSH Act

1 Reducing risks at source by requiring all stakeholders to eliminate or minimisethe WSH risks they create or have control over at the workplace

2 Instilling greater industry ownership of WSH standards The focus will be shiftedfrom complying with prescriptive requirements to making employers responsiblefor developing safe work procedures suited to their particular situations in orderto achieve desired safety outcomes

3 Preventing accidents through higher penalties for poor WSH management

Stakeholders defined under the WSH Act also include principals manufacturers andsuppliers persons who erect install or maintain equipment and machinery as well asemployees At any one time a person might play different roles and hence have differentduties For instance a person can be an occupier an employer and a principal at the sametime in the same workplace

Annexes A and B provide more details on the definitions and duties of each stakeholderunder the WSH Act

Table 1 illustrates who are the different stakeholders and their duties under the WSH Actusing the example of a retail outlet

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

3 The list of statutory machinery or equipment and hazardous substances are listed in the Fifth Schedule of the

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

4Refer to Annex C Methodology of Risk Assessment for MOM recommended ranking and criteria on likelihood

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 1 WSH Legislation 1 Overview of the WSH Act

On 1 March 2006 the Workplace Safety and Health (WSH) Act replaced the 33-year-oldFactories Act This Act signified a shift from the prescriptive legislative approach to a

performance-based regime The WSH Act emphasises on proactive WSH management byrequiring all stakeholders to identify hazards at the workplace and take reasonablypracticable measures2 to mitigate them The key features of the WSH Actbull Assigns responsibilities and liabilities to a broad range of stakeholdersbull Focuses on WSH systems and outcomes andbull Imposes higher penalties for non-compliant and risk-taking behaviour

These are based on the premise that accidents can only be prevented if all stakeholders inthe workplace take personal responsibility for achieving higher safety and health standardsSince the enactment of the Act in 2006 the coverage of workplaces has progressivelyexpanded from those covered under the Factories Act ie high-risk workplaces to includesix new sectors as below The WSH Act will be extended to all workplaces by 2011

11 Duties and Responsibilities of Stakeholders

The WSH Act assigns duties and liabilities to a wide range of stakeholders in safeguardingthe safety and health of employees and other persons who may be affected by the workbeing carried out Stakeholders refer to persons who create and have management orcontrol over WSH risks and not necessarily referring to occupiers and employers only

2 A concept that requires employers to weigh the degree of risk against the time trouble cost and physical

difficulty of taking measures to avoid the risk

Phase 1Factories Construction

Shipyard and Ship BuildingAirport Laboratories

Phase 2Hotels and RestaurantsVeterinary Healthcare

Logistics WasteManagement Landscape

Three major underlying principles of the WSH Act

1 Reducing risks at source by requiring all stakeholders to eliminate or minimisethe WSH risks they create or have control over at the workplace

2 Instilling greater industry ownership of WSH standards The focus will be shiftedfrom complying with prescriptive requirements to making employers responsiblefor developing safe work procedures suited to their particular situations in orderto achieve desired safety outcomes

3 Preventing accidents through higher penalties for poor WSH management

Stakeholders defined under the WSH Act also include principals manufacturers andsuppliers persons who erect install or maintain equipment and machinery as well asemployees At any one time a person might play different roles and hence have differentduties For instance a person can be an occupier an employer and a principal at the sametime in the same workplace

Annexes A and B provide more details on the definitions and duties of each stakeholderunder the WSH Act

Table 1 illustrates who are the different stakeholders and their duties under the WSH Actusing the example of a retail outlet

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

3 The list of statutory machinery or equipment and hazardous substances are listed in the Fifth Schedule of the

WSHA

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

Potential slip and tripsSources

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 1 WSH Legislation 1 Overview of the WSH Act

On 1 March 2006 the Workplace Safety and Health (WSH) Act replaced the 33-year-oldFactories Act This Act signified a shift from the prescriptive legislative approach to a

performance-based regime The WSH Act emphasises on proactive WSH management byrequiring all stakeholders to identify hazards at the workplace and take reasonablypracticable measures2 to mitigate them The key features of the WSH Actbull Assigns responsibilities and liabilities to a broad range of stakeholdersbull Focuses on WSH systems and outcomes andbull Imposes higher penalties for non-compliant and risk-taking behaviour

These are based on the premise that accidents can only be prevented if all stakeholders inthe workplace take personal responsibility for achieving higher safety and health standardsSince the enactment of the Act in 2006 the coverage of workplaces has progressivelyexpanded from those covered under the Factories Act ie high-risk workplaces to includesix new sectors as below The WSH Act will be extended to all workplaces by 2011

11 Duties and Responsibilities of Stakeholders

The WSH Act assigns duties and liabilities to a wide range of stakeholders in safeguardingthe safety and health of employees and other persons who may be affected by the workbeing carried out Stakeholders refer to persons who create and have management orcontrol over WSH risks and not necessarily referring to occupiers and employers only

2 A concept that requires employers to weigh the degree of risk against the time trouble cost and physical

difficulty of taking measures to avoid the risk

Phase 1Factories Construction

Shipyard and Ship BuildingAirport Laboratories

Phase 2Hotels and RestaurantsVeterinary Healthcare

Logistics WasteManagement Landscape

Three major underlying principles of the WSH Act

1 Reducing risks at source by requiring all stakeholders to eliminate or minimisethe WSH risks they create or have control over at the workplace

2 Instilling greater industry ownership of WSH standards The focus will be shiftedfrom complying with prescriptive requirements to making employers responsiblefor developing safe work procedures suited to their particular situations in orderto achieve desired safety outcomes

3 Preventing accidents through higher penalties for poor WSH management

Stakeholders defined under the WSH Act also include principals manufacturers andsuppliers persons who erect install or maintain equipment and machinery as well asemployees At any one time a person might play different roles and hence have differentduties For instance a person can be an occupier an employer and a principal at the sametime in the same workplace

Annexes A and B provide more details on the definitions and duties of each stakeholderunder the WSH Act

Table 1 illustrates who are the different stakeholders and their duties under the WSH Actusing the example of a retail outlet

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

3 The list of statutory machinery or equipment and hazardous substances are listed in the Fifth Schedule of the

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

bull Maintain adequate space in work areaparticularly the common passageways

bull Educate and inculcate safety culture

Strike against sharp objects such asprotruding nails

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

12 WSH (Risk Management) Regulations

Risk Management is a key component to reduce hazards at source The WSH (RiskManagement) Regulations imposes risk management duties on employers self-employedpersons and principals (including contractors and subcontractors) These parties areresponsible for identifying safety and health hazards at the workplace and taking reasonablypracticable measures to eliminate the hazards or reduce the risks associated with thehazards

Under the WSH (Risk Management) Regulations it is required to conduct a review on therisk assessment every three years or earlier if any of the following takes placebull An accident as a result of exposure to a hazard

bull Changes in work processes (eg introduction of new machinery equipment orsubstance) or

bull New information in relation to a hazard arises (eg toxicology data regarding asubstance)

Risk Management entailsa Identifying all WSH hazards associated with the work activityb Evaluating the risk levels for each identified WSH hazardc Control and monitoring the identified risksd Communicating these risks to all persons involved

Refer to Chapter 2 for definitions and details of risk management and assessment

14 Work Injury Compensation Act (WICA)

WICA replaces the Workmenrsquos Compensation Act from 1 April 2008 and is enforced by theWork Injury Compensation Department Ministry of Manpower WICA covers all employeesand provides for compensation to an employee for an injury or occupational disease arisingout of and in the course of his employment Work injury compensation comprises of medicalleave wages for the period that the employee is on medical leave medical expenses andora lump sum payment (for permanent incapacity or death only)

Unless specifically exempted all employers are required to purchase work injurycompensation insurance fori Employees who perform manual work (regardless of their level of earnings) orii Non-manual employees with monthly income equal or less than $1600

For employees who are newly covered under the Act (ie non-manual employees earningabove $1600 a month) for all other employees the employers have the flexibility to decidewhether or not to buy work injury compensation insurance for them Nonetheless employerswill be required to pay compensation (including medical leave wages and medical expenses)in the event of a valid claim even if they do not buy insurance

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

bull Maintain adequate space in work areaparticularly the common passageways

bull Educate and inculcate safety culture

Strike against sharp objects such asprotruding nails

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Duties of the Self-employed PersonIt is the duty of the self-employed person to take measures as far as it being reasonablypracticable to ensure the safety and health of others such as members of the public or hisown employees

Definition of ldquoReasonably PracticablerdquoThe term ldquoreasonably practicablerdquo means that the degree of risk in a particular situationcan be balanced against the time trouble cost and physical difficulty of taking measuresto avoid the risk

An action is considered to be practicable when it is capable of being done It takes intoaccountbull The severity of any injury or harm to health that may occurbull The degree of risk (or likelihood) of that injury or harm occurringbull How much is known about the hazard and the ways of eliminating reducing or

controlling itbull The availability suitability and cost of the safeguardsbull The cost of putting safeguards in place needs to be measured against the

consequences of failing to do so Whether the employer can afford to put thenecessary safeguards in place is not a consideration particularly where there isrisk of serious injury or frequent but less severe injury

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

with a safety mark sign indicatedbull Engage electrical workers (licensed by EMA) to carry out electrical worksbull Read relevant instruction manuals prior to operating electrical appliances

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

4Refer to Annex C Methodology of Risk Assessment for MOM recommended ranking and criteria on likelihood

severity and risk level

Risk Control

When the existing control measures are not adequateList down additional control measures if any to eliminate the hazards orreduce the risk by following the Hierarchy of Control Measures (refer toSection 22)

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Figure 2 Hierarchy of Controls

EliminationElimination of hazards refers to the total removal of the hazards and hence effectivelymaking all the identified possible accidents and ill health impossible This is a permanent

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

Potential slip and tripsSources

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Employers or occupiers who reported a workplace incident are also required to keep recordsof the incident for at least three years

14 Work Injury Compensation Act (WICA)

WICA replaces the Workmenrsquos Compensation Act from 1 April 2008 and is enforced by theWork Injury Compensation Department Ministry of Manpower WICA covers all employeesand provides for compensation to an employee for an injury or occupational disease arisingout of and in the course of his employment Work injury compensation comprises of medicalleave wages for the period that the employee is on medical leave medical expenses andora lump sum payment (for permanent incapacity or death only)

Unless specifically exempted all employers are required to purchase work injurycompensation insurance fori Employees who perform manual work (regardless of their level of earnings) orii Non-manual employees with monthly income equal or less than $1600

For employees who are newly covered under the Act (ie non-manual employees earningabove $1600 a month) for all other employees the employers have the flexibility to decidewhether or not to buy work injury compensation insurance for them Nonetheless employerswill be required to pay compensation (including medical leave wages and medical expenses)in the event of a valid claim even if they do not buy insurance

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Risk Control

When the existing control measures are not adequateList down additional control measures if any to eliminate the hazards orreduce the risk by following the Hierarchy of Control Measures (refer toSection 22)

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Figure 2 Hierarchy of Controls

EliminationElimination of hazards refers to the total removal of the hazards and hence effectivelymaking all the identified possible accidents and ill health impossible This is a permanent

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

bull Maintain adequate space in work areaparticularly the common passageways

bull Educate and inculcate safety culture

Strike against sharp objects such asprotruding nails

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

controlling itbull The availability suitability and cost of the safeguardsbull The cost of putting safeguards in place needs to be measured against the

consequences of failing to do so Whether the employer can afford to put thenecessary safeguards in place is not a consideration particularly where there isrisk of serious injury or frequent but less severe injury

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

4Refer to Annex C Methodology of Risk Assessment for MOM recommended ranking and criteria on likelihood

severity and risk level

Risk Control

When the existing control measures are not adequateList down additional control measures if any to eliminate the hazards orreduce the risk by following the Hierarchy of Control Measures (refer toSection 22)

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Figure 2 Hierarchy of Controls

EliminationElimination of hazards refers to the total removal of the hazards and hence effectivelymaking all the identified possible accidents and ill health impossible This is a permanent

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Flammable LiquidStorage and Handling

Store flammable liquids in fire safety cabinets and to a minimumamountEnsure appropriate fire extinguishing agents are available

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 2 Risk Management

2 Overview of Risk Management

Risk management comprises risk assessment risk monitoring and risk communicationProactive and effective management of WSH calls for not only the risk assessment processbut periodic monitoring of the risks and communicating to all involved persons as wellMonitoring is essential to ensure that the measures put in place are indeed effective Two-way communication also ensures persons involved understand the risks associated with theworks and at the same time it provides feedback to the management This continuousprocess is essential in ensuring a continual improvement in the safety and health status of aworkplace

21 Risk Assessment

Risk assessment is a tool that provides a systematic approach in recognising hazards due toa job or task evaluating the risks and implementing all reasonably practicable measures toprevent accidents from happening To put it in a more simply the tool demands one to thinkwhat could go wrong before and while carrying out his or her work and determine if adequate

measures are in place to prevent a mishap

Risk assessment comprises three steps ie hazard identification risk evaluation and riskcontrols Two terms used in risk assessment ie hazard and risk are defined as

bull Hazardmdashany source that has the potential to cause harm or adverse effect onsomeone or something (eg injury illness and property damage) It includeschemical mechanical physical electrical and ergonomic hazards

bull Riskmdashthe possibility or probability that one would be harmed or suffer from anadverse effect if exposed to a hazard with the consequence of the exposure takeninto consideration It may also apply to situations with property or equipment loss ordamage

22 Basic Steps to Carry Out Risk Assessment and Risk ManagementSteps to carry out risk assessment and risk management can be summarised as follows

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

4Refer to Annex C Methodology of Risk Assessment for MOM recommended ranking and criteria on likelihood

Risk Control

When the existing control measures are not adequateList down additional control measures if any to eliminate the hazards orreduce the risk by following the Hierarchy of Control Measures (refer toSection 22)

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Figure 2 Hierarchy of Controls

EliminationElimination of hazards refers to the total removal of the hazards and hence effectivelymaking all the identified possible accidents and ill health impossible This is a permanent

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

Potential struck by or against objectsources

Recommended preventive measures

Overstacked or overloaded shelves

Figure 7 Falling Shelves

bull Do not store boxes papers and othermaterials on top of lockers or file cabinets

bull Stack material in such a way that it isstable and not fall over

bull Mark glass door with prominent features tomake them apparent

Figure 9 Marking of Glass Door

Bumping into person or permanent objector strike against open file drawers or opencabinet door

bull Maintain adequate space in work areaparticularly the common passageways

bull Educate and inculcate safety culture

Strike against sharp objects such asprotruding nails

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Definition of ldquoReasonably PracticablerdquoThe term ldquoreasonably practicablerdquo means that the degree of risk in a particular situationcan be balanced against the time trouble cost and physical difficulty of taking measuresto avoid the risk

An action is considered to be practicable when it is capable of being done It takes intoaccountbull The severity of any injury or harm to health that may occurbull The degree of risk (or likelihood) of that injury or harm occurringbull How much is known about the hazard and the ways of eliminating reducing or

controlling itbull The availability suitability and cost of the safeguardsbull The cost of putting safeguards in place needs to be measured against the

consequences of failing to do so Whether the employer can afford to put thenecessary safeguards in place is not a consideration particularly where there isrisk of serious injury or frequent but less severe injury

Steps Explanation

Preparation stage

Form a riskassessment team

bull An appointed team leader with good knowledge of the work toassess risk assessment methodology

bull

Team members with good knowledge of the work to be assessedand basic understanding of risk assessment methodologybull Team should comprise management staff technical personnel

supervisors maintenance staffs safety personnel (if available) andcontractor or supplier (if applicable)

bull Alternative may engage WSH consultant to assist

Gather relevantinformation

Collate all information May include but not limited tobull Layout planbull List of work activitiesbull List of chemicals usedbull List of machinery and tools usedbull Records of past incidents and accidentsbull Relevant legislation codes of practice or relevant specificationsbull Feedback from staff clients suppliers or other stakeholdersbull Manufacturerrsquos instruction manual or document (eg safety data

sheet for chemicals)

Hazard Identification

Hazardidentification

bull List the sequence of the steps required to complete a taskbull Brainstorm on all the possible hazard associated with each step for

example working at height working with harsh chemical andstanding for long hours

bull List the possible accidents or incidents for example fall from heightskin disease back strain (note there can be more than one outcomefor each hazard)

bull

Determine the persons who may be affected by the activity forexample persons performing the task passers-by andor visitors

Risk evaluation4

Likelihood

List down all the current measures that have been put in place forexample inspection of ladder before use use of gloves and take frequentbreaksFor each hazard determine the likelihood of the accidents or incidents tooccur with existing control measures being taken into account

SeverityDetermine the extent of injury or harm due to the accidents or incidentsDoes not take existing control measures into account that is to considerthe inherent effect of the adverse effect due to the hazard

Risk Level

A function of likelihood and severity

Allows management to recognise areas of high risks along with prioritygiven when allocating resources in addressing the risks

4Refer to Annex C Methodology of Risk Assessment for MOM recommended ranking and criteria on likelihood

severity and risk level

Risk Control

When the existing control measures are not adequateList down additional control measures if any to eliminate the hazards orreduce the risk by following the Hierarchy of Control Measures (refer toSection 22)

Review Communication and Recordkeeping

Endorsement andApproval

Ensure the risk assessment results are discussed endorsed andapproved by top or senior management

ReviewTo review the risk assessment every three years or earlier if any of thefollowing occursmdashan incident new information on safety and health riskssurfaces or changes in the work area process equipment machinery orsubstance

CommunicateCommunicate the results of the risk assessment to all persons who areinvolved in the work

Recordkeeping Document the risk assessment results for at least three years

22 Hierarchy of Control

The control of hazards and reduction of risks can be accomplished by following theHierarchy of Control Measures shown in Figure 1 It is important to bear in mind that thesecontrol measures are not usually mutually exclusive for example engineering controls canbe implemented together with administrative controls like training and safe work procedures

Figure 2 Hierarchy of Controls

EliminationElimination of hazards refers to the total removal of the hazards and hence effectivelymaking all the identified possible accidents and ill health impossible This is a permanent

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

Potential struck by or against objectsources

Recommended preventive measures

bull Educate and inculcate safety culture

Strike against sharp objects such asprotruding nails

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

External sources for example trafficgeneral industrial noise

Install double-glazed windows and solid walls

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

Potential slip and tripsSources

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

Potential struck by or against objectsources

Recommended preventive measures

Overstacked or overloaded shelves

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 3 Common WSH Hazards

3 Overview

Work-related injuries and diseases occur as a result of unsafe acts and unsafe conditionsUnsafe acts usually occur when employees are unaware of hazards or the proper work

practices Examples include not adopting the proper methods when lifting heavy objects ornot using gloves when handling hazardous chemicals Unsafe conditions refer to hazardousphysical conditions of the work environment and equipment Examples include a slipperyfloor or a poorly ventilated office Work-related accidents and illness can be prevented byrecognising the hazards associated with the task to be undertaken and taking the necessaryprevention measures

Common workplace safety and health hazards include Falls from height31 Slips and trips on same level32 Struck by or against objects33 Electrical hazard34 Manual handling hazard35 Chemical hazard

36 Noise hazard37 Indoor air quality issue38 Fatigue39 Fire hazard310 Confined space hazard

In the following sections we will be looking at these common WSH hazards and howaccidents arising from these hazards can be prevented

31 Slips Trips and Falls

Employees slipping and falling on slippery floors or tripping and falling over physicalobstructions are one of the most common forms of workplace accidents The extent of injury

due to slip trip and fall cases can range from minor sprains and strains to bone fracturesand head injuries

311 Sources of slips trips and fallsMajority of slips trips and falls can be attributed to

bull Wet or contaminated walking surfaces (eg liquids dusts and grease)bull Uneven walking surface potholes changes in level broken or cracked flooringbull Uneven placement loose or wrinkled carpet mats or rugs orbull Obstruction or protruding objects in walkways (eg boxes cables and open drawer)

Factors that can enhance the likelihood of slip trip and fall incidents include insufficient

lighting poor housekeeping wearing wrong type of footwear rushing and carelessness andpoor sense of stability due to age or medication

Fast Fact Top three causes ofworkplace injuries acrossindustries

Falls from height Slips and trips Struck by falling objects

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

Potential struck by or against objectsources

Recommended preventive measures

bull Educate and inculcate safety culture

Strike against sharp objects such asprotruding nails

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Figure 10 Use of Anti-fatigue Mats

Fast Fact Schedule lessdemanding activities to act as

active breaks in betweendemanding tasks are

beneficial they reduceboredom stress and fatigue

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

Potential struck by or against objectsources

Recommended preventive measures

Overstacked or overloaded shelves

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

Recommended preventive measures

Uneven walking surfacespotholes changes in levelbroken or cracked flooring

bull Encourage employees to report unsafe conditionsbull Incorporate high visible tread makers such as

reflective edges or floor marking to highlightchanges in level or slope

Uneven placement loose orwrinkled carpets mats or rugs

bull Ensure carpets and rugs are free of holes andloose edges

Obstruction or protruding objectsin walkways (eg boxes cablesand open drawer)

bull Keep work area neatmdashdo not leave materials andboxes lying haphazardly around

bull Keep drawers or doors of cabinets closed afteruse

bull Position equipment with cord to avoid power cordscrossing pedestriansrsquo routes or use cable cover tosecure power cords to surfaces

32 Falls from Height

While falls from height cases are often associated with construction and shipyard industry (itis the largest cause of death for employees in the building construction and shipyardindustry) many cases happened in less risky circumstances such as changing of light bulbsor retrieving of items from high shelves Similar to slips trips and falls possible injuries dueto falls from low height can range from minor sprains to head injuries and broken bones It istherefore important that one not only exercises common sense but take the necessaryprecautionary measures (no matter how minor the job may seem to be) prior to carrying outactivities involving working at height

321 Sources of Falls from Height

As a general rule any work activity that involves access to positions that cannot be reachedwhen standing on the ground should be regarded as work at height Falls from height canbe due to

bull using chair or unstable equipment as ascending toolbull using ladder in an improper manner orbull using defective ladders

322 Measures to Prevent Falls Safe Use of Portable Ladders

While portable ladders are very common and useful tools users often tend to overlook thepotential hazards associated with them Accidents associated with portable ladders areusually caused by improper selection care or use

Different portable ladders are designed with different maximum intended load Select onethat is appropriate in size and for the task at hand Some other prevention tips include

bull Inspect ladders before and after each use Things to look out for include loosescrews nuts and bolts and hinges

bull Make sure that the feet and rungs are in a good condition and clear of grease or soilbull Position ladder on hard even-levelled surface using slip-resistant feet or secure

blocking or have someone hold the ladderbull Make sure the locks and braces are fixed and properly engagedbull Face the ladder when standing or climbing on it

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

Potential struck by or against objectsources

Recommended preventive measures

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

with a safety mark sign indicatedbull Engage electrical workers (licensed by EMA) to carry out electrical worksbull Read relevant instruction manuals prior to operating electrical appliances

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

33 Struck By or Against Objects

In 2008 injuries due to struck by and against objects accounted for approximately one-thirdof the total workplace injuries Accidents due to struck by or against objects can occur in anywork setting Injuries sustained due to struck by falling objects depend on the weight of theobjects and the height from which the objects fell from On the other hand injuries sustaineddue to strike against object depends on the impact force during the point of collision Thus

injuries due to struck by or against object can range from minor bruises to serious injuriessuch as head injuries and bone fractures

331 Sources of Struck By or Against Objects

A ldquostruck byrdquo injury refers to an injury as a result of being hit by falling or flying objects orbeing struck by another person Possible situations whereby persons may get struck byobjects includebull Overloaded storage shelves racks or cabinetsbull Retrieving items stored above eye level and without using step stool or ladderbull Inadequate warnings of overhead works eg object falling off from overhead

platform and striking employee standing underneathbull Overhead fixtures eg pictures ceiling fan and ceiling boards not properly secured

Injury due to ldquostruck againstrdquo refers to injury from impacting objects during movement forexample bumping into a glass door persons or against protruding objects

331 Measures to preventing struck by or against objects

Potential struck by or against objectsources

Recommended preventive measures

Overstacked or overloaded shelves

Figure 7 Falling Shelves

bull Do not store boxes papers and othermaterials on top of lockers or file cabinets

bull Stack material in such a way that it isstable and not fall over

bull Do not overload shelves and storagecabinets

bull Regular inspections to detect and rectifyany unsafe stacking

bull Maintain adequate space in work areabull Regular inspection to detect and rectify

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Figure 10 Use of Anti-fatigue Mats

Fast Fact Schedule lessdemanding activities to act as

active breaks in betweendemanding tasks are

beneficial they reduceboredom stress and fatigue

Use of anti-fatigue mat helps to relieve strains on back foremployees who need to stand for prolonged periods

Work Surface

bull Position frequently assessed items (eg telephone) at minimal reach distancebull Clear clutter below the workstation to allow room for movement and leg stretchingbull If one is using a document holder position it at the same distance and height as the

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

any unsafe condition

Prevent being struck by falling objects in the wholesale and retail trades

More and more wholesale and retail sectors are storing higher volumes of stocks onthe retail sales floor to reduce cost of storage space With the higher volume ofstocks and limited space merchandises tend to be stacked high Stackingmerchandise high not only poses higher risk to employees but also to customersvisiting the workplace

Recommended preventive measures include

bull Do not allow items to hang over the edge of a shelfbull Limit the stacking of topmost shelf to a single rowbull Make sure that all shelves are anchored securelybull Cordon off aisles when merchandise is being stockedbull Put up proper signs to request customers not to retrieve items from high

shelves and to seek assistance from employees

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Figure 10 Use of Anti-fatigue Mats

Fast Fact Schedule lessdemanding activities to act as

active breaks in betweendemanding tasks are

beneficial they reduceboredom stress and fatigue

Use of anti-fatigue mat helps to relieve strains on back foremployees who need to stand for prolonged periods

Office Ergonomics

Many office jobs are no longer computer independent Computer is not just used forcompleting work tasks but for communication purpose as well for example electronic mailsand instant messaging Along with the increasing use of palm devices employees arespending more and more time at the computer screen

Remember A properly set-up office workstation allows staff to maintain a comfortableneutral body posture and it reduces stress and strain on the muscles However there is nosingle ldquocorrectrdquo posture or arrangement that will fit everyone Use these tips on how toproperly set up computer and laptop workstations as the basic design goals

Proper Computer Workstation Setup

Figure 13 Proper Computer Workstation Setup

Monitor

bull Adjust monitor so that the top of the screen is at eye levelbull Place the monitor at a distance between 45 cm and 70 cmbull Place the centre of the screen at an angle of 15 degree down from your eyesbull Locate working documents between the keyboard and screen or next to the screen

Keyboard and Mouse

bull Adjust the keyboard height so that forearms are parallel to the floor or slightlydownward

bull Place the mouse immediately next to the keyboard and on the same levelbull Avoid using the keyboard supports to raise the back of the keyboard higher than the

frontbull Select the right mouse size and shape in accordance to usersbull Keep the shoulders relaxedmdashnot shrugged-up or slumped-down Chair and Sitting

bull Sit upright or slightly reclinedbull Use the chair back supportbull Adjust the chair so that the feet can rest completely on floor or use footrestbull Keep knees at near right angle (90ndash105 degree)

Work Surface

bull Position frequently assessed items (eg telephone) at minimal reach distancebull Clear clutter below the workstation to allow room for movement and leg stretchingbull If one is using a document holder position it at the same distance and height as the

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

34 Manual Handling

Manual handling can be defined as any activity requiring the use of force to lift lower pushpull carry or move a load (eg an object equipment person or animal) Manual handlingputs employees at the risk of musculoskeletal disorders (MSD) with sprains and strains onthe back being one of the most common MSD can affect parts including muscles jointstendons and nerves Symptoms of MSD include

bull Numbnessbull Painbull Swellingbull Tingling sensation

bull Weakness in affected body part andorbull Stiffness of joints

In many cases these injuries result in a temporary absence from work but MSD can lead topermanent disablement

341 Causes of MSDs

Handling of heavy loads increases the risk of injury Lifting loads over 25 kg regularly can

result in a higher risk of back injury A bulky object is more dangerous to lift because itcannot be brought close to the body therefore increasing the stress on different muscles Inaddition lifting a bulky object may force one into an awkward and unbalanced position orobstruct onersquos vision Correct lifting postures have to be adopted to minimise injuries

3411 Handling Heavy or Bulky Loads

Proper Lifting Techniques

Step 1 Assess the load and plan the lift Do you need help Can you use any liftingequipment Clear the path of any obstruction Place one foot at the side of the loadand one foot behind the load

Place one foot at the side of the load and one foot behind the load

Step 2 Bend your knees and keep your body straight Bring the object close to your bodygrasp the object firmly and hold the object close to the body Keep your arms chinand elbows as close to your body as possible Distribute your body weight equallyto both feet

Fast Fact MSDs canbe reversible Earlyintervention is the

key

Distribute your body weight equally to both feet

Step 3 Lift the object by pushing up on your legs Avoid jerking or twisting your back

Step 4 Ensure feet are stable Ensure a good grip on object before moving off Keep yourhead up while moving

Ensure a good grip on object before moving off

3412 Repetitive Movements

Repetitive movement becomes hazardous when the same joints and muscle groups areused in the same motion too often too quickly and for long duration Injuries occur whenthere is too much stress placed on a part of the body and there is no adequate time forrecovery Possible repetitive movement related injuries include inflammation pain andswelling muscle strain or tissue damage

Do NOT

bull lift with wet or oily hands bull turn by rotating the waist

bull lift heavy items if you are not in good physical condition bull jerk to lift an object off a surface bull drop an item to put it down bull run when carrying an object bull hurry up or down stairs or ramps or bull carry items by the straps or tapes

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Figure 10 Use of Anti-fatigue Mats

Fast Fact Schedule lessdemanding activities to act as

active breaks in betweendemanding tasks are

beneficial they reduceboredom stress and fatigue

Use of anti-fatigue mat helps to relieve strains on back foremployees who need to stand for prolonged periods

Office Ergonomics

Many office jobs are no longer computer independent Computer is not just used forcompleting work tasks but for communication purpose as well for example electronic mailsand instant messaging Along with the increasing use of palm devices employees arespending more and more time at the computer screen

Remember A properly set-up office workstation allows staff to maintain a comfortableneutral body posture and it reduces stress and strain on the muscles However there is nosingle ldquocorrectrdquo posture or arrangement that will fit everyone Use these tips on how toproperly set up computer and laptop workstations as the basic design goals

Proper Computer Workstation Setup

Figure 13 Proper Computer Workstation Setup

Monitor

bull Adjust monitor so that the top of the screen is at eye levelbull Place the monitor at a distance between 45 cm and 70 cmbull Place the centre of the screen at an angle of 15 degree down from your eyesbull Locate working documents between the keyboard and screen or next to the screen

Keyboard and Mouse

bull Adjust the keyboard height so that forearms are parallel to the floor or slightlydownward

bull Place the mouse immediately next to the keyboard and on the same levelbull Avoid using the keyboard supports to raise the back of the keyboard higher than the

frontbull Select the right mouse size and shape in accordance to usersbull Keep the shoulders relaxedmdashnot shrugged-up or slumped-down Chair and Sitting

bull Sit upright or slightly reclinedbull Use the chair back supportbull Adjust the chair so that the feet can rest completely on floor or use footrestbull Keep knees at near right angle (90ndash105 degree)

Work Surface

bull Position frequently assessed items (eg telephone) at minimal reach distancebull Clear clutter below the workstation to allow room for movement and leg stretchingbull If one is using a document holder position it at the same distance and height as the

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

External sources for example trafficgeneral industrial noise

Install double-glazed windows and solid walls

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Measures to prevent injuries due to repetitive movements

bull Plan work schedules such that employees can take regular breaks (effective breakscan be brief but must be regular)

bull Review work speed or load to ensure that the rate and target is realistic foremployees

bull Do simple stretching exercises to warm up and cool down working musclesbull Where possible allow for job rotation during one shift so that employees do not do a

particular task with the risk of repetitive injuries throughout the entire shiftbull Educate employees on risks and preventive measures

Work Surface

bull Position frequently assessed items (eg telephone) at minimal reach distancebull Clear clutter below the workstation to allow room for movement and leg stretchingbull If one is using a document holder position it at the same distance and height as the

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Remember A properly set-up office workstation allows staff to maintain a comfortableneutral body posture and it reduces stress and strain on the muscles However there is nosingle ldquocorrectrdquo posture or arrangement that will fit everyone Use these tips on how toproperly set up computer and laptop workstations as the basic design goals

Proper Computer Workstation Setup

Figure 13 Proper Computer Workstation Setup

Monitor

bull Adjust monitor so that the top of the screen is at eye levelbull Place the monitor at a distance between 45 cm and 70 cmbull Place the centre of the screen at an angle of 15 degree down from your eyesbull Locate working documents between the keyboard and screen or next to the screen

Keyboard and Mouse

bull Adjust the keyboard height so that forearms are parallel to the floor or slightlydownward

bull Place the mouse immediately next to the keyboard and on the same levelbull Avoid using the keyboard supports to raise the back of the keyboard higher than the

frontbull Select the right mouse size and shape in accordance to usersbull Keep the shoulders relaxedmdashnot shrugged-up or slumped-down Chair and Sitting

Work Surface

bull Position frequently assessed items (eg telephone) at minimal reach distancebull Clear clutter below the workstation to allow room for movement and leg stretchingbull If one is using a document holder position it at the same distance and height as the

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

External sources for example trafficgeneral industrial noise

Install double-glazed windows and solid walls

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

with a safety mark sign indicatedbull Engage electrical workers (licensed by EMA) to carry out electrical worksbull Read relevant instruction manuals prior to operating electrical appliances

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Work Surface

bull Position frequently assessed items (eg telephone) at minimal reach distancebull Clear clutter below the workstation to allow room for movement and leg stretchingbull If one is using a document holder position it at the same distance and height as the

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

External sources for example trafficgeneral industrial noise

Install double-glazed windows and solid walls

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

with a safety mark sign indicatedbull Engage electrical workers (licensed by EMA) to carry out electrical worksbull Read relevant instruction manuals prior to operating electrical appliances

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

computer monitor

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

External sources for example trafficgeneral industrial noise

Install double-glazed windows and solid walls

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Setting Up Laptop for Frequent Use

To avoid sprains and strains associated with prolonged use of laptop (ie more than twohours and continuously per day) it is recommended for employers to provide computerdocking stations and for employees to use them Docking stations comprises full sizemonitor keyboard and mouse with the laptop basically serving as the hard drive

An alternative option to the docking station is to position laptop screen at eye level height byusing a laptop riser and connect to an external keyboard All these avoid placing handsarms and wrists in awkward posture and the bending of neck and upper back

Other tips for laptop usersbull Avoid putting laptop directly on the thighs for a prolonged periodbull Carry laptop in a wheeled case or backpack with wide padded shoulder straps

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

35 Noise

Long term exposure to excessive noise may lead to hearing loss To prevent hearing loss aperson should not be exposed to noise levels exceeding 85 dBA for eight hours a day or itsequivalent Where the permissible exposure level is exceeded measures should be taken toreduce the noise exposure As a general guide at 85 dBA people will have to shout to beheard if they are about two metres apart

351 Recommended Noise Control Measures (for Noise Level at 85 dBA or above)

If activities carried out at the workplace subject employees to excessive noisy environmentthat is noise level above 85 dBA over eight hours employers are required to implementnoise control solutions based on the hierarchy of control

bull Elimination or substitution for example replace the machines or equipment withquieter ones

bull Engineering control for example erect enclosure lined with acoustics absorptionmaterial

bull Administrative control implement job rotationbull Personal protective equipment that is ear plug or ear muff

Table 3 Permissible exposure levels showing the corresponding length of time allowed forthe various noise levels

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

352 Recommended Noise Control Measures (for Nuisance Noise)

Noise within the office rarely exceeds the 85 dBA level however it can create annoyance tooffice employees and result in stress Effects of annoying noise include irritabilityimpairment in concentration tiredness and fatigue

Table 4 Recommended preventive measures in addressing nuisance noise at quiet

workplaces

Sources of Nuisance Noise withinOffices

Minimising Work Stress due to NuisanceNoise

People for example loudconversations and frequent loud phoneringing

Adopt administrative controls such asencouraging employees to use meeting room forconversations and lower ringing volume fortelephones

Office equipment for examplephotocopy machines telephones andprinters

Placing equipment in a separate room

Figure 16 Example of placing photocopier in aseparate room

Building for example air conditioningsystem lifts

Maintain equipments and machinery on periodicbasis

External sources for example trafficgeneral industrial noise

Install double-glazed windows and solid walls

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

36 Chemical

Depending on the nature of job employees may be required to handle industrial chemicalsthat are toxic flammable or corrosive Chemicals upon entering human body can lead to avariety of adverse health effects including immediate effects or long-term effects that isthey appear after a number of years after the exposure occurred The type and extent ofadverse health effects exerted by chemicals depends on

bull The intrinsic nature of the chemical for example some chemicals are naturally moretoxic than others

bull The routes of exposure that is how chemicals enter the human bodybull The physical form of the chemicals for example solids liquids gases or vapoursbull The frequency and length of exposurebull The concentration or level of exposurebull Individual factor that is some individuals are more sensitive to chemicals than

others

Disregarding the safety and health risks associated with the chemicals and improperhandling may cause illnesses and injuries

361 Routes of Exposure to Chemical and Prevention Measures

Chemicals can enter human body via four routesmdashbreathing in skin or eye absorptioningestion and injection Breathing in and skin absorption are the two most common routes ofexposure and injection the least common Swallowing chemicals is rare and is most likelyaccidental For example eating drinking or smoking after using chemicals and withoutwashing hands thoroughly Refer to Table 5 for examples of how one can be exposed tochemicals

Understanding the type of chemical being handled along with the correct handling method isthe key to prevent injury or illness resulting from chemical exposure Information about achemical can be identified from the label on containers andor safety data sheet (SDS) It isimportant that for all chemical users to read the label andor SDS prior to handing anychemical

The SDS document provides comprehensive information of chemical and can be requestedfrom chemical manufacturers or suppliers It is mandatory under the WSH legislation for allhazardous chemical manufacturers or suppliers to provide accurate SDS documents to theircustomers and for employers to share these documents with their employees

SDS is generally not available for everyday household chemicals Users should then refer tothe chemical labels

What are Safety Data Sheets (SDS)

A document prepared by hazardous chemical manufacturer or supplier whichprovides detailed information of a chemical

bull Chemical identitybull Health effectsbull Protective equipmentbull First aid measuresbull Fire fighting measures

Users should read and understand SDS before handling hazardous chemicals

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

with a safety mark sign indicatedbull Engage electrical workers (licensed by EMA) to carry out electrical worksbull Read relevant instruction manuals prior to operating electrical appliances

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

with a safety mark sign indicatedbull Engage electrical workers (licensed by EMA) to carry out electrical worksbull Read relevant instruction manuals prior to operating electrical appliances

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

37 Electrical

Electricity is a source of energy widely used to power and run many types of equipment andappliances Electrical appliances and equipment are generally safe for use if they aredesigned and manufactured to electrical standards and codes and if they have beenmaintained and kept in good condition Accident involving electricity can cause a range ofinjuries including electric shock electrical burns fires and explosions Non-fatal electricalshock can also lead to serious accidents such as falling from ladder or any elevated workplatform

An electric shock can range from slight tingling sensation to immediate cardiac arrest Theseverity of an electric shock depends on the following factorsbull The amount of current flowing through the bodybull The currentrsquos path through the body andbull The length of contact time

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

371 Sources of electrical hazards

Most electrical accidents occur due to one of these three factors ie unsafe equipment orinstallation unsafe environment or unsafe work practices Unsafe environment or workpractices are most often due to the overlook of the hazards posed by electricity Examples ofscenarios where chances of getting injured due to electrical hazards include

bull Overloading of power circuitsbull Handling electrical appliances with wet hands or on wet surfacesbull Using electrical equipment with worn out protective insulationsbull Unauthorized alteration of electrical equipment or parts

372 Measures to Prevent Electrical-related Injuries

Electrical installations must be installed in accordance with Singapore Standard CP5 Codeof Practice for Electrical Installations Such installations along with the servicing andmaintenance works should always be carried out by the electrical workers licensed by theEnergy Market Authority (EMA)

Though electrical appliances are common they do present electrical hazards if misused orabused

Some basic preventive measures include

bull Keep power cords away from heat water and oilbull Do not clean electrical equipment with flammable solvent eg acetonebull Do not overload electrical pointsbull Remove defective electrical appliances immediately Send them for repair or discard

thembull Provide a system for inspection and maintenance of electrical appliancesbull Avoid placing power cords under carpets or heavy furniturebull Use power sockets plugs and cables that are registered with Spring Singapore ie

with a safety mark sign indicatedbull Engage electrical workers (licensed by EMA) to carry out electrical worksbull Read relevant instruction manuals prior to operating electrical appliances

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

Electrical

bull Check and maintain electrical equipmentsbull Install additional power outlets to avoid overloading of power

circuitsbull Adhere to electrical equipment manufacturerrsquos

recommendations and instructions

Conventional Cooking

bull Follow electrical appliancesrsquo recommendations andinstructions

bull Never leave cooking unattended (if cooking allowed atworkplace)

Mechanical Friction

Maintain equipment on periodic basis eg lubrication aligned

and kept cleaned

Housekeeping

bull Prohibit storage of materials from blocking fire emergencyequipment eg exits fire extinguishers and sprinklers

bull Avoid excessive storage in workplace

Smoking

bull Prohibit all unauthorised smokingbull Proper setup of smoking areas eg immediate surrounding

free from flammable substances and with self-extinguishingbutt cans

Works that producesparks flames or slag

eg grinding andwelding

bull Establish safe work procedures prior to allowing any hot

works to be carried outbull Ensure the persons who carry out the works are competent

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

Page 44

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Definition of ldquoReasonably PracticablerdquoThe term ldquoreasonably practicablerdquo means that the degree of risk in a particular situationcan be balanced against the time trouble cost and physical difficulty of taking measuresto avoid the risk

An action is considered to be practicable when it is capable of being done It takes intoaccountbull The severity of any injury or harm to health that may occurbull The degree of risk (or likelihood) of that injury or harm occurringbull How much is known about the hazard and the ways of eliminating reducing or

controlling itbull The availability suitability and cost of the safeguardsbull The cost of putting safeguards in place needs to be measured against the

consequences of failing to do so Whether the employer can afford to put thenecessary safeguards in place is not a consideration particularly where there isrisk of serious injury or frequent but less severe injury

3102 Measures to Preventing Fire Hazards

Regardless of the size and nature of the business every workplace should have a fireprotection system in place It may range from a simple evacuation plan and provision of fireextinguisher to a complex system comprising a central controller trained personnel andimmediate notification to the fire services

A key basic fire prevention method is employeesrsquo awareness of the hazards which maycontribute to a fire and how to get out from the building safely In addition having anoutdated fire prevention plan equals to not having any It is important to ensure that fireprevention plan items are reviewed on a regular basis and practical drills are carried out toachieve the maximum results Refer to Table 7 on measures to eliminate or minimise firehazards in the workplace

Table 7 Measures to eliminate or minimise fire hazards in the workplace

Potential sources Examples of preventive measures

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Chapter 4 Workplace Safety and Health Management

4 Overview

Workplace Ssafety and Health (WSH) management programme is a systematic way ofmanaging WSH Implementing workplace safety and health programme effectively helps in

reducing the extent and severity of work-related injuries and illnesses (and thereforereducing work-injury compensation costs) and also improves employee morale andproductivity

It is good practice that employers consider developing and implementing a comprehensiveworkplace safety and health (WSH) management programme Elements in a WSHmanagement programme include

41 WSH Policy

Developing and implementing a written safety and health policy is the core to demonstratethe commitment of top management WSH policy should clearly state the following

bull

The managementrsquos commitment and approach towards providing a safe and healthywork environmentbull Organisationrsquos safety and health goals and objectivesbull Duties and responsibilities of the management and employees

42 Safe Work Procedures

Employers are encouraged to establish Safe Work Procedures (SWP) that describe howwork can be carried out safely and the types of actions to be taken in the event of anemergency (associated with the particular activity) SWP should be effectivelycommunicated to all employees during orientation of new employees and at regularintervals for existing employees

43 WSH Training

WSH training is important in providing staff with the knowledge and skills to work in a safeand healthy manner The complexity of the WSH training needs depend on the nature ofhazards size and complexity of the work activities carried out Employers are encouraged toset up a system that identifies the WSH training needs for each level of staff ie manageriallevel supervisory level and operational level in order to make the appropriate training plansEmployers should also be aware of the statutory training requirements stipulated under theFactories (Safety Training Courses) Order It is important to ensure that training conductedin-house is documented and records of attendance (eg competency certificates) areobtained if employees are sent for training conducted by external agencies

44 WSH Group Meetings

Group meetings should be conducted regularly to discuss WSH issues and to disseminaterelevant WSH information to employees including contractors accordingly The frequency ofgroup meetings can be weekly or daily which serves as an effective channel for conveyingWSH information

45 Incident Investigation and Analysis

Employers should establish and implement a system that ensures that all incidents arereported and investigated This includes accidents which cause injury or illness but near-misses ie occurrences that do not result in injury or illness as well Investigation andanalysis of each incident should aim to identify the root cause so as to prevent similaroccurrences in the future Information collected during incident investigation analysis andthe follow-up actions taken should be properly documented For accidents that are requiredto be reported to the Ministry of Manpower all relevant reports shall be documented for atleast three years(Reference WSH (Incident Reporting) Regulations 2006)

46 In-house WSH Rules and Regulations

A set of in-house written WSH rules and regulations with key legal requirements and dutiesshould be established for employees and contractors to comply Each functional departmentmay provide specific or detailed safety rules and regulations for the operational needs

47 WSH Promotion

Employers should establish promotional programmes to create WSH awareness and tobuild a strong WSH culture at the workplace The following are some promotional activitiesthat can be organisedbull Participation in WSH talks seminars and exhibitionsbull Participation in the National WSH Campaign and competitionsbull Subscription to WSH Bulletin on the WSH Council Website at wwwwshcsgbull Newsletters or in employeersquos notice board at the workplace andbull In-house poster competitions quiz competitions best WSH-conscious work team

competitions and WSH exhibitions

48 Evaluation Selection and Control of Contractors

While it is common for businesses to appoint contractors for certain jobs at their premises itis important that the works carried out by contractor do not place their own employees orother persons (eg customers) at risk For this reason it is recommended for an employerto have a system that allows an evaluation on the contractors before any work is awardedThe bizSAFE programme implemented by the WSH Council provides a yardstick forbusinesses to select contractors For more information on bizSAFE refer to the Councilrsquoswebsite at wwwwshcsg

49 WSH Inspection

An effective programme should be established to carry out periodic inspections to identifypotential hazards unsafe acts and conditions in the workplace The inspections shouldinvolve both the management and employees The outcome of the findings andrecommendations should be properly documented and implement the follow up actions

410 Maintenance Programme

An effective maintenance programme should be established for all equipment (eg cleaningand lifting equipment) and tools used This will help prevent accidents resulting from thefailure of such equipment and tools There should also be a system for employees to reportany defective or damaged tool or equipment in the course of their work

411 Hazard Identification Evaluation and Control

In Chapter Two hazard identification risk evaluation and risk controls are the three basicsteps of risk assessment Inspecting workplaces should be conducted actively so that thefocus is not only on existing hazards but also on hazards that could arise due to changes inwork conditions and processes

412 Occupational Health ProgrammesOccupational health programmes targeted at specific hazards should be established Eachprogramme should specify the objectives person-in-charge component activities andfrequency Refer to Table 8

Table 8 Examples of occupational health programmes

Examples of occupational health programmes

Hazards Programme

Excessive noise Hearing conservation programme

Chemical exposure Chemical management programme

Awkward work postures repetitive workmanual handling

Ergonomics programme

413 Emergency Preparedness

Through risk assessment results employers should recognise all the foreseeableemergency situations eg fire and medical attention Employers should then establish andimplement emergency response plans and procedures accordingly It is critical that all staff

are familiar with emergency procedures This can be achieved through periodic trainingregular drills and exercises

414 Evaluation of Programme Effectiveness amp Documentation

Proper documentation along with regular review of the programme ensures that the systemis effective and appropriate to the work conditions It is recommended for an employer toconduct reviews on the programme at least once every year Should the evaluation processindicate significant deficiencies andor deviations employer should then ensure that these

Duties of the Self-employed PersonIt is the duty of the self-employed person to take measures as far as it being reasonablypracticable to ensure the safety and health of others such as members of the public or hisown employees

Definition of ldquoReasonably PracticablerdquoThe term ldquoreasonably practicablerdquo means that the degree of risk in a particular situationcan be balanced against the time trouble cost and physical difficulty of taking measuresto avoid the risk

An action is considered to be practicable when it is capable of being done It takes intoaccountbull The severity of any injury or harm to health that may occurbull The degree of risk (or likelihood) of that injury or harm occurringbull How much is known about the hazard and the ways of eliminating reducing or

controlling itbull The availability suitability and cost of the safeguardsbull The cost of putting safeguards in place needs to be measured against the

consequences of failing to do so Whether the employer can afford to put thenecessary safeguards in place is not a consideration particularly where there isrisk of serious injury or frequent but less severe injury
