Asbestos is a naturally occurring silicate mineral that is used in many different building materials. Due to its natural fire-resistant and insulating properties, it was widely used in the construction industry until the 1970s. However, it was later discovered that asbestos can cause serious health problems if inhaled.

Asbestos can cause various respiratory conditions such as lung cancer, asbestosis, and mesothelioma. Exposure to asbestos can happen in different ways, including through inhaling asbestos fibers that are released into the air when asbestos-containing materials are damaged or torn.
