Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
or
on burning
producing
toxic fumes
(
nitrogen oxides
).
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

The substance
is irritating to
the eyes
and
the respiratory tract
.
Inhalation of dust may cause asthmatic reactions (see Notes).
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
Repeated or prolonged contact may cause skin sensitization.
Repeated or prolonged inhalation exposure may cause asthma.
