producing
toxic fumes
including
nitrogen oxides
,
ammonia
.
Reacts violently with strong oxidants producing toxic fumes.
Occupational Exposure Limits:
TLV: 5 mg/m3 as TWA; A5 (not suspected as a human carcinogen); (ACGIH 2004).
MAK: (Inhalable fraction) 5 mg/m3
Peak limitation category: I(2); Pregnancy risk group: C;
(DFG 2004).

|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour or dust.
Inhalation Risk:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C
; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance
is irritating to
the skin
.
The vapour
is irritating to
the eyes
and
the respiratory tract
.
Inhalation of the vapour may cause effects on the central nervous system.
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
nervous system
liver
.
