Asbestos refers to a group of naturally occurring fibrous minerals that were commonly used in the construction industry in the past. Due to its excellent insulation and fire-resistant properties, asbestos was used in the manufacture of building materials such as roofing materials, ceiling tiles, and insulation.

However, asbestos is now recognized as a health hazard due to its fibrous nature. When asbestos fibers are released into the air, they can be inhaled and cause serious health problems such as lung cancer, mesothelioma, and asbestosis.
