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 comprising means of introducing a gas and means of pumping a gas 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 device for removing pollution from a confined environment comprising: a pollution removal chamber able to contain the confined environment, means of introducing a purging gas, means of pumping a gas with variable pumping capacity, means for controlling the pumping rate, means for monitoring the pressure difference between the inside and the outside of the environment. mechanical warping that would damage the wall of the unsealed enclosed environment.
