TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION Above 94°C explosive vapour/air mixtures may be formed.  Above 94°C use a closed system and ventilation.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation   Use ventilation.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Do NOT induce vomiting. Seek medical attention if you feel unwell.
