However, they can still be found today, as they were regularly added to materials prior to regulation.įriable asbestos is often found in products like thermal insulation for pipes, insulation for water heaters, joint compounds, ceiling tiles, plasters, and wallboards. Friable asbestos-containing materials (ACMs), which crumble more easily than non-friable types, are now regulated due to their release of asbestos and associated risks. When identifying asbestos, it’s possible to evaluate how easily it crumbles to determine whether it is friable or non-friable. Friable asbestos crumbles easily and falls apart under slight pressure. While rare, it is still possible to find asbestos-containing materials in newer buildings.” Although there are some ways to identify asbestos in the home, it’s generally a good idea to have a professional complete any testing and take care of the removal if asbestos is positively identified. According to Jordan Thomas, a senior environmental consultant at Indoor Science, “Generally any home built before the 1980s may have at least one asbestos-containing material. For this reason, it’s most common to find asbestos in houses built prior or 1989. In 1989, the Environmental Protection Agency (EPA) placed a partial ban on the use of asbestos in building materials. So where is asbestos found? As a result of its durability and resistance to heat, it has been used in flooring, insulation, ceiling tiles, siding, cement sheets, roofing, and textured ceiling coatings. Asbestos is commonly found in insulation, floor tiles, textured walls and ceilings, and siding that was installed prior to 1989.īefore it was discovered that asbestos can be hazardous and potentially fatal when inhaled, it was commonly used in construction materials. On the whole, these types of asbestos are relatively rare and are considered noncommercial. Trace amounts of tremolite in particular have also been found in cosmetic products. These have been found as contaminants in insulation and other building materials. Other types of asbestos include anthophyllite, tremolite, and actinolite, though their use in manufacturing was rare.Īnthophyllite, tremolite, and actinolite are all amphibole varieties of asbestos with a sharp, straight shape. Its fibers can be identified by their blue color. When it was used, it was commonly found in battery casings, spray-on coatings, roof tiles, pipe insulation, plastics, and cement products. Fortunately, it is relatively uncommon compared with other asbestos types because it is less heat-resistant. Because it is extremely fine, its tiny blue fibers are particularly easy to inhale. Like amosite, it is an amphibole asbestos. Crocidolite asbestos is blue in color and has thin fibers that can lodge in lung tissue.Īccording to Penn Medicine, crocidolite is the most hazardous of all types of asbestos. While it only accounts for about 5 percent of asbestos in buildings, amosite is considered to be one of the most hazardous varieties. It is an amphibole asbestos, meaning it is composed of delicate, needle-like strands that can easily become airborne when touched. Brown in color, this form of asbestos was frequently used in cement sheets and pipe insulation, as well as insulation boards, ceiling tiles, and thermal insulation products. and poses a greater risk of cancer than chrysotile. Amosite asbestos is brown in color and has a higher risk of causing cancer than chrysotile.Īmosite is the second most commonly used asbestos in the U.S. Its flexible but durable properties are some of the reasons for chrysotile’s popularity, as well as the fact that it is naturally resistant to heat and fire. Chrysotile falls under the category of serpentine asbestos, which is characterized by a curly, layered structure. There are two main families of asbestos: serpentine and amphibole. It has also been used in car parts such as brake linings, gaskets and boiler seals, and as insulation for pipes, ducts, and appliances. Much of the asbestos found in floor tiles is also chrysotile. This kind of asbestos is commonly found in roofs, ceilings, and walls of buildings. The vast majority of asbestos in buildings is chrysotile.
