Sulfur hexafluoride circuit breaker - Wikipedia

Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance.

Health and environmental dangers of Sulfr hexafluoride-filled switchgear

SF 6 presented some very significant advantages at the time. For one, it was an excellent replacement for oil-filled circuit breakers and switches that contained what we discovered were harmful polychlorinated biphenyls (PCBs). In addition, SF 6 is not flammable, and so took the threat of explosions and fire off the table as well.
