FM Approves First Oxygen Reduction Fire Suppression System

EXPO
September 20, 2025
Factory Mutual (FM) has approved its first inert gas agent fire suppression system for use at FM-insured facilities, marking a significant milestone in fire safety technology. Oxygen reduction systems, which use inert gases like nitrogen or helium to suppress fires by oxygen dilution, offer a water-free alternative for environments where water-based systems are unsuitable, such as data centers and server rooms. This approval means that for the first time, an inert gas agent fire suppression system meets the rigorous performance criteria outlined in FM Approvals Standard 5800, Oxygen Reduction Systems. This development could lead to increased adoption of these systems in commercial and industrial facilities where water incompatibility is a concern. The FM approval may also encourage the development of other inert gas agent suppression systems that meet these performance standards. Exponent's expertise in fire and life safety hazards, risk assessment, and industrial safety positions it to consult on the installation and potential activation of these specialized oxygen reduction systems.
