CRYSTALS.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating or
on burning
producing
toxic and corrosive fumes
including
hydrogen bromide
and
nitrogen oxides
.
Reacts with some metals, amines and alkaline compounds.
Occupational Exposure Limits:
TLV not established.
MAK: IIb (not established but data is available) skin absorption (H); sensitization of skin (Sh); (DFG 2006).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol,
through the skin
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
