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; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
and
the respiratory tract
,
and
is mildly irritating to
the skin
.
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
At high levels
the substance may cause effects on the
central nervous system
.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
