TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Finely dispersed particles form explosive mixtures in air.	Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation	Cough.	Local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Cough.	Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: P1 filter respirator for inert particles. Sweep spilled substance into containers. Wash away remainder with plenty of water.

EMERGENCY RESPONSE	SAFE STORAGE
	Separated from strong oxidants. Dry. Well closed.

IMPORTANT DATA
Physical State; Appearance COLOURLESS TO WHITE HYGROSCOPIC CRYSTALS OR PELLETS Chemical dangers Reacts violently with strong oxidants. Occupational exposure limits TLV not established. MAK not established.	Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. Effects of short-term exposure May cause mechanical irritation to the eyes and the respiratory tract.
