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 ...
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]
Production of Asbestolux, a new form of non-combustible asbestos board, started. "In a short time, [Cape Products] was an invaluable feature in Cape's economy" (op. cit. page 72). However, it is noteworthy that at no relevant point in time did Cape cease to be an operating company itself or merely hold the shares in its subsidiaries as if it ...
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.
In construction, asbestos abatement is a set of procedures designed to control the release of asbestos fibers from asbestos-containing materials. [1] Asbestos abatement is utilized during general construction in areas containing asbestos materials, particularly when those materials are being removed, encapsulated, or repaired.
Regulations to ban asbestos in South Africa occurred in March 2008 under the leadership of Environmental Affairs and Tourism Minister Marthinus van Schalkwyk. The first draft regulations were announced in November 2005 for public comment and again in September 2007.
