The SF6 Gas

SF6 is one of the six greenhouse gases covered by the Kyoto Protocol and Directive 2003/87/EC. Its global warming potential (GWP) is 22,800 times higher than CO2, making it the most powerful greenhouse gas on earth with an atmospheric lifetime of about 3,200 years.

SF6 is mainly used in electrical equipment for its dielectric qualities but is also present in some particle accelerators and electron microscopes.

The use of SF6 is highly regulated in Europe: for producers and users but especially for the personnel who handle it with the obligation to provide proof of a certificate valid for 5 years and issued by an approved body.


Understand the ecological issues related to the use of SF6, know the current legislation and assess the exposure to risk and responsibility of your company.
