Important Data
|
Physical State; Appearance:
ODOURLESS
COLOURLESS
COMPRESSED GAS.
Physical Dangers:
The gas is heavier than air
and may accumulate in low ceiling spaces causing deficiency of oxygen.
Chemical Dangers:
On contact with hot surfaces or flames this substance decomposes forming hydrofluoric acid.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.
Effects of Short-Term Exposure:
Rapid evaporation of the liquid may cause frostbite.
The substance may cause effects on the cardiovascular system
, resulting in
cardiac disorders
.
Exposure at high levels may result in unconsciousness.
See Notes.
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|
Boiling point: -127.8°C
Melting point: -183.6°C
Solubility in water:
none
|
Relative vapour density (air = 1): 3.04
Auto-ignition temperature: >1100°C
|
|
Environmental
Data
|
This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.
|
|
N O T E S
|
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Card has been partly updated in October 2005. See section Emergency Response.
