Asbestos is a naturally occurring mineral that was used extensively in construction and other industries throughout the 20th century. It was prized for its durability, heat resistance, and insulation capabilities. However, it was discovered to be highly carcinogenic and can lead to deadly diseases such as mesothelioma.

Asbestos materials were commonly used in buildings for insulation, fireproofing, and other purposes. Many older buildings still contain asbestos, which presents a significant health risk to occupants and others who come into contact with the material.
