    The importance of monitoring insulating gas leaks and emissions Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere.
