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
violently with
oxidants
causing fire and explosion hazard.
Attacks plastic.
Occupational Exposure Limits:
TLV: (as hexane isomers) 500 ppm as TWA; 1000 ppm as STEL; (ACGIH 2008).
MAK: (as hexane isomers) 500 ppm, 1800 mg/m3
Peak limitation category: II(2); Pregnancy risk group: D;
(DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour.
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:
