01.在管道连接器中使用石棉
为什么在管道连接器中使用石棉？
Asbestoswas a common additive to many products used in ductwork and HVAC systems, including ductwork connectors. The components of HVAC systems needed to be heat resistant and durable to keep the system operating smoothly.
整个房屋和建筑物的金属空气管将房间连接到HVAC系统。然后，空气通过管道，在整个房间内提供温暖或凉爽的空气。
Ductwork connectors absorb vibrations and noise caused by the airflow through ducting. These connectors needed to resist heat and be strong enough to keep the metal ducts secure. As a result, asbestos was often used in these connectors because of its fire resistance and durability.
Heating ducts and machinery were commonly connected and/or sealed with asbestos tape, fabric or paper. Research suggests asbestos tape used as a sealant or wrap around the ductwork could contain 15% or morechrysotile asbestos。

Asbestos Ductwork Connectors History At-a-Glance
- 其他名称：柔性管连接器，胶带管连接器，织物导管连接器，纸管绝缘，导管粘合剂，管道密封剂，管道包裹
- 制造年：1930s – 1980s
- Places Used:加热、通风和空调(HVAC)ystems
- Asbestos Use Banned:No
- Noteworthy Brands:Duro Dyne Corporation，，，，隔音板公司，，，，H.B. Fuller,Johns-Manville
Until the 1980s, many HVAC system components contained asbestos. This includes ductwork connectors, duct insulation, vibration dampeners, pipes, pipe insulation and more. As a result, many olderhomes，，，，buildings andschoolsmay have HVAC systems constructed with asbestos parts.
Exposure to these asbestos-containing materials can lead to health risks. Asbestos exposure causes万博专业版，，，，石棉病and other diseases.

管道连接器和其他HVAC系统组件通常含有石棉，直到1980年代。矿物具有足够的柔韧性，可以被编织成织物或用胶带密封管道。同时，石棉提供了耐用性和耐热性。
A variety of flexible asbestos duct connectors and sealers were available starting in at least the 1930s. For example, Duro Dyne Corporation produced the following asbestos-containing ductwork connectors:
- Duro Dyne Duct Sealer
- Duro-Metal-Fab Flexible Duct Connectors
- Econ-O-Fab Flexible Duct Connectors
- 初级柔性管连接器
其他几家公司还生产了含石棉的HVAC组件。其他石棉管道连接器和密封剂包括：
- Celotex Carey Asbestos Insulating Ducts
- Celotex Cary管道粘合剂（制造1940 - 1955）
- Celotex Carey Insulation Duct
- H.B. Fuller Duct Sealer 32-04
各种制造商produced asbestos ductwork connectors. Some of these companies also made otherasbestos-containing productsused in duct systems.
Their use of asbestos in these products put workers manufacturing the goods at risk of exposure. Those who worked with HVAC systems, homeowners and others also may have been exposed to friable asbestos.
03.管道连接器和石棉暴露
Who Is at Risk of Asbestos Exposure From Ductwork Connectors?
HVAC工人are among the most at risk of exposure from asbestos duct connectors. Installing or repairing ductwork connectors could cause asbestos fibers to become airborne. Other parts of HVAC systems also often contained asbestos. As a result, HVAC workers could disturb these other products while installing duct connectors.
Any damage, wear and tear or aging to any of the asbestos components in HVAC systems could lead to exposure.
其他建筑材料， 如ceiling tilesand绝缘材料，，，，may also contain asbestos. Workers should be cautious when interacting with these materials while servicing HVAC systems.
房主也可能风险接触石棉管道连接器。例如，用作管道连接器的石棉纸可以随着时间的推移而磨损。石棉纸可能会开始剥落，有可能导致周围地区的石棉灰尘。
04. Asbestos Lawsuits
Asbestos Lawsuits, Settlements & Other Compensation
Individuals exposed to asbestos ductwork connectors may be eligible forcompensation。If these individuals later develop an asbestos-related disease, such as mesothelioma, they may pursue lawsuits and不同类型的主张。
For instance, victims may be able to file an石棉诉讼反对产品导致曝光的制造商。
Individuals may also be eligible for other types of claims, such as anasbestos trust fund claim。For example, Johns-Manville manufactured asbestos-containing duct connectors. Those who worked with Johns-Manville asbestos products and developed a related illness may be able to file a claim with the company’s trust.
Individuals who develop an asbestos disease after exposure to asbestos ductwork connectors should talk to an experienced lawyer. An石棉律师can explain all of their legal options and handle the filing process.
Financial compensation can help mesothelioma victims and their loved onescover treatment expenses，，，，lost income and other related costs.
05. Asbestos Ductwork Connectors Removal
Safely Removing Asbestos Ductwork Connectors
Individuals should never attempt asbestos removal or encapsulation on their own. Asbestos tape and flexible duct connectors can easily release asbestos dust into the air when damaged or worn.
Individuals should also use caution if they have their air ducts cleaned. Some HVAC companies may recommend regular air duct cleaning every few years. However, the Environmental Protection Agency (EPA) warns knowledge around air duct cleaning is still in its early stages. It’s unclear if cleaning air ducts prevents health problems. As a result, it is too soon for the agency to make a clear recommendation on ductwork cleaning.
However, the agency warns anyone who has their air ducts cleaned should be cautious of the potential for asbestos. A professional should狗万10万提款 清洁之前。他们可以寻找石棉管道连接器，石棉绝缘and other asbestos components.
The EPA states any asbestos materials present should only be handled by specially trained contractors.
此外，在石棉修复过程中，石棉减少承包商应关闭并将HVAC系统与工作区域分离。职业安全与健康管理局（OSHA）建议用两层塑料密封管道和通风孔。这样可以防止鼓风机循环污染的空气。
The EPA and OSHA have variousregulations in place为了保护这些专业人员，其他工人和公众免于接触。
