Asbestos is a naturally occurring mineral that was used in building materials until the late 20th century. It was prized for its fire-resistant and insulating properties, which made it a popular choice for construction. However, by the 1970s, it became clear that asbestos was incredibly dangerous to human health.

When asbestos is disturbed, its fibers can become airborne, and when these fibers are inhaled, they can cause serious health problems. Asbestos exposure can lead to lung cancer, asbestosis (a chronic lung condition), and mesothelioma (a rare and deadly cancer that affects the lining of the lungs or abdomen).

Even if your home or workplace was built after asbestos was banned, it's still possible that it contains asbestos. Some products, such as insulation and ceiling tiles, were produced and installed for many years after the dangers of asbestos were known.
