A system for protecting individuals and property exposed to potential ignition and fires resulting from the release of high-oxygen concentration gas blends from oxygen systems used for breathing assistance. Said system comprises an oxygen storage container and delivery mechanism, said container filled with a blend of above-atmospheric oxygen and inert gases of appropriate composition and capacity to prevent the onset of ignition and fire when discharged and encountering ignition sources and combustibles, yet suitable for breathing by recipients and users of the system. Alternative embodiments can comprise covers over said oxygen containers, filled with materials suitable to prevent the ignition of combustibles encountering the high-oxygen blends from said oxygen containers, when both the blends and materials are dually discharged due to rupture of their respective containers after experiencing an impact.
