Second-Hand Asbestos Exposure — Family Members of Workers

Part of the Asbestos / Mesothelioma investigation

The short answer

Family members of asbestos workers who never set foot in a worksite have developed mesothelioma from asbestos fibers brought home on workers' clothing, hair, and skin — called para-occupational or household exposure. These cases have successfully produced multi-million-dollar verdicts.

How Household Asbestos Exposure Occurs

Para-occupational (household or take-home) asbestos exposure occurs when an asbestos worker carries fibers home on their work clothing, hair, skin, and in their vehicle. Family members who shook out, laundered, or even embraced an asbestos worker were exposed to fibers that became airborne in the home environment. Studies have documented mesothelioma incidence in household contacts of insulation workers, shipyard workers, and construction workers at rates significantly above the general population baseline. Wives and daughters who laundered heavily contaminated work clothing have the highest documented household exposure levels and the strongest legal claims.

Legal Claims for Secondary Exposure

Secondary exposure mesothelioma claims face an additional hurdle: establishing both the primary worker's occupational exposure (source of fibers) and the household exposure pathway. Attorney investigation reconstructs the primary worker's employment history — even if the worker is deceased — through Social Security records, union records, obituaries, and family testimony. The asbestos product manufacturers who supplied the primary worker's worksite are responsible for the household exposure claims under foreseeability theories: courts have found that manufacturers knew or should have known that contaminated work clothing would expose household members. Several landmark verdicts against W.R. Grace, Johns Manville, and other manufacturers have established household exposure as a fully compensable injury.

FAQ

Frequently Asked Questions

Mesothelioma is a cancer of the mesothelium — the thin membrane lining the lungs (pleura), abdomen (peritoneum), or heart (pericardium). It is distinct from lung cancer, which originates in the lung tissue itself. Mesothelioma is caused almost exclusively by asbestos exposure and does not arise from smoking. Lung cancer, while also caused by asbestos in some cases, is far more commonly caused by tobacco smoking. Both are compensable through asbestos trust funds and litigation, but mesothelioma claims typically produce higher compensation because the disease is more directly and singularly attributable to asbestos.
