  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    In case of fire in the surroundings, use appropriate extinguishing media.   

See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE. AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use closed system.  Fresh air, rest. 
Skin MAY BE ABSORBED! Redness. Pain. Burning sensation. Symptoms may be delayed.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention if skin irritation occurs. 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
