Section 12 covers compartment barriers (walls, floors and ceilings with their access hatches and panels), fire-protected structural members, fire-resistant doorsets (hinged, pivoted and horizontal sliding), smoke doors, fire shutters, fire-rated glazing and fire-protected ducts, together with service penetrations and control joints; fire dampers are covered in Section 13. The aim is to identify each barrier and its FRL or smoke requirement and to confirm that openings, penetrations and joints do not compromise it. Elements that cannot be inspected without demolition may be excluded, but roof spaces and voids reachable through hatches, suspended ceilings or raised floors are not excluded; a representative sample of inaccessible areas and a register of what was inspected are recommended. Inspection is carried out against existing compartmentation, structural or marked-up general drawings and schedules showing each item and its fire and smoke requirement (it is not a code compliance audit), and a structural fire inspection uses structural drawings to locate protected members needing repair. High-use and adverse environments get a more rigorous program. Where labels are used they are golden yellow (Y15) with black print, titled 'AS 1851 Service Record', show the service performed (3, 6 or 12), month and year and an equipment ID linked to the summary record, and new labels are placed next to old ones. Frequencies: all passive systems yearly, except fire doors and smoke doors six-monthly (apartment entry doorsets may move to an annual cycle) and sliding fire doors three-monthly.
