Mineral wool and glass wool are fiber materials made from slag, rock, glass, and minerals that have been melted and spun into filaments. Volume 43, World Health Organization, Lyon, France, 1988. In 1987, IARC determined that glass wool was a “possible human carcinogen”. Glass wool is a thermal insulation material consisting of intertwined and flexible glass fibers, which causes it to "package" air, resulting in a low density that can be varied through compression and binder content (as noted above, these air cells are the actual insulator). Corrosion Resistance. Glass wool Air-conditioning Board can insulate, save energy and reduce the cost for the air-conditioner system. [1,pg.292] At the Columbian Exposition in Chicago in 1893, Edward Libbey, an American, exhibited lamp shades, a dress, and other articles woven from glass fibers. The term “mineral wool” is used in Europe to cover glass, stone (rock) and slag wool and new fibre types. Update of potency factors for asbestos-related lung cancer and mesothelioma. This material texture is very much similar to wool which is why it is named as glass wool. The low risk of 6 in a million per year of a worker blowing glass wool is consistent with the fact that no one has found any of cancer attributable to the manufacture or installation of glass wool fibers in spite of diligent searches. There are good estimates of the risk associated with exposure to chrysotile asbestos at high exposures and doses. However, there is considerable evidence that differences exist among fibers in their potency to produce a carcinogenic response. IARC Monographs on the Identification of Carcinogenic Hazards to Humans. Not all glass wool or man-made fibers were found to be carcinogenic, NTP said in announcing the report's release. 1999 Oct;30(2 Pt 1):96-109. doi: 10.1006/rtph.1999.1344. Glass wool and stone wool products with EUCEB Certificate are fibres proved not to be carcinogenic. A meta-analysis of asbestos-related cancer risk that addresses fiber size and mineral type. The epidemiological evidence is sufficient to conclude that there has been no mesothelioma risk to workers producing or using glass wool, rock wool, or slag wool. Man-made mineral (vitreous) fibres: evaluations of cancer hazards by the IARC Monographs Programme. Testing of bonded glasswool and rockwool insulation The newer forms of rockwool pose little risk of breathing it in. Criteria for a Recommended Standard: Occupational Exposure to Fibrous Glass. Related NIOSH Resources. - PR11550028 But in this case, as in many other situations where there is a potential hazard, society desires further reassurance and therefore we have made a mechanistic calculation.

Possible application of urinary analysis to estimate dissolution of some man-made vitreous fibers. In October 2001, IARC removed insulation glass wool from the list of possible carcinogens. However, this hazard is not associated with any index of exposure to slag wool itself. COVID-19 is an emerging, rapidly evolving situation. This is … Particulate matter includes a variety of different compounds that are naturally present as tiny particles. It is suggested that the present IARC evaluation of the carcinogenic risk of insulation wools should be revised to Category 3: not classifiable as to carcinogenicity to humans. Glass wool (originally known also as fiberglass) is an insulating material made from fibres of glass arranged using a binder into a texture similar to wool.Glass wool and stone wool are produced from mineral fibres and are therefore often referred to as ‘mineral wools’. We expect labeling requirements to change in the near future. RDF's completely unrelated to asbestos such as fiberglass and rock wool are equally carcinogenic." It is widely considered as a thermal insulation material in ships, automobiles, air conditioning ducts and water supply pipes.

This site needs JavaScript to work properly. Glass Wool. NIH Certain special purpose glass fibres are possibly carcinogenic. These particles are, in some cases, mined for human use. This means that out of a million installers there might be six lung cancers from this cause every year or out of 10,000 installers there might be one in 16 years. COVID-19 is an emerging, rapidly evolving situation. HHS Since the three principal types of asbestos fibers types have caused lung cancer at high exposures, there is a widely held belief that all fibers are carcinogenic if inhaled in large enough doses.

The substance is toxic to lungs, mucous membranes. Alibaba.com offers 4,081 glass wool in roll products. Glass wool is made up of short glass fibres and is non-flammable in nature. FREE Shipping. Glass fibers can generally be classified into two categories based on usage: (1) Low-cost, general-purpose fibers typically used for insulation applications (2) Premium special-purpose fibers used in limited specialized applications. Experience from a long-term carcinogenicity study with intraperitoneal injection of biosoluble synthetic mineral fibers. The epidemiological studies have been large and powerful, and they show no evidence of a cause-effect relationship between lung cancer and exposure to glass wool, rock wool, or slag wool fibers. Publications. In this attempt to carry out a numerical risk assessment for the installers of blown glass wool (fiber) insulation, we start with a characterization of the material; then we review the exposures both in manufacturing and installation. 99. Mutat Res. Do NOT take working clothes home. More than 1,200 references to the recent literature are included. Glass wool is an insulating material made from fibres of glass arranged using a binder into a texture similar to wool.

The available studies in experimental animals clearly demonstrate that glass wool fibers are carcinogenic; however, their utility for predicting the carcinogenic- ity of specific fibers or groups of fibers is limited, for several reasons: (1) Only a subset of commercially available fibers have been tested. USA.gov. Fibers in this material are long, thin, and tiny. In October 2001, IARC reviewed the scientific data now available and removed insulation glass wool from the list of possible carcinogens.

Insulation glass wool, continuous glass filament, rock wool (ICSC 0194) and slag wool (ICSC 0195) are not classifiable as carcinogenic. HHS The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties. Some argue that fibrous glass (glass wool) should not be considered as a likely human carcinogen and hence should not be listed in the Seventh Annual Report on Carcinogens (ARC) prepared by the National Toxicology Program (NTP) and mandated by the U.S. Congress. Multiple chronic inhalation studies of these same special-purpose fine glass fibers have not produced evidence of carcinogenicity. Independent sampling institution takes samples from manufacturers with the certificate biannually, and sends this sample to an independent test centre for the chemical analysis.

Now it is produced from recycled newspapers which are treated with chemicals which reduces its ignition power. Regul Toxicol Pharmacol. This material separates air into layers, making it very good at trapping heat especially in controlling the heat in a structure and it is also used as a good sound proofing material. NLM But while some research suggests that inhaling fiberglass particles could cause cancer, but in 2001, the International Agency for Research on Cancer removed glass, rock and slag wool fibers -- common elements of fiberglass insulation -- from its list of substances possibly carcinogenic to humans [sources: NTP, IARC]. The risk for a nonsmoking installer of glass wool fiber insulation who wears a respirator is about 6 in a million (and might be zero) per year. There has been concern that certain glass wool fibres are human carcinogens. This reclassification may lead other agencies that also classified glass wool in the early and mid 1990’s, to review their assessments and possibly reclassify these fibers. Because several metallic salts and pigments are used in the manufacture and colouring of certain glass products, the book also evaluates the carcinogenic risk posed by exposures in the glass manufacturing industry. by ACGIH.
