sf6 insulated switchgear leakage GE

Perhaps one of the few exceptions to David's advice is where you have large gas zones such as a gas-insulated busbar entering the substation. The plant I worked at until fairly recently had about 3/4 of a tonne of sf 6 per phase in the gas insulated bus, and that's likely enough to get you in trouble as an asphyxiant. The zones on the switchgear are much smaller.
