What Is Secondhand Asbestos Exposure?

How Secondhand Asbestos Exposure Occurs

Secondhand asbestos exposure — also known as secondary, paraoccupational, or take-home exposure — occurs when someone who does not work directly with asbestos is exposed to fibers transported from a workplace. The most common pathway is through contaminated work clothing. When a worker who has been exposed to asbestos comes home, microscopic fibers clinging to their clothing, hair, skin, shoes, and personal items are released into the home environment.

Family members are exposed through routine activities: greeting the worker with a hug, sitting near them, riding in the same vehicle, and especially laundering their work clothes. Shaking out asbestos-contaminated clothing before washing releases fibers into the air. The fibers then settle on household surfaces, become airborne again when disturbed, and can be inhaled by anyone in the home.

Documented Health Consequences

Medical literature has documented hundreds of cases of mesothelioma in individuals whose only known asbestos exposure was secondhand contact with an asbestos worker. Spouses who laundered contaminated clothing represent the largest group, but children, parents, siblings, and other household members have also been diagnosed. Some of these individuals were exposed as children and did not develop disease until decades later.

The Agency for Toxic Substances and Disease Registry (ATSDR) recognizes paraoccupational exposure as a documented cause of mesothelioma. Studies have shown that household contacts of asbestos workers have significantly elevated rates of mesothelioma and asbestosis compared to the general population.

Occupations Most Likely to Cause Take-Home Exposure

Workers in the most heavily asbestos-contaminated trades are most likely to carry significant quantities of fibers home. Insulators, shipyard workers, boilermakers, pipefitters, power plant workers, and construction workers in the pre-1980s era generated the highest take-home exposure risk for their families. Workers who did not have access to on-site showers or changing facilities, or who were not provided separate work clothing, posed the greatest risk to household members.

Many employers failed to provide these basic protections despite knowing about the hazards of asbestos exposure. Some asbestos manufacturers’ own internal documents show awareness that workers’ families were at risk, yet no warnings or protective measures were implemented.

Legal Rights of Family Members

Family members who developed mesothelioma through secondhand exposure have legal standing to pursue compensation from the asbestos product manufacturers whose products were the source of the take-home fibers. Courts across the country have recognized these claims. An experienced mesothelioma attorney can help identify the worker’s occupational exposure sources and pursue claims on behalf of affected family members.
