Asbestos is a naturally occurring fibrous mineral that has been used in over 3,600 different products. It gives strength, fire resistance, and insulating properties to a variety of products. It's also a proven human carcinogen.
When buildings that used asbestos-containing materials are remodeled or demolished, asbestos fibers become airborne. These fibers can remain airborne almost indefinitely, traveling great distances from the point of release.
Asbestos is the most heavily litigated hazardous material that we have to deal with; therefore, it’s the most heavily regulated.
