Common Passive Fire Defects

Learn about the most common passive fire defects identified during inspections and compliance surveys.

Building Defects

Why Passive Fire Systems Fail

Passive fire systems can become damaged, altered or non-compliant over time due to construction work, poor maintenance or incorrect installations.

Many defects are hidden above ceilings, inside risers, behind walls or within service areas.

Regular inspections help identify these issues before they become significant life safety risks.

Typical Defects

Common Passive Fire Issues

Unsealed penetrations
Missing fire collars
Damaged fire stopping
Oversized openings
Missing smoke seals
Damaged fire doors
Doors wedged open
Untested systems
Damaged compartment walls
Incorrect sealants
Missing documentation
Poor workmanship

Penetration Defects

One Of The Most Common Issues

Service penetrations are one of the most common passive fire defects identified during inspections.

New cables, pipes and services are often added to buildings over time, creating unprotected openings through fire-rated walls and floors.

If these penetrations are not properly sealed using tested systems, fire and smoke can spread rapidly through the building.

Fire Door Defects

Small Issues Can Become Major Risks

Fire doors are often damaged during normal building use and are commonly found with missing smoke seals, excessive gaps or damaged hardware.

Even small defects can reduce the effectiveness of the fire door during a fire event.

Proper inspections and maintenance are essential to maintaining fire compartmentation.

Inspections & Reporting

The Importance Of Regular Surveys

Passive fire inspections help identify defects, document issues and support ongoing compliance management.

Compliance reporting can help building owners understand: what defects exist, what areas are affected, and what rectification work may be required.

This creates a clear pathway toward improving building fire safety and maintaining compliance.
