  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 68°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 68°C use a closed system and ventilation.  Use dry powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Rest. Seek medical attention if you feel unwell.
