2017/8/243. Is SF6 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 is always used in gas tight compartments, greatly minimising leakage.

Operating PrincipleBrief HistoryDesign FeaturesGenerator Circuit BreakersHigh Power TestingIssues Related to SF6 Circuit BreakersComparison with Other TypesCurrent interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectricand arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc is st…See more on en.wikipedia.orgEstimated Reading Time: 12 minsSulfur hexafluoride Wikipedia en.wikipedia.org/wiki/Sulfur_hexafluorideSynthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsSee AlsoFurther ReadingExternal LinksSulfur hexafluoride on Earth exists primarily as a man made industrial gas and has also been found to occur naturally. SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901.
