Sulphur Hexafluoride SF6

Hazard pictograms


Non-flammable and non-toxic

Sulfur hexafluoride (SF6) is a gas composed of one sulfur atom and six fluorine atoms, making it a powerful gas. SF6 is known for its exceptional electrical insulating properties and is often used as an insulating gas in electrical and electronic equipment such as transformers, cables, and high-voltage circuit breakers.

SF6 is one of the most potent known greenhouse gases and can remain in the atmosphere for decades. Therefore, it is crucial to ensure that the gas does not leak into the atmosphere, as it displaces oxygen in the air and can be suffocating in high concentrations. The gas is used, among other things, in power plants, and inhaling the gas in large exposures can lead to palpitations, nausea, headaches, and potentially unconsciousness.

To ensure a healthy and safe workplace, it is essential to be aware of the specific risks associated with SF6 and take appropriate measures.
