with
strong bases
and
strong oxidants
.
Occupational Exposure Limits:
TLV not established.
MAK not established.
|
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 very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
and
the respiratory tract
.
The substance may cause effects on the central nervous system
, resulting in lowering of consciousness.
