| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: YELLOWISH TO WHITE LUSTROUS SOLID IN VARIOUS FORMS. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance may spontaneously ignite on contact with air (if in powder form). The substance is a strong reducing agent and reacts violently with oxidants and acids. Reacts violently with halogenated solvents. Reacts with water, forming flammable/explosive gas (hydrogen - see ICSC0001), causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: ppm; 0.5 mg/m^3 (as TWA) (ACGIH 1999). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by ingestion. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. | ||
