| FIRE |
Gives off irritating or toxic fumes (or gases) in a fire.
|
|
|
| EXPLOSION |
|
|
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
|
| EXPOSURE |
|
|
|

| TETRAFLUOROMETHANE |
ICSC: 0575 |
|
| 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.
|
| PHYSICAL PROPERTIES |
Boiling point: -127.8℃
Melting point: -183.6℃
Solubility in water: none
Relative vapour density (air = 1): 3.04
|
Auto-ignition temperature: >1100℃
|
| ENVIRONMENTAL DATA |
This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.
|
| NOTES |
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.
