Asbestos is a hazardous substance that was commonly used in construction materials for many years. It was used in the construction of homes, buildings, and other structures because of its ability to resist heat and flame. However, it was later discovered that asbestos can cause severe health issues, including mesothelioma, lung cancer, and asbestosis.

Asbestos-containing materials can include insulation, roofs, pipes, thermal insulation products, and more. When asbestos-containing materials break down or are disturbed, they can release harmful fibers into the air. That's why it's crucial to ensure asbestos is disposed of in a safe and responsible manner.
