GAS DETECTION FEATURE


Figure 3: Emerson’s Incus Ultrasonic Gas Leak Detector captures the sound of pressurised gas leaks and is highly directional.


THE LOGICAL CONCLUSION? So, where does this leave a company creating or evaluating a fire detection and suppression system? Here are a few key thoughts:


The paucity of information on combustible gas detectors in NFPA 72 does not diminish the technologies’ capability or its importance in a comprehensive system.


Without specific instruction, it is all the more important to consult with experts for detector selection and placement.


The lack of clear standards can be an advantage since there are few constraints on technology selection. New detector advances can be adopted without having to wait for the standard to catch up.


Combustible gas detectors should be


measure, and since it has to apply to any conceivable facility from a shopping mall to a hospital to a refinery, it has to be very general. Therefore, when applying it to a chemical


processing plant, for example, there is not much to work with. All an inspector can check is if the detector itself is approved under ANSI/UL 2075, and that it is wired correctly.

There is no comment on the number of detectors deployed, what type of detector, or where they are located. However, subsection 17.10.2.4 says, “The selection and placement of the gas detectors shall be based on an engineering evaluation.” This might prompt an inspector to ask to see said evaluation, with its contents subject to interpretation.


part of any larger fire prevention and suppression system because they are the critical protection layer able to identify when fuel is present but has not yet ignited. Stopping an incident’s escalation at this point makes all the difference.
