Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Vapours are uninhibited and may polymerize, blocking vents.
Chemical Dangers:
The substance may polymerize spontaneously
due to warming,
under the influence of
light
and
on contact with peroxides.
Reacts
violently with
strong oxidants
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 2 ppm as TWA; A4 (not classifiable as a human carcinogen); SEN; (ACGIH 2002).
MAK: 2 ppm, 11 mg/m3
Peak limitation category: I(2);
sensitization of skin (Sh);
Pregnancy risk group: C;
(DFG 2006).
OSHA PEL: none
NIOSH REL: TWA 10 ppm (55 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
through the skin.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
