Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on burning
producing
irritating fumes
.
Reacts with strong oxidants
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 10 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK not established.
|
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; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The vapour
is irritating to
the eyes
and
the respiratory tract
.
The substance may cause effects on the central nervous system.
Exposure far above the OEL may result in unconsciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
The substance may have effects on the
kidneys
.
