4. FIRST AID MEASURES
GENERAL INFORMATION: Remove contaminated or saturated clothing immediately.
INHALATION: Possible discomfort. Irritation of mucous lining (nose, throat, eyes) cough, sneezing, flow of tears.
Take affected persons out into fresh air. In case of persistent discomfort seek medical attention.
SKIN: When contact with skin, rinse immediately with soap and water.
EYE: Irrigate with eyewash solution or clear water, holding the eyelids apart, for at least 5 minutes. Obtain
immediate medical attention.
INGESTION: Do not induce vomiting. Wash out mouth with water and give 200-300 ml (half a pint) of water to drink.

UNSUITABLE MEDIA: Full water jet
PARTICULAR DANGER CAUSED BY MATERIAL, ITS COMBUSTION PRODUCTS OR GASES PRODUCED:
Formation of flammable or explosive vapour/air mixtures possible. In the case of fire Methyl Methacrylate and Styrene
may be released.

MATERIAL SAFETY DATA SHEET
Keep away from sources of ignition. Do not smoke. Caution electrostatic charge may occur.
Usual measures for chemical fires. In case of fire, cool containers or take them to a safe place. Danger of
polymerisation. Water used to extinguish fire should not enter the drainage systems, soil, or stretches of water.
Fire residues should be disposed of in accordance with the regulations. Ensure there are sufficient retaining
facilities for water used to extinguish the fire. Contaminated fire-extinguishing water must be disposed of in
accordance with the regulations issued by the appropriate local authorities.
6. ACCIDENTAL RELEASE MEASURES
Eliminate sources of ignition. Ensure suitable personal protection (including respiratory protection) during removal of
spillages. Prevent entry into drains. Adsorb spillages onto sand, earth or any suitable adsorbent material. Do not
adsorb onto sawdust or other combustible materials. Transfer to a container for disposal or recovery.
7. HANDLING AND STORAGE
HANDLING: Avoid contact with skin and eyes. Stir and shake well before use.
Avoid inhalation of high concentration of vapors. Use only in well ventilated areas.
The vapour is heavier than air; beware of pits and confined spaces. Take precautionary measures
against static discharges.
STORAGE: Keep only in original container. Store in cool dry place away from heat, sparks, flame and direct
sunlight.
Keep container closed to prevent water absorption and contamination. Keep away from sources of
ignition 鈥? No Smoking. Ensure there is good room ventilation.
STORAGE TEMPERATURE: Preferably not exceeding 25 潞C.
INDUSTRIAL HYGIENE PRACTICES: Wash face and hands thoroughly with the soap and water after use and before
eating, drinking, smoking or applying cosmetics.
8. EXPOSURE CONTROL / PERSONAL PROTECTION
Provide adequate ventilation, including appropriate local extraction, to ensure that the defined occupational exposure
limit is not exceeded.
Considerati ons should be given to the work procedures involved and the potential extent of exposure as they may
determine whether a higher level of protection is required.
The following information is given as general guidance.
RESPIRATORS: Wear suitable respiratory protective equipment if exposure to levels above the occupational exposure
limit is likely. A suitable mask with filter type A may be appropriate. In the event of formation of
particularly high levels of vapor a self-contained breathing apparatus may be appropriate.
EYE PROTECTION: Safety glasses or chemical splash goggles.
GLOVES: Wear suitable gloves. Rubber or latex gloves offer the best protection. Gloves should be changed regularly
and if excessive exposure has occurred.
OTHER: Wear suitable protective clothing.
