Asbestos Roof Removal And Its Importance

    Asbestos

    Because of its properties, which are described as being either ‘non-friable or ‘friable’, asbestos was seen as being very useful for building products.

    Asbestos was once used in Australia in more than 3,000 different products including fibro, flue pipes, drains, roofs, gutters, brakes, clutches and gaskets. Asbestos becomes a health risk when its fibres are released into the air and breathed in. Breathing in asbestos fibres can cause asbestosis, lung cancer and mesothelioma.

    Asbestos is a naturally-occurring mineral and can typically be found in rock, sediment or soil. It has strong fibres that are heat resistant and have good insulating properties. You can’t see asbestos fibres with the naked eye and because they are very light, they can be blown long distances by the wind.

    Friable asbestos is a material containing asbestos that when dry, is in powder form or may be crushed or pulverised into powder form using your hand. This material poses a higher risk of exposing people to airborne asbestos fibres. Friable asbestos was commonly used in industrial applications rather than the home, although loose-fill asbestos has been found in homes in NSW and the ACT, where it was sold as ceiling and wall insulation.

    Non-friable or bonded asbestos products are solid and you can’t crumble them in your hand—the asbestos has been mixed with a bonding compound such as cement. If non-friable asbestos is damaged or degraded it may become friable and will then pose a higher risk of fibre release.
