Western MacArthur specialized in manufacturing and distributing construction materials, many of which contained asbestos until the late 1970s. What sets WM apart is that a significant number of its customers were other asbestos companies.
By 2002, their legal liabilities had grown unmanageable, and WM filed for Chapter 11 bankruptcy protection.
The Western MacArthur Asbestos Personal Injury Trust was formed in 2004 and funded with $2 billion to compensate victims exposed to asbestos by WM.
Like most asbestos trust funds, the WM trust only pays a percentage of each claim to ensure enough funds remain for all current and future victims.
The current payment percentage is 51.1%, much higher than most trusts.

Key Information
- WM not only manufactured asbestos products but acted as a distributor for other asbestos companies.
- The WM trust charges a $250 filing fee for every claim submitted for review. This fee is refunded if the claim is successful.
- WM used asbestos to make various construction products, which were used on land and in ships. The U.S. Navy widely used the company’s insulation products.
- The top occupations exposed to WM asbestos products were construction and shipyard workers and Naval personnel.
Western MacArthur & Asbestos Exposure
Created through a merger of Western Asbestos and the MacArthur Company in 1967, Western MacArthur became a large manufacturer and distributor of asbestos products.
Both of its parent companies were already involved in the asbestos market. Western Asbestos was a distributor of asbestos products, primarily those made by Johns Manville. Its primary clients were shipyards and shipbuilders.
The MacArthur Company also distributed Johns Manville construction products and began manufacturing its own asbestos products in the 1950s.
After the merger, the Western MacArthur product line included roofing, insulation, heating materials, air-conditioning parts, and ventilation products. WM also continued to act as a distributor for Johns Manville.
Western MacArthur added asbestos to their products until the late 1970s, valuing it for its heat, fire, and chemical resistance.
WM’s insulation products were particularly popular and widely used in building and ship construction. Much of this asbestos insulation is still in place in structures nationwide.
Even though the company filed for bankruptcy protection in 2002, it is still one of the nation’s largest manufacturers and suppliers of insulation materials.
It also sells roofing, fire protection, and fiber-reinforced plastic products. There are more than 35 WM locations in the U.S.

Not knowing the risks of asbestos at the time, workers who interacted with Western MacArthur products inadvertently exposed their loved ones to asbestos by bringing asbestos fibers into their homes.
Secondary, or indirect, asbestos exposure is most common in the children and wives of asbestos workers.
Asbestos fibers would cling to clothes, furniture, carpeting, and bedding and were often transferred through contact with workers themselves when returning home.
Women — who washed their husbands’ contaminated work clothes — faced the highest risk of in-home secondary exposure.
Mounting Asbestos Lawsuits Against Western MacArthur
Because of the prevalence of Western MacArthur products, many lawsuits were filed against the company, its predecessors, and associated entities.
Western MacArthur and their insurance company, USF & G, did their best to settle claims out of court for decades. When they failed, they were taken to court by their victims. Some examples include:
Kaminski vs Western MacArthur Co. (1985)
The wife of a deceased military veteran claimed her husband’s mesothelioma diagnosis was a result of working as a shipbuilder.
Because his interactions while on the job were with Western Asbestos products, the Kaminski family received a judgment in their favor for personal injuries and loss of consortium and were awarded $500,000.
Hughes vs Western MacArthur Company (1987)
The wife of a deceased employee of Western MacArthur (known as Western Asbestos during his employment) filed a wrongful death claim, which was initially denied but was granted upon appeal.
Associated Companies
Western MacArthur was formed in 1967 by the merger of the Western Asbestos Company and the MacArthur Company.
In addition to manufacturing asbestos products, WM distributed asbestos products made by others, including Johns Manville. Many of their customers were other asbestos companies.
Companies Associated With Western MacArthur:
- Bechtel Corporation (customer)
- Johns Manville (WM distributed their products)
- Kaiser Aluminum (customer)
- Owens Corning (customer)
High-Risk Jobs Associated With Western MacArthur
Western MacArthur was one of the largest manufacturers and distributors of asbestos products in the U.S. They made and sold popular asbestos products — like pipe coverings and insulation — and distributed products made by other asbestos companies, like Johns Manville.
Its wide exposure range has impacted hundreds of occupations and sites across the United States.
Fact
In addition to WM employees, anyone who worked in a job or location where they were regularly exposed to WM products (or products it distributed) is also at risk of developing an asbestos-related illness.
Jobs at Highest Risk for Asbestos Exposure
- Construction Workers
Those who installed or removed Western MacArthur insulation products in any form run the risk of asbestos-related illnesses, including mesothelioma.
All Western MacArthur insulation products produced until the late 1970’s included asbestos. Many of their other construction products, like joint compounds and adhesives, also contained asbestos.
- Shipyard Workers
Western MacArthur insulation and cloth were widely used in shipyards. These products were used to build, maintain, and repair ships.
Workers were never instructed to wear protective face or body coverings when working with these products, leaving them vulnerable to contact with asbestos fibers in the environment.
- Naval Personnel
Sailors who worked and lived aboard U.S. Navy vessels were at a high risk of exposure to Western MacArthur insulation.
The company’s products were widely used aboard naval vessels, and many Navy personnel were exposed during their duties, even if they were not directly responsible for handling asbestos-containing materials.
Simply being in the area when asbestos materials were damaged, installed, repaired, or otherwise handled likely put them in contact with airborne asbestos fibers.
Other At-Risk Jobs
- Boiler operators/technicians
- Coppersmiths
- Electricians
- Estimators
- Foundry workers
- Hostlers
- Insulators
- Longshoremen
- Masonry workers
- Oilers
- Plumbers
- Riggers
- Sales personnel
- Truck drivers
- Warehouse workers

The Formation of the Western Asbestos Settlement Trust
The Western MacArthur Asbestos Trust was formed in 2004 with $2 billion set aside to compensate victims harmed by WM or its parent companies, Western Asbestos and the MacArthur Company.
The WM Trust charges a filing fee of $250 per claim. This fee is refunded if the claim is successful, but unsuccessful claimants cannot recover this money.
The trust recognizes eight scheduled conditions as eligible for financial compensation.
Understanding the Different Review Processes
Victims seeking to file a claim against the WM trust must first choose the most suitable review process from the three options offered: matrix, individual, or extraordinary.
The trust generally handles claims on a first-in, first-out (FIFO) basis. If you’re eligible to file, an experienced asbestos attorney can help you choose the appropriate review process for you.
Matrix Review
A matrix review (MR) is the fastest and most straightforward way to receive compensation from the WM trust.
An MR claim must meet all the criteria defined by the Case Valuation Matrix. This review type is best for those with complete documentation who need payment quickly to meet pressing expenses resulting from their diagnosis.
Individual Review
Individual review (IR) is a good option for those who do not meet the criteria for an MR claim or who otherwise want to have their claim more closely and individually evaluated.
IR review generally takes longer but often — though not always — leads to a higher settlement amount. IR review is suitable for those with less complete or more ambiguous documentation or who want to maximize their potential settlement amount.
Extraordinary Review
Only those whose asbestos exposure was caused primarily by Western MacArthur (80% or more of total exposure) or who have substantial special damages are eligible for extraordinary review (ER).
A successful ER claim often yields the highest possible settlement value, but those applying must meet a very narrow and stringent set of circumstances.
Exigent Hardship
Claimants who make a successful exigent hardship claim move to the head of the FIFO claim payment queue.
Claimants making a hardship claim must show:
- A need for immediate financial assistance based on total expenses versus all available sources of income
- A causal connection between their financial situation and their diagnosis of an asbestos-related disease
Western MacArthur Lawsuit Settlement Payouts and Percentages
The WM trust only pays a percentage of each claim’s settlement value to ensure enough funds remain to compensate all current and future claimants.
Fact
The current payment percentage is 51.1%, much higher than most trusts. The trustees review and update the payment percentage every few years.
Source: Western Asbestos Settlement TrustWestern MacArthur Trust settlements vary, and average settlement values are listed and categorized by type of illness, associated brand, and location as the values differ.
Base Case Values represent the initial valuation of a claim, established before considering any specific situational adjustments.
These values are then modified based on several factors, including:
- Age
- Level of exposure
- Whether the injured person is living during the claim filing or litigation
- The estimated costs for their medical care and funeral expenses

Eligibility Requirements for the Western Asbestos Settlement Trust
To receive a payment from the Western Asbestos Settlement Trust, claimants must first prove their eligibility through strict documentation requirements.
These requirements fall into two primary categories: medical and exposure.
“Victims looking to file a claim against an asbestos company should move quickly. The statute of limitations in asbestos claim cases varies, but it’s never long, typically 2 to 3 years following diagnosis. An experienced asbestos lawyer can help eligible claimants monitor critical deadlines and meet all filing requirements. ”
– Daniel Wasserberg, Attorney

Medical Requirements
The requirements to prove medical eligibility vary depending on which of the eight scheduled conditions the claimant is diagnosed with.
However, there is some overlap, including:
- Diagnosis of one of the covered conditions by a physician or pathologist
- Testing and imaging that supports the diagnosis like:
- X-ray
- CAT scan
- Pleural testing
- Pathology report
- 10-year latency
Exposure Requirements
Many documents are needed to prove the dates and duration of the exposure. Claimants will also need to prove that they or someone close to them worked in one of the traditional occupations approved by the trust.
Some examples of potential documentation include:
- Adoption records
- Affidavits
- Depositions
- Military records
- Paystubs
- Railroad records
- Social Security records
- Union records or dispatch slips
- Witness statements
“Getting legal assistance can help reduce the stress of the claims filing process. A good lawyer can help you navigate the trust, gather evidence and documentation, and work to maximize your potential compensation.”
– Daniel Wasserberg, Attorney

Often, asbestos victims are too ill to handle the claims process on their own. In many cases, due to the fast-moving nature of asbestos illnesses, victims may pass away before or during filing.
However, the death of an asbestos victim does not negate the responsibility of asbestos companies to compensate them or their heirs. Family members filing on behalf of a loved one may also seek legal help.
An asbestos attorney can help ease the burden placed on dependants and caregivers already struggling with the mental, emotional, and financial burdens of serious illness, allowing you to keep your focus where it belongs: on healing.
