TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Highly flammable in powder form. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks, and NO smoking. NO contact with moisture or acid.	Dry sand. Special powder. NO hydrous agents. NO water.
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.	Rinse skin with plenty of water or shower.
EYES	Redness. Pain.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION		Do not eat, drink, or smoke during work.	Rinse mouth.

PHYSICAL STATE; APPEARANCE:
SILVERY-WHITE METALLIC SOLID IN VARIOUS FORMS.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance may spontaneously ignite on contact with air if finely divided or on heating. Upon heating, toxic fumes are formed. The substance is a strong reducing agent and reacts violently with oxidants and many other substances causing fire and explosion hazards. Reacts with moisture or acids, evolving combustible gas (Hydrogen - see ICSC # 0001), causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by ingestion.

INHALATION RISK:

EFFECTS OF SHORT-TERM EXPOSURE:

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
