(IN BRIEF) DNV has launched DNV-RP-A102, a new recommended practice for fire detector mapping that provides robust guidance on the number, placement, and orientation of flame detectors in industrial process facilities. The new standard aims to improve fire detection reliability while avoiding unnecessary system complexity and cost, reinforcing DNV’s leadership in process safety and risk management. Fire detector mapping is a critical safety methodology used to assess whether fires above a defined size can be reliably detected by installed or planned flame detection systems. In developing the new recommended practice, DNV conducted a detailed review of existing fire detector mapping studies and identified recurring limitations in commonly used approaches. DNV-RP-A102 sets out the key technical and methodological requirements for credible three-dimensional fire detector mapping.
