Claim 0:
1. An apparatus for inerting a working volume in a chemical production plant by flushing with inert gas, wherein the chemical production plant comprises a plant-wide inert gas distribution system comprising pipes for distributing the inert gas and at least one inert gas offtake position which can be connected to a connecting conduit, the apparatus comprising the following constituents and assemblies having a fluid connection with one another:
(a) a gas distributor and a first connecting conduit having a first connecting device, configured to establish a gastight connection between the at least one inert gas offtake position and the gas distributor,
(b) a second connecting conduit having a second connecting device, configured to connect the gas distributor to the working volume to be inerted,
(c) a third connecting conduit having a third connecting device, configured to connect the gas distributor to an offgas disposal apparatus,
wherein the second connecting conduit is connected at the end closest to the working volume to an intermediate piece, wherein the intermediate piece may be connected in a reversibly detachable manner to a counterpiece provided on the working volume, wherein the intermediate piece and the counterpiece in the connected state form a fourth connecting device thereby allowing a flow of inert gas into the working volume, and wherein the second connecting conduit and/or the fourth connecting device comprises a backflow prevention device.
