  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 86°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 86°C use a closed system and ventilation.  Use foam, dry powder, carbon dioxide.   

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Use ventilation.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes   Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion See Effects of short-term exposure  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
