  • Handling and Use of Sulfur Hexafluoride Gas

    B. Decomposition Gasses and Solid By-Products When exposed to sustained or intense electrical arcs, SF 6 gas decomposes to form sulfur-fluoride gases and metal-fluorides which are toxic. If moisture is present, the decomposition by-products may also include sulfur-oxyfluorides and hydrofluoric and sulfuric acids.

  • SF6 gas as insulating and arc-quenching medium

    Sep 20, 2011 · Arcing causes the decomposition of very small amounts of SF6 gas. The decomposition products react with water, therefore the gas’s moisture content, particularly in the circuit-breaker, is controlled by drying (molecular) filters. Careful evacuation before first gas filling greatly reduces the initial moisture content.
