|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Flammable. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames, NO sparks and NO smoking.||Use dry powder. Use foam. Use carbon dioxide.|
|EXPLOSION||Above 31°C explosive vapour/air mixtures may be formed. See Notes.||Above 31°C use a closed system, ventilation and explosion-proof electrical equipment.||In case of fire: keep drums, etc., cool by spraying with water.|
|Inhalation||Dizziness. Drowsiness. Headache. Nausea. Vomiting. Weakness. Unconciousness.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||Redness. Pain.||Protective clothing. Protective gloves.||Remove contaminated clothes. Rinse and then wash skin with water and soap.|
|Eyes||Redness. Pain.||Wear safety goggles or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Nausea. Vomiting.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Rest.|
|PACKAGING & LABELLING|
|Personal protection: chemical protection suit including self-contained breathing apparatus. Remove all ignition sources. Do NOT let this chemical enter the environment. Do NOT wash away into sewer. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.||

|The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.|
Depending on the degree of exposure, periodic medical examination is indicated.
Check for peroxides prior to distillation; eliminate if found.
Styrene monomer vapours are uninhibited and may form polymers in vents or flame arresters of storage tanks, resulting in blockage of vents.
Do NOT take working clothes home.
