Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
The substance can form explosive peroxides on contact with strong oxidants such as acetic acid, nitric acid, hydrogen peroxide.
Reacts with chloroform and bromoform under basic conditions,
causing fire and explosion hazard.
Attacks plastic.
Occupational Exposure Limits:
TLV: 500 ppm as TWA, 750 ppm as STEL; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004).
MAK: 500 ppm 1200 mg/m3
Peak limitation category: I(2); Pregnancy risk group: D;
(DFG 2006).
OSHA PEL: TWA 1000 ppm (2400 mg/m3)
NIOSH REL: TWA 250 ppm (590 mg/m3)
NIOSH IDLH: 2500 ppm 10%LEL See: 67641
|
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; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The vapour
irritates
the eyes
and
the respiratory tract.
The substance may cause effects on the
central nervous system
,
liver
,
kidneys
and
gastrointestinal tract
.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
The substance may have effects on the
blood
and
bone marrow
.
