Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
Causes watering of the eyes.
The substance
is severely irritating to
the eyes
.
The substance
is irritating to
the skin
and
the respiratory tract
.
Inhalation of vapour or aerosol may cause lung oedema (see Notes).
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
Repeated or prolonged contact may cause skin sensitization.

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 are therefore essential.
The odour warning when the exposure limit value is exceeded is insufficient.
Chemical Mace, CAP, CN are trade names.
Do NOT take working clothes home.
