  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 93°C explosive vapour/air mixtures may be formed.  NO open flames. NO contact with hot surfaces.  Above 93°C use a closed system, ventilation and explosion-proof electrical equipment.  Use foam, powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat.  Use ventilation.  Fresh air, rest. Artificial respiration may be needed. 
Skin Redness. Roughness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest. Refer for medical attention .
