What is Asbestos?

Asbestos is a group of naturally occurring mineral fibers valued for their heat resistance, strength, and insulating properties. It was used extensively in construction, manufacturing, and consumer products from the 1930s through the 1980s.

When asbestos-containing materials are disturbed, microscopic fibers become airborne and can be inhaled. These fibers lodge in tissue and cannot be broken down or expelled by the body, leading to chronic inflammation that can eventually cause mesothelioma, lung cancer, and asbestosis.
