Abstract

The method of decontaminating electro-mechanical apparatus from polychlorobyphenyl comprises the steps of: - maintaining the apparatus to be decontaminated submerged in a sealed chamber in vapours of a suitable solvent; and - constantly changing the pressure and temperature of this solvent so as to permit at any time a condensation of the solvent vapours on the surfaces under treatment. The solvent vapours can be produced inside the sealed chamber and, by providing a top condenser, a reflux washing can be obtained, or the vapours can be produced outside the sealed chamber and then injected therein at the required pressure and temperature.
