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: 0.5 mg/m3 as TWA A4 (not classifiable as a human carcinogen); (ACGIH 2008).
EU OEL: 0.5 mg/m3 as TWA (EU 2006).
|
Routes of Exposure:
The substance can be absorbed into the body
by ingestion.
Inhalation Risk:
Effects of Short-Term Exposure:
The substance
irritates
the eyes,
the skin and
the respiratory tract.
Effects of Long-Term or Repeated Exposure:
