Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
Reacts with strong oxidants.
Occupational Exposure Limits:
TLV: 25 ppm as TWA, 40 ppm as STEL; (skin); (ACGIH 2004).
MAK: 20 ppm, 85 mg/m3
Peak limitation category: I(1); Pregnancy risk group: D;
(DFG 2006).
OSHA PEL: TWA 25 ppm (100 mg/m3) skin
NIOSH REL: TWA 25 ppm (100 mg/m3) ST 40 ppm (165 mg/m3) skin
NIOSH IDLH: 400 ppm See: 108112
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour
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.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Exposure could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
