AS 4072.1 is one of the cornerstone Australian Standards governing passive fire protection in buildings. Specifically, it sets out the requirements for how service penetrations (such as pipes, cables, and ducts) and control joints must be treated when they pass through fire-resisting elements. Whether it’s a plumber installing a pipe or a mechanical contractor routing ductwork, any penetration through a fire-rated wall or floor slab has the potential to compromise fire containment unless it is correctly protected.
AS 4072.1 works alongside AS 1530.4, which provides the test methodology used to determine the Fire Resistance Level (FRL) of building elements and firestop systems. Together, these standards form the technical foundation for effective fire compartmentation.
Key Requirements of AS 4072.1
To maintain compliance and preserve the FRL of fire-rated construction, AS 4072.1 requires that:
- All firestopping systems must be tested in accordance with AS 1530.4.
- The penetration must achieve the same FRL as the wall or slab it passes through.
- The annular gap between the service and the substrate must be filled using a tested and certified firestop material.
- Mechanical supports for services must be installed within 300 mm of the penetration to limit movement and prevent damage to the firestop.
Only products that have been tested as a complete system — including the specific service type, substrate, and installation orientation — are permitted. Using individual components with no system-based test evidence is not compliant.
Ceasefire PFP’s Commitment to Compliance
Ceasefire PFP uses only manufacturer-approved firestop systems that have been tested for the exact configuration required. Our field teams are trained to confirm that every penetration matches the test data — from collar type and fastener spacing to wall thickness and pipe size.
To eliminate the risks associated with incorrect assumptions or unverified products, all Ceasefire installations are recorded in a digital passive fire register, including photos and the relevant test references. This ensures full traceability and simplifies review by certifiers and building surveyors.
Common Issues with Non-Compliant Installations
Unfortunately, non-compliant installations are still common across the industry. Typical examples include:
| Issue | Description |
|---|---|
| Incorrect product use | Using a fire collar tested for concrete in a plasterboard wall. |
| Assumed compliance | Relying on previously installed products without checking certification or installation details. |
| Generic materials | Applying generic sealants or wraps without test evidence to AS 1530.4. |
Why Compliance Matters
Compliance with AS 4072.1 is not just a regulatory requirement — it is critical to life safety. Correctly installed firestop systems maintain compartmentation, prevent smoke and flame from spreading between tenancies, and protect building occupants in the event of a fire. For builders and certifiers, it also reduces costly rectifications, prevents project delays, and avoids future liability.
Following completion of a project, Ceasefire PFP provides a comprehensive compliance report, verifying that all works meet the requirements of AS 4072.1 and the National Construction Code (NCC).
Conclusion
AS 4072.1 is a vital standard for anyone involved in the design or installation of passive fire systems. By following its requirements and engaging specialist contractors like Ceasefire PFP, stakeholders can ensure fire safety, certification, and long-term building performance are achieved.
