Asbestos

The word "asbestos", first used in the 1600s, ultimately derives from the {{langx|grc|ἄσβεστος}}, meaning "unquenchable" or "inextinguishable".{{Cite journal|date=July 1997 |author=Alleman, James E. |author2=Mossman, Brooke T|author2-link= Brooke T.

It was adopted into English via the Old French abestos, which got the word from Greek via Latin, but in the original Greek, "asbestos" actually referred to quicklime. It is said by the Oxford English Dictionary that the word was wrongly used by Pliny for what we now call asbestos, and that he popularized the misnomer. Asbestos was originally referred to in Greek as amiantos, meaning "undefiled",{{LSJ|a)mi/antos|ἀμίαντος|shortref}}. because when thrown into a fire it came out unmarked. "Amiantos" is the source for the word for asbestos in many languages, such as the Portuguese, the Spanish, and the Italian amianto and the French amiante. It had also been called "amiant" in English in the early 15th century, but this usage was superseded by "asbestos".{{Cite web|url=https://www.etymonline.com/word/asbestos|title=asbestos {{!}} Origin and meaning of asbestos by Online Etymology Dictionary|website=www.etymonline.com|language=en|access-date=2018-12-14}} The word is pronounced {{IPAc-en|æ|s|ˈ|b|ɛ|s|t|ə|s}} or {{IPAc-en|æ|s|ˈ|b|ɛ|s|t|ɒ|s}}.{{cite web |title=asbestos |url=https://en.oxforddictionaries.com/definition/asbestos |archive-url=https://web.archive.org/web/20190321081058/https://en.oxforddictionaries.com/definition/asbestos |archive-date=21 March 2019 |website=Oxford Living Dictionaries |publisher=Oxford University Press |access-date=21 March 2019}}

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 was first used in the manufacture of yarn, and German industrialist Louis Wertheim adopted this process in his factories in Germany.{{cite book|url=https://books.google.com/books?id=ARKaW4uP9BgC|title=Asbestos and Disease|author=Selikoff, Irving J.|publisher=Elsevier|year=1978|isbn=978-0-323-14007-2|pages=8–20}} In 1871, the Patent Asbestos Manufacturing Company was established in Glasgow, and during the following decades, the Clydebank area became a centre for the nascent industry.{{cite web|url=http://www.clydebankasbestos.org/index.php?page=asbestos-clydebank|title=Asbestos & Clydebank|publisher=Clydebank Asbestos Group|archive-url=https://web.archive.org/web/20140606230508/http://www.clydebankasbestos.org/index.php?page=asbestos-clydebank|archive-date=6 June 2014}}

Industrial-scale mining began in the Thetford hills, Quebec, from the 1870s. Sir William Edmond Logan was the first to notice the large deposits of chrysotile in the hills in his capacity as head of Geological Survey of Canada. Samples of the minerals from there were displayed in London and elicited much interest. With the opening of the Quebec Central Railway in 1876, mining entrepreneurs such as Andrew Stuart Johnson established the asbestos industry in the province.[http://www.ourroots.ca/e/toc.aspx?id=11253 The storied province of Quebec : past and present.

Asbestos production began in the Urals of the Russian Empire in the 1880s, and the Alpine regions of Northern Italy with the formation in Turin of the Italo-English Pure Asbestos Company in 1876, although this was soon swamped by the greater production levels from the Canadian mines.

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 was reported that over 50% of UK houses still contained asbestos, despite a ban on asbestos products some years earlier.Don, Andrew (1 May 2011) [https://www.theguardian.com/money/2011/may/01/asbestos-hidden-health-hazard Asbestos: the hidden health hazard in millions of homes].

In Japan, particularly after World War II, asbestos was used in the manufacture of ammonium sulfate for purposes of rice production, sprayed upon the ceilings, iron skeletons, and walls of railroad cars and buildings (during the 1960s), and used for energy efficiency reasons as well. Production of asbestos in Japan peaked in 1974 and went through ups and downs until about 1990 when production began to drop dramatically.{{cite web|url=http://www.hvbg.de/e/asbest/konfrep/konfrep/repbeitr/morinaga_en.pdf|title=Asbestos in Japan|author=Morinaga, Kenji|work=European Conference 2003|archive-url=https://web.archive.org/web/20110719043338/http://www.hvbg.de/e/asbest/konfrep/konfrep/repbeitr/morinaga_en.pdf|archive-date=19 July 2011|access-date=12 January 2010}}

In the early 1900s, researchers began to notice a large number of early deaths and lung problems in asbestos-mining towns. 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 a list of harmful industrial substances in 1902.

The United States government and the asbestos industry have been criticized for not acting quickly enough to inform the public of dangers and to reduce public exposure. 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 was phased out, with mining having ceased in 1983.{{Cite web |last=Commons Librarian |date=2023-12-22 |title=Campaigns that Changed Western Australia |url=https://commonslibrary.org/campaigns-that-changed-western-australia/ |access-date=2024-04-19 |website=The Commons Social Change Library |language=en-AU}} The use of asbestos was phased out in 1989 and banned entirely in December 2003.

Serpentine minerals have a sheet or layered structure. Chrysotile (commonly known as white asbestos) is the only asbestos mineral in the serpentine group. In the United States, chrysotile has been the most commonly used type of asbestos.

Amphiboles including amosite (brown asbestos) and crocidolite (blue asbestos) were formerly used in many products until the early 1980s. {{citation needed|date=August 2012}} 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 the mid-1980s, and in Japan by 1995.{{Cite web | url=http://www.umt.edu/bioethics/libbyhealth/Resources/Legal%20Resources/international_ban_asbestos.aspx |title = International Bans on Asbestos Use – Asbestos and Libby Health – the University of Montana}} Some products that included amphibole types of asbestos included the following:

• Low-density insulating board (often referred to as AIB or asbestos insulating board) and ceiling tiles;
• Asbestos cement sheets and pipes for construction, casing for water and electrical/telecommunication services;
• Thermal and chemical insulation (e.g., fire-rated doors, limpet spray, lagging, and gaskets).
• Electrical wiring, braided cables, cable wrap, wire insulation (usually crocidolite)

The potential for use of asbestos to mitigate climate change has been raised. Although the adverse aspects of mining of minerals, including health effects, must be taken into account, exploration of the use of mineral wastes to sequester carbon is being studied. The use of mining waste materials from nickel, copper, diamond, and platinum mines have the potential as well, but asbestos may have the greatest potential and is the subject of research now in progress in an emerging field of scientific study to examine it. The most common type of asbestos, chrysotile, chemically reacts with carbon dioxide 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.Temple, James, [https://www.technologyreview.com/2020/10/06/1009374/asbestos-could-be-a-powerful-weapon-against-climate-change-you-read-that-right/ Asbestos could be a powerful weapon against climate change (you read that right)], MIT Technology Review, October 6, 2020

The use of asbestos in new construction projects has been banned for health and safety reasons in many developed countries or regions, including the European Union, the United Kingdom, Australia, Hong Kong, Japan, and New Zealand. A notable exception is the United States, where asbestos continues to be used in construction such as cement asbestos pipes.{{citation needed|date=October 2024}} 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 a 13-year timeframe, and that the EPA did not provide adequate evidence for the safety of alternative products.[http://openjurist.org/947/f2d/1201/corrosion-proof-fittings-v-environmental-protection-agency 947 F. 2d 1201 – Corrosion Proof Fittings v.

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 the amount of asbestos and the material's friable nature. Loose fill asbestos, sprayed coatings, pipe insulation, and Asbestos Insulating Board (AIB) are thought to be the most dangerous due to their high content of asbestos and friable nature.https://www.hse.gov.uk/asbestos/location-materials.htm Many older buildings built before the late 1990s contain asbestos. In the United States, there is a minimum standard for asbestos surveys as described by ASTM standard E 2356–18.

Some countries, such as India, Indonesia, China and Russia, have continued widespread use of asbestos. The most common is corrugated asbestos-cement sheets or "A/C sheets" for roofing and sidewalls. Millions of homes, factories, schools or sheds, and shelters continue to use asbestos. Cutting these sheets to size and drilling holes to receive 'J' bolts to help secure the sheets to roof framing is done on-site.

Chrysotile has been used more than any other type and accounts for about 95% of the asbestos found in buildings in America.{{cite web|title=Asbestos – History and Uses|date=31 August 2007|publisher=Wisconsin Department of Natural Resources |archive-url=https://web.archive.org/web/20071228042633/http://www.dnr.state.wi.us/org/aw/air/reg/asbestos/asbes3.htm |archive-date=28 December 2007|url=http://www.dnr.state.wi.us/org/aw/air/reg/asbestos/asbes3.htm}} Chrysotile is more flexible than amphibole types of asbestos and can be spun and woven into fabric. The most common use was corrugated asbestos cement roofing primarily for outbuildings, warehouses, and garages. It may also be found in sheets or panels used for ceilings and sometimes for walls and floors. Chrysotile has been a component in joint compound and some plasters. Numerous other items have been made containing chrysotile including brake linings, fire barriers in fuseboxes, pipe insulation, floor tiles, residential shingles, and gaskets for high-temperature equipment.{{Cite web |last=Loreto |first=Olga |date=2018-09-18 |title=What is Asbestos?

Amphibole class fibers are needle-like. Amosite, crocidolite, tremolite, anthophyllite and actinolite are members of the amphibole class.

Amosite, CAS No. {{Cas|12172-73-5}}, often referred to as brown asbestos, is a trade name for the amphiboles belonging to the cummingtonite-grunerite solid solution series, commonly from South Africa, named as a partial acronym for "Asbestos Mines of South Africa". One formula given for amosite is {{chem2|Fe7Si8O22(OH)2}}. Amosite is seen under a microscope as a grey-white vitreous fiber. It is found most frequently as a fire retardant in thermal insulation products, asbestos insulating board and ceiling tiles.

Crocidolite,{{pronunciation needed}} CAS No. {{Cas|12001-28-4}}, commonly known as blue asbestos, is the fibrous form of the amphibole riebeckite, found primarily in southern Africa, but also in Australia and Bolivia. One formula given for crocidolite is {{chem2|Na2Fe^{II}3Fe^{III}2Si8O22(OH)2}}. Crocidolite is seen under a microscope as a blue fiber.

Crocidolite commonly occurs as soft friable fibers. Asbestiform amphibole may also occur as soft friable fibers but some varieties such as amosite are commonly straighter. All forms of asbestos are fibrillar in that they are composed of fibers with breadths less than 1 micrometer in bundles of very great widths. Asbestos with particularly fine fibers is also referred to as "amianthus".

Other regulated asbestos minerals, such as tremolite asbestos, CAS No. {{Cas|77536-68-6}}, {{chem2|Ca2Mg5Si8O22(OH)2}}; actinolite asbestos, CAS No. 77536-66-4, {{chem2|Ca2(Mg,Fe^{II})5(Si8O22)(OH)2}}; and anthophyllite asbestos, CAS No. {{Cas|77536-67-5}}, {{chem2|(Mg,Fe^{II})7Si8O22(OH)2}}; are less commonly used industrially but can still be found in a variety of construction materials and insulation materials and have been used in a few consumer products.

Other natural asbestiform minerals, such as richterite, {{chem2|Na(CaNa)(Mg,Fe^{II})5(Si8O22)(OH)2}}, and winchite, {{chem2|(CaNa)Mg4(Al,Fe^{III})(Si8O22)(OH)2}}, though not regulated, are said by some to be no less harmful than tremolite, amosite, or crocidolite.[https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=PREAMBLES&p_id=782 Occupational Exposure to Asbestos, Tremolite, Anthophyllite and Actinolite] {{Webarchive|url=https://web.archive.org/web/20170503230609/https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=PREAMBLES&p_id=782 |date=3 May 2017 }}.

Although the U.S. Occupational Safety and Health Administration (OSHA) has not included them in the asbestos standard, NIOSH and the American Thoracic Society have recommended them for inclusion as regulated materials because they may also be hazardous to health.

"Mountain leather" is an old-fashioned term for flexible, sheet-like natural formations of asbestiform minerals which resemble leather. Asbestos-containing minerals known to form mountain leather include: actinolite, sepiolite, and tremolite.{{Cite web|title=Mountain Leather|url=https://www.mindat.org/min-9168.html|access-date=2021-09-20|website=www.mindat.org}}

During the 1980s and again in the 1990s, the asbestos industry suggested at times that the process of making asbestos cement could "neutralize" the asbestos, either via chemical processes or by causing the cement to attach to the fibers and changing their physical size; subsequent studies showed that this was untrue and that decades-old asbestos cement, when broken, releases asbestos fibers identical to those found in nature, with no detectable alteration.{{cite web|url=http://www.hse.gov.uk/research/hsl_pdf/2007/hsl0711.pdf|title=Investigation of the chrysotile fibres in an asbestos cement sample (2006) – HSL/2007/11, p.26 onward|website=www.hse.gov.uk]|access-date=5 April 2015|archive-date=14 February 2019|archive-url=https://web.archive.org/web/20190214180028/http://www.hse.gov.uk/research/hsl_pdf/2007/hsl0711.pdf|url-status=dead}}

Exposure to asbestos in the form of fibers is always considered dangerous. Working with, or exposure to, material that is friable, or materials or works that could cause the release of loose asbestos fibers, is considered high risk. In general, people who become ill from inhaling asbestos have been regularly exposed in a job where they worked directly with the material.{{Cite web|url=https://cpdonline.co.uk/knowledge-base/health-and-safety/what-does-asbestos-do/|title=What does asbestos do to you? {{!}} Affects of exposure and who is at risk|date=17 July 2019|website=CPD Online College|language=en-GB|access-date=2019-08-13}}

A low-grade Chrysotile was mined here from 1908 to 1917 but only 100 tons were washed and taken out by packhorse.

This continued to 1964, when, due to the short length of its fibre, the limited commercial viability forced mining to cease.{{Cite news|url=http://paperspast.natlib.govt.nz/cgi-bin/paperspast?a=d&d=GRA18980108.2.14|title=National Library of New Zealand|work=Grey River Argus, Volume LVII, Issue 9871, 8 January 1898, Page 4}}{{Cite book|title=The Cobb: the history of the Cobb River hydro-electric power scheme|last=Blair|first=AK|publisher=Cadsonbury Publications, Christchurch, 1998|year=1994|isbn=0-477-01699-5|location=Christchurch, New Zealand|pages= 67–69, 71–72, 100–101}}

In May 1997, the manufacture and use of crocidolite and amosite, commonly known as blue and brown asbestos, were fully banned in South Korea.[http://www.fnn.co.kr/content.asp?aid=504579c1e94a43f8ad80a83ee2aa0433 "학원 밀집 건물 석면노출 심각"] {{Webarchive|url=https://web.archive.org/web/20150402105233/http://www.fnn.co.kr/content.asp?aid=504579c1e94a43f8ad80a83ee2aa0433 |date=2 April 2015 }}. fnn.co.kr. 6 May 2013 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 0.1% of asbestos.{{cite journal|last=Kim|first=Hyoung Ryoul|title=Overview of Asbestos Issues in Korea|journal=J Korean Med Sci|date=12 June 2009|volume=24|series=3|pages=363–367|doi=10.3346/jkms.2009.24.3.363|pmid=19543418|pmc=2698178|issue=3}} In 2011, South Korea became the world's sixth country to enact an asbestos harm aid act, which entitles any Korean citizen to free lifetime medical care as well as monthly income from the government if they are diagnosed with an asbestos-related disease.[http://health.joseilbo.com/html/news/?f=read&code=1327972365&seq=2992 1970~80년대 석면 다룬 산업 근로자, 폐암 정기검사 필수] {{Webarchive|url=https://web.archive.org/web/20150402192750/http://health.joseilbo.com/html/news/?f=read&code=1327972365&seq=2992 |date=2 April 2015 }}. health.joseilbo.com. 25 February 2013

In the United Kingdom, blue and brown asbestos materials were banned outright in 1985 while the import, sale, and secondhand reuse of white asbestos was outlawed in 1999. The 2012 Control of Asbestos Regulations, updating and replacing the previous 2006 law, state that owners of non-domestic buildings (e.g., factories and offices) have a "duty to manage" asbestos on the premises by making themselves aware of its presence and ensuring the material does not deteriorate, removing it if necessary. Employers, e.g. construction companies, whose operatives may come into contact with asbestos must also provide annual asbestos training to their workers.{{cite book |title=Managing and working with asbestos – Control of Asbestos Regulations 2012 |date=2013 |publisher=Health and Safety Executive |location=London |isbn=978-0-7176-6618-8 |url=https://www.hse.gov.uk/pubns/priced/l143.pdf |url-status=live |archive-url=https://web.archive.org/web/20231216144646/https://www.hse.gov.uk/pubns/priced/l143.pdf |archive-date= Dec 16, 2023 }}

In 1989, the United States Environmental Protection Agency (EPA) issued the Asbestos Ban and Phase-Out Rule, but in 1991, asbestos industry supporters challenged and overturned the ban in a landmark lawsuit: Corrosion Proof Fittings v. Environmental Protection Agency.{{cite court |url=https://law.justia.com/cases/federal/appellate-courts/F2/947/1201/153685/ |litigants=Corrosion Proof Fittings v. EPA |vol=1201 |reporter=947 F.2d |court=5th Cir. |date=1991}} Although the case resulted in several small victories for asbestos regulation, the EPA ultimately did not put an end to asbestos use. The ruling left many consumer products that can still legally contain trace amounts of asbestos. Six categories of asbestos-containing products are however banned: corrugated paper, rollboard, commercial paper, specialty paper, flooring felt and any new uses of asbestos. The Clean Air Act also bans asbestos pipe insulation and asbestos block insulation on components such as boilers and hot water tanks, and spray-applied surfacing asbestos-containing materials. The Consumer Product Safety Act bans asbestos in artificial fireplace embers and wall patching compounds. The Food and Drug Administration bans asbestos-containing filters in pharmaceutical manufacturing, processing, and packing.{{cite web |url=http://www.epa.gov/asbestos/pubs/asbbans2.pdf |archive-url=https://web.archive.org/web/20121022215630/http://www.epa.gov/asbestos/pubs/asbbans2.pdf |archive-date=22 October 2012 |title=EPA Asbestos Materials Bans: Clarification |publisher=Environmental Protection Agency |date=18 May 1999}}{{cite web |title=EPA Actions to Protect the Public from Exposure to Asbestos |date=12 March 2013 |url=https://www.epa.gov/asbestos/epa-actions-protect-public-exposure-asbestos#banneduses |publisher=United States Environmental Protection Agency |access-date=28 April 2020}}

Since 1970, as a result of increased regulation of asbestos in Europe and in the United States, there was a massive transfer of asbestos-processing enterprises to Mexico. Asbestos is used in many products – roofing, boilers, pipes, brakes, and wires, produced by over 2,000 Mexican companies, many of them subsidiaries or subcontractors of US companies, and sold throughout the Americas. In 2000, 58% of Mexican asbestos-containing exports went to the United States, and 40% to Central American countries and Cuba.{{cite journal |last1=Algranti |first1=Eduardo |last2=Ramos-Bonilla |first2=Juan Pablo |last3=Terracini |first3=Benedetto |last4=Santana |first4=Vilma S.

In Vietnam, chrysotile asbestos is not banned and is still widely used. Amphibole asbestos is banned from trade and use. Vietnam is one of the top 10 asbestos users in the world, with an annual import volume of about 65,000–70,000 tons of chrysotile.[https://plo.vn/suc-khoe/tam-lop-amiang-ke-giet-nguoi-732227.html Tấm lợp amiăng, kẻ giết người?], báo Pháp Luật, 10 July 2017, language=vietnamese About 90% of the imported asbestos is used to produce about 100 million m² of cement roofing sheets (asbestos-cement). According to one study, among 300 families in Yen Bai, Thanh Hoa, 85% of households use asbestos roofing sheets, but only 5% know about the negative health effects.

The master plan (for construction materials development to 2020 with orientation to 2030 submitted by the Ministry of Construction to the Government in January 2014) still suggests continued use of chrysotile for a long time.[https://plo.vn/thoi-su/xay-dung-mang-luoi-cam-su-dung-amiang-trang-o-viet-nam-512026.html Xây dựng mạng lưới cấm sử dụng amiăng trắng ở Việt Nam], báo Pháp Luật, 27 November 2014, language=vietnamese

In 1978, a highly texturized fiberglass fabric was invented by Bal Dixit, called Zetex. This fabric is lighter than asbestos but offers the same bulk, thickness, hand, feel, and abrasion resistance as asbestos. The fiberglass was texturized to eliminate some of the problems that arise with fiberglass, such as poor abrasion resistance and poor seam strength.Dixit, B., [https://books.google.com/books?id=JkaAypWOi0AC&pg=PA446 "Performance of Protective Clothing: Development and Testing of Asbestos Substitutes"], Performance of Protective Clothing, ASTM STP 900, R.

In Europe, mineral wool and glass wool are the main insulators in houses.

Many companies that produced asbestos-cement products that were reinforced with asbestos fibers have developed products incorporating organic fibers. One such product was known as "Eternit" and another "Everite" now use "Nutec" fibers which consist of organic fibers, portland cement and silica. Cement-bonded wood fiber is another substitute. Stone fibers are used in gaskets and friction materials.

Another potential fiber is polybenzimidazole or PBI fiber. Polybenzimidazole fiber is a synthetic fiber with a high melting point of {{convert|760|C}} that also does not ignite. Because of its exceptional thermal and chemical stability, it is often used by fire departments and space agencies.

In most developed countries, asbestos is typically disposed of as hazardous waste in designated landfill sites.

The demolition of buildings containing large amounts of asbestos-based materials pose particular problems for builders and property developers – such buildings often have to be deconstructed piece by piece, or the asbestos has to be painstakingly removed before the structure can be razed by mechanical or explosive means. One such example is the Red Road Flats in Glasgow, Scotland which used huge amounts of asbestos cement board for wall panelling – British health and safety regulations stipulate that asbestos material has to be removed in specially adapted vehicles and taken to a landfill site with an appropriate permit to accept asbestos, via an approved route, at certain times of the day.{{citation needed|date=October 2023}}

In the United States, the EPA governs the removal and disposal of asbestos strictly. Companies that remove asbestos must comply with EPA licensing. These companies are called EPA licensed asbestos contractors. Anytime one of these asbestos contractors performs work a test consultant has to conduct strict testing to ensure the asbestos is completely removed.{{citation needed|date=October 2023}}
