  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Above 63°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 63°C use a closed system and ventilation.  Use water spray, foam, powder, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety spectacles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. Rest. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
