Asbestos is a naturally occurring mineral that was widely used in the construction industry in the past due to its durability and heat-resistant properties. However, it is now known to be a health hazard, with exposure to asbestos fibers potentially leading to serious respiratory diseases such as lung cancer and mesothelioma.

Asbestos can be found in various forms in buildings, including cement, insulation, pipes, and panels. The presence of asbestos in a building can pose a significant risk to the health of its occupants, particularly during refurbishment or demolition work.
