NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by ingestion
and
by inhalation.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
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 cellular respiration (inhibition)
, resulting in convulsionsand respiratory failure.
The effects may be delayed.
Exposure at high levels may result in death.
Effects of Long-Term or Repeated Exposure:
