Asbestos Awareness Training Course Online

Asbestos Awareness Training Course OnlineThis course focuses on highlighting the importance of managing Asbestos in the workplace. Asbestos is a hazardous material that poses a risk to health by inhalation if the asbestos fibres become airborne and people are exposed to these airborne fibres. Exposure to asbestos fibres is known to cause mesothelioma, asbestosis and lung cancer. It is important for employees who may work in buildings that contain asbestos to know where it is likely to be

Asbestos-containing materials were used extensively in Australian buildings and structures, plant and equipment and in ships, trains and motor vehicles during the 1950s, 1960s and 1970s, and some uses, including some friction materials and gaskets, were only discontinued on 31 December 2003.

The well-known adverse health consequences of exposure to airborne asbestos fibres can be prevented if precautions are taken and appropriate procedures are followed. Strong management and control of all asbestos-containing materials (ACM) in the workplace is essential. The risks posed by asbestos vary depending on the nature and condition of the materials and the potential for exposure.

Do you agree that it is a good idea to reduce the risks associated with asbestos in the workplace? Good, let’s start by looking at when and where asbestos has been used in Australia.

What are the historical uses of asbestos?

Asbestos is the fibrous form of mineral silicates belonging to the serpentine and amphibole groups of rock-forming minerals.

The most common form of asbestos used in Australia is crocidolite (blue asbestos), and chrysotile (white asbestos). Crocidolite and chrysotile account for over 95% of asbestos based materials used in Australia. Other mineral forms of asbestos were not widely used.

As a naturally occurring mineral fibre, asbestos is mined and then broken down from mineral clumps into groups of loose fibres.

Asbestos has excellent fire resistance, insulation properties, fibre strength, durability and flexibility. As a result, it was used in more than 3,000 products, including heat-resistant textiles (cloth, padding and board), asbestos cement products (sheets and pipes), special filters for industrial chemicals, thermal insulation products (pipe and boiler insulation), friction materials (clutch plates, brake linings), gaskets, floor tiles, roofing materials, packing materials, paints and protective paper.

A major historical use was as sprayed thermal insulation on steel beams for fire protection. This sprayed or ‘limpet’ asbestos poses the greatest health risk, because of its highly friable nature.

Asbestos-containing materials (ACM) may still be encountered throughout public and private buildings and structures, especially those built between the 1950s and the late 1970s to early 1980s. Some uses of ACM continued until 2003, notably in friction materials (brakes) and gaskets.

What types of asbestos were produced and used in Australia?

Asbestos is the name applied to six naturally occurring minerals that are mined from the earth. The different types of asbestos are: 

Commonly used in Australia

Serpentine

• Chrysotile 

Amphibole

• Amosite
• Crocidolite

Not commonly used in Australia

Actinolite

Anthophyllite      

Tremolite 

In Australia, mostly chrysotile asbestos was mined until 1939. With the commencement of mining at Wittenoom in Western Australia in 1937, crocidolite dominated production until the final closure of this mine in 1966. New South Wales, the first State to mine asbestos, produced the largest tonnages of chrysotile (until 1983), as well as smaller quantities of amphibole (until 1949).

Australian asbestos production and exports declined after the closure of the Wittenoom mine, and imports of chrysotile also started to decline. Consumption peaked in about 1975, at 70,000 tonnes/year.

Australia also imported many manufactured asbestos products, including asbestos cement articles, asbestos yarn, cord and fabric, asbestos joint and millboard, asbestos friction materials and gaskets. The main sources of these products were the United Kingdom, the USA, the Federal Republic of Germany and Japan.

In Australia, the asbestos cement manufacturing industry was responsible for over 60% of all production and 90% of all consumption of asbestos fibre. From about 1940 to the late 1960s all three types of asbestos were used in this industry. The use of crocidolite was gradually phased out from 1967, but amosite was used until the mid-1980s. Much of this industry output remains in service today in the form of ‘fibro’ houses and water and sewerage piping.

Between 1945 and 1954, 70,000 asbestos cement houses were built in New South Wales alone (52% of all the houses built in that State). In Australia as a whole, until the 1960s, 25% of all new housing was clad in asbestos cement. By 1954 Australia was number four in the Western world in gross consumption of asbestos cement products, after the USA, the UK and France, and clearly first on a per capita basis.

When did the national ban on the use of asbestos begin?

On 17 October 2001, the National Health and Safety Commission (NOHSC) declared a prohibition on all uses of chrysotile from 31 December 2003, subject to a very limited range of exemptions.

This prohibition also confirmed earlier prohibitions of the use of amosite and crocidolite asbestos.

Under the National Model Regulations for the Control of Workplace Hazardous Substances the chrysotile asbestos ban prohibits the use (i.e. manufacture, supply, storage, sale, use, re-use, installation and replacement) of chrysotile asbestos except for certain very limited scientific uses.

The prohibition does not extend to the removal of asbestos products in situ at the time prohibition took effect. These in situ asbestos containing materials (ACM) must be appropriately managed to ensure that the risks of exposure to airborne asbestos fibres are minimised.

The ultimate goal is for all workplaces to be free of ACM. Where practicable, consideration should be given to the removal of ACM during renovation, refurbishment, and maintenance, rather than other control measures such as enclosure, encapsulation or sealing. Asbestos products which were in situ on 31 December 2003 may only be replaced by products which do not contain asbestos.
