Important Data
|
Physical State; Appearance:
COLOURLESS
LIQUID
Physical Dangers:
Chemical Dangers:
The substance polymerizes rapidly, especially
under the influence of moisture.
The substance decomposes
on heating
or
on burning
producing toxic and irritating fumes/gases
including
nitrogen oxides
.
Occupational Exposure Limits:
TLV: 0.2 ppm as TWA; (ACGIH 2008).
MAK: 2 ppm, 9.2 mg/m3
Peak limitation category: I(1); Pregnancy risk group: D;
(DFG 2008).
OSHA PEL: none
NIOSH REL: TWA 2 ppm (8 mg/m3) ST 4 ppm (16 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour.
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 vapour
is irritating to
the eyes
and
the respiratory tract
.
Inhalation of vapour may cause asthmatic reactions (see Notes).
Immediately glues (sticks to) biological tissues.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.

Environmental Data

|
N O T E S
|
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of asthma 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.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
