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
oxidants
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 200 ppm as TWA, 250 ppm as STEL; (skin); BEI issued; (ACGIH 2004).
MAK:
Pregnancy risk group: C
(DFG 2004).
EU OEL: 260 mg/m3 200 ppm as TWA (skin) (EU 2006).
OSHA PEL: TWA 200 ppm (260 mg/m3)
NIOSH REL: TWA 200 ppm (260 mg/m3) ST 250 ppm (325 mg/m3) skin
NIOSH IDLH: 6000 ppm See: 67561
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation and 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.
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
central nervous system
, resulting in loss of consciousness.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
The substance may have effects on the
central nervous system
, resulting in persistent or recurring headaches and impaired vision.
