What is a key indicator of potential asbestos-containing materials?

The identification of potential asbestos-containing materials is significantly correlated with the age of building materials and systems. Asbestos was widely used in construction prior to the 1980s due to its desirable properties such as fire resistance, thermal insulation, and soundproofing capabilities. Therefore, if materials are found in older buildings, particularly those constructed before regulations limiting or banning the use of asbestos, there is a higher likelihood that they may contain asbestos.

While new construction is less likely to contain asbestos due to stricter regulations, materials with a glossy finish or brightly colored paints are not definitive indicators of asbestos presence, as such characteristics can arise from various other materials and finishes that do not contain asbestos. Thus, focusing on the age of the materials is crucial when assessing the potential for asbestos content.
