Hydrogen detectors

You can also use a hydrogen detector as a sort of leak detector. I say sort of, because the hydrogen has to reach a certain preset concentration point before the detector indicates its presence. Although you may have a leak, that does not mean it will be at the concentration level needed for detection by the hydrogen detec-...

Can ignite spontaneously and explosively In air at fast flow rates from cylinder or in the event of gas leak. High atmospheric concentrations, e.g. in poorly ventilated epecee, can cause oxygen deficiency, with risk of unconsciousness. Use special hydrogen detector. Ventilate storage area at highest level.

In teleconununication applications, where a large number of lead-acid batteries are assembled in a confined room, exhaust fans should be installed to provide good air ventilation and prevent hydrogen buildup. Hydrogen detectors with a detection limit set at 20% of the lower explosive limit should be installed. Because sparks can ignite hydrogen, electrical sources of arcs, sparks, or flame arrestors should be mounted in explosion-proof metal boxes to eliminate static. 

Just before the combustion the temperature is 590°R (328 K), the air is saturated and a hydrogen detector measures 10 volume percent (mole fraction) hydrogen (see Table 4A-1). 

Some hydrogen detectors may remove the water vapor content of the hydrogen air steam mixture. In this case the measured hydrogen mole fraction (of the dry hydrogen air mixture) will be larger than the value in the original mixture. The correction required to recover the original value is...
