NSW Fair Trading does not recommend any untrained or unqualified person entering the roof cavity to take a sample of material that could contain loose-fill asbestos insulation.
Loose-fill asbestos cannot be confirmed by a visual inspection as there are other types of insulation that look similar. For this reason, a sample of the material needs to be taken by a licensed asbestos assessor (LAA) and tested by an accredited laboratory to confirm the presence of loose-fill asbestos.
Homeowners are able to arrange their own private sample testing by an LAA and a National Association of Testing Authorities (NATA) accredited laboratory test to detect loose-fill asbestos insulation. SafeWork NSW allows you to search for asbestos and demolition license holders, including LAAs. Enter your search requirements by selecting "licensed asbestos assessor" and the relevant region in NSW.
