What is a bump test? Is it required? How often is it to be performed? A bump test is a functional test of the gas monitor to ensure that all sensors respond to their target gas and that the alarms will operate prior to using. For example, an H2S sensor is exposed to H2S gas to verify it can respond.
Bump Test Frequency
Based on OSHA's suggestion, the matter of bump test frequency is to be decided by the manufacturer's instructions.
"BW recommends bump testing the sensors before each day’s use to verify your detector is responding to gas. The bump test exposes the detector to a gas concentration that exceeds the alarm set-points to confirm the sensor’s ability to respond. Manually verify that the audible and visual alarms are activated. Calibrate if the readings are not within the specified limits. Taking less than a minute, a functional (bump) test is easy to perform and will ensure that the gas detector is responding and the gas path is not blocked"
Here is an #ANSACGUIDE to ‘IntelliDoX (BW Clips Bump Testing)’ to understand the importance behind bump testing and how to conduct it manually.
