Asbestos insulating board (AIB), also known by the trade names Asbestolux and Turnabestos, is an asbestos-containing board formerly used in construction for its fire resistance and insulating properties. [1] These boards were commonly used in the United Kingdom from the 1950s until production ended in 1980.
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
The Koegas mine was a crocidolite (blue asbestos) mine in Northern Cape, South Africa. It lies near to the town of Prieska and drew much of its workforce from there and Griquatown; though significant proportions also came from Botswana, Zimbabwe and Malawi. The mine was opened by Cape Asbestos Company Limited in 1893. Its small-scale operations ...
Asbestos cement, genericized as fibro, fibrolite (short for "fibrous (or fibre) cement sheet"; but different from the natural mineral fibrolite), or AC sheet, is a composite building material consisting of cement and asbestos fibres pressed into thin rigid sheets and other shapes.
Chrysotile asbestos, also known as white asbestos, was first commercially mined at the Havelock Mine in 1939 [3] after detailed prospecting from 1928 to 1929. [4] Mining and processing methods included dry grinding, which, together with the crushing, sorting, grinding and bagging of the ore, generated substantial dust at the mine site and in the surrounding area.
Often referred to as blue asbestos, it is considered the most hazardous. The association between blue asbestos and mesothelioma was established by J. C. Wagner, C. A. Sleggs, and P. Marchand by 1960. [7] Crocidolite asbestos was mined in South Africa, Bolivia, and Wittenoom, Western Australia.
In 1976 it established a scaffolding division [5] and in the late 1970s it developed asbestos-free products such that by 1980 it had become the world's foremost supplier of asbestos-free protection and insulation board. [6] Although it had a full listing during the 1980s it was at that time 67.3% owned by Charter Consolidated plc. [6]
In May 1997, the manufacture and use of crocidolite and amosite, commonly known as blue and brown asbestos, were fully banned in South Korea. In January 2009, a full-fledged ban on all types of asbestos occurred when the government banned the manufacture, import, sale, storage, transport or use of asbestos or any substance containing more than ...
