We specialise in workplace health and safety solutions for high-risk industries, including asbestos air testing and inspections. Our services help businesses meet occupational health and safety (OHS) regulations in WA while minimising exposure risks—especially those related to airborne contaminants like asbestos—in complex work environments.
Occupational Hygiene Australia (OHAustralia) provides professional asbestos inspections, air monitoring, and occupational hygiene services across Perth and Western Australia. Our experienced team helps businesses identify hazardous materials risks, maintain compliance with workplace health and safety legislation and protect workers from airborne fibre exposure.
We work with clients across the mining, construction, civil, commercial, industrial and manufacturing sectors, delivering practical workplace monitoring and compliance solutions tailored to site requirements.
Following remediation works, our licensed assessor can conduct clearance inspections and issueclearance certificates confirming the area is safe for reoccupation.
Under workplace health and safety legislation, duty holders must identify hazardous materials risks and maintain an up-to-date register where asbestos-containing materials are present.
Occupational Hygiene Australia provides detailed workplace inspections and hygiene assessments for commercial buildings, industrial facilities, mine sites, and construction projects throughout WA.
In addition to hazardous materials assessments, Occupational Hygiene Australia provides a broad range of occupational hygiene monitoring and workplace health and safety services. We also work alongside trusted industry partners for specialist environmental work, remediation projects, radiation services, and medical assessments, allowing us to provide complete project support for our clients.

Many older buildings and houses across WA still contain asbestos-containing materials (ACM), which can be friable or non-friable. Before any renovation, repair or demolition work, the person in control of the site must ensure asbestos is identified and recorded. A qualified assessor conducts an asbestos survey to determine if ACM is present and in what condition. The results are used to create an asbestos register, detailing the location, type, condition and photographs of all identified materials.
In summary, friable asbestos is more hazardous due to its ability to release
fibres easily, while non-friable asbestos is generally safer but can still be
dangerous if compromised.
This register is essential for planning safe work, preventing fibre release and protecting workers and occupants from exposure. Whether it’s a commercial building, residential renovation or demolition project, proper asbestos management is non-negotiable.
Renovating safely starts with knowing what you’re working with.
