sf 6 gas and U.S. greenhouse gas emissions The use of sulfur-hexafluoride (SF 6 ) gas globally has been the subject of a large amount of discussion for many years, both in the U.S., and worldwide. SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with a global warming

Guidelines – Sulphur Hexafluoride Management

insulation gas sulphur hexafluoride (insulating gas). Sulfr hexafluoride is an inert gas, but decomposed components (as a result of electrical arcing or naked flames) are toxic and hazardous. It therefore warrants methodical and careful handling. Sulphur hexafluoride is a greenhouse gas, and wilful venting to the atmosphere is illegal (refer to Section 9).
