Important Data
|
Physical State; Appearance:
COLOURLESS
,
VISCOUS
,
HYGROSCOPIC LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
and
on burning
producing
toxic and corrosive gases
including
nitrogen oxides
.
The substance is a medium strong base.
Reacts with cellulose nitrate
causing fire and explosion hazard.
Reacts
violently with
strong acids
and
strong oxidants
.
Attacks copper, aluminium and their alloys, and rubber.
Occupational Exposure Limits:
TLV: as TWA 3 ppm; as STEL 6 ppm; (ACGIH 2004).
MAK: sensitization of skin (Sh);
Pregnancy risk group: C;
(DFG 2004).
EU OEL: 2.5 mg/m3 1 ppm as TWA 7.6 mg/m3 3 ppm as STEL (skin) (EU 2006).
OSHA PEL: TWA 3 ppm (6 mg/m3)
NIOSH REL: TWA 3 ppm (8 mg/m3) ST 6 ppm (15 mg/m3)
NIOSH IDLH: 30 ppm See: 141435
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
by ingestion
and
through the skin.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance
is corrosive to
the respiratory tract
,
the skin
and
the eyes.
Corrosive on ingestion.
The vapour
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
The substance may cause effects on the
central nervous system
.
Exposure could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
