Important Data
|
Physical State; Appearance:
WHITE
CRYSTALLINE POWDER
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing toxic fumes including nitrogen oxides.
Occupational Exposure Limits:
TLV: 10 mg/m3 as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: sensitization of skin (Sh);
Germ cell mutagen group: 3A
(DFG 2005).

NIOSH IDLH: N.D. See: IDLH INDEX
|
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 on spraying or when dispersed, especially if powdered.
Effects of Short-Term Exposure:
The substance
irritates
the skin.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
Animal tests show that this substance possibly causes toxic effects upon human reproduction.
Animal tests show that this substance possibly causes malformations in human babies.
