|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol
and
by ingestion.
Inhalation Risk:
A harmful concentration of airborne particles can be reached quickly when dispersed.

The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.

N O T E S
|
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.
Health effects of exposure to the substance have not been investigated adequately.
