  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Above 57°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 57°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, powder, foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Tremor. Drowsiness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
