A visitor badge is only one moment in a longer control. Tie every non-public visit to an approved sponsor, defined destination and time window, appropriate escort, visible credential, confirmed departure, and reviewable record.

Extinguishers, evacuation policy, employee expectations, hazard selection, monthly visual inspections, annual maintenance, and training must describe the same operating model. A mounted cylinder alone does not establish readiness.
