Important Data
|
Physical State; Appearance:
WHITE CRYSTALS
OR FLAKES.
Physical Dangers:
Dust explosion possible if in powder or granular form, mixed with air.
Chemical Dangers:
The substance decomposes
on heating,
under influence of strong oxidants
producing acrid, toxic fume
, causing fire and explosion hazard.
Occupational Exposure Limits:
TLV not established.
|
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 Short-Term Exposure:
The substance slightly
irritates
the skin and
the respiratory tract.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis under the influence of UV light.
