Asbestos is a mineral that was once widely used in construction and manufacturing, particularly in the 20th century. It is made up of tiny fibers that can be easily inhaled, leading to a range of serious health problems. While asbestos use has declined in recent years, it is still found in many older buildings, including homes, schools, and commercial properties.

Asbestos exposure can lead to a number of health effects, including lung cancer, mesothelioma, and asbestosis. These conditions can take years, if not decades, to manifest, and there is no safe level of asbestos exposure. That's why it's important to take any potential asbestos risk seriously.
