  • Toxic substances list: sulphur hexafluoride - Canada.ca

    2021-3-15Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable.It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.

    Abstract. The electricity industry has been using sulphur hexafluoride (SF 6) for more than 40 years.SF 6 is an excellent insulating and arc-quenching medium and allows systems to be more powerful and more compact than any other available medium. As well as handling the highest voltages and make/break ratings, SF 6 switchgear is also veryAuthor: Hartmut Knobloch, Klaus Schuler

  • What is SF6? | What is SF6 gas | Coopersenviro.com.au

    What is SF6? Sulfur hexafluoride (SF6) is an odourless, colourless, non-flammable, inorganic, extremely potent greenhouse gas. This compound is formed when sulfur reacts with fluorinated gas that is produced by the electrolysis of anhydrous hydrofluoric acid (HF). It is a hypervalent molecule that has an octahedral geometry comprising of six fluorine atoms that are bound to a sulfur
