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, powder, carbon dioxide. 
EXPLOSION Above 26°C explosive vapour/air mixtures may be formed.  Above 26°C use a closed system, ventilation and explosion-proof electrical equipment.   
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink.
