Important Data
|
Physical State; Appearance:
FUMING COLOURLESS LIQUID
, WITH PUNGENT ODOUR.
Physical Dangers:
The vapour is heavier than air.
Chemical Dangers:
The substance decomposes
on heating or
on contact with water or humidity
producing toxic and corrosive fumes including phosphoric acid, hydrogen chloride, hydrogen sulfide
, causing fire and explosion hazard.
Attacks many metals in presence of water.
Occupational Exposure Limits:
TLV not established.
MAK not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
A harmful contamination of the air can be reached very 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.
The vapour
is corrosive to
the eyes,
the skin and
the respiratory tract.
Corrosive on ingestion.
Inhalation of the vapour may cause lung oedema (see Notes).
Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis.
Exposure may result in death.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
|
|
Physical Properties
|
Boiling point: 125°C
Melting point: -35°C
Relative density (water = 1): 1.6
Solubility in water: reaction
|
Vapour pressure, kPa at 25°C: 2.9
Relative vapour density (air = 1): 5.8
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.1
|
|
Environmental Data
|
This substance may be hazardous to the environment; special attention should be given to water.
|
|
N O T E S
|
Reacts violently with fire extinguishing agents such as water, foam.
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.
Transport Emergency Card: TEC (R)-80G10.
