A bump test is a type of maintenance operation and management procedure used to verify the accuracy and performance of safety equipment, such as gas detectors, respirators, and other protective devices. It is a quick and easy way to check the functionality of the device and ensure it is working properly. The bump test involves exposing the device to a known concentration of the target gas or vapor and then measuring the response of the device. If the device responds correctly, it is considered to be in good working order. If the device does not respond correctly, it may need to be serviced or replaced. Bump tests should be performed regularly to ensure the safety of personnel and equipment.
