Asbestos is a naturally occurring mineral fiber that was commonly used in building materials until the late 1990s before its harmful effects were discovered. It was widely used in construction for its durability, fire resistance, and insulation properties.

Asbestos-containing materials (ACMs) can be found in a variety of building materials, including roofing shingles, ceiling and floor tiles, siding, insulation, and many others. When these materials are damaged or disturbed during renovation or demolition, they can release asbestos fibers into the air, which can be inhaled and cause serious health problems.

Exposure to asbestos can cause lung cancer, mesothelioma, and asbestosis, which can take years to develop and can be fatal. That is why it is essential to identify the presence of asbestos-containing materials through professional testing and take appropriate measures to remove them safely.
