Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour mixes well with air, explosive mixtures are easily formed.
Chemical Dangers:
Reacts violently with strong oxidants,strong bases,amines and isocyanates
causing fire and explosion hazard.
Attacks some plastic.
Occupational Exposure Limits:
OSHA PEL: TWA 100 ppm (475 mg/m3)
NIOSH REL: TWA 50 ppm (240 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX
TLV: 50 ppm as TWA; (ACGIH 2004).
MAK: 10 ppm, 47 mg/m3
Peak limitation category: I(2); Pregnancy risk group: D;
(DFG 2007).
|
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 substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
The substance may cause effects on the kidneys
, resulting in kidney impairment.
Exposure above the OEL could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
