What Is a Bump Test on a Gas Monitor?
A bump test briefly exposes a monitor to known test gas to confirm that sensors respond and alarms operate. It is a functional check, not a complete adjustment of sensor accuracy.
A failed response, blocked inlet, weak alarm, expired gas, damaged tubing, or wrong gas mixture can make the test invalid. Remove failed equipment from service according to plant procedures.
Follow the manufacturer and employer requirements for timing, gas, regulator, accessories, and records. Test-gas cylinders are compressed-gas products; follow the SDS and the plant's storage and handling procedures.
Watch the full test for sensor response, visible and audible alarms, vibration, pump behavior if used, and fault messages. Record the monitor, cylinder, result, date, and tester. Tell the equipment coordinator immediately when a unit fails or the test setup is questionable.
Key point: A bump test confirms basic response before use but does not replace required calibration.
