The invention relates to an oxygen-reducing installation and to a method for operating an oxygen-reducing installation (1). The oxygen-reducing installation (1) has an inert-gas source (2, 3) and a line system (7; 7.1, 7.2, 7.3, 7.4), which is or can be connected to the inert-gas source (2, 3) and to at least one surrounded region (20.1, 20.2) with regard to flow in order to feed gas provided by the inert-gas source (2, 3) to the at least one surrounded region (20.1, 20.2) as needed. According to the invention, a tightness test of at least one region of the line system (7.1, 7.2, 7.3, 7.4) is performed by performing a pressure test of the line region to be tested with regard to tightness by means of at least part of the gas mixture or gas provided by the inert-gas source (2, 3). |
