Asbestos Clearance Inspections: What “Clearance” Actually Means
Prepared by Confluence Environmental - independent asbestos and hazardous materials consultants supporting residential, commercial and industrial projects across NSW.
The term “asbestos clearance” is widely used across construction, demolition and remediation projects, yet it remains one of the most misunderstood aspects of asbestos management. Many people assume clearance simply means removal work is finished, or that an area “looks clean”. In practice, proper asbestos clearance inspections are a formal, independent verification process that confirms asbestos removal or remediation works have been completed safely and in accordance with regulatory requirements.
Understanding what clearance actually involves and when it is required is critical for compliance, reoccupation and effective asbestos risk management.
What Is an Asbestos Clearance Inspection?
An asbestos clearance inspection is an assessment undertaken following asbestos removal or asbestos remediation works to confirm that the affected area is safe for reoccupation or continued use. Clearance inspections are carried out by an independent, appropriately qualified assessor and involve a combination of visual inspection and, where required, air monitoring.
The outcome of a clearance inspection is typically documented in a clearance certificate or clearance report that may be relied upon by asset owners, councils, certifiers and regulators. Importantly, clearance is not about whether asbestos was removed it is about whether residual asbestos risk has been adequately controlled following removal works undertaken as part of broader asbestos and hazardous material management.
What Clearance Is and What It Is Not
An asbestos clearance inspection is:
An independent verification process
A check that asbestos removal has been completed in accordance with requirements
A safeguard before reoccupation or recommencement of works
A documented record relied upon by owners, councils and regulators
An asbestos clearance inspection is not:
A sign-off by the asbestos removalist
A purely visual “walk-through”
Optional where clearance is required by law or approval conditions
A substitute for proper asbestos removal controls
Confusion around these distinctions is a common source of compliance risk on asbestos-affected projects.
When Is an Asbestos Clearance Inspection Required?
Clearance inspections are typically required in NSW where friable asbestos removal works have been undertaken or where non-friable asbestos removal exceeds prescribed thresholds under work health and safety legislation. Clearance may also be required where it is specified in development consent conditions, construction certificates or asset owner requirements.
In many cases, clearance is also required by insurers or building owners seeking independent confirmation that asbestos risks have been appropriately addressed. Even where clearance is not strictly mandated, it is often considered best practice particularly for occupied buildings, sensitive environments or projects involving asbestos and hazardous material surveys undertaken earlier in the project lifecycle.
What Does a Clearance Inspection Involve?
While the scope of a clearance inspection is site-specific, it generally involves a risk-based approach proportionate to the type of asbestos removed and the nature of the works.
Visual Inspection
A detailed inspection of the work area and surrounding surfaces is undertaken to confirm that asbestos-containing materials and debris have been removed and that no visible residue remains. This includes inspection of adjacent areas where contamination may have migrated during works.
Assessment of Work Practices
The assessor reviews the condition of the work area following removal, including containment removal, decontamination arrangements and waste handling practices, to confirm the area has been left in a suitable condition for reoccupation or further works.
Air Monitoring (Where Required)
In certain circumstances particularly following friable asbestos removal clearance air monitoring is undertaken to confirm that airborne fibre concentrations are below relevant criteria. This typically involves specialist air monitoring and fibre identification undertaken in accordance with recognised guidance.
Who Can Undertake a Clearance Inspection?
Clearance inspections must be undertaken by an independent person who is appropriately qualified and experienced. Independence is critical the person carrying out the clearance inspection must not have been involved in the asbestos removal works.
For friable asbestos removal, clearance inspections are typically conducted by a Licensed Asbestos Assessor (LAA). For non-friable asbestos, clearance may still require an independent competent person depending on the scope of works, site conditions and regulatory expectations.
Common Issues That Delay Clearance
Delays in clearance inspections commonly arise due to incomplete cleaning of work areas, residual debris in adjacent spaces or services, or poor containment removal practices. Misunderstanding whether air monitoring is required, or a lack of independence between removal and clearance, can also result in failed inspections and repeat visits.
Addressing these issues early particularly through clear scoping and coordination between removal and clearance helps avoid project delays and additional cost.
Why Clearance Matters Beyond Compliance
While asbestos clearance inspections are a regulatory requirement in many cases, their value extends well beyond compliance. Clearance provides confidence for occupants and workers, protection for property owners and duty holders, and documentation relied upon by councils, certifiers and regulators.
In many projects, clearance documentation becomes part of the site’s permanent records and may be referenced during future refurbishment, demolition or property transactions alongside broader hazardous materials documentation.
A Typical Scenario
Following licensed asbestos removal works within a commercial building, a clearance inspection identified residual debris within a ceiling cavity adjacent to the work area. The issue was rectified immediately, and a follow-up inspection confirmed the space was suitable for reoccupation.
Independent clearance prevented potential future exposure and provided assurance to both the building owner and occupants.
Key Takeaways
Clearance is an independent verification process, not a formality. Visual inspection alone is not always sufficient, and independence and competency are essential. Getting clearance right protects people, projects and duty holders, and avoids downstream compliance and liability issues.
Getting the Right Advice
Asbestos clearance inspections play a critical role in ensuring asbestos risks are properly managed and that spaces can be safely reoccupied.
