Environmental health survey in asbestos cement sheets manufacturing industry
Asbestos is a fibrous mineral that was widely used in the manufacture of building materials and other products. In Australia the use of asbestos was phased out in the manufacture of building products through the s and completely banned in The most common product used in residential properties is asbestos cement.
Asbestos cement products pose little risk to health when they are in good condition and undisturbed. However, homeowners must take precautions when removing the products, renovating or doing maintenance work. If you are buying a pre house, ask that asbestos containing products be assessed as part of the building inspection report. Asbestos was added to building products to increase their strength durability, fire resistance and insulation properties.
It is commonly found in:. The manufacture, importation and installation of products containing asbestos was being phased out during the s and was not used in building materials by the end of that decade. However, chrysotile was still found in a number of products, such as brake linings and industrial products until when there was a total ban on the manufacture, use, reuse, import, transport, storage or sale of all forms of asbestos.
If the product is one that could contain asbestos, and was installed prior to when asbestos had stopped being used in building materials you should treat the suspect material as though it does contain asbestos. If you need to verify whether the product is free of asbestos, this can only be done with the use of a microscope.
If you need to confirm the presence of asbestos in a product you will need to contact a National Association of Testing Authorities NATA accredited laboratory external site. The risk of developing an asbestos-related disease from exposure to asbestos products in and around the home is extremely small.
The risk depends on the total number of fibres inhaled, the length of time of exposure and how often you are exposed. Some people have developed an asbestos-related disease after renovating a home containing asbestos. In most of these cases renovations were done when asbestos was a legal product and few precautions were taken. For information on the recommended precautions refer to the information below. Precautions should always be used when removing asbestos products or renovating a house containing asbestos.
All efforts should be made to keep any asbestos products in or around your home in good condition or remove them safely. Just because you have been exposed to asbestos does not mean you will get an asbestos-related disease. In fact it is very unlikely that a single exposure will result in disease. There is no action you need to take if you have been exposed to asbestos, other than making sure that future exposure is minimised.
There is quite a long period 20 to 50 years between exposure and the development of disease, even for people who have had high exposures in the workplace. There is a National Asbestos Exposure Register external site for members of the community who have been exposed to asbestos. The register is for anyone who has had a significant exposure for example, breathing in fine dust from cutting or sawing into a product you later found out contained asbestos.

Historical Version s - view previous versions of standard. More C This specification covers requirements relating to non-asbestos fiber-cement non-pressure sewer pipe, joints, and fittings suitable for use with gravity flow, intended for sewerage and drainage applications from point of use to point of treatment or disposal. The types of pipe shall be shown as type I and type II corresponding to the chemical requirements. The corresponding strength requirements are prescribed. The pipe shall be of laminar construction formed under pressure to a homogeneous structure and cured under natural or accelerated conditions to meet the chemical and physical requirements. Crushing tests, and longitudinal bending tests shall be conducted to meet the requirements prescribed. A hydrostatic pressure test shall be made on an assembly of two sections of pipe properly connected with a coupling to meet the requirements prescribed. This abstract is a brief summary of the referenced standard.
Asbestos is the generic term for a group of naturally occurring fibrous minerals with high tensile strength, flexibility, and resistance to thermal, chemical and electrical conditions. Asbestos fibers are of high-tensile strength, flexible, heat and chemical resistance, and good frictional properties. Cement is the most essential raw material in any kind of construction activity.
InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website. Curing methods for asbestos-cement varied from autoclave, air-drying, to storage under-water! Our page top photograph shows badly broken cement asbestos roofing shingles on a building in upstate New York. Three basic processes are available for curing the asbestos-cement products. These are similar to the procedures used for ordinary concrete materials, however, they are usually maintained under better actual control. The oldest procedure is wet curing. Pipe products, under this system, are frequently stored under water after approximately 7 days of curing in air. Typically, with cement products, the strength of asbestos-cement products increases as time passes. This condition is particularly true in the first year.

Friable asbestos products have been commonly used in commercial and industrial settings since the late s for fireproofing, soundproofing and insulation. Some friable products were also used in houses and may still be found in houses built before In Australia, asbestos cement materials were first manufactured in the s and were commonly used in the manufacture of residential building materials from the mids until the late s. During the s asbestos cement materials were phased out in favour of asbestos-free products. From 31 December , the total ban on manufacture, use, reuse, import, transport, storage or sale of all forms of asbestos came into force.

Benefits of chrysotile products
Asbestos cement , genericized as fibro or fibrolite - short for "fibrous or fibre cement sheet" - and AC sheet , is a building material in which asbestos fibres are used to reinforce thin rigid cement sheets. The material rose to necessity during World War II to make sturdy, inexpensive military housing, and continued to be used as an affordable substitute for many roofing products following the war. Asbestos-cement faced competition with the aluminum alloy , available in large quantities after WWII, and the reemergence of wood clapboard and vinyl siding in the mid to late twentieth century. Asbestos-cement is usually formed into flat or corrugated sheets or piping, but can be molded into any shape wet cement can fit.
When and where was asbestos used?
