, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
or
on burning
producing
toxic fumes
including
phosphorus oxides
,
sulfur oxides
,
hydrogen chloride
.
Occupational Exposure Limits:
TLV not established.
|
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.
Effects of Short-Term Exposure:
The substance may cause effects on the
nervous system
, resulting in convulsionsandrespiratory failure.Cholinesterase inhibitor.Exposure may result in death.The effects may be delayed.Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
