A West Virginia appeals court has upheld workers’ compensation survivor benefits for the widow of an industrial electrician who died of mesothelioma. The November 10, 2026 decision examines how occupational asbestos exposure can be established when a worker spent decades repairing equipment for more than one employer.
In Adams Manufacturing Company, Inc. v. Mildred J. Cantrell, the Intermediate Court of Appeals of West Virginia affirmed an award of dependent benefits to Mildred Cantrell following the death of her husband, Spencer T. Cantrell.
Decades of work repairing mining equipment
Spencer Cantrell worked as an industrial electrician and welder for J&S Mining, later known as Mountaineer Mining Service, from 1974 to 1992. He then worked for Adams Manufacturing from 1993 to 2012. His duties included building, rebuilding, and repairing mining equipment, including electrical starters and controls.
Cantrell described work with materials associated with electrical equipment, including packing, cables, and brakes, and extensive work on equipment made by Joy Manufacturing. He was diagnosed with malignant mesothelioma in 2020 and died on October 31, 2020. His widow, Mildred Cantrell, sought workers’ compensation dependent benefits.
Why was the claim initially denied?
The claim administrator denied benefits in July 2021, citing insufficient information about the date and location of the worker’s last asbestos exposure and the connection between the disease and his employment.
The case proceeded through administrative and appellate reviews. In 2024, the Intermediate Court of Appeals determined that the claim had been evaluated under occupational-pneumoconiosis standards rather than the occupational-disease provisions relevant to mesothelioma. Following further proceedings, the Workers’ Compensation Board of Review awarded dependent benefits in March 2026. Adams Manufacturing appealed.
How was the historical asbestos exposure investigated?
The record included Spencer Cantrell’s own statements and testimony about the work he performed, along with testimony from his brother, Jack Cantrell, who had worked alongside him. His brother described removing and replacing rope-like packing and blowing dust from electrical boxes during repairs.
Investigators also considered a historical Joy Manufacturing parts catalog identifying asbestos packing and packing glands for certain equipment, as well as interrogatory responses from Joy Technologies in separate asbestos litigation acknowledging that some mining machines may have contained asbestos-containing packing, brake pads, or electrical cables.
Those records did not establish that every piece of mining equipment contained asbestos. They supplied historical context that the Board considered together with testimony about Cantrell’s work and medical evidence connecting occupational asbestos exposure to his mesothelioma.
What if an employer says asbestos was not present?
Adams Manufacturing disputed exposure at its facility and relied in part on an affidavit from a former shop foreman who said he was unaware of asbestos there. The Board did not regard that statement as conclusive, and the appeals court noted that it did not cover Cantrell’s entire employment period.
A witness’s lack of knowledge about asbestos at a workplace is not necessarily proof that asbestos-containing materials were never used there. Conversely, missing records or uncertain memories do not prove exposure. An investigation must evaluate work histories, witness accounts, equipment records, and medical evidence together.
Can exposure at several employers support a claim?
Adams argued that Cantrell had potential asbestos exposure at earlier employers and elsewhere. The court rejected the proposition that the claim required proof that Adams was the exclusive source of exposure.
Applying West Virginia occupational-disease law, the court explained that exposure can occur across multiple employers and that the last employer where qualifying exposure occurred may bear responsibility under the applicable workers’ compensation framework. The court concluded that sufficient evidence supported the Board’s determination and affirmed dependent benefits.
This is a West Virginia workers’ compensation ruling. It does not determine rights under New York law, civil asbestos lawsuits, or asbestos bankruptcy trust procedures.
What can families learn from this decision?
Mesothelioma can develop decades after exposure. By the time someone is diagnosed, workplaces may have closed, employers may have changed names, and equipment records may be difficult to locate.
The decision illustrates why a complete employment history matters. A job title alone may reveal less than the particular equipment repaired, materials removed or replaced, maintenance methods used, and coworkers who witnessed the work. Historical catalogs, manufacturer documents, and witness testimony can help evaluate those details.
The outcome of any individual claim depends on the evidence and the law that applies.
