TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Finely dispersed particles form explosive mixtures in air.	Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation			Fresh air, rest.
Skin		Protective gloves.	Rinse and then wash skin with water and soap.
Eyes		Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible).
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place

EMERGENCY RESPONSE	SAFE STORAGE

IMPORTANT DATA
Physical State; Appearance COLOURLESS TO WHITE CRYSTALS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers The substance decomposes on heating or on burning producing toxic and irritating fumes including hydrogen cyanide, nitrogen oxides, and ammonia. Occupational exposure limits TLV not established. MAK not established.	Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Effects of long-term or repeated exposure When ingested in large amounts the substance may have effects on the kidneys and bladder, resulting in stone formation.
