ASBESTOS RELATED INFORMATION
is a generic term applied to some mineral silicates of the serpentine
and amphibole groups, whose characteristic feature is to crystallise in
the late 1960s, the Australian industry used both serpentine (75%) and
amphibole (25%) asbestos. Subsequently, the use of chrysotile increased
to approximately 95% whilst blue and grey asbestos declined to 5%.
deposits of asbestos were discovered in the Ural Mountains in the Soviet,
in the Alps of Northern Italy, Canada, USA, South Africa and Rhodesia.
In Australia, large deposits of crocidolite were found in the North of
Western Australia at Wittenoom Gorge and some deposits of white asbestos
were mined in Northern New South Wales (Barraba and Baryulgil).
USES OF ASBESTOS
More than 3000 asbestos products and their uses have been identified. Most Australian homes contain asbestos products in one form or another. Companies like James Hardie, Colonial Sugar Refinery Limited (CSR) and Wunderlich, manufactured most of the asbestos products that 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.
the peak building years, i.e. 1950s, 1960s and 1970s, 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 stations were heavily insulated with sprayed limpet asbestos.
