Effective management of health and safety: is vital to employee well-being has a role to play in enhancing the reputation of businesses and helping them
achieve high-performance teams is financially beneficial to business
4 C’s CompetenceControlCo-operationCommunication
Health– the protection of the bodies and minds of people from illness resulting from the materials, processes or procedures used in the workplace.
Safety– the protection of people from physical injury.
Ill health- the two words are normally used together to indicate concern for the physical and mental well-being of the individual at the place of work.
Welfare– the provision of facilities to maintain the health and well-being of individuals at the workplace. e.g. washing and sanitation arrangements, the provision of drinking water, heating, lighting, and accommodation for clothing, seating (when required by the work activity), eating and rest rooms, first aid arrangements.
Occupational or work-related ill-health – is concerned with those illnesses or physical and mental disorders that are either caused or triggered by workplace activities. The time interval between exposure and the onset of the illness may be short (e.g. asthma attacks) or long (e.g. deafness or cancer).
Environmental protection– arrangements to cover those activities in the workplace which affect the environment (in the form of flora, fauna, water, air and soil) and, possibly, the health and safety of employees and others. Eg include waste disposal and atmospheric pollution.
Hazard–is the potential of a substance, activity or process to cause harm. Hazards take many forms including, for example, chemicals, electricity and working from a ladder. A hazard can be ranked relative to other hazards or to a possible level of danger.
Risk - likelihood of a substance, activity or process to cause harm. A risk can be reduced and the hazard controlled by good management.
Hazard and a risk – the two terms are often confused and activities such as construction work are called high risk when they are high hazard. Although the hazard will continue to be high, the risks will be reduced as controls are implemented. The level of risk remaining when controls have been adopted is known as the residual risk. There should only be high residual risk where there is poor health and safety management and inadequate control measures.

Insured Direct costs: Claims on employers and public liability insurance Damage to buildings, equipment, vehicles Absence from employees
Uninsured Direct costs: Fines resulting from prosecution by the enforcement authority Sick pay Some damage to the product , equipment, vehicles or process (not directly
associated with accident Increases in insurance premium Any compensation not covered by insurance Legal representation following a compensation claim
Insured Indirect costs: A cumulative business loss Product or process liability claims Recruitment or replacement staff
Uninsured Direct costs: Loss of goodwill and a poor corporate image Accident investigation time Production delays Extra overtime payments Recruitment and training replacement staff First aid-provision and training Lower employee morale possibly leading to reduced productivity
Employers Liability Compulsory Insurance (Act) legal requirement (£2500/day fine) ensures that any employee who successfully sues his employer following an accident, is
assured of receiving a compensation irrespective of financial position of the employer min one copy must be displayed copies to be kept for 40 years
LAW
by Anna-Barbara Patallas for HSfB
Criminal law is enforced by several different Government Agencies who may prosecute individuals
for contravening criminal laws. An individual who breaks criminal law is deemed to have committed an offence or crime
and, if he is prosecuted, the court will determine whether he is guilty or not the court could sentence him to a fi ne or imprisonment The Health and Safety at Work Act (enforced by the Health and Safety Executive or
Local Authority Environmental Health Officers) Road Traffic Acts The prosecution in a criminal case has to prove the guilt of the accused beyond reason-
able doubt. While this obligation is not totally removed in health and safety cases, section 40 of the Health and Safety at Work Act 1974 transferred, where there is a duty to do something ‘so far as is reasonably practicable ’or ‘so far as is practicable’ or ‘use the best practicable means’, the onus of proof to the accused to show that there was no better way to discharge his duty under the Act. However, when this burden of proof is placed on the accused, they need only satisfy the court on the balance of probabilities that what they are trying to prove has been done.
Magistrates Courts brought before the court by enforcement officers tried by a bench of three lay magistrates (members of public) or a single district judge maximum fine of £5000 (for employees) to £20 000 for employers or for those who
ignore prohibition notices imprison for up to six months for breaches of enforcement notices
Crown Court Passed from Magistrates Courts Cases are heard by a judge (sometimes him alone) and jury unlimited fine and up to two years imprisonment for breaches of enforcement notices hears appeals from the Magistrates CourtCivil law
by Anna-Barbara Patallas for HSfB
disputes between individuals or individuals and companies An individual sues another individual or company to address a civil wrong or tort the level of proof required is based on the ‘balance of probability’, which is a lower level
of certainty than that of ‘beyond reasonable doubt’ required by the criminal court
County Court deals with minor cases compensation claims of up to £50 000 if the High Court agrees normally heard by a judge sitting alone For personal injury claims of less than £5000
High Court before a judge only compensation claims in excess of £50 000 acts as an appeal court for the County Court appeals from the High Court are made to the Court of Appeal fine based on company turnover and ability to pay
Supreme Court Independent institution 12 judges Final court of appeal
Employment Tribunals deal with employment and conditions of service issues, such as unfair dismissal usually three members who sit on a Tribunal (often not legally qualified)
Sources of law
Negligence - The only tort (civil wrong) of real significance in health and safety; it is the lack of reasonable care or conduct which results in the injury, damage (or financial loss) of or to another.It is a common law tortSummarised as Careless Conduct/Breach of Duty of Care
An employee, who is suing his employer for negligence, needs to establish the following three criteria:
by Anna-Barbara Patallas for HSfB
a duty was owed to him by his employer since the incident took place during the course of his employment
there was a breach of that duty because the event was foreseeable and all reasonable precautions had not been taken
the breach resulted in the specific injury, disease, damage and/or loss suffered.
Defence: contributory negligence volenti non fit injuira (risk was willingly accepted) vicarious liability (where the defendant is an employee who was acting in the course of
his employment during the alleged incident, the defence of the action is transferred to his employer)
Any negligence claim must be made within 3 years (Limitations Act)
Tests to be satisfied: That a duty of care was owedThat there was a breach of that dutyThat the breach led directly to the harm

HEALTH AND SAFETY AT WORK ETC ACT 1974
Part 1 relates to HW&W at the workplacePart 2 relates to EMASPart 3 relates to Building RegsPart 4 contains misc. & general provisions
PRACTICABLE –capable of being carried out or feasible (given current knowledge, finance, information etc.)
REASONABLY PRACTICABLE – must be technically possible, and the risk assessed against the cost. Where cost is disproportionately high, can be deemed not to be reasonably practical.
H&S Inspectorate powers include: Investigation, Advisory, Enforcement (Imp. Not, Pro. Not, Seize/destroy substances/articles, Prosecute)
DUTIES OF CARE: provide a safe place of work, including access and egress provide safe plant and equipment provide a safe system of work provide safe and competent fellow employees provide adequate levels of supervision, information, instruction and training.
LEVELS OF DUTY:
Absolute duty occurs when the risk of injury is so high that injury is inevitable unless safety
precautions are taken ‘must’ and ‘shall’ it may still be defended using, for example, the argument that ‘all reasonable
precautions and all due diligence’ were taken (only The Electricity at Work Regs and The Control of Substances Hazardous to Health Regs)
Practicable Employer must ensure, so far as is practicable, that any control measure is maintained
in an efficient state (if the duty is technically possible or feasible then it must be done irrespective of any difficulty, inconvenience or cost)
Reasonably practicable if the risk of injury is very small compared to the cost, time and effort required to reduce
the risk , then no action is necessary It is important to note that money, time and trouble must ‘grossly outweigh’ not
balance the risk clearly needs a risk assessment ‘suitable and sufficient’
by Anna-Barbara Patallas for HSfB
Regulations Enabling Act (allows the Secretary of State to make further laws (known as regulations)
without the need to pass another Act of Parliament) It is a criminal offence to breach a regulation and any breaches may result in
enforcement action aim to help employers to set goals, but leave them free to decide how to control
hazards and risks which they identify
ACOP produced for most sets of regulations by the HSC attempts to give more details on the requirements of the regulations quasi-legal (Highway Code to the Road Traffic Acts)
Codes of Practice generally are only directly legally binding if: the regulations or Act indicates that they are, for example, the Safety Signs and Signals
Regulations Schedule 2 specify British Standard Codes of practice for alternative hand signals; or
they are referred to in an Enforcement Notice
Guidance no formal legal standing legal and best practice issued by the HSC and/or the HSE to cover the technical aspects of health and safety
regulations

Enforcement notices
by Anna-Barbara Patallas for HSfB
Improvement notice identifies a specific breach of the law and specifies a date by which the situation is to be remedied An appeal must be made to the Employment Tribunal within 21 days. The notice is then
suspended until the appeal is either heard or withdrawn
Prohibition notice used to halt an activity which the inspector feels could lead to a serious personal injury identify which legal requirement is being or is likely to be contravened takes effect as soon as it is issued an appeal may be made to the Employment Tribunal but, in this case, the notice
remains in place during the appeal processThere are two forms of prohibition notice:➤an immediate prohibition notice – this stops the work activity immediately until the specified risk is reduced➤a deferred prohibition notice – this stops the work activity within a specified time limit.
Prosecution
Breaches of HSWA can lead to:
Max. £20K fine (max. £5K fine for employee) and/or 6 months imprisonment (Summary Conviction – Magistrates Court)
Unlimited fine and/or 2 years imprisonment & can disqualify director up to 15 years (Indictable Offence –Crown Court)
Civil Law – Prosecution on Balance of Probabilities (Civil Law established by case precedence)
Criminal Law – Prosecution beyond all reasonable doubt (Statute & legislation)

Employers duties➤undertake suitable and sufficient written risk assessments when there are 5 or more employees➤put in place effective arrangements for the planning, organization, control, monitoring and review of health and safety measures in the workplace (including health surveillance). Such arrangements should be recorded if there are more than four employees➤employ (to be preferred) or contract competent per-sons to help them comply with health and safety duties➤develop suitable emergency procedures. Ensure that employees and others are aware of these procedures and can apply them➤provide health and safety information to employees and others, such as other employers, the self-employed and their employees who are sharing the same workplace and parents of child employees or those on work experience➤co-operate in health and safety matters with other employers who share the same workplace➤provide employees with adequate and relevant health and safety training➤provide temporary workers and their contract agency with appropriate health and safety information➤protect new and expectant mothers and young per-sons from particular risks➤under certain circumstances, as outlined in Regulation 6, provide health surveillance for employees. The information that should be supplied by employers under the regulations is:➤risks identified by any risk assessments including those notified to him by other employers sharing the same workplace➤the preventative and protective measures that are in place➤the emergency arrangements and procedures and the names of those responsible for the implementation of the procedures.
Finally, it is important to note that the regulations outline the principles of prevention which employers and the self-employed need to apply so that health and safety risks are addressed and controlled. These principles are discussed in detail in Chapter 6.
Employees duties➤use any equipment or substance in accordance with any training or instruction given by the employer➤report to the employer any serious or imminent danger➤report any shortcomings in the employer’s protective health and safety arrangements.

RISK ASSESSMENT
any risk assessment shall be reviewed if there is reason to suspect that it is no longer valid or if a significant change has taken place;
where there are more than four employees, the significant findings of the assessment shall be recorded and
any specially at risk group of employees identified
A suitable and suf fi cient risk assessment should: identify the signifi cant risks and ignore the trivial ones; identify and prioritize the measures required to comply with any relevant statutory
provisions; remain appropriate to the nature of the work and valid over a reasonable period of time Identify the risk arising from or in connection with the work. The level of detail should
be proportionate to the risk
1 serious or disabling injuries10 minor injuries (first aid injury)30 damage accidents600 near miss accidents
Health risks fall into the following four categories: chemical (e.g. paint solvents, exhaust fumes) biological (e.g. bacteria, pathogens) physical (e.g. noise, vibrations) ergonomic psychological (e.g. occupational stress)
Possible health effects of occupational ill-health acute (occur soon after the exposure and are often of short duration) chronic (health effects develop with time. It may take several years for the associated
disease to develop and the effects maybe slight (mild asthma) or severe (cancer))
Risk Assessment (5 Steps)
1. Identify Hazards2. Identify Persons Exposed (particular attention to high risk groups – young persons, pregnant workers, disabled)3. Evaluate Risks (Consider likelihood and severity) & Controls 4. Record the findings5. Review and Revise
During most risk assessment it will be noted that some of the risks posed by the hazard have already been addressed or controlled. The purpose of the risk assessment, therefore, is to reduce the remaining risk. This is called the residual risk.

PPE
SAFE SYSTEMS OF WORK
The system of work describes the safe method of performing the job activity.It is a defined method of doing a job in safe way. It takes account of all foreseeable hazards to H&S and seeks to eliminate or minimize these. formal and documented May be verbal
Effective safe system: Based on looking at the job as whole Starts from analysis of all foreseeable hazards Brings together all the necessary precautions incl. design, training, monitoring PPE
Essential features: Sequence of operations Equipment, plant Chemicals and other substances People doing the work Foreseeable hazards Practical precautions Training needs Monitoring systems
Factors to consider:
by Anna-Barbara Patallas for HSfB
Types of risks Magnitude of the risk Complexity of operation Past accident Requirement and recommendations of the H& S authorities Document type of needed Resources required
PERMITS TO WORK
It is a specialized type of safe system of work for ensuring that potentially very dangerous work (e.g. entry into process plant and other confined spaces) is done safely.The permit to work procedure is a specialized type of safe system of work under which certain categories of high risk-potential work may only be done with the specific permission of an authorized manager. This permission (in the form of the permit to work) will only be given if the laid-down precautions are in force and have been checked.
Permit systems must adhere to the following eight principles:1. wherever possible, and especially with routine jobs, hazards should be eliminated so that the work can be done safely without requiring a permit to work2. although the Site Manager may delegate the responsibility for the operation of the permit system, the overall responsibility for ensuring safe operation rests with him/her3. the permit must be recognized as the master instruction which, until it is cancelled, overrides all other instructions4. the permit applies to everyone on site, including contractors5. information given in a permit must be detailed and accurate. It must state:(a) which plant/equipment has been made safe and the steps by which this has been achieved(b) what work may be done(c) the time at which the permit comes into effect6. the permit remains in force until the work has been completed and the permit is cancelled by the person who issued it, or by the person nominated by management to take over the responsibility (e.g. at the end of a shift or during absence)7. no work other than that specified is authorized. If it is found that the planned work has to be changed, the existing permit should be cancelled and a new one issued8. responsibility for the plant must be clearly defined at all stages

Stages are: 1. Select the job/task to be reviewed2. Record – Identify and record the sequence of steps and/or components in the process3. Examine each component part of the job to identify the hazards/risks4. Develop control measures5. Install SSW/Control measures6. Maintain. Carry out regular reviews.

by Anna-Barbara Patallas for HSfB
the monitoring of risk assessments or accident/ incident investigations indicate that the health and safety policy is no longer totally effective
enforcement action has been taken by the HSE or Local Authority a sufficient period of time has elapsed since the previous review. A positive promotion
of health and safety performance will achieve far more than simply prevent accidents and ill-health.
2. Organising – structures to assist in: - Control- Co-operation- Communication- Co-ordination- Competence
3. Planning and Implementation – establish, operate and maintain systems that: - Identify objectives and targets- Set performance standards- Consider and control risks- Document performance- React to change- Sustain positive safety culture
4. Monitoring – Active and Reactive systems:* Active: Measuring achievements against specified standards before things go wrong. Ensures controls are working correctly. Safety Management Systems Audit (major exercise) Safety Survey (detailed assessment of one aspect of organization) Safety Inspection (formal assessment of workplace safety and identification of
hazardous conditions and practices for remedial actions) Safety tour (addresses the people aspects of workplace safety, and by discussions with a
range of staff; establishes their familiarity with safety procedures) Safety Sampling (focuses on one area/subject at the time - 30min inspection. Inspection
team carries out sampling at the same time each day or week in the specified period
* Reactive: Collection of information about failures. Involves learning from mistakes.After things go wrong, involves looking at historical events to learn from mistakes and see what can be put right to prevent a recurrence. The UK HSE’s experience is that organizations find health and safety performance measurement a difficult subject. They struggle to develop health and safety performance measures which are not based solely on injury and ill-health statistics.
Inspection – looks at physical conditions
Inspection checklist: Premises (work at height, access, welfare, fire precautions) Plant & substance (work equipment, vehicles, hazardous substances) Procedures (RAs, safe systems of work, permits to work, notices, signs)
by Anna-Barbara Patallas for HSfB
People (training, health surveillance, violence)
5. Review and Audit – Ensures policy is being carried out and is having the desired effect.
Audit – inspection or other monitoring activity (gathering info & making informed judgements); looks at systems and the way they function in practice

Non-mechanical machinery hazards➤access: slips, trips and falls; falling and moving objects; obstructions and projections➤lifting and handling➤electricity (including static electricity): shock, burns➤fire and explosion➤noise and vibration➤pressure and vacuum➤high/low temperature➤inhalation of dust/fume/mist➤suffocation➤radiation: ionising and non-ionising➤biological: viral or bacterial➤physiological effects (e.g. Musculoskeletal disorders)➤psycho-physiological effects (e.g. mental overload or underload)➤human errors➤hazards from the environment where the machine is used (e.g. temperature, wind, snow, lightning)In many cases it will be practicable to install safe guards which protect the operator from both mechanical and non-mechanical hazards. For example, a guard may prevent access to hot or electrically live parts as well as to moving ones. The use of guards which reduce noise levels at the same time is also common. As a matter of policy machinery hazards should be dealt with in this integrated way instead of dealing with each hazard in isolation.

ACCIDENTS
Accident– ‘any unplanned event that results in injury or ill health of people, or damage or loss to property, plant, materials or the environment or a loss of a business opportunity’. Other authorities define an accident more narrowly by excluding events that do not involve injury or ill-health.
Near miss– is any incident that could have resulted in an accident. For every 10 ‘near miss’ events at a particular location in the work-place, a minor accident will occur.
Dangerous occurrence– is a ‘near miss’ which could have led to serious injury or loss of life. Dangerous

occurrences are defined in the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (often known as RIDDOR) and are always reportable to the Enforcement Authorities. Examples include the collapse of a scaffold or a crane or the failure of any passenger carrying equipment. One of a number of specific, reportable adverse events
Immediate cause –the most obvious reason why an adverse even happens, e.g. guard is missing. There may be several immediate causes in any one adverse event.Personal Factors: Behaviour Suitability of people doing the work Training and competence
Task factors: Workplace conditions and precautions or controls Method of work at the time Ergonomic factor Normal working practice
by Anna-Barbara Patallas for HSfB
Root cause – initiating event or failing from which all other causes or failings spring. Usually management, planning or organizational failings;
Quality of H&S policy Quality of consultation & cooperation with employees Quality of communication Deficiencies in RA, control systems Lacks in monitoring Quality & frequency of reviews an audits
Analysis: (higher level investigation) Tree of causes
Analysis: (minimal & low level investigation) What caused this practice to occur? – until u get to root causes 5 why’s (Simple, effective, comprehensive, flexible, engaging, inexpensive)
Underlying cause – less obvious system or organizational reason for an adverse event happening e.g. production pressures are too great;
Pre-start-up m/c checks were not made by supervisors Hazard not considered in RA No MS Pressure of production more important Employee under pressure Any similar incidents in the past? Was there adequate supervision?
Which incidents/accidents should be investigated - In fact the main determinant is the potential of the accident to cause harm rather than the actual harm resulting.
Accident Investigation: In a minimal level investigation, the relevant supervisor will look into the circumstances
of the accident/ incident and try to learn any lessons which will prevent future incidents A low level investigation will involve a short investigation by the relevant supervisor or
line manager into the circumstances and immediate underlying and root causes of the accident/incident, to try to prevent a recurrence and to learn any general lessons
A medium level investigation will involve a more detailed investigation by the relevant supervisor or line manager, the health and safety adviser and employee representatives and will look for the immediate, underlying and root causes
A high level investigation will involve a team-based investigation, involving supervisors or line managers, health and safety advisers and employee representatives. It will be carried out under the supervision of senior management or directors and will look for the immediate, underlying and root causes.
Four basic elements to a sound investigation:
by Anna-Barbara Patallas for HSfB
1. collect facts about what has occurred2. assemble and analyse the information obtained3. compare the information with acceptable industry and company standards and legal requirements to draw conclusions4. implement the findings and monitor progress
Phases: Direct observation Documents Interviews

ELECTRICITY
ELECTRICITY AT WORK REGULATIONS 1989
by Anna-Barbara Patallas for HSfB
It is a flow or movement of electrons through a substance which allows the transfer of electrical energy from one position to another.
Mains voltage (220V/240V) – electrical shock/electric burns / electrical fires & explosions
V = I x R (volts)
v-voltage / I-current / r-resistance / P- electrical power
P=V x I (watts)
Conductor – almost always metal (copper /water)Superconductor-very low resistance to electricity at low temperaturesInsulators- very poor conductors (rubber/timber/plastics)Circuit – electrical equipment components and power supply are joined togetherShort circuit – if circuit is broken and producing a fault so that the current flows directly to earth rather than to equipmentEarthing-if there is a fault (break in the circuit) the current will return directly to earth.Low voltage- no more than 600Vac between conductors and earth
No more than 1000Vac between phases
High voltage- more than 600Vac between conductors and earthmore than 1000Vac between phases
Mains voltage-domestic premises 220/240Vac at 50 cycles /sIsolation- cutting off the electrical supply from all or a discrete section of the installation by separating the installation or section from every source of electrical energy.
Hazards: el. shock – convulsive reaction by the human body to the flow of electric current
through it (low/high voltages and lightning); cardiac arest el. burns el. fires & explosions overheating cables/lack of care/loose cable connections
/ventilation/sparks/static electrical charges/use of el equipment in flammable atmospheres)
arcing (1.person who is standing on earth too close to a high voltage conductor may suffer from flash burns as a result of arc formation) – temporary blindness by burning the retina) reduced by insulation of live conductors; 2.strong electromagn fields induce surfaces charges on people. If these charges accumulate, skin sensation is affected and spark discharges to earth may cause localized pain/bruising)
secondary hazards
Electric shock / burns – treatment: Raise the alarm Call for help (first aider) Switch off the power / position of emergency isolation Call for ambulance
by Anna-Barbara Patallas for HSfB
If it’s not possible to switch the power off then push/pull the person away from the conductor using a good isolator (wooden). Stand on dry/insulating material (wood/rubber)
If is breathing than place him in recovery position- mouth can drain away / airway open If is not breathing apply mouth-to-mouth resuscitation and chest compressions if no
pulse Then look above Burns-put sterile dressing and secure with bandage. Loose skin/blisters-do not touch If the person regains consciousness, treat for normal shock Remain with person until taken to hospital
If electrocuted by high voltage - call police / electric supplier & keep 18m distance
Static electricity – produced by the build up of electrons on weak electrical conductors or insulating materials (gaseous/liquid/solid) by quick separation of highly insulated materials by friction or by transfer from one highly charges material to another. (incl. flammable liquids/powders/plastic films)Plastics have high resistance – retain static charges for longer.E.g closing the door with a metallic handle.
Portable electrical equipment – not part of a fixed installation but may be connected to a fixed installation by means of a flexible cable and either a socket and plug or a spur box or similar means. May be hand held or hand-operated. Extension leads/plugs/sockets to be used with this equipment is also classed as PEE.Portable means portable & transportable.
Secondary hazards: Working with not maintained electrical equipment Using el equipment in adverse or hazardous environments Working on mains electricity supplies Contact with underground cables during excavation work Contact with live overhead power lines
Control measures:Permit to workSelection of suitable equipmentUse of protective systemsInspection and maintenance strategies
Protective systems:
Fuse-protection against faults & continuous marginal current overloads(Its thin strip of conducting wire which melts when excess of the rated current passes through it breaking the circuit.)Circuit breaker throws a switch off when excess current passes and it’s similar to the fuse.
by Anna-Barbara Patallas for HSfB
Fuse is to protect equipment and /or installation from overheating and becoming a fire hazard. Its takes long time to cut the current flow- not a protection against electric shock.
Insulation – to protect people from electric shock, short circuiting of live conductors and danger of fire and explosions.Covering the conductor with insulating material. + enclosure
Isolation-circuit is made dead and cannot be accidentally re-energized. Barrier between equipment and electrical supply. It will ensure safety during work process.Isolators always locked off when work is to be done on electrical equipment.
Reduced low-voltage systems – severe working conditions (wet weather/heavy usage)100V available – transformer - 50V
Residual current devices (RCD) - if equipment operates at mains voltage. Monitors and compares current flowing in the live and neutral conductors supplying the equipment. Very sensitive. Very quick – electric shock.
Double insulation – to remove need for earthing in portable power tools. Two independent layers of insulation over the live conductors. Each must be good on its own.
Maintenance: Cleanliness of insulator and conductor surfaces Mech and electr integrity of all joints and connections Integrity of mechanical mechanism, such as switches and relays Calibration, condition and operation of all protection equipment (RCDs, circuit breakers) Isolators fitted with lockable mechanism –allow fuse withdrawal wherever isolators are
not fitted. Working on more than 110V not permitted unless necessary System of visual inspection Inspected & tested regularly
Portable Electrical Appliance Testing: User Check Formal Visual Inspection Combined Inspection and Check
Correct polarity Correct fuses are being used Cables and cores are effectively terminated Equipment suitable for environment
PATAdvantages: Early recognition Incorrect fuses Reduction in accidents Monitoring misuse of appliances Equipment selection procedure checkable
by Anna-Barbara Patallas for HSfB
Increased awareness Regular maintenance
Disadvantages: Too often- cost Unauthorised equipment (kettles) never checked Do not know the meaning of test results No competence of the tester equipment not calibrated properly

FIRE
THE REGULATORY REFORM (FIRE SAFETY) ORDER (RRFSO)
Fire precautions: Reduction of fire risks and fire spread Means of escape Keeping them available to use Fire-fighting Fire detection and warning Action to be taken in event of a fire Instruction & training + process related fire precautions
Responsible person: employer/owner/other who has control over premises
Responsible person duties: Do RAs Review RAs Record findings Apply principals of preventions Set out fire appropriate safety arrangements for Planning Organization Control
Monitoring Review Eliminate or reduce risks Must ensure that following are provided (FFE/detectors/alarms/trained & competent
person/ contact with external services) Emergency routes nad procedures Safety assistance Provision of information Capabilities/training/cooperation
Emergency procedures / emergency routes and services / fire detection and fire fightning
Fire Triangle
Fuel + Ignition source + Oxygen
Fuel: Solids/liquids/gasesIgnition source: naked flames/external sparks/internal sparking/hot surfaces/static electricityOxygen: air (enhanced by wind/ventilation)
Fire Classification:
by Anna-Barbara Patallas for HSfB
Class A – solid materials – waterClass B – liquids / liquefied solids
B1-liquids soluble in water (methanol)-dry powder/CO2/water sprayB2-liquids not soluble in water (petrol/oil) - foam / dry powder/CO2/light water
Class C –gasses (natural gas/liquefied gas – butane /propane) – foam / dry powderClass D – metals (aluminium / magnesium) – special dry powderClass F – high-temperature cooking oils/fatsElectrical fires – co2/dry powder
Heat Transmission & Fire spread:
Convection – hot air becomes less dense & rises, drawing in cold new air to fuel the fire with more oxygen. Heat is transmitted upwards at sufficient intensity to ignite combustible materials in the path of the very hot products of combustion & flames.
Conduction – transmission f heat through a material with sufficient intensity to melt or destroy the material & ignite combustible materials which come into contact or close to a hot section. (copper/steel/aluminium)
Radiation – often in a fire, direct transmission of heat through the emission of heat waves from a surface can be so intense that adjacent materials are heated sufficiently to ignite.
Direct burning - effect of combustible materials catching fire through direct contact with flames which causes fire to spread.
Fire RA: Identify fire hazards Id combustibles Id source of heat Id unsafe act Id unsafe conditions Id persons at risk Evaluate & reduce the risk Monitor & review
Good housekeeping / storage / control of flammable & combustible materials / control of ignition sources / systems of work
HEALTH AND SAFETY (SAFETY SIGNS AND SIGNALS) REGULATIONS 1996
by Anna-Barbara Patallas for HSfB
Safety sign-sign referring to a specific object activity or situation and providing info or instruction about h&s at work by means of a signboard/safety colour/illuminated sign/ a verbal communication/hand signal.

Explosive atmosphere – accumulation of gas/mist/dust/vapour mixed with air which has the potential to catch fire or explode.
Substitution / Control measure / mitigation measures / storage / flammable gasses / aerosols
Fire protection of buildings: Leave quickly & safely Must remain standing as long as possible Spread of fire & smoke must be reduced Fire loading Surface Fire resistance of structural elements Insulating materials Fire compartmentation
Ways of extinguishing fires: Cooling - reducing the ignition temp by tackling the heat out of the fire- using water Smothering- limit the oxygen available by smothering and preventing the mixture of
oxygen and flammable vapour – foam / fire blanket Starving – limiting the fuel supply by removing source of fuel by switching off el power Chemical reaction – by interrupting the chain of combustion and combining the
hydrogen atoms with chlorine atoms in the hydrocarbon chain (halon extinguisher)
CHEMICALS
Forms of chemical agents:
Dusts – solid particles slightly heavier than air but suspended in it for a period of time.Created by chemical/mechanical processes.
Respirable dust – fine dust penetrating into the lungs or bloodstream.Inhalable dusts – any dust that can enter the nose and mouth during breathing
Gases – substances present at a temperature above their boiling point (carbon monoxide)Vaporous – substances which are at or very close to their boiling temperatures. Gaseous in form. (many solvents)Liquids-substances that normally exist at a temperature between freezing (solid) and boiling (vaporous and gases) points. = fluids.Mists – similar to vaporous – they exist at or near their boiling temperature but are closer to the liquid phase. Spraying process.Fume – collection of very small metallic particles which have condensed for the gaseous state. Welding process.
by Anna-Barbara Patallas for HSfB
Forms of biological agents:
Fungi – v.small organism, sometimes consist of a single cell and can appear as plantikle.

Strong acids/alkaidsHarmful –if swallowed/inhaled/penetrates the skin, may pose limited health risks. Chemical cleansers.Toxic – impede or prevent the function of one or more organs within the body such as kidney/liver/heart. Poisonous (lead/mercury/alcohol)Carcinogenic-suspected of promoting abnormal development of body cells to become cancers. (asbestos/hardwood dust)Mutagenic – damage genetic material within cells, causing abnormal changes that can be passed by generations
Effects:
Acute – effects are of short duration and appear rapidly, usually after single or short-term exposure; asthma attack/sneeze/CO2Chronic – develop over a period of time which may extend to years. From prolonged or repeated exposures; Asbestosis/mental disease;
Routes of entry:
Inhalation – breathing in the substance with normal air intake. Lungs – blood stream-organsAbsorption through the skin – substance comes into contact with the skin and enters through pores or wound. Tetanus/Benzene/tolueneIngestion – through the mouth and swallowed into the stomach and the digestive system. Air borne dust / poor personal hygiene.Injection- shooting high pressure air at the skin - pressure systemsExchange of body fluids – HIV
by Anna-Barbara Patallas for HSfB
Respiratory systemLungs and associated organs;Fibrosis – respirable dust punctures alveoli walls. The puncture heals producing scar tissues which are less flexible than original walls. That may lead to...
Acute - Bronchitis/AsthmaChronic – fibrosis / asthma – hardwood dustAsphyxiation – lack of oxygen (MIG in confined SPACES)
Nervous SystemBrain, spinal cord, nerves throughout the body;Neurotoxins (organic solvents & heavy metals-mercury) – can reduce effectiveness of nervous system and lead to changes in mental ability (loss of memory), epilepsy and narcosis (loss of consciousness).
Cardiovascular SystemBlood System (heart) – oxygen transport/attack foreign organisms/aid healing of damaged tissueSubstances: Benzene (reduce number of blood cells)Carbon monoxide (prevents red cells from absorbing sufficient oxygen) – headaches/ unconsciousness/death
Urinary systemExtracts waste and other products from blood. Liver (remove toxins from blood/maintains levels of blood sugars) & Kidney (filter waste products from blood as urine/regulate blood pressure / produce hormones for making red blood cells).Substances can cause liver to be too active or inactive (xylene) / lead to liver enlargement (cirrhosis caused by alcohol) / liver cancer (vinyl chloride).Kidney – heavy metals (cadmium/lead)/ organic solvents can restricts operation leading to failure.
SkinHolds body together / defence against infection / regulates body temp /sensing mechanismDermatitis (reportable) – blisters – caused by various chemicals

Material safety data sheet: Name, chemical composition, nature of a health hazard ,relevant exposure standard, recommended exposure control measures, ppe, first aid, fire-fighting measures, handling, storage , transport, disposal, manufacturer name and address, publications, industry information
1. Stain Tube Detector Use direct reading glass indicator tubes filled with chemical crystals which change colour when a hazardous substance passes through them.Advantages: quick, simple, inexpensiveDisadvantages: can’t be use for concentrations of dust or fume, accuracy will not be ok when particular contaminants are present, tubes fragile, limited shelf live, tube to be used once
2. Passive Sampling Measures over a full working period by worker wearing a badge with absorbing material.
3. Sampling pumps and heads To measure gasses and dust. Worker wears collection head as a badge and a battery operated pump on his back at waist level. Pump draws air continuously through a filter, fitted in the head, which will absorb the contaminant gas or trap hazardous dust particles.Weight change is measured/chemical analysis/microscope analysis.
4. Direct reading instruments Analysers to be used by experience operatives. Infrared gas analysers. Very accurate. Very expensive.

HEALTH AND SAFETY (FIRST AID) REGUALTIONS 1982 AS AMENDED IN 2002
by Anna-Barbara Patallas for HSfB
REGISTRATION, EVALUATION AND AUTHORIZATION OF CHEMICALS REGUALTIONS REACH
Chemical safety regime that restricts high risk substances and require safer substitutes. (glues, paints, detergents, plastics)
Engineering Controls:
Local Exhaust Ventilation
Removes the hazardous gas/vapour/fume at its source before it can contaminate the surrounding atmosphere. (welding)
Collection hood – hood placed over workstationVentilation ducting – conduit for the contaminated air; transports it to the filterFilter/air cleaning device – between hood and fan; removes contaminant from the air streamFan – moves the air through the system; correct type/size to be used.Exhaust duct – exhaust the air to the outside of the building; checked reguraly;
Checked every 14 months.
Dilution (General) Ventilation
Uses natural ventilation (windows) or fan-assisted forced ventilation. It works by removing the contaminant or reducing the concentration.
Controls: Reduce time exposure Reduce number of workers Eating etc prohibited Special rules
by Anna-Barbara Patallas for HSfB
PPE: Filtering mask (8/10hrs only) Half-mask respirator (rubber/plastic – covers nose & mouth) Full-face mask respirator (covers eyes & visor) Powered respirator (battery fan delivers air through a filter) Self-contained breathing apparatus (compressed air cylinder) Fresh air hose apparatus (sealed face mask, air from uncontaminated source) Compressed air line apparatus (from compressed air line) Gloves (PVC/nitrile/neoprene) Arm shields Spectacles (safety glasses) Goggles Face visors Clothing Footwear

OCCUPATIONAL HEALTH
CONTROL OF NOISE AT WORK REGULATIONS 2005
Assess noise levels & keep records (make sure legal limits are not exceeded)Reduce the riskInformation & trainingProvide PPEHealth surveillanceNoise data for manufactured equipment
Sound pressure wave passes into and through the outer ear and strikes the eardrum causing it to vibrate. This causes the proportional movement of 3 interconnected small bones in the middle ear – passing the sound to the cochlea in the inner ear. There sound is transmitted to a fluid causing it to vibrate. Motion of the fluid induces a membrane to vibrate which causes hair cells (attached to membrane) to bend. This causes a minute electrical impulse to be transmitted to the brain along auditory nerve.
Acute Effects: Temporary threshold shift – short excessive noise; slight deafness; reversible; Tinnitus – ringing in the ears caused by intense & sustained high noise level; up to
24hrs; Acute acoustic trauma – vary loud noise;
Chronic effects: Noise-induced hearing loss – from permanent damage to the hair cells; ability is not lost
completely, affects hearing of the speech; Permanent threshold shift – from prolonged exposure to the loud noise; 4000Hz;
difficulty in hearing – some female voices; Tinnitus –same but permanent;
Each 3dB increase is doubling sound intensity.
Scales:A – sound pressure levels (SPLs) up to 55dBB- 55-85dBC- above 85dB
Sound level meter: Integrated - integrate the reading; provide an average over a time period; continuous
equivalent noise level (Leq) – normally over 8hrs; Direct reading – cheaper; if noise levels are continuous at a near constant value
Daily personal exposure Level (Lepd) - over 8hrs; Peak sound pressure (Pascal) (Pa) - highest noise level reached by the sound
by Anna-Barbara Patallas for HSfB
Exposure Action level values – level of noise at which certain action must be takenExposure Limit value – level of noise at the ear above which an employee must not be exposed
Daily/weekly personal exposure action level 80dB(A) – 85dB(A) (87dB(A) – exposure limit value)A peak sound pressure 135dB(C) -137dB(A) – exposure limit value 149dB(C)
Noise Assessment: Details of noise meter used- date of calibration Number of employees using the machine Indications of the condition of the m/c & maintenance schedule Work being done on m/c at the time Schematic plan of workplace Other noise sources Recommendations Inform/instruct/train PPE
Reduce time exposure – Hierarchy techniques: Reduction noise at source
*Change the process or equipment*Change speed of m/c*Improve the maintenance regime
Reduce of noise levels received by employee (attenuation)*Orientation/re-location of equipment*Enclosure (with sound-insulating material)*Screens/absorption walls (where sound is reflected from walls)*Damping (insulating floor mounting to reduce/remove transmission of noise/ vibrations)*Lagging (insulation of pipes / fluid containers)*Silencers (fitted to engines which are exhausting gases to atmosphere)*Isolation of workers (sound proof workrooms)
PPE*Earplugs*Ear defenders (earmuffs)

Confined space – means any place incl. any chamber/tank /vat/silo/pit/trench/pipe/sewer/Flue/well or similar space in which by virtue of its enclosed nature there arises a reasonably foreseeable specified risk.
Specified risk – risk to any person at work of: Serious injury arising from fire/explosion Loss of consciousness arising from an increase in body temp Loss of consciousness or asphyxiation arising from gas/fume/vapour/lack of oxygen Drowning arising from increase in the level of liquid Asphyxiation arising from a free-flowing solid or because of entrapment by it
Only enter if it’s not reasonably practicable to do it without entry.Adhere to safe system of work unless in emergency.
Risk Assessment: General conditions (content of space/residues left/contamination/oxygen deficiency
and enrichment/physical dimensions) Hazards arising directly from the work being undertaken (use of cleaning
chemicals/sources of ignition for flammable dusts/gases/vapours etc.) Need to isolate confined space from outside services or substances inside
