Asbestos is the collective name for several naturally occurring fibrous silicate minerals that can be separated into thin, durable threads. It was once widely used because of its properties: it is heat resistant, withstands acids and other chemicals, and it is a good insulator. Although the use of asbestos has been banned in EU, millions of cubic metres of materials containing asbestos are still in place in existing buildings. Building maintenance workers are at a high risk of coming into contact with asbestos when working on insulations in buildings and industrial installations such as pipes, roofs, walls etc. This E-fact will help building maintenance companies and workers become more aware of the risks of asbestos, and develop the knowledge and skills to avoid exposure to the hazardous fibres.
