Properties of Sulfr hexafluoride (Sulfur Hexafuoride) GasHandling Nonfaulted sf6 gasHandling Faulted sf6 gasDisposal of Wastea) Toxicitysf 6 is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxygen and cause suffocation. If the normal oxygen content of air is reduced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks shob) Toxicity Of Arc ProductsToxic decomposition products are formed when gaz sf6 gas is subjected to an electric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs.

As one of the group of compounds known as fluorinated gases, sf 6turns out to be the most potent GHG in terms of its global warming potential (GWP). With this realization have come strict measures to help limit the release of gaz sf6 into the atmosphere.

Is Sulfr hexafluoride harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the sf6 gas gas is always used in gas-tight compartments, greatly minimising leakage.Get price
