Asbestos is a mineral that was used in the past for building materials and insulation. It is very dangerous because it can cause cancer and other illnesses if people are exposed to it. Nowadays, asbestos is not used anymore, but sometimes older buildings or materials may still contain it. If you are in a building that is being renovated or demolished, it is important to make sure that there is no asbestos present to prevent any health risks.
