Asbestos is a naturally occurring mineral that was commonly used in building materials during the 20th century. It was used for its fire-resistant and insulating properties. However, it was discovered that asbestos can cause serious health problems, such as mesothelioma, lung cancer, and asbestosis. Asbestos is now banned in many countries, but it can still be found in older buildings.

If you suspect that your building may contain asbestos, it is important to have it tested. Asbestos fibers are microscopic, so it is impossible to tell if a material contains asbestos just by looking at it. Asbestos testing involves taking a sample of the material and testing it in a laboratory to determine if it contains asbestos.
