What safety hazard does asbestos present in older buildings?

Asbestos is a well-known hazardous material that was commonly used in construction and insulation in older buildings. When asbestos-containing materials are disturbed or damaged, they can release microscopic fibers into the air. Inhalation of these fibers is associated with serious respiratory issues, including asbestosis, lung cancer, and mesothelioma. These health risks make it crucial for anyone working in or renovating older buildings to handle materials that may contain asbestos with extreme caution, often requiring specialized training and protective measures to prevent exposure.
