Asbestos is a fibrous material that was widely used in building construction for insulation, fireproofing and sound-proofing purposes until the 1980s. It was a popular building material due to its strength, durability, and resistance to fire, heat and chemicals.

However, it was later discovered that asbestos fibres can cause serious respiratory diseases, such as lung cancer and mesothelioma. Asbestos fibres are microscopic and can easily be inhaled when disturbed, such as during renovation or demolition work.

It is important to note that not all buildings constructed before the 1980s contain asbestos, and not all asbestos-containing materials are immediately dangerous. The risk depends on the type of material and the condition it is in. Nevertheless, if you suspect that your building contains asbestos, it is important to get a professional survey done to assess the risk.
