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:
Heating may cause violent combustion or explosion.
Reacts with strong oxidants.
Occupational Exposure Limits:
TLV: 300 ppm as TWA; (ACGIH 2004).
MAK:
Carcinogen category: 3A;
(DFG 2004).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
by ingestion.
Inhalation Risk:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
irritates
the eyes,
the skin
and
the respiratory tract.
The substance may cause effects on the
kidneys
,
liver
and
nervous system
.
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
