Asbestos is made up of six naturally occurring silicate minerals (amosite, chrysotile, crocidolite, and the fibrous varieties of tremolite, actinolite, and anthophylite). These asbestos minerals consist of thin, separable fibers arranged parallel to one another. Because they are strong, have the ability to be woven, and are resistant to heat and most chemicals, asbestos fibers were commonly used in manufactured goods such as roofing, insulation, textiles, and transmission parts.

The inhalation of these fibers is what causes mesothelioma and other serious health conditions. The fibers get stuck in the lining of organs, usually the lungs and digestive system, and over time cause inflammation and cellular damage.

Exposure

Common job sites for asbestos exposure include shipyards, auto-manufacturing plants, power plants, chemical plants, oil refineries, and metalworks. Those working in the plumbing, construction, and electrician fields have a high risk of exposure as well because they may be handling products that were made using asbestos.

Another prevailing source of inhalation is the Navy. Though asbestos products were used in many other branches of the US Armed Forces, those who worked in shipyards and vessels are especially at a high risk of developing an asbestos-related disease.

Because of the hazards of asbestos inhalation, all new uses of its have been banned in the United States by the EPA.
