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 ...
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.
The fibrous forms of riebeckite are known as crocidolite and are one of the six recognised types of asbestos. 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]
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 ...
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.
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.
The company was founded in 1920 in Chicago, Illinois as a subsidiary of Philip Carey Corporation, to manufacture its namesake product Celotex insulation board, often called simply Celotex. Celotex is a fiberboard made from bagasse (sugar cane waste after extraction of the juice), first produced in a factory in Marrero, Louisiana , outside of ...
The use of asbestos, a proven carcinogen, to manufacture transite was phased out in the 1980s. It was replaced by crystalline silica, which the International Agency for Research on Cancer has classified as being carcinogenic to humans (Class 1). [2] Crystalline silica is also known to cause silicosis, a non-cancerous lung disease. [3]
