摘要： A bag-like contaminant control work module formed from a flexible impervious membrane which is inflated inside of an enclosed workspace to protect workers in the module from contaminants. The workspace, such as in a nuclear power steam generator, has a portal or manway opening into the workspace into which the module is secured by a module passageway. The module includes one or more glove boxes, in which the workers perform their assigned tasks after passing through the passageway and portal. The module includes one or more absolute filters allowing passage of air flow through the module passageway and into the workspace only through the filters. The module may include an auxiliary passageway secured to the outside of the module passageway and also secured in the portal opening and through which items can be passed back and forth to the worker in the glove box from outside the portal. The module is invertible so that it can be pulled out of the workspace trapping all the contaminants therein and disposed of without handling the contaminants.
