Asbestos is a naturally occurring mineral that was widely used in the construction industry in the UK until the 1980s. Asbestos-containing materials (ACMs) are still present in many buildings, including homes, schools, hospitals, factories, and offices. ACMs can pose a serious health risk if they are disturbed or damaged, as they release fibres into the air that can be inhaled into the lungs.

Common ACMs include:

• Asbestos cement products, such as roofing and cladding sheets
• Asbestos insulation, such as pipe lagging and ceiling tiles
• Asbestos floor tiles and adhesives
• Asbestos coatings, such as fireproofing and spray-on insulation

It's important to note that not all ACMs are dangerous, and only a professional asbestos survey can determine the risk level of a particular material.
