The invention relates to an inerting arrangement (1) for setting and maintaining predeterminable inerting levels in a protective space (2) to be monitored. The inerting arrangement (1) comprises for this purpose a controllable inert gas system (10, 11, 12) for supplying inert gas, a feed pipe system (20), which is connected to the inert gas system (10, 11, 12) and can be connected to the protective space (2), in order to feed the inert gas supplied by the inert gas system (10, 11, 12) to the protective space (2), and an inert gas system control unit (30) which is designed to control the inert gas system (10, 11, 12) in such a way that an inert gas rate supplied by the inert gas system (10, 11, 12) assumes a value which is suitable for setting and/or maintaining a first predeterminable inerting level in the protective space (2). In order to ensure, even when there is a disruption in the control of the inert gas system (10, 11, 12) or when there is a failure of the inert gas system control unit (30), that the inert gas rate fed to the protective space (2) can in principle be regulated correspondingly such that a second predeterminable inerting level is set and/or maintained in the protective space (2), a correspondingly designed safety device (40, 41, 42, 43) is provided according to the invention. |
