Asbestos is a type of naturally occurring mineral that was extensively used in construction and other industries in the UK in the past. Asbestos is known for its strength, durability, and heat resistance, which made it ideal for use in insulation, fireproofing, and as an additive in building materials such as cement and roofing tiles.

However, asbestos is now known to be a hazardous substance that can cause serious health problems. When asbestos-containing materials (ACMs) are disturbed, they release microscopic fibers into the air that can be inhaled. These fibers can then become trapped in the lungs, leading to long-term health problems.
