SF6 Gas Hazards and How to Avoid Them - WIKA blog best way to avoid SF 6 gas hazards is to continually monitor gas-insulated equipment for both quantity (to detect leaks) and quality (for current gas conditions). Then, when the gas has dropped below a certain level of purity, technicians can clean it. Here are just a few of WIKA USA's innovative SF 6 gas solutions for greater safety and efficiency:
SF6 Gas testing and SF6 leak imaging/quantification technology· It is then expected that the IEC 60694 standard for common specifications for SF6 (including SF6 gas handling) will be updated ( to IEC62271-1) . "Handling" encompasses the entire spectrum of the management of SF6 gas, including containment of lost gas from leakage, lost gas during maintenance and testing, and reclamation.
