Abstract
The present invention relates to an inerting method for reducing a risk of fire outbreak in an enclosed space as well as a device therefor. A continuous inerting of the enclosed space to spatially-separated zones of the enclosed space is performed as necessary without needing structural separations. At least one inert gas having a gas density (ρGas) which differs from the mean gas density (ρGas) of the ambient atmosphere of the space is introduced into the enclosed space such that a gas stratification including a first gas layer (A) and a second gas layer (B) forms in the enclosed space, wherein the oxygen content in the first gas layer (A) corresponds substantially to the oxygen content of the ambient atmosphere, and wherein the oxygen content in the second gas layer (B) corresponds to a specific, definable oxygen content which is lower than the oxygen content of the ambient atmosphere.
