5 Reasons to Get a Hazardous Materials Audit Before Demolition
Before any demolition or refurbishment work starts, you need to know what hazardous materials are in the building. This is not just good practice. It is a legal requirement under Victorian OHS Regulations.
A hazardous materials audit identifies asbestos, lead paint, synthetic mineral fibres (SMF), polychlorinated biphenyls (PCBs), mould contamination, and other materials that pose health risks during construction work. Here are five reasons to commission one before work begins.
1. It is a legal requirement under Victorian OHS Regulations
Regulation 422 requires a person conducting a business or undertaking (PCBU) to identify asbestos before demolition or refurbishment work commences. This applies to all buildings, regardless of age. The common belief that buildings constructed after 2003 are exempt is wrong. There is no age exemption in Victorian regulations.
For other hazardous materials, general duties under Part 3.1 and Part 4.3 of the OHS Regulations require you to identify health risks before work starts. This includes lead paint, SMF insulation, PCB-containing equipment, and contaminated materials. Failing to conduct an audit exposes you to penalty units that can reach six figures for serious breaches.
2. It protects workers from exposure to carcinogens and toxins
Asbestos fibres cause mesothelioma and lung cancer. Lead exposure damages the nervous system. PCBs are probable carcinogens. Mould generates respiratory irritants and allergens.
Workers breaking into walls, removing ceiling tiles, or disturbing old insulation are at risk if these materials have not been identified and managed. An audit establishes what is present, where it is located, and what control measures are needed before work begins. Without this information, workers are unknowingly exposed to materials that can cause disease decades later.
3. It prevents work stoppages and project delays
If asbestos or other hazardous materials are discovered during demolition or renovation, work must stop immediately. The site needs to be assessed, materials tested, and a management plan developed. Licensed asbestos removalists may need to be engaged. This can add weeks or months to a project timeline. An audit completed before work starts means you know what you are dealing with. Removal or management can be scheduled, costed, and factored into the project plan.
4. It establishes accurate costings for tender and project budgets
Asbestos removal costs vary significantly depending on material type, location, and friability. Lead paint abatement, PCB disposal, and mould remediation each have specific cost structures. An audit provides the information needed to obtain accurate quotes from licensed contractors.
For council projects and large commercial works, an audit allows you to include hazmat removal as a separate line item in tender documents. Contractors can price the work properly rather than inflating their entire bid to cover unknown risks.
5. It creates a defensible record of due diligence
If a worker develops an asbestos-related disease or lead poisoning years after working on your site, the audit report is evidence that you identified hazards and took reasonable steps to manage them.
A NATA-accredited laboratory report, a register of identified materials, and documentation of control measures demonstrate compliance with OHS duties. This matters in WorkCover claims, prosecutions, and civil litigation. Without an audit, you have no documented evidence that hazards were identified or managed.
