  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 78°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 78°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, powder, foam, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Headache. Nausea.  Use ventilation.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap.
