  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 76°C explosive vapour/air mixtures may be formed.  NO open flames. NO contact with acids or bases.  Above 76°C use a closed system and ventilation.  Use powder, foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Dizziness. Drowsiness. Unconsciousness. Vomiting.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness. Pain.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Further see Inhalation.  Do not eat, drink, or smoke during work. Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
