Asbestos was widely used in the construction industry until the 1980s because of its heat-resistant and insulating properties. However, it's now known to be a highly hazardous substance that can cause serious health problems if inhaled, such as lung cancer and mesothelioma. Asbestos can be found in many older buildings, especially those built before 2000, and it's essential to carry out an asbestos survey to identify any potential risks.
