Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing
toxic fumes
including
nitrogen oxides
.
Occupational Exposure Limits:
TLV: 0.1 mg/m3 A4; BEI issued; (ACGIH 2004).
MAK not established.
OSHA PEL: none
NIOSH REL: TWA 0.1 mg/m3

|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
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 may cause effects on the nervous system
, resulting in
convulsions
and
respiratory depression
.
Cholinesterase inhibitor.
The effects may be delayed.
Exposure may result in death.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
