    9 mins readSep 30, 2020“In addition to using an F-Gas Detector, confined spaces with a potential exposure to SF6 should be monitored for their O2 content (remember that if there is less than 20.9% O2, something is displacing the oxygen). Also, the presence of combustible gases should be monitored.
