Asbestos is a naturally occurring mineral that was commonly used in construction materials in the past. It was popular due to its heat and fire-resistant properties, strength, and durability. However, exposure to asbestos can cause serious health problems, such as lung cancer, mesothelioma, and asbestosis.

Asbestos-containing materials (ACMs) can be found in numerous products, including cement pipes, roofing, insulation, flooring, and more. Older buildings are more likely to contain asbestos, and it is important to identify and manage any ACMs to protect the health of the building's occupants.
