A method of removing an article from an enclosure member providing an environment isolated from the ambient environment is particularly applicable in removing infected hospital materials from isolator enclosure members for isolating human patients with acute infectious diseases. Present methods do not satisfactorily prevent spread of infection from the removed material and maintain the integrity of the isolator. In one arrangement of the invention a disposal bag 21 sealed around a port 25 contains a closure bag 28 having a rigid hoop 30 across the disposal bag 21. Heat sealer 33 cuts and seals around the hoop leaving part of closure bag 28 closing the disposal bag 21 and part of bag 28 closing transfer port 25. In another arrangement closure bag 28 slides over a rigid former 34 extending outwardly from the transfer port and cutter sealer 33' cuts and seals portions of the closure bag across the disposal bag by cooperating with a backing member 29' in the closure bag 28. In both arrangements the interior surface of the closure bag 28 is medically clean and after cutting and sealing the surface forms outer surfaces of the disposal bag 21 and transfer port 25.
