  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Above 63°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 63°C use a closed system and ventilation.  Use water spray, powder, foam, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness. Pain.  Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: filter respirator for ammonia and organic ammonia derivatives adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Cover the spilled material with inert absorbent. 

According to UN GHS Criteria
