Asbestos is a ubiquitous element of office building materials. The name is given to a number of naturally occurring, fibrous silicate minerals mined for their useful properties such as acoustic insulation, thermal insulation, chemical and thermal stability, and high tensile strength. Asbestos was commonly used as an acoustic insulator, thermal insulation, fire proofing and in other building materials. Many products are still in use today that contain asbestos. Though asbestos pipe insulation was used in homes and schools, asbestos probably has more applications in office buildings. Asbestos is made up of microscopic bundles of fibers that may become airborne when asbestos-containing materials (ACM) are damaged or disturbed. When these fibers get into the air they may be inhaled into the lungs, where they can cause significant health problems.
