Asbestos is a naturally occurring fibrous mineral that was extensively used in construction materials such as insulation, cement, plaster, and roofing until the late 1990s. While asbestos was once considered a wonder material due to its fire resistance and durability, it is now widely known for its harmful effects on human health.

Exposure to asbestos can cause serious health conditions such as lung cancer, mesothelioma, and asbestosis. The risk of developing an asbestos-related disease depends on several factors, including the type of asbestos, the duration and frequency of exposure, and the person's overall health.

Asbestos surveys are an essential part of managing the risks associated with asbestos. An asbestos survey identifies the presence, location, and condition of any asbestos-containing materials (ACMs) in a property. The survey also assesses the risk of the ACMs and provides recommendations for their management, removal, or encapsulation.
