Asbestos Definition

Asbestos (Greek a-, "not", sbestos, "extinguishable"): Is a group of fibrous metaphorphic minerals. The name is derived for its historical use in lamp wicks. It was also used in fabrics such as Egyptian burial cloths and Charlemagne's - ('shaa(r)lu me'yn) (King of the Franks and Holy Roman Emperor; conqueror of the Lombards and Saxons (742-814) tablecloth, which according to legend, he threw in the fire to clean. The fibres are typically mixed with cement or woven into fabric or mats. It is used in building for its flame-retardant and insulating properties, its tensile strength, flexibility and resistance to chemicals. Asbestos is now know to be carcinogenic (Causing or tending to cause cancer) and is banned in many countries.
Most asbestos fibres are invisible to the unaided human eye because their size is microscopic.
Confusingly, the modern Greek word means "quicklime".

Asbestos and health

Asbestos can cause health problems when fibres becomeairborne and are inhaled. Once inside the lungs, most fibres are removed by the body's clearance mechanisms.Remaining fibres become trapped in the lungs and, insome individuals, result in serious lung diseases(asbestosis, lung cancer or mesothelioma) that may developyears later. Asbestos fibres can also migrate into the peritoneum (lining of the abdomen), where they may cause peritoneal mesothelioma. Rarely, mesothelioma also develops in other parts of the body (for example, around the heart). Pleural plaques (patches on the outer lining of the lung) also occur from asbestos exposure, but are generally not harmful.
Asbestos-related disease is generally associated withinhaling asbestos over a long time. However, a very small number of people may develop mesothelioma after brief exposure. The reason why this occurs is not known, so it is always important to keep exposure to asbestos fibres as low as possible. For more detailed information about asbestos exposure, related health conditions or diseases, see the en Health document Guidelines for the Management of Asbestos in Non-Occupational Environments'.

Asbestos

Asbestos RoofingAbout Asbestos There are many forms of asbestos - common among these are blue asbestos (crocidolite), white (chrysotile) and brown or grey asbestos (amosite). Other forms of asbestos include anthophyllite which was used mainly in Finland. However tremolite, said to be part of the amphibole asbestos group was used in some commercial talcs in small quantities and is also a contaminant of other asbestos types e.g. chrysotile (white asbestos).

The three most common types of asbestos that were mainly used in a wide range of products are Chrysotile (white asbestos) Crocidolite (blue asbestos) and Amosite (brown or grey asbestos).

Until the late 1960's, the Australian industry used both serpentine (75%) and amphibole (25%) asbestos. Subsequently, the use the chrysotile increased to approximately 95% while blue and grey asbestos declined to 5%. Asbestos is one of the most useful and versatile minerals known to man mainly because of its unique properties, flexibility, tensile strength, insulation (from heat and electricity) and chemical inertness. It is the only natural mineral that can be spun and woven like cotton or wool into useful fibres and fabrics.
More than 3000 asbestos products and their uses have been identified. Most Australian homes contain asbestos products in one form or another. Asbestos products have been used in thousands of commercial and private buildings in Australia. Some other uses of asbestos include fencing, asbestos pipes, thermal insulation, fire proofing, as an additive in paints and sealants, in textiles such as felts and theatre curtains, in gaskets, and in friction products like brake linings and clutches. During the peak building years i.e. 1950's, 1960's and 1970's, asbestos found its way into most public buildings, for example hospitals, schools, libraries, office blocks and factories. Workplaces such as ships' engine rooms and power station were heavily insulated with sprayed limpet asbestos.

Currently, a WorkCover asbestos Licence is required to remove more than 50 square metres and from 1 January 2008 this will be reduced to only 10 square metres.

In compliance with the NSW OHS Regulations 2001 and in accordance with the NSW OHS Act 2000, WorkCover NSW have issued Black Cat Roofing with a Bonded Asbestos Removal Licence

Forms of Asbestos

Can asbestos be reomoved in a safe manner?

Black Cat Roofing has successfully completed the asbestos cement removal and re-roofing of more than 20,000 square meters in the past 18 months.

Different forms of asbestos material, different risk levels.
If asbestos fibres are in a stable material such as bonded in asbestos-cement sheeting such as fibro and in good condition they pose little health risk. However where fibro or other bonded asbestos sheeting is broken, damaged or mishandled fibres can become loose and airborne posing a risk to health. Disturbing or removing it unsafely can create a hazard.
In materials such as pipe lagging and sprayed roof insulation asbestos fibres are not bound in a matrix. High concentrations of fibres are much more likely to be released into the atmosphere when these materials are disturbed or removed.

Here are some examples;

  • Do not use power tools. Asbestos fibres can be released if power tools are used for anything other than the removal of screws.
  • Wear an Australian Standards Protection Level 2 (P2) minimum half face disposable mask and disposable coveralls. These are generally available from hardware suppliers. Non-Australian Standards certified masks should not be used where asbestos is present.
  • Wet sheets down to reduce dust generation and movement.
  • Take the sheets off whole (again, do not use power tools as this may create dust movement).
  • Seal sheets in construction grade plastic. (This should be 200 microns thick.)
  • Contact your Local Council for a licensed disposal point in your area. Waste Service NSW on (02) 9934 7000 will be able to help if you live in the Sydney metropolitan area. Contact the NSW Department of Environment and Conservation Pollution Line on 13 15 55 for information on legally transporting and disposing of asbestos waste.

Should the asbestos be in powder form or can be crumbled, pulverized or reduced to powder by hand pressure when dry, then an asbestos removal contractor with an AS1 Licence is required for its removal.

Asbestos removal: Removal of loose/friable asbestos or amounts of bonded asbestos sheeting greater than 50 square metres must be done by a licensed person.
