A mistake often encountered in present day cleanroom facilities is the assumption that the garmenting area is not part of the cleanroom. This area is the transition point from the “dirty” to “clean”, which means the section leading into the cleanroom should be at least as clean as the cleanrooom itself.
The design should segregate street clothes from cleanroom garments to minimize contaminate carry-over, particularly along the floor. It must be pointed out that clothing, such as overcoats, boots and rubbers should be left as far from the room entrance as possible. At the entrance there should be a shoe cleaning device and or discardable shoe covers. We also suggest the use of mats to clean to the shoe soles. Mat will pick up gross contaminants from the shoe soles.
Once in the garment room, watches, jewelry and any clothing not to be worn in the cleanroom should be stored on the “dirty” side. The personnel in special garments, then progress to the “clean” side of the room. Mat should be at the entrance of the cleanroom with a waste receptacle placed near it. Due to the “dirty” to “clean” transition, the garment room is a good path to bring items into the cleanroom, either using a pass thru, Liberty’s H100SS or H100PL series, or by carrying them in.
