  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 82°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 82°C use a closed system and ventilation.  Use powder, carbon dioxide, foam.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Dizziness. Lethargy. Headache. Nausea. Sore throat.  Use ventilation.  Fresh air, rest. Artificial respiration may be needed. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Diarrhoea. Vomiting. Further see Inhalation.    Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .
