Did Western MacArthur Use Asbestos?
Asbestos was once a common ingredient in all kinds of insulation products. Before knowledge of the risks was widespread, most insulation manufacturers used asbestos. Western MacArthur used asbestos in many of its products until the late 1970s.
Western MacArthur Company History
- The company that would become Western MacArthur was established in 1913 as a small pipe insulation manufacturing company called MacArthur Company.
- In 1967, MacArthur merged with Western Asbestos and became the Western MacArthur Company.
- After the merger, the company expanded substantially and began producing a full line of insulation products, most of which it manufactured with asbestos. This continued into the 1970s when many companies had to stop using asbestos due to health risks and lawsuits.
- In addition to making its own products with asbestos, Western MacArthur distributed Johns Manville construction products. Johns Manville was one of the largest manufacturers of asbestos construction materials.
- Western MacArthur faced lawsuits over asbestos exposure and resulting illnesses in workers. The costly lawsuits led to bankruptcy in 2002.
- Western MacArthur emerged from bankruptcy reorganization in 2004 as the MacArthur Company and with a $2 billion asbestos trust fund.
- MacArthur today is an employee-owned company that makes pipe insulation and other construction products without asbestos. MacArthur does not use asbestos in its products today.

Workers at Risk of Asbestos Exposure From Western MacArthur
Western MacArthur employees in the company’s manufacturing facilities were first in line to be exposed. These workers handled and worked near asbestos materials, which shed fibers and caused exposure.

- Instaladores de tuberías

Western MacArthur sold many of its products to the shipbuilding industry, where insulation on ships was vital. This included Marina de los EE. UU. ships and shipyards.
Buques de la Armada contained so many asbestos materials that veteranos now have very high rates of mesothelioma and other asbestos illnesses.
Exposure to asbestos in insulation was also a risk in homes. Homeowners with Western MacArthur or Johns Manville asbestos materials in their houses could be exposed when those materials deteriorate. They could also be exposed during repair, maintenance, or renovation work.
Western MacArthur Asbestos Lawsuits

He worked as a ship fitter’s mate and used insulated asbestos fabrics. He remembered and testified that the fabrics would often tore and relseased asbestos fibers. Jack was diagnosed with mesothelioma and ultimately won a $500,000 jury award.

Bankruptcy and Asbestos Trust Fund
