Abstract
The subject of the present invention is a method for removing pollution from a confined environment containing an interior space bounded by a wall, involving the following steps: the confined environment which has a leak is placed in a sealed chamber having for example an inlet for introducing a gas and a pump for pumping a gas and the gas contained in the chamber and the gas contained inside the space are simultaneously pumped through the leak so that the pressure difference across the wall is always below a wall damaging threshold. Another subject of the invention is a related device for removing pollution from a confined environment.
