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.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
Reacts with strong oxidants
causing fire and explosion hazard.
Attacks some forms of plastics, rubber and coatings.
Occupational Exposure Limits:
TLV: 300 ppm as TWA; (ACGIH 2004).
MAK: 500 ppm, 2400 mg/m3
Peak limitation category: II(2); Pregnancy risk group: D;
(DFG 2008).
OSHA PEL: TWA 500 ppm (2350 mg/m3)
NIOSH REL: TWA 75 ppm (350 mg/m3) C 385 ppm (1800 mg/m3) 15-minute
NIOSH IDLH: 1000 ppm 10%LEL See: 111659
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
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
,
the skin
and
the respiratory tract
.
Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis.
Exposure to high concentrations of vapour could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
The liquid defats the skin.
