  • Sulfur Hexafluoride Leak monitoring for mining

    The importance of monitoring SF 6 leaks and emissions. Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the

    In addition, sulphur hexafluoride is odourless and heavier than air, so that it can accumulate in case of SF 6 leaks in low-lying areas of the gas-insulated switchgear. Without reliable SF 6 monitoring with SF 6 gas sensors there would be a danger of asphyxiation for the workers.
