  • 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.
