Reducing Sulfur Hexafluoride (SF6) Emissions from Gas ...· Reducing Sulfur Hexafluoride (SF6) Emissions from Gas-Insulated Switchgear (310 CMR 7.72) SF6 also lasts in the atmosphere for more than 3,000 years after it is released. As an excellent insulator, SF6 is often found in gas-insulated switchgear (GIS), equipment used in high-voltage electrical systems to control the flow of electrical current.
Myth About SF6 Gas In Electrical Equipment· 3. 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.
