Asbestos is a naturally occurring mineral fiber, once widely used in building materials and products for its thermal insulating properties and fire resistance.
Intact, undisturbed asbestos-containing materials generally do not pose a health risk. These materials may become hazardous and pose increased risk if they are damaged, disturbed in some manner, or deteriorate over time and release asbestos fibers into building air. A number of building materials and products still in use today contain asbestos. Asbestos remains in use as an acoustic insulator and in thermal insulation, fire proofing, roofing, flooring and other materials.
Ohio Administrative Code (OAC) 3745-20 contains regulations for controlling asbestos emissions from demolition and renovation projects. Ohio's regulations are consistent with U.S. EPA's National Emission Standards for Hazardous Air Pollutants (NESHAP) regarding asbestos.
The regulations require that contractors do several things, such as provide a notification, conduct thorough inspections to determine the presence of asbestos, follow specific work practices, and ensure proper disposal of asbestos-containing material.
