  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 82°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 82°C use a closed system and ventilation.  Use foam, dry powder, carbon dioxide.   

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
