Asbestos is a naturally occurring mineral that was widely used in building materials in the past. It was popular among builders and manufacturers for its fire-resistant properties, durability, and insulation. However, we now know that asbestos can cause serious health problems, including lung cancer, mesothelioma, and asbestosis.

Asbestos-containing materials (ACMs) are commonly found in older buildings, including homes, offices, and industrial sites. These materials can include insulation, roofing shingles, ceiling tiles, floor tiles, and more.
