sf6 circuit breaker protection leak ruleThe basics of detecting sulfur hexafluoride guide assists the reader in finding the correct detector to detect SF6 efficiently and safely. While SF 6 is a non toxic gas, it can displace oxygen in the lungs, and cause asphyxia if too much is inhaled. SF 6 gas is approximately five times heavier than air and, if released or leaked in large enough quantity, will accumulate in low lying areas
