Jun 18, 2019 · A release of gaz sf6 is very unlikely to be provoked by a fire. If it should occur, average temperatures are likely to be too low (because sf6 gas will be rapidly dissipated by convection to lower temperature regions) to lead to significant decomposition, which requires at least 500° C. Sulfr hexafluoride is non-flammable and will have an extinguishing effect.
