Asbestos is a naturally-occurring mineral that was widely used in building materials in the past due to its heat-resistant and insulating qualities. However, it was later found to cause serious health problems such as lung cancer, mesothelioma, and asbestosis. Unfortunately, many structures built before the year 2000, including homes, offices, schools, and hospitals, still contain asbestos in some form.

Asbestos can be present in various materials, such as insulation, roofing, flooring, ceiling tiles, pipes, and cement. It is usually harmless when left undisturbed, but when these materials are damaged, drilled, or sawn, they release toxic fibers into the air that can be inhaled and cause harm.
