The substance decomposes
on heating
producing
toxic fumes
,
including
arsenic fumes
and
chlorine
.
Reacts
with
strong oxidants
.
Occupational Exposure Limits:

|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol.
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 skin
.
The substance may cause effects on the
nervous system
.
Exposure at high levels could cause lowering of consciousness.
Inhalation of high levels of its aerosol may cause lung oedema (see Notes).
The effects may be delayed.
Exposure at high levels may result in death.
Effects of Long-Term or Repeated Exposure:

|
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.
