Which of the following is an asbestos-containing material location?

• A. Gaskets
• B. Drywall
• C. Tiles
• D. Glass

Answer: (A)

Asbestos was used in a variety of building components for heat resistance and durability, especially in mechanical sealants. Gaskets are a well-known asbestos-containing location because they’re used in equipment like boilers, pumps, and piping to create tight seals. Over time, if these gaskets degrade or are disturbed, asbestos fibers can be released into the air, posing a health risk.

While some flooring tiles or older drywall products can contain asbestos and certain specialty glass products may have had asbestos in the past, the most consistently recognized asbestos-containing location among the options is the gasket. If you suspect asbestos in any material, don’t disturb it and have a trained professional assess it.
