ASBESTOS RELATED INFORMATION
Asbestos In The Community
Just after the turn of the century, the first wave of asbestos diseases
and deaths occurred in the asbestos mining industry. The second wave attacked
workers in the asbestos manufacturing industry. The third wave affected
former building and construction workers and continues to do so. Now,
due to decaying asbestos products the fourth wave of asbestos diseases,
more subtle and insidious, is stalking a wide range of Australians at
work, at school and in the home. The consequence of the fifth wave is
still yet to come (workers from asbestos removal industry and consequence
of uncontrolled-unsafe removal of asbestos cement products).
Asbestos was often sprayed onto ceilings and walls for a variety of purposes,
i.e. decorative, etc. It was also used as a form of insulation around
the pipes behind radiators or wood-burning stoves. Asbestos was also used
in Vinyl floor tiles and their backings, roofing, eaves, shingles, some
plaster and paint. Many routine repairs, renovation and maintenance activities
- even putting in a new heating system - can disrupt asbestos, releasing
millions of fibres into your home, school or office.
Asbestos cement products such as roofs and cladding contain as much as
11% to 20% of chrysotile and 5% to 10% amphibole asbestos (crocidolite
or amosite). As a result of the continuing exposure to meteorologic influences
such as rain, sunshine, wind and frost, as well as to industrial atmospheric
pollutants, the surface of asbestos cement products corrodes and weathers.
Thus, cement particles and asbestos fibres are released from the surface
and disperse in air and rainwater.
Residential housing and schools were often clad with fibro cement sheeting
(commonly known as fibro) and roofed with corrugated asbestos cement products.
Children who regularly play the whole day in the vicinity of such buildings
are possibly already subjected to a level of exposure to asbestos, which
should not be ignored.
There has been concern for many years that young persons may be more susceptible
to damage by hazardous asbestos fibres. The concern about exposure at
an early age is particularly relevant in the case of carcinogens as critical
organs may be susceptible to cell damage when they are still growing.
Fortunately there is no evidence to date that asbestos has such an effect.
However, if children are exposed to asbestos at an early age, their long
life expectancy increases the probability that they may live long enough
to develop long latent period cancers such as asbestos-induced lung cancer
and mesothelioma. As one eminent doctor commented at the turn of the 20th
century in England, when asked if all girls exposed to asbestos in a yarn
spinning factory would develop asbestosis, he replied, "Yes, if they
live long enough".
The problem of chronic exposure of children to small quantities of airborne
asbestos fibres was high on the agenda at the Third Wave conference (in
New York). One paper at the conference told of asbestos fibres being found
at autopsy in the lung tissue of a full-term stillborn infant that had
never drawn an independent breath.

Home remodelling may be a health hazard
You've been trying to sell your place for months. But given the situation
of the real estate market you've decided to renovate instead. You can't
wait to remove that ugly kitchen lino, those stained ceiling tiles, and
that old asbestos roof. Finally, you are going to install a heating system
that works. Then your neighbour mentions asbestos and the possible health
risk.
The last thing you want to hear is that your kitchen floor could give
you cancer. But if your home was built before the eighties, there is a
good chance that asbestos is present in your home.
During the 50s, 60s, 70s and 80s asbestos was extremely popular within
the building industry because of its attributes to resist heat, flexibility,
and adhesiveness. Architects used to recommend asbestos in building specifications.
For example, asbestos was used to make vinyl tiles and the adhesive backing
on lino flooring. Hot water pipes were often covered with asbestos lagging.
Millboard with asbestos was put behind stoves and radiators for insulation.
Some builders mixed the magic mineral into paint, plaster and Spackle,
or used it to decorate walls and ceilings for the "textured look".
More than a million dwellings were constructed from asbestos cement sheeting
in Australia between 1945 and 1980. Some of those dwellings have been
demolished or had the asbestos roof or cladding removed.
The Asbestos Diseases Society suggests caution. Seek professional advice
before dealing with any asbestos product.
What Does This Mean for Your Renovation?
Don't scrape, cut, rip up or sand down your lino or vinyl floor until
inspected by a recommended professional. The same goes for ceilings. Also
seek advice before commencing removal of asbestos building material.
Before you steam down wallpaper or tear down a wall make sure asbestos
was not mixed into your paint, plaster or spackle or used as insulation
inside the wall.
Never use an ordinary household vacuum cleaner to vacuum dust generated
through the repair or removal of asbestos cement products, as the vacuum
cleaner will turn into a fibre spraying plant.
Contact the Asbestos Diseases
Society on our Toll Free number 1800 646 690 or (08) 9344 4077, or your
local state Department of Occupational Safety & Health (Worksafe)
for advice.
The Asbestos Diseases Society recommends:
Strict adherence to an asbestos-free environment, at home, at school and
at work.
This means a prompt inspection of all pre-1980 buildings. Almost all buildings
of that era contain some form of asbestos as a part of their structure.
Corrective action must be taken wherever the risk arises for asbestos
fibres to escape into the environment. The Australian community must learn
to recognise the potential hazards of asbestos in their homes and acquire
knowledge to deal with it.
