Asbestos exposure is a well-documented cause of serious health conditions, including mesothelioma, lung cancer, and asbestosis. While much attention has been given to occupational exposure, the dangers of secondhand or take-home exposure — especially in children—are often overlooked.
This article explores why children exposed to asbestos fibers brought home on work clothes may suffer worse lung damage than their occupationally exposed parents. It also highlights the scientific evidence supporting early-life vulnerability and the critical need for testing and monitoring children at risk.
Secondhand asbestos exposure occurs when individuals come into contact with asbestos fibers indirectly, often through contaminated clothing, tools, or equipment brought home by workers. This type of exposure is also referred to as “secondary” or “take-home” exposure.
Children of asbestos workers are particularly vulnerable because they may have been exposed to asbestos fibers in their homes for prolonged periods. Activities such as hugging a parent in work clothes, playing near or helping wash contaminated laundry, or even crawling on floors where asbestos dust has settled can result in significant exposure.

Longer Latency Period & Increased Risk: Asbestos-related diseases, such as mesothelioma and asbestosis, often develop 20 to 50 years after exposure. Because children exposed at an early age have more years ahead of them, they have a significantly higher lifetime risk of developing these diseases than adults who were exposed later in life (WHO).
A 1991 study on asbestos-exposed children found that:
The risk of mesothelioma increases exponentially over time (approximately the fourth power of latency). This means that for every additional decade a person lives after exposure, their risk of developing mesothelioma increases dramatically rather than linearly. For example, someone exposed as a child has a significantly greater lifetime risk compared to someone exposed in their 40s, simply because they have more years ahead for the disease to manifest.
Children exposed at ages 5 or 10 may still develop mesothelioma 60+ years later, well into old age. A long-term study of British asbestos workers found that latency periods can extend beyond five decades, particularly in cases of early-life exposure, reinforcing the long-term risk for children.
Their lifetime exposure risk far exceeds that of adults exposed in middle age.
Immature Respiratory Systems Increase Fiber Retention: Children’s lungs and respiratory systems are still developing, making them more susceptible to damage from inhaled asbestos fibers. Key risk factors include:
Higher breathing rates than adults, meaning they inhale more asbestos fibers per minute.
Greater fiber retention in lung tissue, leading to chronic inflammation and scarring
Longer Latency Period: Asbestos-related diseases, such as mesothelioma and asbestosis, have long latency periods—often 20 to 50 years. Because children are exposed at a younger age, they have a longer time for these diseases to develop compared to their parents, who may have been exposed later in life.
Higher Susceptibility to Fiber Retention: Studies have shown that children’s bodies may retain asbestos fibers more effectively than adults. Once inhaled, these fibers can lodge in the lungs or other tissues, causing chronic inflammation and scarring over time.
Cumulative Exposure: While occupational exposure is often limited to the workplace, children exposed secondhand may experience continuous, low-level exposure in their homes. This cumulative exposure can result in a significant fiber burden in their lungs, even if the exposure levels were lower than those experienced by their parents at work.
Delayed Diagnosis: Because children are not typically considered at risk for asbestos-related diseases, their symptoms may be overlooked or misdiagnosed. This delay in diagnosis can lead to more advanced disease progression by the time it is identified.
Research has consistently shown that secondhand exposure to asbestos can lead to serious health consequences. For example:
Increased Risk of Mesothelioma: Studies have confirmed that family members of asbestos workers are at an increased risk of developing mesothelioma, even with lower levels of exposure.
Non-Malignant Lung Damage: Conditions such as pleural thickening and asbestosis have been observed in individuals with secondhand exposure, including children.
Early-Onset Disease: Children exposed to asbestos early in life may develop asbestos-related diseases at a younger age than their occupationally-exposed parents, often with more severe symptoms.
Any type of exposure to asbestos – whether at home, work, or elsewhere – can lead to the development of an asbestos-related disease.
Given the significant risks associated with secondhand asbestos exposure, it is crucial to test and monitor the health of children who may have been exposed. Early detection of asbestos-related conditions can improve outcomes and allow for better management of symptoms.
Baseline Testing: Children of asbestos workers should undergo baseline testing to assess their lung health. This may include chest X-rays, pulmonary function tests, and other diagnostic tools to identify early signs of asbestos-related damage.
Regular Monitoring: Because asbestos-related diseases can take decades to develop, regular follow-up testing is essential. Monitoring can help detect changes in lung function or the development of pleural abnormalities over time.
Education and Awareness: Families of asbestos workers should be educated about the risks of secondhand exposure and the importance of testing. Parents should be encouraged to share their occupational exposure history with healthcare providers to ensure appropriate screening for their children.
Preventive Measures: While testing is critical, preventing further exposure is equally important. Families should take steps to minimize asbestos contamination in the home, such as:
Changing out of work clothes before entering the home.
Washing work clothes separately from other laundry.
Using protective equipment and following workplace safety guidelines.
The dangers of asbestos extend far beyond the workplace, impacting families and—most alarmingly—young children. Early-life exposure can result in severe lung damage, often worse than that of occupationally exposed adults.
If you or your family may have been exposed to asbestos, testing is essential. We offer free asbestos health tests for workers and their families. Call us today at 833-4-ASBESTOS to schedule a consultation.
