    Testing SF 6 gas for impurities will therefore indicate potential issues with the switchgear. Decomposition products arise during operation of SF 6 gas-insulated switchgear through arcing in moist or impure SF 6 gas. Testing the gas for impurities will therefore indicate potential issues with the switchgear. In addition, while SF 6 containers are designed to be gas-tight to ensure no environmentally hazardous SF 6 gas escapes, it is important to monitor SF 6 gas
