Asbestos is a naturally occurring mineral that was widely used in construction and industry until the 1980s. Asbestos fibers are strong, flexible, and heat-resistant, making them useful for insulation, fireproofing, and other purposes. However, asbestos has been linked to a range of health problems, including lung cancer, mesothelioma, and asbestosis.

Asbestos is particularly dangerous when it is disturbed or damaged, as this can release fibers into the air. Inhalation of asbestos fibers can lead to serious health problems, particularly if exposure is prolonged or occurs over a long period of time. Asbestos-containing materials (ACMs) are still present in many older buildings, and it is important to identify and manage them properly to protect occupants.
