How to maintain Building Fire Integrity and Passive Fire Protection
When it comes to fire safety, Passive Fire Protection and Building Fire Integrity are core functions of any commercial property. Fire integrity are about ensuring the building’s structure can withstand fire long enough to prevent its spread, give people time to evacuate, and allow firefighters to respond appropriately.
Why Building Fire Integrity Checks are so important
Life Safety – Fire-resisting walls, floors, and ceilings compartmentalise a building. If they fail, fire and smoke can spread rapidly. The National Construction Code (NCC) emphasises that structural stability and preventing fire spread are top objectives and critical to the safety of building occupants.
Property Protection – Maintaining fire-rated barriers protects assets by slowing fire growth and fire-induced structural collapse. Passive Fire protection assets also stop the spread of fire to neighbouring buildings – particularly important in adjoining properties which share fire-rated walls.
Regulatory Compliance – In Australia, Passive Fire and Building Fire Integrity inspections are required under AS 1851, and identified defects are typically considered Critical in nature and should be rectified as soon as practical.
Reliable Protection – Fire-rated systems are only as good as their maintenance – trust Compliance Services to carry out your routine maintenance and inspections of all Building Fire Integrity and Passive Fire assets.
Penetrations: Why they are one of the most common defects
One of the biggest threats to fire integrity is penetrations – openings in fire-rated elements made for services like pipes, cables, ducts, or conduits.
If service penetrations are left unsealed or improperly sealed, they can compromise fire resistance, allowing heat, smoke, or fire to spread through what should be a protected barrier. This is common in multi-floor complexes where services run between floors, and a similar theme applies to properties with adjoining fire-rated walls which may have pipework or electrical cables running between them.
To manage this risk, building codes and standards require these penetrations to be sealed with tested fire-stopping systems (collars, fire-rated wraps and sealants, etc.) that maintain the same level of fire resistance as the surrounding barrier.
According to Victorian Building Authority guidance, fire-rated walls or ceilings must have service penetrations correctly treated so that fire and smoke can’t exploit them. Penetrations must also be checked and inspected annually under AS 1851.
Construction Joints: A Common Challenge in Warehouse-Style Buildings
Construction joints (also called control joints) are deliberate gaps between building elements (e.g., slab-to-wall, wall-to-wall) that account for movement or shrinkage. In warehouse-style buildings, where large spans, prefabricated panels, or tilt-up concrete are common, these joints are extremely common.
Under the NCC, construction joints in fire-resisting elements must be protected in a way that mimics a tested fire-resisting assembly. Over time it’s common to see cracks appearing in these sealed joints as the walls experience movement, compromising the fire integrity.
It’s important to regularly check these fire-rated walls and patch any cracks or holes with fire-rated sealant to maintain the fire resisting properties of the wall, which will prevent the spread of fire in an emergency.
Why Regular Fire Integrity Inspections Matter
Even if the building was properly fire-rated when built, that doesn’t guarantee it will stay that way. Over time, penetrations may be modified (e.g., adding new cables), joints may degrade, or fire-stopping materials can deteriorate.
Under AS 1851 Routine Service of Fire Protection Systems, annual inspections of fire-resisting elements (walls, ceilings) and service penetrations are required in most cases.
During inspections, a trained specialist Fire Technician will check seals on penetrations, inspect fire-rated construction joints, and verify the overall fire integrity of the building. Our annual inspections include thorough documentation of the condition of each asset, as well as any defects including photo evidence. This information is then kept on record and used for the Annual Essential Safety Measures Report (AESMR).
Any defects identified during the inspection will be quoted for repairs to return to the intended fire-resisting level or better than originally required.
Key Risks of Neglecting Fire Integrity
Failure to conduct regular fire integrity checks can lead to significant consequences:
Rapid Fire Spread – Unsealed penetrations or poorly treated joints can allow fire and smoke to bypass fire-rated barriers.
Structural Failure – If structural elements lose their original Fire Resisting Level, the building may not maintain stability, risking collapse.
Legal / Regulatory Non-compliance – If fire protection systems don’t meet NCC, or other relevant standards, building owners could face fines or orders.
Insurance / Liability Risks – Deficiencies in passive fire protection may affect insurance outcomes or liability in the event of a fire – for both occupied and neighbouring properties.
Recommendations for Building Owners & Managers
To ensure your building maintains its fire integrity:
Engage a qualified fire-safety professional for fire integrity checks and inspections such as Compliance Services. We will maintain a history of all Building Fire Integrity and Passive Fire Inspections, including outcomes of each check, images of any defects and record of any repairs completed. Each inspection will be scheduled in line with the AS 1851 requirements, ensuring you meet the minimum obligations for fire inspection and services.
Rectify identified issues promptly – reseal penetrations, repair joints, or upgrade materials as needed to maintain the fire resisting properties of the building. Most common defects relating to penetrations and construction joints are considered ‘Critical’ in nature, and should therefore be rectified as soon as practical.
