Passive Fire System Lifespan: When Do Fire-Rated Products Need Replacing?
June 16, 2025
Passive fire protection is a critical safeguard for your business, property, and people. Experts at IECC know that keeping your building compliant and your people safe means understanding how long your fire-rated products will actually perform under pressure. If you manage or own a building, understanding how fire-rated doors, walls, sealants, and barriers slow the spread of fire is essential to keeping people safe and your asset compliant. But like all building materials, they degrade over time.
In this article, we’ll break down the typical lifespan of passive fire system components, what signs suggest it’s time for replacement, and why regular inspections are essential under fire safety regulations. Let’s ensure your fire protection remains effective and fully compliant. Let’s get started!
A passive fire protection (PFP) system is a crucial component in safeguarding buildings and their occupants against the devastating effects of fire. Unlike active fire protection systems that require a certain action to function (like sprinklers or fire extinguishers), passive fire systems are built into the structure of a building and help contain fires, slow their spread, and protect the structural integrity of the building. Here, we discuss the essential components that make up a passive fire system.
Fire-resistant walls and partitions are integral to compartmentalising a building, thereby containing the spread of fire and smoke. These barriers are constructed using materials that are non-combustible or have a significant resistance to fire, such as gypsum board, concrete, and fire-rated glass. The effectiveness of these walls is determined by their fire-resistance rating, measured in hours, indicating the duration they can withstand fire exposure. They’re commonly used in:
Fire doors and their frames are designed to resist the penetration of fire and smoke, maintaining compartmentalisation during an emergency. These doors are typically made from materials such as steel or timber and are fitted with intumescent seals that expand when exposed to heat, sealing gaps to prevent the passage of fire and smoke. When correctly installed and sealed, they:
Fire and smoke dampers play a role in HVAC systems. Fire dampers are installed in ducts and air transfer openings to prevent the spread of fire by closing automatically upon detection of heat. Smoke dampers, on the other hand, restrict the movement of smoke through the ducts, ensuring that smoke is contained in specific areas and does not spread to other parts of the building.
Ceilings and floors constructed with fire-resistant materials help to contain fire vertically, preventing it from spreading between different levels of a building. Materials such as gypsum, mineral wool, and fire-rated tiles are commonly used in these constructions. The fire-resistance rating of ceilings and floors is crucial in ensuring building occupants have enough time to evacuate safely.
Fire-rated glazing is used in windows, doors, and partitions to allow light and visibility while maintaining fire resistance. This special type of glass is treated to withstand high temperatures and maintain its integrity under fire conditions. Fire-rated glazing is essential in areas where visibility is crucial, such as stairwells and corridors, while still providing a barrier against fire and smoke.
Intumescent coatings are applied to structural elements like steel beams and columns to enhance their fire resistance. When exposed to high temperatures, these coatings expand, forming an insulating layer that protects the structural components from the heat of the fire. This protection is vital in maintaining the structural integrity of a building during a fire, reducing the risk of collapse.
Fire-rated products are designed to perform under extreme conditions, but they’re not built to last forever. As time passes, environmental exposure, building movement, and general wear and tear can all affect their ability to meet their original fire-resistance rating. While there are no universal expiry dates for fire-rated components, compliance with the National Construction Code (NCC) and routine maintenance under AS 1851 are essential for determining when replacement is needed.
Fire doors are essential components in containing fire and smoke, providing safe evacuation routes. As a building manager or owner, you’ll want to schedule regular inspections because even minor wear can mean your doors won’t perform when it matters most.
Fire dampers prevent the spread of fire and smoke through ductwork. However, their effectiveness can diminish if they are not routinely inspected and maintained. The NCC requires regular inspections, typically every 12 months, to ensure they function correctly.
Fire-resistant walls, floors, and ceilings are designed to compartmentalise fire and prevent it from spreading. These structures can last as long as the building itself, provided they are not compromised by renovations, damage, or other structural changes. Their integrity must be maintained to ensure continued performance.
Intumescent coatings expand when exposed to heat, providing an insulating layer that protects structural elements from fire. These coatings can last, although their lifespan can be affected by environmental factors such as moisture and temperature fluctuations.
Passive fire protection products are designed to work silently in the background until a fire breaks out. But when these systems deteriorate or fail due to age, poor maintenance, or building changes, their ability to contain fire is severely compromised. Recognising early warning signs of failure is essential for compliance as well as for protecting lives and property. Here are common signs to watch for:
If you spot cracks around fire doors or wall junctions, it’s a clear sign your passive fire protection could fail under pressure. These may occur due to structural movements, impact damage, or natural wear and tear. Pay close attention to areas where different materials meet, as these are common points of vulnerability. Here’s where to look for these issues:
Warping or distortion in fire-rated elements is more than just a cosmetic issue—it’s a red flag that the product may no longer perform as designed in a fire emergency. These issues interfere with the barrier’s function, reducing its ability to contain fire and smoke. It commonly occurs in:
Corrosion and rust are silent threats to the integrity of passive fire protection systems, especially in coastal, humid, or high-condensation environments. Over time, exposure to moisture, air pollutants, and temperature changes can degrade metal components, weakening their structural strength and functionality during a fire. You will see it in the following places:
You can’t rely on a fire door that won’t latch or close properly, so check for signs like sticking, dragging, or misalignment. Regular testing of door hardware is essential to ensure that all components operate smoothly and reliably. Some signs you need to watch out for include the following:
Unlike some safety measures, passive fire systems require ongoing oversight, not just installation. To remain effective and legally compliant, all fire-rated components must be regularly inspected, tested, and maintained. If you’re responsible for a commercial or multi-residential property, staying on top of passive fire inspections is not optional—it’s your legal and safety duty. Failing to meet these responsibilities can lead to severe consequences, including breaches of the National Construction Code (NCC), violations under AS 1851: Routine Service of Fire Protection Systems and Equipment, and loss of insurance coverage.
The Building Code of Australia (BCA) provides the framework for fire safety standards. Compliance with these standards is mandatory, and they specify the minimum frequency for inspections and maintenance of passive fire protection systems. Typically, the frequency of inspections is determined by the type of building and its specific fire safety features. For instance, high-occupancy buildings may require more frequent checks compared to smaller, low-risk facilities.
While the BCA provides a baseline for inspection frequency, additional guidance can be sought from Australian Standards such as AS 1851, which outlines routine service of fire protection systems and equipment. Generally, passive fire systems should be inspected:
Businesses have a responsibility to maintain passive fire systems in a state that ensures their effectiveness in the event of a fire. This involves regular inspections and timely maintenance and repairs.
Maintaining detailed records of all inspections and maintenance activities is critical. These records should include:
While some inspection tasks can be performed by in-house personnel, engaging qualified fire safety professionals ensures that all aspects of passive fire systems are thoroughly assessed. These professionals are equipped to:
To extend the lifespan of fire-rated products, businesses should adopt proactive maintenance strategies, including:
When passive fire system components show signs of deterioration, building owners face a critical decision: Should you remediate the issue or fully replace the product? Making the right call requires a clear understanding of fire safety regulations, the condition of the component, and the long-term implications of each choice.
Replacement is required when components are too damaged, outdated, or non-compliant to safely perform their function, even after repair. This is especially common in older buildings or after unapproved modifications.
Remediation is the process of repairing or upgrading existing fire-rated components to extend their usable life and maintain compliance. It’s often a cost-effective choice when the issue is minor, isolated, or hasn’t compromised the overall system integrity.
Passive fire protection products don’t last forever, and treating them as permanent fixtures can lead to unexpected failures, compliance breaches, and expensive emergency upgrades. That’s why smart building owners and facility managers plan ahead, factoring lifecycle replacements of passive fire system components into their long-term maintenance budgets.
Lifecycle replacement planning involves forecasting when major components of your passive fire system will need to be replaced and budgeting accordingly. This ensures that your building stays compliant and protected throughout its operational lifespan without the need for reactive, costly emergency work.
Planning for lifecycle replacements is particularly important in strata schemes, commercial buildings, hospitals, educational institutions, and aged care facilities, where regular audits and compliance documentation are mandatory.
In the complex landscape of building safety, ensuring that passive fire protection systems are functioning optimally is not just a regulatory obligation but a business imperative. Regular audits by a qualified passive fire consultant can be the difference between compliance and catastrophe. Regular audits are indispensable to maintaining effective fire safety, and here’s why.
