|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol,
through the skin
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
The substance may cause effects on the
nervous system
, resulting in
convulsions
and
respiratory failure
.
Cholinesterase inhibitor.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|

|
Solubility in water, g/100 ml: none
Vapour pressure, Pa at 25°C: 0.106
|
|
Environmental
Data
|
The substance is very toxic to aquatic organisms.
This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
