Byproducts of Sulfur Hexafluoride (sf 6) 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.Get price
