  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Above 68°C explosive vapour/air mixtures may be formed. Gas/air mixtures are explosive.  NO open flames.  Above 68°C use a closed system and ventilation.  Use dry powder, foam, carbon dioxide, water spray.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air. Refer for medical attention. 
Skin Redness. Pain. Skin burns.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention. 
Eyes Redness. Pain.  Wear safety goggles or face shield.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Sore throat. Burning sensation behind the breastbone. Abdominal pain.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
On combustion, forms irritating and toxic fumes including nitrogen oxides and carbon monoxide. Reacts vigorously with strong oxidants. This generates fire and explosion hazard. Attacks copper and copper alloys.
