Asbestos is a naturally occurring mineral that has been used in many commercial products due to its heat resistance, electrical insulation, and corrosion resistance properties. There are six types of asbestos, all of which are composed of long and thin fibrous crystals that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibers can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer.
Asbestos exposure occurs when someone inhales or ingests asbestos fibers. Those fibers may then embed in some organ linings and tissues. Over time, this may lead to the development of asbestos-related diseases. Asbestos exposure can occur in many ways, including:
- Occupational exposure: People who work in industries that use asbestos, such as construction, shipbuilding, and manufacturing, are at a higher risk of exposure.
- Environmental exposure: Asbestos fibers can be released into the air from natural deposits or from the breakdown of asbestos-containing materials.
- Secondary exposure: Family members of people who work with asbestos can be exposed to asbestos fibers that are brought home on clothing or equipment.
Asbestos has been used in many products, including insulation, fireproofing materials, automotive brakes, and wallboard materials. Although more than 50 other countries have banned the use of asbestos, its use remains legal in the U.S. after a complicated history of legislation and regulation. The safest strategy to remove asbestos is to hire a professional abatement company.
