Asbestos was used in which of the following materials?

Asbestos was used in which of the following materials?

• A. Insulation
• B. Fire proofing
• C. Acoustical tiles
• D. All of the above

Answer: (D)

Asbestos was chosen for its heat resistance and insulation qualities, so it showed up in a variety of building materials. It provided effective insulation for pipes, boilers, and ducts (insulation); it served as a fireproofing agent in sprayed coatings and cementitious products (fireproofing); and it was used in acoustical tiles to improve sound control while adding fire resistance. Because these are all common applications where asbestos was historically used, the option that includes all of these materials is the best choice. Remember that while these properties were why asbestos was used, fibers can become airborne and pose serious health risks, so modern practice relies on safer materials and proper professional handling.
