What belongs on each line of the register
A register line names the area in the language staff already use, then records five things about it. The user group, because a public foyer and a records room carry different risks. The available hours, because a room in constant use cannot receive a task that needs it empty. The surfaces present, because method follows material. The traffic level, because that drives frequency. And the failure mode, meaning what someone would actually complain about if the area were neglected. Five short columns produce a document that survives staff turnover on both sides.
The failure mode column does more work than people expect. In a waiting area it is usually visible litter and marked seating. In a staff kitchen it is odour and bench residue. In a records store it is dust on shelving rather than anything on the floor. Once the failure mode is written down, the task list for that zone almost writes itself, and arguments about whether an area is clean become arguments about a stated standard rather than about impressions formed at different times of day.
