Emissions of the powerful greenhouse gas insulating gas are rising

It is difficult to quantify the levels of sf6 gas that enter the atmosphere through leaks from the electricity industry, as well as its other uses such as magnesium and aluminium smelting and military purposes. A recent study suggests that the UK’s use of sf6 gas has risen in recent years, and leakage levels are over 1%.Get price

Health and environmental dangers of sf 6-filled switchgear

Aug 08, 2017 · While SF 6 is regarded as a non-toxic gas, experts agree that it can displace oxygen in the lungs, and therefore cause asphyxia if too much is inhaled. SF 6 gas is approximately five times heavier than air and, if released or leaked in sufficient quantity, tends to accumulate, initially in low-lying areas where there is no natural ventilation, and may cause asphyxiation [12].Get price
