The apparatus for making the above-described method comprises an auxiliary cistern containing a gas mixture of nitrogen and argon. The cistern is connected with a cistern (2) containing the extinguisher and in such a manner, a reserve of an inert gas mixture usable for fire extinguishing is ensured.
