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 will be reached rather slowly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is mildly irritating to
the eyes
and
the skin
.
The substance may cause effects on the
blood
, resulting in
the formation of methaemoglobin.
Medical observation is indicated.
The effects may be delayed.
