Maintenance is a frequently overlooked requirements in a contained facility. In the example, an entire enclosure containing cleaning and disassembly capabilities was installed in an open area within the facility. Overpacked equipment traveled along access hallways and elevator shafts to be delivered to the maintenance enclosure. Operators accessed the equipment using glovesleeves installed in the enclosure walls, or entered through an airlock fully garbed. The smooth texture of the walls allowed the enclosure to be safely cleaned and collapsed ready for incineration.
To allow for the height of the cleaning room the top of the enclosure was fabricated using grommet. These were attached to the frame using bungee cords which allowed the entire enclosure to be adjustable to meet needs.
The bagging assembly weighed over 100 lbs and was located close to the floor. Removal for cleaning was unfeasible. Cleaning the rig was performed using a tun dish attachment. Because the entire assembly was electropolished it was possible to clean it in place. A large glovebag was used to enclose the entire bagging assembly and the tun dish without breaking the seal of the precision fitted bagging head.
