Asbestos is a naturally occurring mineral that was widely used in building materials before it was banned in 1999. It is a highly dangerous material that can cause serious health conditions such as lung cancer, mesothelioma and asbestosis. The danger lies in the tiny fibres released into the air when asbestos-containing materials are disturbed, which can be easily inhaled into the lungs. Asbestos was commonly used in construction due to its fire-resistant and insulating properties. It can be found in materials such as fibrous cement, textured coatings, insulation, and heating systems.
