Older Buildings, Older Risks: Passive Fire Protection Challenges and What Maintenance Should Cover
Sydney’s landscape is filled with older apartment blocks and commercial buildings — many built long before current fire safety standards were introduced. While these buildings give neighbourhoods their unique character, they often come with hidden fire protection challenges that can put residents and assets at risk if not properly maintained.
Passive fire protection (PFP) — the systems designed to contain fire and smoke within a building — is one of the most critical yet frequently overlooked areas of building maintenance.
Why Older Buildings Are More Vulnerable
Many older buildings in Sydney’s inner and coastal suburbs were constructed when fire safety codes were less stringent. Over time, renovations, cabling upgrades and plumbing modifications can further weaken fire barriers. Common issues include:
- Damaged or missing fire seals around service penetrations (pipes, conduits, or cables).
- Outdated or poorly maintained fire doors that no longer close or seal properly.
- Gaps or unsealed joints between walls, ceilings and floors.
- Compromised fire-rated walls after trades have installed new services.
Even a small breach in a fire barrier can allow flames and smoke to spread rapidly, reducing evacuation time and increasing the likelihood of property loss.
Key Areas Maintenance Should Cover
Routine inspections and proactive maintenance can significantly reduce risk. Strata managers and building owners should ensure their fire safety maintenance covers:
- Service Penetrations: Every cable, duct and pipe that passes through a fire-rated wall or floor must be correctly sealed with certified fire-stopping materials. Check for unauthorised modifications or patchwork repairs.
- Fire Doors: Inspect regularly for damage, missing seals, or faulty self-closing mechanisms. Fire doors are only effective if they close fully and latch correctly.
- Fire Dampers and Shafts: These control the spread of fire through ventilation systems — ensure they are tested and accessible.
- Fire Collars and Wraps: Especially important in older plumbing systems where materials may have degraded over time.
- Compliant Documentation: Keep updated reports and certification records for all passive fire measures — essential for annual fire safety statements (AFSS).
Staying Ahead of Defect Risk
For strata buildings, it’s crucial to partner with qualified passive fire specialists who understand the challenges of retrofitting older structures. Proactive maintenance not only ensures compliance but also prevents costly rectifications later.
Consider scheduling periodic fire audits — not just the minimum required checks — to identify new penetrations after trades or telecom works.
The Bottom Line
Older Sydney buildings carry charm, but they also carry risk. By addressing service penetrations, maintaining fire doors and ensuring compliant fire seals, building owners and strata managers can stay ahead of defects and protect both people and property. In fire safety, prevention through maintenance isn’t just best practice — it’s a legal and moral responsibility.
