Sulphur hexafluoride – SF6

This page features information on sulfur hexafluoride (SF6), appropriate detection means – SF6 gas detector – and respiratory protective equipment (self-contained breathing apparatus and supplied air respirator).

SF6 gas detector and sulfur hexafluoride respiratory protection

Sulfur hexafluoride properties

Sulfur hexafluoride (SF6) is mainly used for electrical applications because of its insulating properties. That’s why it can be used in electrical cabinets, power transformers and capacitors… It is also used as a tracer for detecting gas leaks or monitoring freon-powered cooling systems. It is applied in the medical field as well as a contrasting agent for cardiac and vascular examination.

Sulfur hexafluoride SF6 gas hazards

Sulfur hexafluoride (SF6) is colorless, odorless, heavier than air and is not considered as toxic. However it is suffocating at high concentrations (it replaces oxygen) just like inert gases (also called noble gases). Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture.

SF6 easily hydrolyses into fluorinated compounds in water (thionyl fluoride and hydrogen fluoride) that are extremely toxic and corrosive substances. And it is part of the six gases responsible of greenhouse effects covered by the Kyoto Protocol (one kilogram exhausted in the air equals around 23,000 kg of carbon dioxide (CO2) on the long run).

SF6 gas detector - Sulfur hexafluoride

As sulfur hexafluoride can absolutely not be detected without proper equipment (odorless and colorless gas), only an SF6 detector can accurately measure concentrations of this asphyxiating gas and properly monitor SF6 gas hazards. Thus it is advised to use a fixed or portable sulfur hexafluoride detection device or complete system.
