Whats the issue with asbestos?
Asbestos was a popular material used widely in construction and many other industries. If asbestos fibres are enclosed or tightly bound in a product, for example in asbestos siding or asbestos floor tiles, there are no significant health risks. Asbestos poses health risks only when fibres are present in the air that people breathe. How much asbestos is in a product does not indicate its health risk. If the asbestos fibres are enclosed or tightly bound in a compound, there is no significant health risk. One of the main problems with asbestos came from sprayed or “friable” (easily broken up) amphibole asbestos used in buildings until the 1970s.
