ABSTRACT:
In the event of a failure of a fire prevention or extinguishing system, an inertization method reduces the fire risk in an enclosed protected area, where the oxygen content in the area can be maintained on a control concentration that lies below an operating concentration for a certain time period, so that the emergency operation phase is sufficiently long to prevent the ignition and/or re-ignition of combustible materials therein. The control concentration is maintained for an emergency operation period by a redundant secondary source. Alternatively, the control concentration and the operating concentration, while forming a safety margin, can be lowered so far below the design concentration that in the event of a primary source failure, the growth curve of the oxygen content reaches a limit concentration determined for the area in a predefined period, which is sufficiently long to continue to prevent the ignition and/or re-ignition of the combustible materials.
