Asbestos is a hazardous material that was commonly used in building products throughout the 20th century. At the time, it was regarded as a miracle material due to its heat resistant properties, insulating capability, and durability. However, it was later discovered that asbestos exposure could lead to serious health issues, including lung cancer, mesothelioma, and asbestosis.

Due to the dangers of asbestos, it is no longer used in building products. However, many older buildings still contain asbestos-containing materials, which can be disturbed during renovation or demolition. Asbestos must be carefully removed and disposed of, following strict regulations and guidelines.
