Asbestos, a naturally occurring mineral fiber, was added to over 3000 products used in the construction of public/commercial buildings and industrial facilities for over a century. When released from these products the invisible, microscopic fibers can enter the body through inhalation or ingestion and settle deep into the respiratory system or digestive tract. The exposure to asbestos fibers in the past, especially by the workers installing or disturbing asbestos-containing materials (ACM) has caused an epidemic of death and disease from asbestosis, lung cancer and mesothelioma. Because of the risk of exposure to asbestos fibers to both workers and the general public, the US EPA and OSHA require that the professionals who identify, plan and carry out renovation or demolition operations that involve ACM be properly trained and certified.
