Asbestos-containing materials (ACMs) are products that contain asbestos, a naturally occurring mineral once widely used for its heat resistance and insulating properties. Common examples of ACMs include insulation, floor tiles, roofing shingles, and certain types of cement. Due to health risks associated with asbestos exposure, such as lung disease and cancer, the use of these materials has been heavily regulated in many countries. When ACMs are disturbed or damaged, they can release tiny asbestos fibers into the air, posing a risk to human health. Proper handling and removal of ACMs require specialized training and safety measures to prevent exposure. It is essential to identify and manage these materials safely, especially in older buildings where they may still be present.
