Byproducts of Sulfur Hexafluoride (insulating gas) Use in the Electric

• In the Netherlands in 1989, an accident was reported involving two people who were exposed to unidentified substances resulting from a switchgear equipment failure (Mauthe and Pettersson 1991). The equipment contained SF 6; upon failure, a small amount of powder was observed (likely solid metal fluorides). Both people recovered within two weeks.

The EPA does no t report emission of Sulfr hexafluoride separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and Sulfr hexafluoride. The emissions of HFCs, PFCs, and sf6 gas for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.
