Fire doors are the most inspected and most defected passive fire element in NSW buildings. They are critical to compartmentation — but they are also high-traffic building elements that are subject to constant use, modification and abuse. Understanding what compliance requires and what inspectors look for is essential for building owners, facilities managers and installers.
Why Fire Doors Matter
A fire door is designed to maintain the integrity of a fire compartment boundary — to resist the passage of fire and smoke through an opening for a defined period. When a fire door fails — whether because it was propped open, its seals were damaged, or its hardware was substituted — the entire compartment fails with it.
Applicable Standards
Fire door compliance in NSW is governed by two primary standards: AS 1905.1:2015 (Components for the Protection of Openings in Fire-Resistant Walls — Fire-Resistant Doorsets) specifies the construction and performance requirements for fire door assemblies. AS 1851:2012 Section 17 specifies the routine service and inspection requirements for fire doors in existing buildings.
What Inspectors Check — The Full List
- Door leaf: no damage, warping, holes, splits or unauthorised modifications
- Door frame: secure in opening, no damage, no gaps between frame and wall
- Gaps: top and sides ≤3mm, bottom ≤10mm — confirmed with gauge
- Intumescent seals: present, intact, correct specification, not painted over
- Self-closing device: closes fully and latches from any open position
- Latch/lock: fire-rated latch present, door cannot be held open by latch
- Hinges: minimum 3 fire-rated hinges, no missing screws, no movement
- Hold-open device (if fitted): releases on detection signal, door closes fully
- Door propped open: no wedge, block or other hold-open device in use
- Signage: 'FIRE DOOR KEEP SHUT' sign present, legible, correctly positioned
- Vision panel (if fitted): fire-rated glazing intact, seals undamaged
- FRL marking: fire rating label legible on door leaf or frame
- Hardware: all components fire-rated, no non-rated substitutions
Most Common Fire Door Defects
Based on NSW Fire Brigade inspection data, the top fire door defects are: doors propped open (most common), damaged or painted-over intumescent seals, excessive gaps (particularly at the bottom), non-fire-rated hardware substitutions, and missing or illegible FRL markings.
How Often Must Fire Doors Be Inspected?
AS 1851 Section 17 requires six-monthly routine inspection of all fire doors, with additional annual inspection tasks. This means every fire door in your building must be physically inspected twice per year, with results documented in compliant service records available to your AFSP for AFSS preparation.
Use a Structured Checklist
Our Fire Door Inspection Checklist is aligned to AS 1851 Section 17 and AS 1905.1 — covering all 18 inspection items with Pass/Fail/Defect result fields, photo reference columns and a sign-off block for compliant documentation on every inspection.
