4. FIRST - AID MEASURES
First Aid - Eyes
Immediately flood the eyes with plenty of water for at least 15 minutes, holding the eye open
Obtain medical attention urgently.
First Aid - Skin
Wash skin thoroughly with soap and water. Obtain medical attention if blistering occurs or redness
persists.
First Aid - Ingestion
Wash mouth with water. Do not induce vomiting
If any material enters the lungs, for example during swallowing or vomiting, obtain medical attention
urgently.
First Aid - Inhalation
Remove from exposure. Keep warm and at rest.
If there is difficulty in breathing, give oxygen. If breathing stops or gives signs of failing, give artificial
respiration. If heart beat absent, give external cardiac compression. (CPR)
Obtain medical attention
Advice to Physicians
Treat symptomatically. Keep under medical surveillance for 48 hours if aspiration could have occurred.
5. FIRE - FIGHTING MEASURES

Protection For Firefighters
Wear self contained breathing apparatus.
6. ACCIDENTAL RELEASE MEASURES
Personal Precautions
Consider need for evacuation. Eliminate all sources of ignition. Wear appropriate clothing. Wear
respiratory protection. Beware of vapours accumulating to form explosive concentrations.
Environmental Precautions
Try to prevent the material from entering drains or water courses. Advise Authorities if spillage has
entered water courses or sewer or has contaminated soil or vegetation.
Spillages
Contain or absorb using earth, sand or other inert material. Transfer into suitable containers for recovery
or disposal. Take precautionary measures against static discharges. Beware of gas accumulating to form
explosive concentrations.
7. HANDLING AND STORAGE
Handling
Containers, even those that have been emptied, can contain vapours. Do not cut, drill, weld or similar
operations on or near empty containers
Use in well ventilated area. Adequate ventilation should be provided if there is a risk of vapour build up.
Avoid inhaling vapour. Avoid contact with eyes, skin and clothing.
Never use air pressure to transfer material.
Storage
Storage temperature should be kept below 25掳C.
Storage area should be well ventilated. Store away from heat and ignition.

Printed 8-Jan-04 026/002 Compiled 1999-04-30
Storage and transfer equipment should be adequately earthed and bonded to prevent accumulation of
static charges.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
OCCUPATIONAL EXPOSURE GUIDELINES:
Occupational Health and Safety Act, 1993
Regulations For Hazardous Chemical Substances, 1995 Table 1.
TWA OEL CL 100 ppm (styrene)
ENGINEERING CONTROL MEASURES
Provide good mechanical ventilation with a non sparking, grounded ventilation system exhausting directly to
the outside, to control airborne levels below the OEL above, and separate from other exhaust ventilation
systems. Care should be taken in controlling the emission of fumes into the environment, to meet the local
regulations. Electric lighting and plugs to be explosion proof. Ensure that eyewash stations and safety
showers are proximal to the workstation location.
PERSONAL PROTECTION EQUIPMENT
- RESPIRATORY PROTECTION.
If TWA OEL CL level above is exceeded , then suitable respiratory protection must be worn. Up to 500 ppm a
chemical cartridge respirator with organic vapour cartridge(s). Above 500 ppm then full face supplied air
respirator, or self contained breathing apparatus should be used. Note that the IDL (immediately dangerous
to life or health) concentration of styrene is 700 ppm.
- HAND PROTECTION.
Impervious gloves. Evaluate the resistance of the product under conditions of use.
- EYE PROTECTION
Wear approved safety glasses or chemical goggles or a face shield. Have an emergency eyewash station
readily available in the working area.
- SKIN & BODY PROTECTION
Impervious gloves, coveralls, boots, and/or other resistant protective clothing. Have a safety shower/ eye
wash fountain readily available in the immediate work area.
PERSONAL PROTECTION COMMENTS
Dust generated by grinding or polishing finished products is regarded as hazardous and precautions should
be taken to ensure dust concentrations to be maintained below a TWA OEL value of 10 mg m-3 . Where dust
concentrations exceed these values, appropriate dust masks should be worn.
OTHER PROTECTIVE MEASURES
