Important Data
|
Physical State; Appearance:
YELLOWISH OR COLOURLESS LIQUID
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing
toxic and corrosive fumes
.
Reacts
with
water
to produce
heat and corrosive fumes.
The solution in water is a strong acid, it reacts violently with bases and is corrosive.
Occupational Exposure Limits:
TLV (as Se): 0.2 mg/m3 (ACGIH 2000).
MAK: (as Se) (Inhalable fraction) 0.05 mg/m3
Peak limitation category: II(4); Carcinogen category: 3B; Pregnancy risk group: C;
(DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour,
and by ingestion of the liquid.
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 corrosive to
the eyes,
the skin and
the respiratory tract.
Inhalation of the vapour may cause lung oedema (see Notes).
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
The substance may have effects on the
respiratory tract
,
gastrointestinal tract
,
central nervous system
and
liver
, resulting in nasal irritation, persistent garlic odour, stomach pain, nervousness and
liver impairment
.

N O T E S
|
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.
Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
Do NOT take working clothes home.
