Asbestos, also known as airborne cancer, is a dangerous pollutant that can cause asthma and lung disorders. However, diseases related to asbestos only start after prolonged exposure. In other words, it is impossible for someone to get sick from breathing once or twice near asbestos. Still, it is important to understand that asbestos can stay for 48 to 72 hours in the air. So, you must use an air purifier in the room after using a product that contains asbestos.
