VISCOUS
HYGROSCOPIC LIQUID
OR CRYSTALS
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance is a weak base.
Reacts
with
oxidants
.
The substance decomposes
on burning
producing
toxic and corrosive fumes
including
nitrogen oxides
.
Occupational Exposure Limits:
TLV: 5 mg/m3 as TWA; (ACGIH 2003).
MAK not established.
(DFG 2008).
|
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 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.
