Records store shelving and untouched contents in Parramatta buildings

It would be possible to write a nuanced rule about which materials may be handled and which may not, and it would fail immediately. A cleaner has no way to tell a confidential personnel file from a box of superseded catalogues, and no reason to be making that judgement at ten at night. An absolute rule removes the question entirely and is far easier to induct someone into.

It also protects the organisation. If nothing is touched, then nothing can be misplaced, and any question about a missing record can be answered without involving the cleaning arrangement at all. That is worth more to a records custodian than a slightly more thorough clean of a shelf surface, and most will say so if they are asked. Custodians are also the people who have to answer for a record that cannot be found.

Dust control, mainly. Records rooms are entered rarely, generate no traffic soil and hold material that is damaged by damp rather than by dust. The useful work is floors, gangways, shelf edges and uprights, the door area, and reachable ledges where dust settles and then transfers onto boxes when somebody pulls one out. Bottom shelves and the floor beneath them are where most of it accumulates, and where a leak would show first.

Wet methods are used sparingly and away from the shelving, because water and paper records do not mix and a wet floor in a closed room dries slowly. Where the room has a humidity or temperature arrangement, the doors should not be propped open longer than necessary, and the scope should say so rather than leaving it to a crew's convenience. Equipment is also kept clear of shelving rather than parked against a run.

A records room is checked infrequently, so a slow problem can run for a long time. Water marks on a bottom shelf, a ceiling stain above a run, a box that has collapsed, a shelf that is sagging, or evidence of pest activity are all things a crew will see and a custodian will not until they next need something from that bay. By that point the damage has usually progressed well beyond a single box.

Each of those is a short note with a location and a date, sent to the named custodian rather than to whoever arranges cleaning invoices. Cleaning does not treat pests, repair shelving or move affected boxes. What it provides is early notice, which for paper records is often the difference between a recoverable problem and a permanent loss. The note should use the room's own bay references so the location is unambiguous.
