Overview of Asbestos and Its Risks
Asbestos is a naturally occurring mineral that was widely used in construction and manufacturing due to its heat-resistant properties and durability. There are six different types of asbestos materials, including chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite.
Types of Asbestos Materials
Chrysotile, also known as white asbestos, is the most commonly used type of asbestos and accounts for approximately 95% of asbestos-containing materials used in the United States. Amosite, also known as brown asbestos, was commonly used in insulation products, while crocidolite, also known as blue asbestos, was used in spray-on coatings and pipe insulation.
Health Risks Associated with Asbestos Exposure
Exposure to asbestos can pose serious health risks, including lung cancer, mesothelioma, and asbestosis. Asbestos-related diseases typically develop after prolonged exposure to asbestos-containing materials, which can release microscopic fibers into the air when disturbed.
Lung cancer is the most common form of cancer associated with asbestos exposure, and it typically develops after several years of exposure. Mesothelioma is a rare form of cancer that affects the lining of the lungs, chest, or abdomen, and it is almost exclusively caused by exposure to asbestos. Asbestosis is a chronic lung disease that can cause shortness of breath, coughing, and chest pain.
It is important to note that asbestos-containing materials do not pose a health risk unless they are disturbed or damaged, which can release asbestos fibers into the air. Asbestos-containing materials should only be handled by trained professionals using proper safety equipment and procedures.
