01.含石棉的材料
What Are Asbestos-Containing Materials?
Asbestosis added to materials to increase resistance to chemicals, heat and fire. It may also add strength, durability and flexibility to products. During the 20th century,many industries used asbestos。From the 1930s to the 1970s, thousands of products contained asbestos. Some common types of asbestos-containing materials include insulation, ceiling and floor tiles, automotive brakes and talcum powder. Different石棉类型could be found in these products.
The wide use of asbestos in various products has caused exposure risks among workers, consumers and the general public. Common methods ofexposure to asbestos-containing materialsinclude household exposure,occupational exposureandsecondary exposure。
产品仍然包含石棉吗？
Many countries have禁止使用石棉, though it is still allowed in certain products in the United States.
In the U.S., some products are still allowed to contain asbestos in small amounts. For example, insulation materials may contain up to 1% asbestos. Older asbestos-containing products may also still be in use, including asbestos construction materials in buildings or asbestos parts in equipment. These past uses of asbestos continue to pose a risk.
Asbestos products are listed below with information on the items and materials, their uses and the risk posed to those exposed.
02.建筑产品
含石棉的建筑产品
Asbestos was often used in building products before 1980. As a result, many buildings in the U.S. were constructed with asbestos-containing materials. This puts construction workers, demolition workers and homeowners at risk of asbestos exposure.
粘合剂，粘合和密封剂
Asbestos was used in adhesives, bonding and sealers from the 1880s through the 1980s. Products such as mastic, putty, caulk and construction tape were all often made with asbestos. The mineral added durability and heat resistance. Because asbestos was a popular additive to these products, past uses remain in thousands of older homes and buildings today.
Asbestos Cement (Transite)
Asbestos cement, or transite, is a mixture of cement and asbestos fibers used to form a variety of products. Common transite products include pipes, roofing sheets, water tanks and flues. Asbestos cement was strong and durable, ideal for withstanding corrosion with a long lifespan. However, asbestos cement manufacturers were at high risk for developing mesothelioma and other asbestos-related diseases. Today, individuals may experience exposure from damaged and deteriorating asbestos cement products.
石棉感觉
Asbestos felt was used in roofing, flooring and paper mills from the early 1900s through the early 1990s. In construction, asbestos felt is used as a protective layer under flooring or roofing. At paper mills, asbestos felt was used to dry paper pulp. Papermill workers, construction workers and homeowners may have been exposed to asbestos felt. Today, felt underlayments may still be present in older homes and buildings.
Asbestos Sheets
Asbestos has been used in cement sheets since the early 1900s. The mineral was added to cement sheets to increase durability and temperature resistance. Asbestos cement sheets were especially popular because they were easier to handle than poured cement. As a result, these sheets were common in roofing and siding. Today, the United States does not allow asbestos cement sheet production. However, asbestos is still used in cement sheets produced in other countries that may be imported to the U.S. Construction workers and homeowners may also come into contact with asbestos cement sheets in older homes.
Asbestos Tiles
Asbestos was used in several types of tiling, primarily for floors and ceilings. The mineral provided durability, strength and heat resistance. Asbestos floor tiles contained asbestos from the 1920s to the 1970s. Asbestos ceiling tiles contained asbestos fibers from the 1950s to the 1980s. However, production dates may vary based upon the manufacturer. Some homes may still contain old asbestos tiles, posing a risk to homeowners.
Construction Materials
Various construction materials were frequently made with asbestos, such as roofing and siding. The mineral helped enhance durability and create structures that would withstand weathering, chemical erosion and fire. However, hazards occur when materials become damaged or crumble. When old buildings and homes are remodeled, renovated or demolished, asbestos fibers may release into the air.
Ductwork Connectors
Heating, ventilation and air conditioning (HVAC) systems use ductwork to deliver and remove air within a space. From the 1930s to the 1980s, many HVAC components contained asbestos. Asbestos was used in ductwork connectors, tapes, sealants and other components to provide durability and temperature insulation. Asbestos is no longer used in most of these parts today, but it may still be present in older HVAC systems.
垫圈
石棉垫片用于多个行业，包括建筑，锅炉，造船和制造。这些垫片用于在管道，阀门和其他部位之间创建紧密的密封。将石棉纤维掺入垫圈中，以抗热和化学物质。含石棉的垫圈一直生产到1980年代，但有些垫片可能仍存在于较旧的车辆和机械中。
Insulation
Asbestos was used for a variety of insulating materials. Loose-fill insulation in walls, spray-on insulation and block insulation contained asbestos. Although there are regulations in place to limit the use of asbestos, the mineral can still be used in insulation today as long as it does not exceed 1%. Homes, schools and other buildings may also have older asbestos insulation, which may contain higher amounts of asbestos.
Popcorn Ceiling Products
爆米花天花板和其他喷涂天花板coverings contained asbestos. The mineral provided durability, heat resistance and fire resistance. These asbestos-containing products were commonly used from 1945 to the early 1990s. Construction workers and homeowners may be in danger of asbestos exposure as these products age or degrade. Disturbing asbestos popcorn ceilings can also lead to exposure. For example, renovation and removal may release asbestos fibers.
Vinyl
石棉用于乙烯基产品以增强其耐用性和耐热性。矿物最常用于乙烯基产品，例如地板，板板和墙纸。石棉也经常被添加到这些产品的粘合剂和背景中。结果，去除乙烯基产品可以释放石棉纤维。石棉不再用于当今的乙烯基产品。但是，它可能仍然存在于较旧的房屋和建筑物中。
Zonolite Insulation
Zonolite是一种被石棉污染的ver石绝缘材料的广泛使用的品牌。它最常用于隔离阁楼。结果，建筑工人和房主可能已经接触到Zonolite绝缘的石棉。该材料今天不再生产。但是，个人可能仍在较旧的房屋和建筑物中与之接触。
03. Consumer Products
Consumer Products
Consumer products manufactured in the 1900s, as well as some made today, present asbestos exposure concerns. Contaminated consumer goods include slow cookers, paint and other popular items. These products put the population at risk of developing asbestos-related diseases.
Cigarette Filters
从1952年到1956年，Lorillard烟草公司在其Kent Micronite烟中使用了石棉纤维。包括矿物质以滤除烟雾刺激剂并提供更流畅的吸烟体验。但是，消费者可能在吸烟过程中吸入石棉纤维。在1952年至1956年间抽烟的人可能会暴露于石棉。
04.防火产品
Fireproofing and Fire-Resistant Products
由于石棉是一种已知的阻燃剂，因此它在各种防火和耐火产品中很受欢迎。含石棉的防火产品包括石棉布，消防块和消防安全装备。这些材料使消防员，建筑工人和许多其他行业处于接触风险中。这些含石棉的防火产品中的一些仍在积极生产。
Asbestos Textiles
石棉纤维经常被掺入纺织品中，以用于耐火衣服和毯子。为此目的，纤维温柔的石棉很容易编织成织物。消防员，急救人员和工业工人经常在日常工作中使用耐火的石棉手套和服装。石棉纺织品的制造业于1990年停产。但是，这些产品可能仍然存在于较旧的房屋，建筑物和工作地点。
05. Personal Care Products
Personal Care Products Containing Asbestos
Personal hygiene products and makeup may contain asbestos-contaminated talc. Asbestos and talc deposits are found near each other. Contamination of the talc may occur during mining. Individuals who use these asbestos-contaminated products may develop mesothelioma or another related disease.
Talcum Powder
Natural talc and asbestos deposits are often found near each other, which has led to contaminated talc in many consumer products. Asbestos-contaminated talc has been found in baby powder and cosmetics. Because of this dangerous contamination, thousands of consumers are taking legal action against manufacturers of talcum powder products.
Makeup
Many cosmetic products contain talcum powder as an ingredient. Talc can be easily contaminated with asbestos. As a result, eye shadows, blushes and other powder-based products may contain asbestos. Recent news has raised concerns regarding the presence of asbestos in children’s makeup. Stores such as Claire’s and Justice have recalled several contaminated products.
06. Transportation & Automotive Parts
Transportation and Automotive Products
运输和汽车行业多年来将石棉纳入其产品。汽车行业由于能够增强制动组件摩擦的能力而使用石棉。矿物也可以承受高温，以帮助设备和操作员免受火灾的侵害。但是，由于该行业成千上万的员工，许多员工已经并且继续存在石棉风险。
Once thought to be a miracle mineral, research has proven asbestos is dangerous. Exposure to asbestos products puts millions at risk of developing asbestos-related diseases, includingmalignant mesothelioma。Recognizing products known to contain the mineral and understanding the risks can help prevent exposure. Without a full ban on asbestos, people need to be aware of what products may contain the mineral.
