ODOURLESS
WHITE, LUSTROUS CRYSTALS
OR POWDER.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating or
on burning
producing toxic and corrosive fumes including sulfur oxides.
The solution in water is a medium strong acid.
Reacts with alkalis and
attacks many metals in presence of water.
Occupational Exposure Limits:
TLV (as Al soluble salt): 2 mg/m3 (ACGIH 1993-1994).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation 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
irritates
the eyes,
the skin and
the respiratory tract.
Corrosive on ingestion.
Effects of Long-Term or Repeated Exposure:
