Until the mid-1980s, small amounts of white asbestos were used in the manufacture of Artex , a decorative stipple finish, however, some of the lesser-known suppliers of Artex-type materials were still adding white asbestos until 1999. Before the ban, asbestos was widely used in the construction industry in thousands of materials. Some are judged to be more dangerous than others due to
288-774: A certified asbestos-testing laboratory found the tremolite form of amphibole asbestos used to be found in three out of eight popular brands of children's crayons that were made partly from talc: Crayola , Prang, and RoseArt. In Crayola crayons, the tests found asbestos levels around 0.05% in Carnation Pink and 2.86% in Orchid ; in Prang crayons, the range was from 0.3% in Periwinkle to 0.54% in Yellow ; in Rose Art crayons, it

The first such study was conducted by Murray at the Charing Cross Hospital , London , in 1900, in which a postmortem investigation discovered asbestos traces in the lungs of a young man who had died from pulmonary fibrosis after having worked for 14 years in an asbestos textile factory. Adelaide Anderson , the Inspector of Factories in Britain, included asbestos in
432-621: A list of harmful industrial substances in 1902. Similar investigations were conducted in France in 1906 and Italy in 1908. The first diagnosis of asbestosis was made in the UK in 1924. Nellie Kershaw was employed at Turner Brothers Asbestos in Rochdale , Greater Manchester , England , from 1917, spinning raw asbestos fibre into yarn. Her death in 1924 led to a formal inquest. Pathologist William Edmund Cooke testified that his examination of

In spite of that, in June 2000 Binney & Smith, the maker of Crayola, and the other makers agreed to stop using talc in their products, and changed their product formulations in the United States. The mining company R T Vanderbilt Co of Gouverneur, New York , which supplied
576-464: A potential health hazard and is no longer used at all. Amphiboles including amosite (brown asbestos) and crocidolite (blue asbestos) were formerly used in many products until the early 1980s. Tremolite asbestos constituted a contaminant of many if not all naturally occurring chrysotile deposits. The use of all types of asbestos in the amphibole group was banned in much of the Western world by

As a result of Cooke's paper, Parliament commissioned an inquiry into the effects of asbestos dust by E. R. A. Merewether, Medical Inspector of Factories, and C. W. Price , a factory inspector and pioneer of dust monitoring and control. Their subsequent report, Occurrence of Pulmonary Fibrosis & Other Pulmonary Affections in Asbestos Workers ,
720-502: A result of these health effects, asbestos is considered a serious health and safety hazard . Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent thermal and electrical insulator , and
792-521: Is amiantos ("undefiled", "pure"), which was adapted into the French as amiante and into Spanish and Portuguese as amianto . In modern Greek , the word ἀσβεστος or ασβέστης stands consistently and solely for lime . The term asbestos is traceable to Roman naturalist Pliny the Elder 's first-century manuscript Natural History and his use of the term asbestinon , meaning "unquenchable"; he described

The latency period (from exposure until the diagnosis of negative health effects) is typically 20 years. The most common diseases associated with chronic asbestos exposure are asbestosis (scarring of the lungs due to asbestos inhalation) and mesothelioma (a type of cancer). Many developing countries still support

Cutting these sheets to size and drilling holes to receive 'J' bolts to help secure the sheets to roof framing is done on-site. There has been no significant change in production and use of A/C sheets in developing countries following
1080-566: Is highly fire resistant, so for much of the 20th century, it was very commonly used around the world as a building material (particularly for its fire-retardant properties), until its adverse effects on human health were more widely recognized and acknowledged in the 1970s. Many buildings constructed before the 1980s contain asbestos. The use of asbestos for construction and fireproofing has been made illegal in many countries. Despite this, around 255,000 people are thought to die each year from diseases related to asbestos exposure. In part, this
1152-491: Is not a material covered under CERCLA 's innocent purchaser defense. In the UK, the removal and disposal of asbestos and substances containing it are covered by the Control of Asbestos Regulations 2006 . U.S. asbestos consumption hit a peak of 804,000 tons in 1973; world asbestos demand peaked around 1977, with 25 countries producing nearly 4.8 million metric tons annually. In older buildings (e.g. those built before 1999 in

A once-purported first description of asbestos occurs in Theophrastus , On Stones , from around 300 BC, but this identification has been refuted. In both modern and ancient Greek , the usual name for the material known in English as "asbestos"
1368-571: Is thrown into the fire, is made ..." The large-scale asbestos industry began in the mid-19th century. Early attempts at producing asbestos paper and cloth in Italy began in the 1850s but were unsuccessful in creating a market for such products. Canadian samples of asbestos were displayed in London in 1862, and the first companies were formed in England and Scotland to exploit this resource. Asbestos

A notable exception is the United States, where asbestos continues to be used in construction such as cement asbestos pipes. The 5th Circuit Court prevented the EPA from banning asbestos in 1991 because EPA research showed the ban would cost between US$ 450 and 800 million while only saving around 200 lives in
1800-601: The Franklin, Adventure , Allouez, and Centennial mines. As a result of low copper prices and the onset of the Great Depression , the Quincy Mining Company ceased operations on September 22, 1931. The company boarded up facilities including the smelter. The mine itself remained closed from 1931 through 1936, until an increase in copper prices in 1937 prompted reopening the mine. Instead of reopening

US production began in earnest in 1899 with the discovery of large deposits in Belvidere Mountain in Vermont. The use of asbestos became increasingly widespread toward the end of the 19th century when its diverse applications included fire-retardant coatings, concrete, bricks, pipes and fireplace cement, heat-, fire-, and acid-resistant gaskets, pipe insulation, ceiling insulation, fireproof drywall, flooring, roofing, lawn furniture, and drywall joint compound. In 2011, it

However, the reclamation project continued as it was very productive and less expensive than mining. In June 1948, the Quincy Smelter reopened as Calumet and Hecla was no longer able to meet Quincy's needs. Around the same time, the Copper Range Company closed the Michigan Smelter and contracted its smelting needs with Quincy. Reclamation

Such cloth is believed to have been made of asbestos imported over the Hindu Kush . According to Biruni in his book Gems , any cloths made of asbestos ( Persian : آذرشست , āzarshost ) were called shostakeh ( Persian : شستكه ). Some Persians believed the fiber was the fur of an animal called
2664-477: The late 1890s, the quantity of rock mined by Quincy justified the company building its own smelter. In May 1898, the Quincy Mining Company started construction of the Quincy Smelter on the stamp sands of the old Pewabic mill; Quincy had acquired the Pewabic Mining Company in 1891. The shoreline was dredged and pilings were inserted for the loading dock. This was followed by laying foundations for

Talc can sometimes be contaminated with asbestos due to the proximity of asbestos ore (usually tremolite ) in underground talc deposits. By 1973, US federal law required all talc products to be asbestos-free. Separating cosmetic-grade talc (e.g. talcum powder) from industrial-grade talc (often used in friction products) has largely eliminated this issue for consumers. Cosmetics companies, including Johnson & Johnson, have known since

The most common type of asbestos, chrysotile, chemically reacts with CO 2 to produce ecologically stable magnesium carbonate . Chrysotile , like all types of asbestos, has a large surface area that provides more places for chemical reactions to occur, compared to most other naturally occurring materials. The use of asbestos in new construction projects has been banned for health and safety reasons in many developed countries or regions, including

In the late 1970s, court documents proved that asbestos industry officials knew of asbestos dangers since the 1930s and had concealed them from the public. In Australia, asbestos was widely used in construction and other industries between 1946 and 1980. From the 1970s, there was increasing concern about the dangers of asbestos, and following community and union campaigning, its use

It concluded that the development of asbestosis was irrefutably linked to the prolonged inhalation of asbestos dust, and included the first health study of asbestos workers, which found that 66% of those employed for 20 years or more suffered from asbestosis. The report led to the publication of the first asbestos industry regulations in 1931, which came into effect on 1 March 1932. These rules regulated ventilation and made asbestosis an excusable work-related disease. The term mesothelioma
