Talc can sometimes be contaminated with asbestos due to the
proximity of asbestos ore (usually tremolite) in underground talc deposits. By
1973, US federal law required all talc products to be asbestos-free, and today
there is strict quality control in the production of talc products, separating
cosmetic-grade talc (e.g. talcum powder) from industrial-grade talc (often used
in friction products) has largely eliminated this issue for consumers.

Importers should not assume that goods labelled “asbestos
free” are in fact free of asbestos or that testing of goods undertaken overseas
certified “asbestos free” meet Australia’s border requirements. Some countries
can lawfully label or test goods, declaring them asbestos free, if they are
below a certain threshold.

An Australia-wide ban on the use of all types of asbestos
took effect on 31 December 2003. Work Health and Safety (WHS) and environment
laws in all states and territories prohibit the unauthorised supply, transport,
use (including manufacturing), or handling of asbestos.
Artificial Christmas snow, known as flocking, was previously
made with asbestos. It was used as an effect in films including The Wizard of
Oz and department store window displays and it was marketed for use in private
homes under brand names that included "Pure White", "Snow
Drift" and "White Magic".
Loosely-bound asbestos materials are not commonly found in
residential properties and were primarily used in commercial and industrial
settings for fire proofing, sound proofing and insulation. In most cases, glass
fibres have replaced asbestos in today’s insulation products.
Where the testing is carried out overseas, prior to shipping
to Australia, certification must be from an overseas testing laboratory
accredited by the NATA equivalent testing authority in that overseas country.
The local testing authority must be a signatory to a Mutual Recognition
Arrangement (MRA) with NATA. Testing carried out overseas should be undertaken
at, or equivalent to, Australian standards.
Asbestos was once considered to be a very useful mineral
because it is flexible, strong, affordable and can insulate from heat and
electricity. Because of this, it was commonly used in the construction of homes
and buildings.
In 2015, 2 million tonnes of asbestos were mined worldwide.
The Russian Federation was the largest producer with about 55% world share
followed by China (20%), Brazil (15.6%), and Kazakhstan (10.8%).
John Gaskin's report and recommendations were released and
published online in June 2010. As a result of the report, all recommendations
by John Gaskin were considered and incorporated into the Policy for the
management of asbestos containing material in department-owned facilities, the
Asbestos Management Plan in DET Facilities and a proposed training strategy.
Australia was one of the highest users of asbestos per
capita. Products containing asbestos were phased out during the 1980s, a
national ban on asbestos, its importation and all products containing asbestos
came into effect at the end of 2003.
Since 1 January 2008, a bonded asbestos licence has been
required in NSW to remove more than 10m2 of bonded asbestos material. A
licensed bonded asbestos removalist can remove any amount of bonded asbestos
material, and licensing for asbestos removalists is regulated and administered
by WorkCover NSW.
Over 130 employees have already been screened. Of these, 77
workers have been as "medium-to-high priority" based on their
potential exposure to asbestos, and taking into account the nature of their
work and the frequency of access to certain work sites, including the Lawson
sites, a council spokesperson said.

electrician, builder) please go to the Building Standards and Occupational
Licensing website.
A product that contains asbestos fibres that have been mixed
with other materials, such as cement. Non-friable asbestos is commonly found in
buildings in Australia. If non-friable asbestos is damaged or broken, it may
release asbestos fibres into the air.
Mr Tooma's report on the Lawson sites was the first of
several reports to be provided to the council, as part of his broader
investigation.The council has kept the report confidential since receiving it
on February 16, while it seeks legal advice on its release. However, the
Sun-Herald has confirmed the detail of the report and its findings through
multiple sources who have read the report. The fact that contaminated soil was
found at the Lawson sites is not in dispute.
Some archaeologists believe that ancients made shrouds of
asbestos, wherein they burned the bodies of their kings, in order to preserve
only their ashes, and prevent them being mixed with those of wood or other
combustible materials commonly used in funeral pyres. Others assert that the
ancients used asbestos to make perpetual wicks for sepulchral or other lamps. A
famous example is the golden lamp asbestos lychnis, which the sculptor
Callimachus made for the Erechtheion. In more recent centuries, asbestos was
indeed used for this purpose. Although asbestos causes skin to itch upon
contact, ancient literature indicates that it was prescribed for diseases of
the skin, and particularly for the itch. It is possible that they used the term
asbestos for soapstone, because the two terms have often been confused
throughout history.
Asbestos and your healthAsbestos becomes a potential risk to
health if fibres are suspended in air and breathed into the lungs. Breathing
asbestos fibres into the lungs can cause a range of diseases, including
mesothelioma, lung cancer and asbestosis.We are all exposed to low levels of
asbestos in the air we breathe every day. Ambient or background air usually
contains between 10 and 200 fibres every 1,000 litres (or cubic metre) of air.
Whether a person goes on to develop an asbestos-related disease depends on a
range of circumstances or exposure factors; for example, the level and duration
of exposure, length of time since first exposure, the fibre type, and
concurrent exposure to tobacco smoke and other carcinogens.A very small number
of asbestos-related disease cases occur each year in people who have not worked
with asbestos products. The low number of cases makes it difficult to determine
the exact cause of the disease or which exposure to asbestos was the
contributing factor.For further information about the health risks associated
with asbestos in the home environment refer to Asbestos - A guide for
householders and the general public.Asbestos-related diseasesWhen asbestos
fibres are breathed in, they may remain deep within the lungs.
They can lodge in
lung tissue and cause inflammation, scarring and some more serious
asbestos-related diseases, which usually take many years, if not decades, to
develop.The four major asbestos-related diseases are listed below. A person may
show signs of more than one of these diseases.Pleural plaquesareas of white,
smooth, raised scar tissue on the outer lining of the lung, internal chest wall
and diaphragmoften the earliest sign of exposure to asbestosnot everyone who
has been exposed to asbestos develops plaques, possibly because of differences
in their immune response to asbestos fibrespeople with pleural plaques as their
only asbestos related symptom usually have very little impairment of lung
function.Asbestosisa chronic condition caused by inflammation or scarring in
the lungscauses shortness of breath, coughing and permanent lung damagecaused
by heavy, prolonged exposure to asbestos.Lung cancercancerous tumours that
mainly occur in the lining of the tubes leading into the lungs, the smaller
airways or the middle of the lungsrisk of developing lung cancer is increased
in people who also smoke or have a pre-existing lung disease.Mesotheliomaa rare
form of cancer of the tissue that lines the body cavities, particularly the
chest and abdominal cavitiesin Australia, about 90% of all mesothelioma
patients have a confirmed history of significant asbestos exposure.
