Three possible answers, and silence is not one of them
For each restricted room the occupier has to choose between excluding it, having it attended under supervision, or having it attended with specific limits on what is touched. All three are legitimate and each suits different rooms. What causes problems is leaving the question open, because then the answer is decided by an individual on a shift with no context for the decision. Decisions made on a shift are the ones that get remembered wrongly afterwards.
Writing each room into the scope with its arrangement removes the ambiguity permanently. It takes a few lines and it is the difference between a controlled arrangement and an assumption. It also means a change of crew, contractor or facilities manager does not reset the position, which in a technology tenancy is a considerably more valuable property than it first appears. A written list is also something a new facilities manager can pick up immediately.
