	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Highly flammable. Vapour/air mixtures are explosive.	NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting.	Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Laboured breathing. Sore throat. Shortness of breath.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Skin burns. Pain. Blisters.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Redness. Pain. Blurred vision. Severe deep burns.	Wear safety spectacles, face shield 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	Diarrhoea. Sore throat. Vomiting. Abdominal pain. Burning sensation. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention . See Notes.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible. Chemical dangers Decomposes on burning. This produces toxic fumes and gases (ammonia, nitrogen oxides). The substance is a weak base. Reacts with strong oxidants and strong acids. Attacks tin, aluminium and some steels.
