The selection and use of flammable gas detectors

The selection and use of flammable gas detectors 23 An alarm to warn of a fault condition is vitally important because, if a detector fails, it could falsely indicate a safe condition such as showing a zero reading. There should be no non-detectable fault conditions in the detector, where practicable.

Air-free technique - Wikipedia

The most straightforward type of air-free technique is the use of a glovebox. A glove bag uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed. Inventive ways of accessing items beyond the reach of the gloves exist, such as the use of tongs and strings.
