"Bump Test" Vs Calibration 

What is a "Bump Test"?

All manufacturers recommend that gas detectors be "bump tested" prior to each use and fully calibrated on a periodic basis.

A bump test is performed in order to confirm that the sensors and alarms are working properly.   The display of a toxic gas or combustible gas detector in fresh air should be zero (0 ppm or 0% LEL) and the display for an Oxygen detector should be 20.9% O2.

Unfortunately, your gas detector may display these same results even if it is not functioning due to sensor failure, damaging exposure to extreme temperatures or shock or if the sensor ports are blocked by clogged filters from dust or water.

A bump test should be performed using calibration gas with component concentrations that are higher than the expected alarm settings to ensure that the sensors and alarms are working properly and that someone has not either intentionally or inadvertently changed or disabled the alarms.

Your company has made an investment in your safety by purchasing personal gas detectors.  Maximize that investment by performing this simple procedure before going about the task at hand.  A few seconds could save your life.

We recommend that you use your calibration gas to perform the bump test and don't waste money on non-conforming calibration gas being sold as "bump gas".
