Two rooms, two arrangements
A clean utility store is a storage room with a hygiene requirement. Floors, shelving structure, benches, sinks and door surfaces are cleaning work, with stock left untouched and equipment kept separate from anything used elsewhere in the premises. It is straightforward provided the method and the equipment separation are written. Sinks and bench edges are the surfaces handled most often. Both need naming in the scope.
A dirty utility room is different. It holds used items and waste streams with specific handling requirements, and part of its contents belongs to a licensed contractor's arrangement rather than to cleaning. The scope has to state which surfaces are included and which containers, streams and items are not touched under any circumstances. Ambiguity in that room is a practical risk rather than a paperwork one.
