Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is slightly irritating to
the eyes
and
the skin
.
Exposure at high levels of the vapour may result in irritation of the eyes and upper respiratory tract.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
