.
Occupational Exposure Limits:
OSHA PEL: none
NIOSH REL: TWA 0.05 mg/m3 ST 0.2 mg/m3 skin
NIOSH IDLH: N.D. See: IDLH INDEX
TLV: (inhalable fraction & vapour) 0.05 mg/m3 as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2008).

Routes of Exposure:
The substance can be absorbed into the body rapidly
by inhalation,
through the skin, the eyes
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance may cause effects on the
central nervous system
, resulting in
cholinesterase inhibition.
Exposure may result in death.
Medical observation is indicated.
The effects may be delayed.
Effects of Long-Term or Repeated Exposure:
Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
