Guidelines – Sulphur Hexafluoride Management

insulation gas sulphur hexafluoride (gaz sf6). sf6 gas 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).Get price
