Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour,
through the skin
and
by ingestion.
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
,
the skin
and
the respiratory tract
.
The vapour
irritates
the eyes,
the skin
and
the respiratory tract.
The substance may cause effects on the
liver
and
kidneys
, resulting in
impaired functions
.
Exposure above the OEL may result in death.
Medical observation is indicated.
