PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS COLOURLESS COMPRESSED GAS. Physical dangers The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. Chemical dangers Decomposes on contact with hot surfaces or flames. Decomposes above 52°C . This produces hydrofluoric acid. Incompatible with certain metal powders (aluminium, zinc, beryllium).	Formula: CF₄ Molecular mass: 88.01 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

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure Exposure to cold gas could cause frostbite. The substance may cause effects on the cardiovascular system. This may result in cardiac disorders. Exposure at high levels could cause unconsciousness. See Notes.	Inhalation risk On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

Effects of short-term exposure
Exposure to cold gas could cause frostbite. The substance may cause effects on the cardiovascular system. This may result in cardiac disorders. Exposure at high levels could cause unconsciousness. See Notes.

Inhalation risk
On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
It is strongly advised not to let the chemical enter into the environment because it is persistent.

NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
