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

EXPOSURE
Inhalation	Cough.	Avoid inhalation of fine dust and mist. Ventilation, local exhaust, or breathing protection.	Fresh air, rest.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Burning sensation.	Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into containers. Remove remainder with fine water spray. (Extra personal protection: P2 filter respirator for harmful particles.)

EMERGENCY RESPONSE	STORAGE
NFPA Code: H1; F1; R0	Separated from oxidants. Dry.

IMPORTANT DATA
Physical State; Appearance COLOURLESS TO WHITE HYGROSCOPIC CRYSTALS Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Reacts violently with oxidants. Occupational exposure limits TLV not established.	Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. Effects of short-term exposure The substance is irritating to the eyes and the respiratory tract.
