Asbestos is a naturally occurring mineral that was widely used in construction materials in the past. Its fibrous nature made it an ideal material for heat insulation, electrical insulation, and fireproofing. However, in the mid-twentieth century, it was discovered that asbestos can cause severe health issues, leading to its ban in many countries.

Despite its ban, asbestos is still present in many buildings, especially those built before the 1990s. Building materials such as insulation, tiles, roofing, and flooring might contain asbestos fibers. If these materials are disturbed or damaged, the fibers can be released into the air, leading to health issues.
