In which areas of older buildings might asbestos be found?

Asbestos can be found in various components of older buildings, which includes insulation, but also extends to flooring materials, ceiling tiles, fireproofing, and even some types of adhesive. Buildings constructed before the 1980s commonly used asbestos due to its fire-resistant properties and overall durability.

Insulation is a particularly common area where asbestos is encountered, as it was frequently used in pipe insulation, attic insulation, and thermal insulation on boilers and ducts. This widespread use across multiple areas is why C is the correct choice.

The other options are limited in scope. For instance, focusing solely on roofing materials or external walls does not encompass the full range of potential asbestos-containing materials found in older buildings. Likewise, the claim about older furniture being the exclusive area for asbestos overlooks the broader presence of the substance in construction. Understanding where asbestos may be present is critical for health and safety considerations in renovations or demolitions of older structures.
