  • Health and environmental dangers of SF6-filled switchgear

    However, although SF 6 is inert during normal use, highly toxic by-products are produced that pose a serious health threat to the workers who come into contact with them when electrical discharges occur through everyday usage within SF 6-filled equipment [2]. SF 6 has been identified as the most potent and persistent greenhouse gas in existence. In fact, it has a global warming potential approximately 24 000 times greater than carbon dioxide [3].

  • Panel discussion: The pros and cons of using SF6 gas in

    Geoff Slacke: SF 6 handling involves the following scenarios: filing of switchgear, maintenance operations, recycling of used gas, decommissioning of SF 6-filled equipment. SF 6 is one of the heaviest known gases with a density of almost five times that of air. Therefore if released into the atmosphere, the gas tends to accumulate initially in low-lying places where there is no natural ventilation resulting in suffocation.
