UIK Chemicals Management Emergency Procedure

UIK 4 Chemicals Management Emergency Procedure

1. Introduction

1.1 Background

In this Specification chemicals are defined as all liquid, gaseous and solid substances, which

are used in all UIK laboratories both interior and coast. All laboratory chemicals are

registered and provided with SHOC cards, MSDS or in case of registered lab chemicals

covered by label and laboratory chemical safety book.

Chemical emergencies involving hazardous materials in laboratories can be risk to human

health or the environment. Possible emergencies include:

fires and explosions

chemical spills or leaks

releases of airborne hazardous chemicals outside the fume hood

1.2 Purpose

The purpose of this manual is to describe practices and procedures of spill control which will

be applied and followed by UIK laboratories staffs and third party staffs working with

hazardous chemicals in PDO operating and stand alone laboratories. In order to protect them

from potential health and physical hazards presented by chemicals used in the workplace,

and to keep chemical exposures below specified limits.

2. Chemicals Spill Guideline

2.2 Roles and Responsibilities

The range and quantity of hazardous substances used in laboratories require preplanning to

respond safely to chemical spills. Therefore, Laboratory Supervisors should ensure that

emergency preparedness measures appropriate to the hazards in the laboratory are put into

place and that lab workers are familiar with the locations and use of those measures. Minor

chemical spill is one that the laboratory staffs are capable of handling safely, without the

assistance of Safety and Emergency Personnel. Every laboratory chemist should be

knowledgeable in handling such minor spills. Spill kits with instructions, absorbents,

reactants, and protective equipment should be available to clean up minor spills. At any time

the spill kits are to be fully operational and after use of a spill kit, the used material is to be

replaced immediately.

Note that only Safety and Emergency Personnel are authorised to execute major chemical

spill clean-up operations.

2.3 Description

Chemical spills can be described into two major groups.

Minor spills and major spills. Minor spill in general are less than 1 litre, while Major spill

are above 2 litres.

2.3.1 Minor Chemical Spill

If the situation is not health-threatening and trained lab chemist and proper clean-up

equipment are on hand, the trained lab chemist (Buddy) may clean-up the spill and

dispose of waste materials properly.

However, even under seemingly safe conditions, it is recommended that laboratory

supervisor be consulted to be sure that the right steps are being taken to clean-up the

spill.

2.3.2 Major Chemical Spill

Where a major spill has occurred or there is a health-threatening situation, immediately

evacuate the laboratory floor or building (whatever is appropriate), shut doors to the

area and alert those in the vicinity to do the same. If necessary, pull the nearest fire

alarm and evacuate the building.

From a remote location, immediately call the PDO emergency line 5555

Have person knowledgeable of incident and laboratory supervisor assist emergency

personnel.

UIK Chemicals Management Emergency Procedure

UIK 6 Chemicals Management Emergency Procedure

2.4 Spill control

Note that the majority of chemical spills can be prevented or minimized by:

Maintaining a neat and organized work area

Performing a laboratory procedure review prior to conducting new experimental

procedures

Storing liquid chemicals in secondary containment plastic container

Keeping reagent chemical containers sealed or closed at all times, except when

removing contents

Ordering reagent chemicals in plastic or plastic coated glass containers whenever

possible

Using secondary containment to store and move chemicals.

2.4.1 Emergency procedure for major chemical spill

2.4.1.1 Evacuate

Leave the spill area; alert others on spill area and direct/assist them in leaving.

Without endangering yourself; remove victims to fresh air, remove contaminated

clothing and flush contaminated body and eyes for 15 minutes. If anyone has been

injured or exposed to toxic chemicals or harmful vapours, call 5555 and seek medical

attention immediately.

2.4.1.2 Confine

Close doors and isolate the area. Prevent non-trained staff from entering the spill area.

2.4.1.3 Report

After reaching the safe area, call emergency 5555

Report that this is an emergency; provide your name, phone and location: location of

spill, the name and amount of chemical spilled; extent of injuries; safety route to the

spill.

Muster your team and when required report condition of assembled staff

Stay by phone and emergency team will advice through you as soon as possible.

Emergency team will clean up or stabilize spills, which are considered high hazard (fire,

health or reactivity hazard).

In the case of a small spill and low hazard situation, Laboratory supervisor will advise

you on what precautions and protective equipment to use.

2.4.1.4 Secure

Until emergency response personnel arrives: block off the area’s leading to the spill,

lock doors, post signs and warning tape, and alert others of the spill.

Post non critical staff in assemble area.

Post knowledgeable staff by commonly used entrances to the area to warn staff of the

situation and direct them to the safe zone. After an accident, laboratory supervisor must

prepare a complete incident report within 24 hours.

2.5 General Spill Cleanup Procedures (minor spills)

In the event of a chemical spill, only trained laboratory chemist are to handle the incident.

Immediately evacuate the lab and notify laboratory supervisor if there is a possibility of an

acute respiratory hazard present or if you need assistance to clean up the spill.

Never proceed to clean up a spill if you do not know the hazards associated with the

chemical or if you are unsure of how to clean up the spill. If anyone is injured or

contaminated, immediately report to PDO emergency team and begin decontamination

measures or first aid, if trained.

Use the personal protective equipment from the spill kit; splash goggles and nitrile/Silver

Shield with combination gloves.

Always ask for assistance from laboratory supervisor/chemist. They should use splash

goggles, nitrile/Silver Shield in combination with gloves.

Make sure that all forms of local exhaust i.e. fume hoods, are operating. It is normally not

advisable to open the windows.

If broken glass is involved, do not pick it up with your gloved hands. Use the scoop or tongs

to place it in the bag, and then place the bag in a strong cardboard box or plastic container.

Follow the procedures provided below based on the class and type of chemical.

All tools used in the clean up need to be decontaminated (plastic scoop, tongs, etc.). Remove

all gross contamination with a wet paper towel. Dispose of the contaminated paper towels as

waste. Rinse the tools off with large amounts of water.

Dispose of the gloves as waste. Dry the tools off and place back into the spill kit along with

the splash goggles.

Disposal of chemical spill is done as SP-1009 HSE Specification – Waste management.

2.5.1 Liquid Spills –clean up.

2.5.1.1 Non flammable liquids

Spread the chemical spill powder over the spill starting with the edges first. This will help to

confine the spill to a smaller area. Spread enough powder over the spill to completely cover

the liquid. When the absorbent action is complete there should be no free liquid.

Use plastic scoop to ensure that the liquid was completely absorbed by the powder. Pick up

the powder with scoop and place in the polyethylene bag.

Wipe the area down with a wet paper towel. Dispose of paper towel with the waste generated

from the spill cleanup. Seal bag and disposal at designated area.

In case of a spill of Mercury a special emergency procedure should be followed.

2.5.1. 2 Flammable Liquid Spills

Control all sources of ignition.

Lay the chemical spill pads over the spill. These pads are design to suppress the vapours

emitted by a volatile liquid. Allow pads to completely soak up liquid.

Pick up pads with tongs or other device that minimizes direct contact with a gloved hand.

Place in the polyethylene bag.

Wipe the area down with a wet paper towel. Dispose of paper towel with the waste

generated from the spill cleanup. Seal bag and disposal at designated area.

Carbon Disulfide (CS2) to be specified on separate procedure.

UIK Chemicals Management Emergency Procedure

UIK 8 Chemicals Management Emergency Procedure

2.5.2 Solid Spills – clean up

Use the plastic scoop to place the spilled material into the polyethylene bag.

Care should be taken so as not to create dust or cause the contaminated powder to become

airborne. After the bulk of the material is cleaned up.

Wet a spill pad and wipe the area down. Place the pads into the polyethylene bag. Wipe the

area down with a wet paper towel.

Dispose of paper towel with the waste generated from the spill cleanup. Seal bag and disposal

at designated area.

Iron Sulphide contaminated materials to be specified on separate procedure.

Note: Precautions must be taken to minimize exposure to the spilled chemical. Be careful

not to step in the spilled material and track it around.

If the spill is too large for you to handle, involves more that 500 ml of any hazardous

material, listed in the table below; highly toxic, or reactive chemical is a threat to personnel,

laboratory staffs or the public; call for assistance.

c. Inhalation Remove victim to fresh air.

Get medical attention immediately. Inform medical personnel that injury involves

hydrofluoric acid and give them a copy of the material safety data sheet.

Have Oxygen and Air musk with positive pressure available.

Laboratory that uses HF should have chemical resistance suits available.

2.9 CHEMICAL SPILL KIT CONTENTS

Every laboratory that uses chemicals must have access to a spill control kit. The key to an

effective spill kit are location and content. Spill kits should be strategically located around

work areas in fixed locations so they will be easily accessible. Although most spill kit

contents are common items which may be found throughout the lab, they must be

consolidated for emergency use.

Spill kits can be purchased through most supply vendors that sell chemicals or safety

supplies. In addition, spill kits and absorbent material can be ordered through PDO Stores.

Spill kits should be checked periodically, and immediate restored after each use.

a. Absorbents: Universal Spill Absorbent - 1:1:1 mixture of Flor-Dri (or unscented kitty litter), Sodium

Bicarbonate and sand. This all purpose absorbent is good for most chemical spills

including solvents, acids and base. Avoid use of Sodium Bicarbonate in case of

Hydrofluoric Acid, using Sodium Bicarbonate leads to the formation of Sodium Fluoride

which is considerably more toxic that Calcium Fluoride.

Acid Spill Neutralizer - sodium bicarbonate, sodium carbonate, or calcium carbonate.

Alkali (Base) Neutralizer - sodium bisulphate.

Solvents/Organic Liquid Absorbent - Inert absorbents such as vermiculite, clay, sand,

Flor-Dri, and Oil-Dri.

Bromine Neutralizer - 5% solution of sodium thiosulfate and inert absorbent.

Hydrofluoric Acid - HF compatible spill pillow or neutralize with lime and transfer to a

polyethylene container.

Mercury absorbent or Sulphur powder materials.

Mercury Spill Kit - Aspirator Bulb and Mercury Decontaminating Powder
