Asbestos is a naturally occurring mineral that was widely used in construction and manufacturing until the 1980s. Its strength, durability, and resistance to heat and fire made it a popular material for insulation, roofing, and other applications.

However, it was soon discovered that asbestos poses a serious health risk to those who come into contact with it. Inhalation of asbestos fibers can cause a range of respiratory illnesses, including lung cancer, mesothelioma, and asbestosis. These diseases can take up to 40 years to develop and are almost always fatal.

Given these dangers, it is essential to test any materials that may contain asbestos. This is particularly important for older buildings, which are more likely to have been constructed using asbestos-containing materials.
