Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
and
on burning
producing toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and nitrogen oxides.
Occupational Exposure Limits:
TLV not established.
MAK: sensitization of skin (Sh);
Carcinogen category: 3B;
(DFG 2004).
|
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 on spraying or when dispersed, especially if powdered.

The substance
irritates
the eyes,
the skin
and
the respiratory tract.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
Repeated or prolonged contact may cause skin sensitization.
The substance may have effects on the
kidneys
and
gastrointestinal tract
.
