Service Penetrations
& Fire Stopping Systems
Understanding how service penetrations affect fire compartmentation and why compliant fire stopping systems are critical throughout buildings across Sydney and NSW.
What Are Service Penetrations?
Openings Through Fire-Rated Barriers
Service penetrations occur where pipes, cables, conduits, ducts and other building services pass through fire-rated walls and floors.
These openings can compromise fire compartmentation if they are not properly protected using compliant fire stopping systems.
Throughout Sydney and NSW, penetration defects are commonly identified during passive fire inspections and remediation projects within existing buildings.

Fire Compartmentation
Why Penetrations Matter
Fire-rated walls and floors are designed to slow the spread of fire and smoke between compartments.
Unprotected penetrations can create pathways allowing fire, smoke and hot gases to spread rapidly throughout a building.
Many penetration defects remain hidden above ceilings, within risers and service shafts until inspections are carried out.
Common Inspection Findings
Typical Penetration Defects
Unsealed Cable Penetrations
Cables passing through fire-rated walls and floors without compliant fire stopping protection.
Oversized Openings
Large openings around services can compromise fire compartmentation performance.
Missing Fire Collars
Plastic pipes penetrating fire-rated barriers without compliant fire collars or wraps.
Incorrect Sealants
Use of non-tested products such as foam or standard silicone instead of compliant fire stopping systems.
Damaged Fire Stopping
Previously installed systems that have been damaged during later service modifications.
Open Service Risers
Unprotected service risers and shafts allowing fire and smoke spread between floors.
Fire Stopping Systems
Common Protection Systems
Different service types and substrates require different fire stopping systems depending on the tested application.
Common passive fire systems include:
- Fire collars
- Fire wraps
- Fire-rated sealants
- Coated batts
- Fire pillows
- Mortar systems
Correct system selection depends on the service type, substrate, fire rating and tested system requirements.
Inspection Workflow
Inspection & Reporting
Passive fire penetration inspections commonly involve reviewing service penetrations throughout a building and identifying defects affecting fire compartmentation.
Inspection findings may include:
- Photographic records
- Defect registers
- Penetration schedules
- Floor plan references
- Compartmentation surveys
BAKKER PFI Australia uses structured inspection workflows and Codexus digital compliance systems to help organise passive fire information throughout buildings across Sydney and NSW.
