  • Health and environmental dangers of SF6-filled switchgear

    SF 6 and by-products are difficult to detect. The US Environmental Protection Agency (EPA) has referred to S 2 F 10 as “the by-product of greatest concern due to its relatively high toxicity,” [10] and has concluded that “SF 6 by-products are difficult to detect chemically under normal working conditions…” SF 6 by-products such as S O F 3 and SF 4 (sulphur tetrafluoride) have a
