Asbestos is a naturally occurring mineral fiber that has been widely used in building construction, insulation, and other industrial applications. Due to its durability, heat resistance, and electrical insulation properties, asbestos was used for decades in thousands of products. Though asbestos has been banned in many countries, it is still present in products in older buildings and homes.

Asbestos contains microscopic fibers that can cause serious lung diseases, including asbestosis and mesothelioma - a rare form of cancer. While asbestos is not harmful in its stable form, it can become hazardous when it is disturbed or broken down. This results in fiber release, which can lead to inhalation, ingestion, and subsequent health issues.
