Why Bump Test your Gas Detector?

A 'bump" or "challenge" test of your gas detector will determine whether the unit is responding to gas and thus fit for use. Not only does the bump/challenge test verify the unit will respond to gas, but it also confirms that the detectors audio and visual alarms are in working order meaning that out in the field, you will be able to hear/feel/see when your detector goes into alarm if/when exposed to gas.
