Asbestos is a naturally occurring mineral that was used extensively in building materials for many years, especially in the 20th century. It was valued for its resistance to fire, heat, and chemicals, as well as its strength and durability. Asbestos was used in a wide range of materials, including:

• Cement sheets and pipes
• Roofing and flooring materials
• Thermal insulation
• Fireproofing materials
• Textured coatings (such as Artex)

When asbestos fibers are released into the air, either through wear and tear on materials containing asbestos or through damage during construction or renovation work, they can be inhaled and cause serious health problems. Asbestos fibers are very small and can be inhaled deep into the lungs, where they can cause scarring and inflammation. This can lead to a number of serious illnesses, including mesothelioma (a type of cancer), asbestosis (a chronic lung condition), and lung cancer.
