|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is corrosive to
the eyes
and
the skin.
The vapour
is irritating to
the respiratory tract
.
Corrosive on ingestion.
The substance may cause effects on the
central nervous system
, resulting in
convulsions
and
respiratory failure
.
Cholinesterase inhibition.
Exposure may result in death.
Medical observation is indicated.
The effects may be delayed.
