  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion on contact with acids, halogens or water.  NO contact with water, acids or halogens. NO open flames, NO sparks and NO smoking.    Use special powder, dry sand. NO other agents.  Combat fire from a sheltered position. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat. Burning sensation.  Use closed system or ventilation.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Pain. Blisters. Serious skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Severe deep burns. Loss of vision.  Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .
