Why and How Should Gas Detectors Be Bumped Tested?

What, why, and how are you going to do it? Gas Detectors That Have Been Bumped

The distinction between bump testing and calibration is one of the numerous questions we get here at IGD.

Bump testing is a process for ensuring that a detector's readings are within the predicted tolerance and that the correct warning signals are activated. Bump testing does not require any calibration and is simple to perform with little experience (see video below).

To perform a bump test, all that is required is:

  1. Bump test gas cylinder that can be thrown away
  2. Detector cap, hose, and cylinder regulator

Bump testing a fixed gas detection system is similar to fire alarm system periodic alarm tests. IGD sells bump test kits that can be used for this purpose.


Why Should a Fixed Gas Detection System Be Bumped Tested?

There are several articles on why and how to bump test a portable detector now available, but few discuss fixed systems.

Bump testing a fixed gas detection system follows the same principles. You should be testing your fixed detection systems in the same way that you would a fire system, where a random call point is examined every week or month. For the end user, this provides a variety of advantages:

  1. You can rest assured that the system is detecting the gas in question.
  2. Increases self-assurance.
  3. Allows the site to exercise its Safe Operating Procedures (SOPs) in the same way as the fire system is practised.
  4. Any problems will be detected early on.

Each site will need to design a standard operating procedure (SOP) for bump testing its detectors. We offer end users advice and assistance in developing the most relevant and effective techniques. For example, what is feasible for a laboratory complex will differ from what is feasible for a waste recycling facility or a plant room.

Bump testing is not intended to replace the need for frequent calibration and servicing visits.

IGD Fixed Gas Detection System Bump Test:

The video below provides typical instructions for bump testing IGD gas detection devices with you and your team. The distinction between calibration and bump testing will also be discussed. The video also demonstrates how to acknowledge, silence, and reset alarms. This is from our Online Training Academy, which also includes other "how to" videos and theory courses. Additionally, if you require a bump test kit, you may purchase one here.
