  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 25°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 25°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, alcohol-resistant foam, carbon dioxide, powder.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Use ventilation.  Fresh air, rest.
