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 bases
strong acids
and nitrates,
causing fire and explosion hazard.
Attacks plastic.
Occupational Exposure Limits:
TLV: 200 ppm as TWA; 250 ppm as STEL; (ACGIH 2004).
MAK: 100 ppm, 420 mg/m3
Peak limitation category: I(2); Pregnancy risk group: D;
(DFG 2004).
OSHA PEL: TWA 200 ppm (840 mg/m3)
NIOSH REL: TWA 200 ppm (840 mg/m3) ST 250 ppm (1050 mg/m3)
NIOSH IDLH: 1700 ppm See: 109604
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The vapour
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Exposure far above the OEL could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
