Bump test every time

02 September 2020

The most common service and calibration recommendation for gas detection instruments is at least once a year.

However, it is less well known that BSIF and other industry bodies recommend bump testing any portable instrument used for worker health and safety protection in a potentially hazardous environment before EVERY use. 

The bump test is a quick and simple check to ensure the instrument’s sensors and alarms are all functioning correctly before it is deployed. A sensor giving a zero reading isn’t necessarily working properly.

Shawcity offers ready-to-use bump test and calibration gas for testing portable and fixed gas detectors. Available in 34, 57 and 103 litre cylinders, we also stock a variety of accessories to help make bump testing as simple as possible.
