Important Data
|
Physical State; Appearance:
VOLATILE COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
Reacts violently with strong oxidants.
Attacks many plastics.
Occupational Exposure Limits:
TLV: 400 ppm as TWA, 500 ppm as STEL; (ACGIH 2004).
EU OEL: 500 ppm, 2085 mg/m3 as TWA (EU 2000).
OSHA PEL: TWA 500 ppm (2000 mg/m3)
NIOSH REL: TWA 85 ppm (350 mg/m3) C 440 ppm (1800 mg/m3) 15-minute
NIOSH IDLH: 750 ppm See: 142825
|
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 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
and
the skin
.
The vapour
irritates
the eyes,
the skin
and
the respiratory tract.
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
The substance may cause effects on the
central nervous system
.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
The substance may have effects on the
liver
, resulting in
impaired functions
.
