Hazardous Materials Survey
Summary
A hazardous materials survey is an inspection and assessment undertaken to identify hazardous building materials that may pose a risk to health, safety or the environment. These surveys are commonly required prior to refurbishment, demolition or intrusive works and are used to inform safe work planning and regulatory compliance.
Hazardous materials surveys often include the identification of asbestos-containing materials, lead-based paint and other substances that require controlled management.
Definition
A hazardous materials survey is a systematic inspection of a building, structure or site to identify the presence, location and condition of hazardous materials. The survey may involve visual inspection, sampling and laboratory analysis where required.
The purpose of a hazardous materials survey is to provide clear information that allows hazardous materials to be managed, removed or controlled safely during planned works.
Why Hazardous Materials Surveys Matter
From a health and safety perspective, hazardous materials surveys help prevent exposure to substances that can cause serious health effects if disturbed, such as asbestos fibres or lead dust.
From a regulatory perspective, duty holders are required to identify hazards before work commences. Failure to undertake a suitable hazardous materials survey can result in unsafe work practices, regulatory non-compliance and project delays.
From a project delivery perspective, early identification of hazardous materials allows appropriate planning, budgeting and sequencing of works, reducing the risk of unexpected discoveries during construction or demolition.
When a Hazardous Materials Survey Is Typically Required
A hazardous materials survey is commonly required where:
Refurbishment or demolition works are proposed
Intrusive maintenance activities are planned
Development approvals require hazard identification
Older buildings or infrastructure are present
Asbestos or other hazardous materials are suspected
The level of survey detail depends on the nature and extent of proposed works.
Typical Hazardous Materials Identified
Depending on building age and use, a hazardous materials survey may identify:
Asbestos-containing materials
Lead-based paint or lead dust
Synthetic mineral fibres
Polychlorinated biphenyls (PCBs)
Ozone-depleting substances
Other regulated or hazardous building materials
Survey findings are documented clearly to support safe management.
Legislative and Regulatory Context
Hazardous materials surveys are undertaken within work health and safety and environmental protection frameworks.
In New South Wales, WHS legislation requires duty holders to identify hazards that may expose workers or others to health risks. Hazardous materials surveys support compliance with these obligations and are commonly required by councils and asset owners prior to demolition or refurbishment. Similar requirements apply across Australia.
