Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour mixes well with air, explosive mixtures are easily formed.
Chemical Dangers:
Reacts with strong oxidants
,
strong acids
and
strong bases
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 150 ppm as TWA; (ACGIH 2003).
MAK: 100 ppm, 480 mg/m3
Peak limitation category: I(2); Pregnancy risk group: C;
(DFG 2003).
OSHA PEL: TWA 150 ppm (700 mg/m3)
NIOSH REL: TWA 150 ppm (700 mg/m3)
NIOSH IDLH: 1300 ppm 10%LEL See: 110190
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The vapour
is mildly irritating to
the eyes
and
the respiratory tract
.
The substance may cause effects on the
central nervous system
.
Exposure far above the OEL could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
