Air, nitrogen and sulfur hexafluoride are the three most commonly used gaseous dielectrics.

The density of sulfur hexafluoride is relatively high at room temperature and pressure due to the gas's large molar mass.

Sulfur hexafluoride has an anesthetic potency slightly lower than nitrous oxide.

The levels of sulphur hexafluoride in the Canadian atmosphere are unknown.

Perhaps just as well because sulphur hexafluoride is thought to have damaging effects on the ozone.

Finally, trace gases such as the halocarbons and sulphur hexafluoride have no significant natural sources.

Sulphur hexafluoride (SF) is used primarily as an insulation gas.

Not only have health fears recently been raised over the insulating compound sulphur hexafluoride (Chem.

Sulphur hexafluoride is used in magnesium production as a cover gas to prevent oxidization of the molten metal.

These are usually constructed as type (e) but use a gas other than air such as SF6, (sulphur hexafluoride).

Sulphur hexafluoride itself is harmless except in a confined space, where it displaces oxygen and can asphyxiate people.

Sulphur hexafluoride (SF6) is emitted during magnesium production.

The arching hazards associated with oil filled switchgear led to the development of the gas-filled design using sulphur hexafluoride (SF6).

If sulphur hexafluoride is subjected to electrical sparking in the presence of oxygen, it degrades, releasing toxic breakdown products.

In fact there are a number of applications where no alternative is possible, for example fire protection and the use of sulphur hexafluoride in switch gear.

Inorganic fluoride compounds (except sulphur hexafluoride) are not expected to remain in the troposphere very long or migrate to the stratosphere.

One gram of sulphur hexafluoride released into the atmosphere, for example, has about 22 000 times the effect of a gram of carbon dioxide.

Although sulphur hexafluoride is long-lived enough to migrate into the stratosphere, its contribution to the depletion of stratospheric ozone is considered minimal.
