In the arrangement for performing a decontamination process by means of a decontamination agent introduced into a first containment (9), the first containment (9) is surrounded by a housing (90) which has a primary inlet (92) for admitting a gas medium into the first containment (9), and a primary outlet (91) for discharging the gas medium from the first containment (9). The primary outlet (91) of the first containment (9) leads to an area (5;51-53) external to the first containment (9) or into the open atmosphere (69) or to a second containment (9). The primary outlet (91) has a gas-technology connection to a first catalyst unit (11) through which the gas medium flows. By means of the at least first catalyst unit (11), the decontamination agent, which is introduced into the first containment (9) during the decontamination process and enters with the gas medium into the area (5;51-53) or open atmosphere (69) or a second containment (9), can be split into non-critical components and degraded to a non-critical residual concentration. In this way, at least during the period of time in which a critical concentration of the decontamination agent is to be found in the first containment (9), the first containment (9) is continuously gas-permeable through the at least first catalyst unit (11) to the area (5;51-53) or to the open atmosphere (69) or to the second containment (9). Further specific features of the catalyst units (11-14) are proposed, which form essential equipment of the arrangement. The overall invention enables an economic operation of containments and thus also a reduced expenditure on shut-off valves for gas-tight sealing of the containments, and of control equipment for the process control of same.
