Health and environmental dangers of sf6 gas-filled switchgear

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
