Author : Fire Proofing | Published On : 14 Sep 2026
Most commercial building owners in Sydney prefer passive fire protection measures because it is designed to stop the soread of fire and toxic fumes without any kind of manual intervention. However, there is one issue with this solution. When these buildings are renovated, remodelled or mechanical upgrades are made to them, this solution often tends to get damaged or neglected. So, it is essential that regular inspections are done to ensure that there are no such problems.
Common Passive Fire Defects
Below are a list of the passive fire defects that are quite common and it is essential that you look out for them:
- If there are gaps around pipes, HVAC ducts, pipes or conduits - especially the ones passing through fire-rated walls then consider it as a defect. To deal with this passive fire Sydney problem the service providers often use silicone, or low-density foam to seal the gap.
- If the intumescent coating used is broken or worn out, then the fire doors are bound to fail the routine check-ups. It may also happen that the perimeter gap between the door frame and the surrounding wall is also unsealed.
- At times it happens that the length of the fire-rated partitions are such that they fall short of the structural floor or the roof soffit above suspended ceilings. As such fire fumes and smokes tend to bypass the compartment boundaries without getting detected.
- Often the required cavity barriers are missing in the concealed horizontal and vertical voids within the walls, raise floors or the exterior facades, which in turn leads to the flame to engulf the unseen structural cavities.
- When unapproved materials like expanding foam is used instead of time tested fire stopping compound systems, the fire barrier itself becomes hazardous. And there is nothing much that you can do besides replacing the entire system.
- During fitouts the intumescent coating applied over beams and load-bearing steel columns often tend to scrape off or gets thinned with the passage of time which leads to premature structural collpase because of the extreme heat of the ongoing fire.
