Fire and Gas Mapping is the geographical and scenario-based coverage analysis that includes placing of detectors in appropriate locations to achieve best possible detection coverage based on ISA’s performance-based fire and gas technical report (ISA TR84.00.07-2018). The Fire and Gas Mapping assists in the evaluation of flame and gas risks within a process facility and in the reduction of these risks towards an acceptable risk profile by which designs tend towards hazard based approach featuring recognised and quantified hazards.
Reference Definition by Micropack.co.uk: Fire and Gas Mapping clearly defines the risk and the precautions needed to be able to detect fires and gas releases. The methods used allow the designer to optimize the design and achieve the best possible balance between safety and economy. This practice improves safety and reduces operating costs by ensuring that the number of devices used is minimized while the required level of safety is maintained. All responsible fire and gas detector manufacturers should offer this service.
