Physical Dangers:
Chemical Dangers:
The substance will polymerize
under the influence of
temperatures above 130°C
or
under the influence of
base(s)
with fire or explosion hazard.
The substance decomposes
on heating
producing
toxic and corrosive gases
,
including
hydrogen cyanide
and
nitrogen oxides
.
Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001).
Occupational Exposure Limits:
TLV not established.
OSHA PEL: none
NIOSH REL: TWA 3 ppm (8 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
through the skin
and
by ingestion
.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is severely irritating to
the eyes
,
the skin
and
the respiratory tract
.
The substance may cause effects on the cellular respiration (inhibition)
, resulting in
convulsions
,
cardiac disorders
and
respiratory failure
.
Exposure at high levels may result in death.
Medical observation is indicated.
The effects may be delayed.
