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