Asbestos is a notoriously dangerous substance. For decades, it was used without caution or regulation before the devastating effects of exposure were known. Even after the risks were known, asbestos exposure was a huge problem for many people working or living in environments where asbestos was used thanks to poor oversight and noncompliance with safety requirements.
Today, however, people generally understand that asbestos is dangerous and should only be handled with proper protection and by specialists certified in removal. But one question that many people have is when -- or even if -- asbestos should be removed from a building.
