Asbestos is a naturally occurring mineral that was commonly used in building materials throughout the 20th century. It was popular due to its exceptional strength, durability, and heat resistance. Unfortunately, it was discovered that asbestos exposure could cause serious health problems, including lung cancer, mesothelioma, and asbestosis.

Since the dangers of asbestos have been discovered, its use has been banned in a number of countries around the world. However, many buildings that were constructed before the ban still contain asbestos. This means that many people are still at risk of exposure, especially if they work in industries such as construction or demolition.
