    General Information

    What is it?

    Asbestos is a silicate mineral that occurs naturally in the environment. It appears as tiny fibres that, on their own, are not visible to the naked eye. It is these fibres that can make you sick if they are inhaled.

    Asbestos fibres were added to many building materials because they helped to strengthen them, as well as provide other benefits including improved insulation and heat-resistant properties.

    The trick when it comes to remaining safe and healthy in the presence of asbestos is knowing which building materials these fibres were added to, and taking the appropriate care when coming into contact with them.

    There are six different types of asbestos fibres. Three of these are classified specifically as White, Brown and Blue (they have long fancy names too, but let’s keep it simple!), while the other three remain unclassified.

    All of the fibres are potentially life threatening, however, the Blue and Brown varieties are considered more dangerous. This is because their straight, sharp structure makes them more likely to lodge in your lungs if they are inhaled. ht/sharp structure of each makes them more likely to lodge in your lungs once inhaled.

    Non-friable asbestos refers to products that are made up of asbestos fibres bonded with cement, vinyl, resin or other similar material. Non-friable products account for 97% of asbestos products, and as such, they are the ones you are most likely to encounter during home maintenance and renovation projects.

    Common names in the community for products that are classified ‘non-friable’ include:

    • fibro
    • super six
    • bonded asbestos
    • asbestos cement sheets, or AC sheeting.

    Examples of where non-friable asbestos products have been used in homes include (but are not limited to):

    • wall cladding (interior and exterior)
    • roofing
    • eaves
    • fences
    • ridge capping
    • vinyl floor tiles
    • carpet underlay
    • kitchen splashbacks
    • thermal boards around fireplaces
    • backing of electrical boards
    • water or flue pipes.

    Asbestos Info websites.

    The information provided in this website relates mostly to non-friable asbestos products.

    Friable asbestos products are less commonplace, however, they are more hazardous as the fibres are not encased in a bonded form like non-friable products. This means that they are in a better position to be released into the air and inhaled. It presents as a material that can be crumbled, pulverised or reduced to powder by hand pressure (not that we recommend you go around trying to crush suspected materials!). Friable asbestos products are more likely to give off dust, and it is this dust that contains the deadly asbestos fibres.

    Examples of where friable asbestos has been used in homes include (but is not limited to):

    • spray-on insulation or soundproofing
    • asbestos-rope door gaskets in wood stoves
    • insulation on hot water pipes, domestic heaters and stoves (lagging)
    • backing material on floor tiles and vinyl flooring
    • heat-resistant fabrics
    • badly damaged/weathered non-friable asbestos cement products
    • textured paints, decorative ceiling coatings.

    Please note that non-friable products can become friable if they are sufficiently damaged, weathered or otherwise deteriorate.

    History of Asbestos

    The ‘fibro belt’ is the name given to an area in Western Sydney where the use of asbestos-containing products is especially concentrated. The suburbs that form part of the ‘fibro belt’ were largely built in the 1950s and 1960s and had streets where every house was built using fibro sheets reinforced with asbestos.

    The local government areas (and their respective suburbs) that are considered to form part of the ‘fibro belt’ include Canterbury-Bankstown, Blacktown, Fairfield, Cumberland, Liverpool and Wollondilly. The use of asbestos was equally prevalent in the Gosford/Wyong area.

    Large-scale asbestos mining began at the end of the 19th century and has since been explored in many countries around the world including Russia, the United States, China, South Africa, Brazil & Canada.

    Mining in Australia only commenced in the early 1900s with mines eventually operating in New South Wales, Tasmania, South Australia & Western Australia. By far the most infamous asbestos mine was Wittenoom, in the Pilbara region of Western Australia – a town built entirely around the existence of the mine. To date, more than 2000 of the workers and residents of Wittenoom have died from asbestos-related diseases.

    For more information about the history of asbestos worldwide, visit the Asbestos Diseases Foundation website.

    No. Asbestos ceased being mined in Australia in 1983 and was banned from use in building materials in 1989 (although it was used in brake linings and gaskets until recently). Since 31 December 2003, the manufacture, reuse, sale or import of any form of asbestos has been prohibited.

    When to worry?

    We know that there are many people in our community (and all throughout Australia) living in homes that contain some amount of asbestos in a variety of building materials. Just because there is asbestos in your home, doesn’t mean you are not providing a safe home for your family. Asbestos was added to some building materials to strengthen them, and other qualities meant that it actually helped create a really strong, great building material, hence why it was used so widely!

    If your home, and in particular the asbestos-containing products within it, are well maintained, then you are OK.

    You need to be concerned about the asbestos in your home when it becomes damaged (to the extent that the asbestos fibres can be released) or when you are thinking about embarking on a home renovation project. In these cases, it is absolutely essential that you take steps to protect your family.

    For information about how to keep existing products in good condition, visit the Maintenance section.

    For information about what to do when renovating, visit the Renovation Time section.

    Asbestos fibres can make you sick if you inhale them. That’s the only way! If the fibres are safely encased in well-maintained non-friable building products then you are safe. It’s when these products are weathered, damaged or disturbed (as part of a renovation, for instance) that they can be released, inhaled and therefore possibly make you sick in the future.

    According to the Australian Government’s Department of Health & Ageing, there is no safe level of exposure to asbestos fibres; however, the risk of developing an asbestos-related disease increases with the number of fibres a person is exposed to and breathes in during their life. The risk can vary depending on the level and duration of exposure, length of time since the first exposure, and the fibre type. At the end of the day though, there is still no definitive answer as to who will develop an asbestos-related disease. Really, the only way to ensure you are safe is to avoid exposure altogether.

    When asbestos fibres are safely secured in a well-maintained non-friable product, their potential to impact on the health of you and your family is all but removed. Once broken, degraded, or intentionally disturbed as part of a renovation, there is the opportunity for asbestos fibres to escape their encasing and be released into the air. Once this happens they can be inhaled, and this is when you are at risk of developing an asbestos-related disease.

    If an asbestos fibre becomes embedded in your lungs, it can take decades for it to develop into an asbestos-related disease. Theses diseases include, but are not limited to:

    • Asbestosis
    • Lung Cancer
    • Mesothelioma
    • Pleural disease.

    Council Officers are not health experts, so for more specific information about the potential health risks associated with exposure to asbestos fibres, have a look at the information on offer from the following great organisations:

    Australian Asbestos Network
    Mesothelioma
    Lung Foundation of Australia
    Asbestos Diseases Society of Australia
    Bernie Banton Foundation

    For additional support, your GP and their practice staff will be able to assist you with information regarding the risks to your health in relation to asbestos exposure.
