Asbestos Exposure in the Aerospace & Aviation Industry
Workers in the aerospace and aviation industry were frequently exposed to asbestos due to its widespread use in manufacturing, maintenance, and repair processes. Asbestos was prized for its heat resistance, durability, and insulating properties, making it a key material in aircraft components, fireproofing systems, and engine insulation. However, these same properties also made asbestos fibers highly dangerous when disturbed, releasing microscopic particles into the air that workers unknowingly inhaled.
Aircraft mechanics and maintenance personnel faced some of the highest risks of direct exposure. Routine tasks such as replacing brake pads, removing engine gaskets, and handling insulation materials frequently disturbed asbestos-containing components. Blowing out brake dust, scraping off old gaskets, and cutting into fireproofing materials released asbestos fibers into the air, creating an inhalation hazard. Even simple maintenance activities, such as drilling or sanding near asbestos-containing insulation, could generate airborne fibers. Because aircraft systems often required extensive maintenance, workers were repeatedly exposed over time.
Manufacturing workers also faced significant exposure risks while producing aircraft components. Many handled raw asbestos materials or worked with asbestos-reinforced plastics, adhesives, and sealants. Tasks like cutting, sanding, or shaping asbestos-containing parts released fine asbestos dust, often in enclosed factory settings with limited ventilation. Assembly workers encountered asbestos in adhesives, coatings, and fireproofing materials, which were used to improve durability and heat resistance. Even those not directly handling asbestos—such as painters, welders, and electricians working nearby—were at risk of inhaling airborne fibers.
Beyond direct workplace exposure, asbestos also posed risks to family members through take-home contamination. Asbestos fibers could cling to workers’ clothing, hair, and tools, allowing them to unknowingly bring the hazardous material into their homes. Family members, especially those responsible for laundering work clothes, faced secondary exposure when shaking out or washing contaminated garments. Over time, this form of indirect exposure has been linked to mesothelioma, asbestosis, and other asbestos-related diseases, demonstrating that the dangers of asbestos extended far beyond the workplace.
During much of the 20th century, limited safety precautions were in place, and many workers were unaware of the health risks. Employers often failed to provide protective gear, ventilation systems, or decontamination procedures, leaving workers exposed for decades before the dangers became widely acknowledged. Today, retired aerospace and aviation workers continue to be diagnosed with asbestos-related illnesses, underscoring the long-term consequences of exposure in the industry.
