What is one sign that a building may contain asbestos?

One of the primary indicators that a building may contain asbestos is the presence of insulation, ceiling tiles, or floor tiles manufactured before the 1980s. During this time, asbestos was widely used in construction materials due to its fire-resistant properties and durability. As a result, buildings constructed or renovated with these materials prior to the 1980s have a higher likelihood of containing asbestos.

Asbestos was commonly added to these products to improve their performance, making it crucial to be aware of the age of such materials when assessing the potential for asbestos exposure. The use of insulation, ceiling tiles, or floor tiles from that era is a significant red flag, prompting further investigation or testing to ensure safety.
