IMPORTANT DATA
Physical State; Appearance Routes of exposure
FUMING RED TO BROWN LIQUID, WITH PUNGENT ODOUR. The substance can be absorbed into the body by inhalation of
its vapour and by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air.
A harmful contamination of the air can be reached very quickly
on evaporation of this substance at 20/C.
Chemical dangers
Upon heating, toxic fumes are formed. The substance is a

The effects may be delayed. Medical observation is indicated.
Corrosive on ingestion.
Occupational exposure limits
TLV: 0.1 ppm as TWA; 0.2 ppm as STEL; (ACGIH 2004).
EU OEL: 0.1 ppm, 0.7 mg/m3 as TWA; (EU 2004). Effects of long-term or repeated exposure
Repeated or prolonged inhalation exposure may cause
asthma-like syndrome (RADS).
PHYSICAL PROPERTIES
Boiling point: 58.8/C Vapour pressure, kPa at 20/C: 23.3
Melting point: -7.2/C Relative vapour density (air = 1): 5.5
Relative density (water = 1): 3.1 Relative density of the vapour/air-mixture at 20/C (air = 1): 2.0
Solubility in water, g/100 ml at 20/C: 3.1
ENVIRONMENTAL DATA
NOTES
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 are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Thiosulphate has been used to neutralize spills.
