|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly 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
,
the skin
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
