Which of the following materials could potentially contain asbestos?

1. Wood siding

2. Blown insulation

3. Vinyl flooring

4. Concrete roofing

The correct answer is: Blown insulation

Blown insulation is a material that has historically been known to contain asbestos, especially in homes and buildings constructed prior to the 1980s when the use of asbestos was more common in building materials. Asbestos was often added to insulation for its fire-resistant properties and ability to improve thermal efficiency. It can be found in a variety of insulation types, including cellulose and fiberglass varieties that were treated with asbestos. While other materials listed may have been associated with asbestos use in certain contexts or may contain other hazardous substances, blown insulation stands out as a material that specifically and commonly contained asbestos in older structures. Understanding this helps highlight the importance of proper inspection and remediation procedures in older buildings to protect against the health risks posed by asbestos exposure.
