	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.	NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.	Use water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Blue lips, fingernails and skin.	Use local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! Redness. Pain.	Protective clothing. Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
Eyes	Redness. Pain.	Wear safety goggles.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible).
Ingestion	Blue lips, fingernails and skin. Dizziness. Headache. Nausea. Confusion. Convulsions. Unconsciousness.	Do not eat, drink, or smoke during work.	Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance YELLOW-TO-ORANGE-YELLOW CRYSTALS WITH CHARACTERISTIC ODOUR. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers May explode on heating. Decomposes on heating. This produces toxic fumes including nitrogen oxides even in the absence of air. Reacts with strong oxidants. Reacts with reducing agents, strong bases, amines, zinc and tin.
