Abstract: Method for fire and explosion protection in a high-bay warehouse for hazardous chemical substances and, in particular, for Class AI and B VbF [Order on combustible liquids] substances, by reducing the proportion by volume of oxygen in the atmosphere within the warehouse by permanent inertization by means of a barrier gas, in particular nitrogen, to a value of between 12.9 and 13.

Abstract: The present invention relates to a method for the microbiological decontamination of soil, in which1) the contaminated soil is excavated and treated,2) the treated soil is banked up on a prepared subsoil in the form of regeneration clamps, and3) the clamps are provided with oxygen while microbiological degradation of the contaminants takes place.The method comprises mixing the contaminated soil with, preferably contaminated, concrete and/or building rubble, before the mixture is banked up in the form of regeneration clamps, the concrete and/or building rubble having been comminuted before mixing to a particle size of .ltoreq.10 mm, preferably .ltoreq.6 mm.The method according to the invention makes possible, within a short time, decontamination even of soils whose permeability for air and water is only low, and also of soils where the distribution of contaminants is highly inhomogeneous, or where the concentration of contaminants is very high.
