Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
Reacts
violently with oxidizing materials.
Attacks many plastics.
Occupational Exposure Limits:
TLV: 100 ppm as TWA; 200 ppm as STEL; (ACGIH 2004).
MAK: 100 ppm, 420 mg/m3
Peak limitation category: I(2); Pregnancy risk group: C;
(DFG 2004).
OSHA PEL: TWA 250 ppm (950 mg/m3)
NIOSH REL: See Appendix D
NIOSH IDLH: 1800 ppm See: 108214
|
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
and
the respiratory tract
.
Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis.
Exposure far above OEL could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
