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 slowly with calcium hypochlorite, silver oxide and ammonia,
causing fire and explosion hazard.
Reacts
violently with
strong oxidants
such as nitric acid, silver nitrate, mercuric nitrate or magnesium perchlorate,
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 1000 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 500 ppm, 960 mg/m3
Peak limitation category: II(2); Carcinogen category: 5; Pregnancy risk group: C; Germ cell mutagen group: 5;
(DFG 2004).
OSHA PEL: TWA 1000 ppm (1900 mg/m3)
NIOSH REL: TWA 1000 ppm (1900 mg/m3)
NIOSH IDLH: 3300 ppm 10%LEL See: 64175
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour and
by ingestion.
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
irritates
the eyes.
Inhalation of high concentration of vapour may cause irritation of the eyes and respiratory tract.
The substance may cause effects on the
central nervous system
.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
The substance may have effects on the upper
respiratory tract
and
central nervous system
, resulting in irritation, headache, fatigue and lack of concentration.
