摘要
Decontamination comprises creating a sealed volume on the outside of the building to be decontaminated, connecting the volume to a vacuum source and dividing the building into a number of relatively small separate and isolated zones (Z) which are decontaminated individually. Decontamination comprises creating a sealed volume on the outside of the building to be decontaminated, connecting the volume to a vacuum source and dividing the building into a number of relatively small separate and isolated zones (Z) which are decontaminated individually. The depression created in the sealed volume is 5-100 Pa, preferably 10-30 Pa, and is created by one or more extraction plants with multi-stage filters (18) and a network of vertical (19) and horizontal rigid pipes connected to the different floors of the building or the parts of it being decontaminated. Each zone is connected to the pipe network by a branch (16) with an air flow regulator (20) controlling the vacuum level.
