Abstract
The present invention relates to an inerting method for extinguishing a fire in a closed room in which the oxygen content in the closed room is reduced to a specific inerting level within a given time (x), as well as a device for carrying out the method. In order to achieve the most exacting design possible to the inert gas fire-extinguishing system used during the inerting method, and in particular the most precise dimensioning possible to the inert gas to be provided, while simultaneously adhering to the required fire-fighting stage and re-ignition prevention stage necessary when extinguishing fires, the invention provides for the inerting level to be kept to the re-ignition prevention level within a given regulation range.
