    Abstract. Sulfur hexafluoride (SF 6) is the insulator gas used in most of equipments handling high and very high voltages.Owing to its high global warming potential, SF 6 has been classified during the Kyoto conference on climate change among the greenhouse gases. Its emission in the atmosphere must therefore be reduced 1.In

    1997-7-26The indoor space in which the SF6 high-voltage equipment is installed is generally tightly sealed. Once the SF6 gas leaks, the air circulation is extremely slow, and the toxic decomposition products are deposited indoors, which is difficult to discharge, which poses a great danger to the workers entering the SF6 switch room.
