TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Flammable.	NO contact with acid(s), alcohol, oxidants and water.	Dry sand, special powder. NO water. NO carbon dioxide, foam.
EXPLOSION	Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with acid(s), alcohol, oxidants and water.	Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation		Local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Rinse skin with plenty of water or shower.
Eyes		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.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into covered and dry containers. (Extra personal protection: P2 filter respirator for harmful particles).	F Symbol R: 15-17 S: (2-)7/8-43 UN Hazard Class: 4.3 UN Pack Group: II

EMERGENCY RESPONSE	STORAGE
Transport Emergency Card: TEC (R)-43G14 NFPA Code: H0; F3; R1; (uncoated)	Separated from strong oxidants, strong bases, strong acids and water. See Chemical Dangers. Dry. Well closed.

IMPORTANT DATA

Physical State; Appearance
WHITE TO
GREY POWDER.

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air.

Chemical dangers
Reacts with water and alcohols, and violently with oxidants, strong acids, strong bases, and chlorinated hydrocarbons causing fire and explosion hazard.

Occupational exposure limits
TLV (as Al): 5 mg/m³ (as TWA) (pyro powder) (ACGIH 2000).
TLV: 10 mg/m³ (as TWA) (metal dust) (ACGIH 2000).

Routes of exposure
The substance can be absorbed into the body by inhalation.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolonged exposure to dust particles. The substance may have effects on the nervous system, resulting in impaired functions.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 2327°C Melting point: 660°C Density: 2.7 g/cm³ Solubility in water: none, reaction Auto-ignition temperature: 590°C
