In any commercial or multi-residential building in WA, your passive fire protection doors are one of the most critical and frequently audited life-safety systems. They are the active component of your passive fire plan—the engineered barriers designed to swing shut, latch tight, and hold back fire and lethal smoke, protecting escape routes and containing a blaze to its point of origin.
Yet, fire doors are consistently one of the most common failure points during an annual fire safety audit. Why? Because they are often treated like regular doors. They get damaged by traffic, illegally modified by tenants, or simply wear out over time.
A failed fire door is an automatic audit defect, resulting in costly rectification notices and leaving your building dangerously non-compliant. As specialists in passive fire protection, Safetytech has inspected thousands of doors across Perth. We know exactly what auditors look for and, more importantly, how to fix these common defects to ensure your building’s passive fire safety is never compromised.
The Critical Role of Fire Doors in Passive Fire Safety
It’s a dangerous misconception to think of a fire door as just a heavy timber or steel door. In the eyes of the National Construction Code (NCC) and Australian Standard AS 1905.1, it is a complete, tested, and certified doorset. Its only job is to provide a certified level of fire resistance (e.g., -/60/30) and smoke-stopping capability when closed and latched.
If a fire door cannot close and latch by itself, it is not a fire door; it is just a hole in a fire wall. Its role in your building’s passive fire safety strategy is completely voided.
Common Failure Points: Why Your Doors Fail Audits
Most passive fire protection doors don’t fail because they were installed incorrectly from the start (though this can happen). They fail because of damage, wear and tear, and illegal modifications that accumulate over time. An auditor’s job is to spot these defects, which are often obvious to the trained eye.
Here are the top reasons your doors will fail an inspection:
Failure 1: Damaged or Missing Seals
Fire doors are fitted with essential seals. If they are damaged or missing, the door fails.
- Intumescent Seals: These are the (often) black strips recessed into the door leaf or frame. When exposed to heat, they expand to many times their original size, sealing the gap and stopping the passage of flames and hot gas. Auditors will fail a door if these seals are painted over (which stops them from activating), damaged, torn, or missing.
- Smoke Seals: These are the (often) brush or rubber-fin seals that provide a barrier against cold smoke—the most dangerous part of a fire’s early stages. If these are worn flat, torn, or impede the door from latching, it’s a defect.
Failure 2: Non-Compliant Hardware (Locks, Latches & Closers)
This is a major failure point. A fire door must be self-closing and self-latching from any position.
- Faulty Closer: The overhead closer (door-return mechanism) is either too weak (doesn’t fully close the door), too strong (slams the door dangerously), or leaking oil and non-functional.
- Non-Latching Hardware: This is critical. The door must have a latch that positively engages in the frame to hold it shut against fire pressure. If someone has installed a standard “passage set” (which just has a non-locking handle) or a roller bolt, the door is non-compliant.
- Illegal Hardware: Auditors constantly find non-rated deadbolts, pad-bolts, or magnetic locks installed by tenants for extra security. These devices prevent the door from closing and latching in an emergency and are a severe compliance breach.
Failure 3: Illegal “Modifications” & Propping
A certified fire door is a tested system. Any modification that hasn’t been approved voids its certification.
- The Door Wedge: The most infamous defect. If an auditor finds a fire door propped open with a wedge, a fire extinguisher, or any other object, it is an instant failure.
- Unapproved Additions: Drilling holes into a fire door’s core compromises its integrity. This includes installing non-rated peepholes, new locks, kick plates, or even screwing in coat hooks or large signs.
Failure 4: Excessive Gaps and Frame Damage
Fire and smoke travel through gaps. AS 1905.1 dictates very strict tolerances for the gaps around a fire doorset.
- The Gaps: An auditor will measure the gap between the door leaf and the frame (at the top and sides) and at the floor. If these gaps are too large (generally over 3mm at the top/sides), the door will fail as fire and smoke can pass through.
- Warped or Damaged Doors: Over time, doors can warp, or the frame can shift, creating these excessive gaps. Worn-out hinges can also cause the door to sag, making it impossible to latch. This is a common issue for many older fire rated doors perth properties contain.
Failure 5: Missing or Illegible Compliance Tags
A fire door must be identifiable. A compliant doorset has a metal tag (usually on the frame or the hinge-side of the door) stating its FRL (e.g., -/60/30), the manufacturer, and the certifier. If this tag is missing, painted over so it’s unreadable, or relates to a standard that is no longer valid, the auditor has no way to verify its rating and must fail it.

Don’t Let Your Doors Be Your Downfall
Your passive fire protection doors are arguably the most important component of your passive fire system because they are the only part designed to move. This makes them the most prone to failure. Don’t wait for an auditor to tell you your building is unsafe.
A propped-open door, a faulty latch, or a missing seal is a direct pathway for fire and smoke, putting your tenants and your property at unacceptable risk.
Contact Safetytech today to schedule a comprehensive inspection of all your fire and smoke doors. Let our experts find and fix the problems before your next audit, ensuring your building is compliant, safe, and secure.
