Understanding the Asbestos Audit Process: A Step-by-Step Guide

Asbestos was once a popular building material known for its strength, insulation properties, and fire resistance. However, it’s now widely recognized as a significant health hazard. If your property was built before the 1990s, there’s a chance it may contain asbestos. That’s where an asbestos audit becomes essential.

Whether you’re a building manager, business owner, or property developer, understanding the asbestos audit process is critical for health, legal compliance, and peace of mind. This step-by-step guide breaks it down clearly.

What Is an Asbestos Audit?

An asbestos audit—also known as an asbestos survey or asbestos register inspection—is a systematic inspection of a property to locate, identify, and assess any materials that may contain asbestos. It helps building owners manage asbestos safely and comply with local health and safety regulations.

Step-by-Step Guide to the Asbestos Audit Process

1. Pre-Audit Consultation

Before any physical inspection begins, the audit team will:

• Gather background information about the building (construction year, renovation history, existing asbestos records).

• Determine the scope of the audit (e.g., entire building, specific areas, or refurbishment zones).

• Discuss the purpose of the audit (e.g., routine compliance, renovation, demolition).

This helps tailor the audit to your specific needs.

2. Site Inspection and Sampling

A licensed asbestos assessor or hygienist will:

• Conduct a thorough visual inspection of all accessible areas.

• Identify suspected Asbestos Containing Materials (ACMs).

• Take physical samples of materials suspected to contain asbestos, using safe and controlled methods.

Safety is the top priority—sampling is done in a way that prevents disturbance or contamination.

3. Laboratory Analysis

Collected samples are sent to a National Association of Testing Authorities (NATA)-accredited laboratory where:

• Samples are tested under a microscope to confirm the presence and type of asbestos.

• The results are documented in a detailed lab report.

This step is critical to differentiate between harmless materials and dangerous ACMs.

4. Risk Assessment

Each confirmed ACM is assessed for:

• Condition (damaged, intact, sealed)

• Risk of disturbance (based on location and building use)

• Type of asbestos (e.g., friable vs non-friable)

This helps determine how urgently each material needs to be addressed.

5. Asbestos Register and Report

Once the assessment is complete, you’ll receive an Asbestos Audit Report that includes:

• A comprehensive asbestos register (locations, condition, and risk rating of ACMs).

• Photographs and sample data.

• Risk control recommendations (e.g., removal, sealing, regular monitoring).

• A plan for managing asbestos safely moving forward.

This report becomes a legally required document for commercial properties and must be accessible to workers and contractors.

6. Recommendations and Next Steps

Depending on the findings, the audit may recommend:

• Immediate removal of high-risk asbestos.

• Encapsulation or sealing of low-risk materials.

• Ongoing monitoring and re-inspection schedules.

Licensed asbestos removal professionals should be engaged for any abatement work.

Why It Matters

Failing to manage asbestos properly can lead to serious health consequences, including mesothelioma, lung cancer, and asbestosis—not to mention heavy fines for non-compliance.

An asbestos audit helps you:

• Protect occupants and workers

• Meet WHS and regulatory obligations

• Plan safe renovations or demolitions

• Maintain accurate property records

Final Thoughts

An asbestos audit isn’t just a formality—it’s a vital step in protecting people and staying compliant with the law. By following a structured audit process, you can ensure that any asbestos-containing materials on your property are identified, assessed, and managed safely.

Whether you’re managing a commercial property, renovating an older home, or planning a demolition, an asbestos audit gives you the clarity and confidence to move forward safely.
