An isolation device for one or more ion transport membranes and that has a housing and one or more check valves in communication with one or more passageways extending through the housing to prevent gas flow within the housing and the ion transport membrane(s) upon breakage thereof. Where a lance tube is used with the oxygen transport membrane a second check valve can be used. The check valves, preferably contain spring loaded poppet valves which, though normally open, are capable of resetting themselves into a closed position upon breakage or other failure of the oxygen transport membrane tubes.
