Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH PUNGENT ODOUR.
Physical Dangers:
Chemical Dangers:
The substance will polymerize
under the influence of all common metals except nickel and lead, with evolution of corrosive fumes (hydrogen chloride - see ICSC 0163),
with fire or explosion hazard.
On combustion, forms toxic and corrosive fumes (hydrogen chloride).
Reacts vigorously with strong oxidants.
Attacks many metals in presence of water.
Occupational Exposure Limits:
TLV: 1 ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2001).
MAK: skin absorption (H);
Carcinogen category: 2;
(DFG 2004).
OSHA PEL: TWA 1 ppm (5 mg/m3)
NIOSH REL: C 1 ppm (5 mg/m3) 15-minute
NIOSH IDLH: 10 ppm See: 100447
|
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 can be reached rather quickly on evaporation of this substance at 20°C; on spraying much faster.
Effects of Short-Term Exposure:
The substance
is corrosive to
the eyes.
The vapour
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Inhalation of the vapour or aerosol may cause lung oedema (see Notes).
The substance may cause effects on the
central nervous system
, resulting in unconsciousness.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the liver andkidneys
, resulting in tissue lesions.
This substance is possibly carcinogenic to humans.
Animal tests show that this substance possibly causes toxicity to human reproduction or development.

N O T E S
|
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
