Asbestos testing, also known as asbestos sampling, is the process of identifying and testing the presence of asbestos in building materials. This assessment is vital for health and safety reasons, as it's crucial to determine which properties contain asbestos to take additional precautions when renovating or demolishing such properties. Asbestos can be found in various materials such as insulation, roofing, floor tiles, and some electrical fittings.

Asbestos testing is vital because of its adverse health effects. When asbestos-containing materials (ACMs) are left undisturbed and in good condition, they do not necessarily pose a health risk. But if the ACMs are disturbed or damaged, tiny asbestos fibers can release into the air and be inhaled by anyone who's present in the building. Once inhaled, the fibers can cause lung diseases, many of them life-threatening.
