CRYSTALS
Physical Dangers:
Dust explosion possible if in powder or granular form, mixed with air.
Chemical Dangers:
Reacts
violently with
oxidants
.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol
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:
