Asbestos is a group of naturally occurring fibrous minerals valued for their heat resistance, strength, and insulating properties. It was widely used in various industries, including construction and shipbuilding. Its durability and fire-retardant qualities made it an ideal material for Navy ship construction and maintenance for decades.
Widespread Use on Navy Vessels
Asbestos was used extensively in United States Navy vessels, from aircraft carriers to submarines, primarily from the 1930s through the 1980s. Its use stemmed from exceptional thermal insulation, fireproofing, and corrosion resistance, desirable in maritime environments. Shipyards and repair facilities used asbestos materials during new builds and routine maintenance.
Commonly found in engine and boiler rooms, the material insulated pipes, boilers, turbines, and pumps to manage extreme temperatures. Asbestos lagging, a protective covering, wrapped around pipes and ducts throughout ships to maintain temperature. Gaskets, valves, and packing materials in mechanical systems also contained asbestos fibers for their ability to withstand high pressures and temperatures.
Beyond insulation, asbestos fireproofed bulkheads, decks, and electrical components like wiring insulation and circuit breaker panels. Naval personnel in engineering, damage control, and maintenance roles routinely worked near these materials. Exposure occurred during routine operations, repairs, and especially during overhaul periods when asbestos materials were disturbed or removed.
Health Impacts of Asbestos Exposure
Exposure to asbestos fibers can lead to several serious diseases, with symptoms often appearing decades after initial exposure. Mesothelioma is a rare and aggressive cancer primarily affecting the thin lining of the lungs (pleura), abdomen (peritoneum), or heart (pericardium). Symptoms like shortness of breath, chest pain, and unexplained weight loss emerge 20 to 50 years following exposure.
Asbestosis is a chronic, non-cancerous lung disease characterized by scarring of the lung tissue (fibrosis), which reduces lung elasticity. This scarring makes breathing difficult and can lead to a persistent dry cough and shortness of breath, particularly during physical activity. The latency period for asbestosis ranges from 10 to 40 years after the first significant exposure.
Asbestos exposure also increases the risk of developing lung cancer, distinct from mesothelioma, primarily affecting the lung tissue itself. This cancer presents with symptoms such as a persistent cough, chest pain, coughing up blood, and unexplained weight loss. The time between asbestos exposure and diagnosis of lung cancer ranges from 10 to 30 years.
Pleural plaques are areas of fibrous thickening on the pleura, the lining around the lungs, and are the most common radiographic sign of asbestos exposure. While benign and asymptomatic, their presence confirms past asbestos exposure and may indicate an increased risk for other asbestos-related diseases. These plaques develop within 10 to 20 years after exposure.
Recognizing Exposure and Seeking Medical Attention
Individuals with a history of Navy service, particularly those involved in ship repair or engine room duties, should watch for symptoms of asbestos-related disease. Common indicators include persistent shortness of breath, a chronic cough that does not resolve, and unexplained chest pain or tightness. Fatigue and unintentional weight loss also warrant medical evaluation.
Consulting a healthcare provider, especially one experienced in occupational lung diseases, is a crucial step if any of these symptoms appear. Providing a detailed occupational history, including specific naval assignments, dates of service, and duties performed, is helpful for diagnosis. This information assists the doctor in assessing asbestos exposure.
Diagnostic methods for asbestos-related conditions include imaging tests, such as chest X-rays, which reveal pleural plaques or diffuse pleural thickening. A computed tomography (CT) scan of the chest provides images of lung abnormalities and pleural changes. Pulmonary function tests measure lung capacity and airflow, helping to identify impaired lung function.
A definitive diagnosis of diseases like mesothelioma or asbestosis requires a biopsy, where a tissue sample is taken for examination. This procedure helps confirm the presence of asbestos fibers or specific cellular changes characteristic of these conditions. Early detection, while challenging due to long latency periods, allows for timely management of symptoms and potential treatment options.
Support and Legal Avenues for Veterans
Navy veterans diagnosed with asbestos-related diseases have access to support and legal avenues. The Department of Veterans Affairs (VA) provides disability compensation for conditions determined to be service-connected, meaning they are a direct result of military service.
Veterans also have access to VA healthcare benefits, which cover medical treatment for service-connected conditions. This includes specialized care for respiratory illnesses and cancer treatments. Navigating the VA claims process is complex, and veterans benefit from assistance from accredited veterans service organizations.
Beyond VA benefits, legal options are available against asbestos manufacturers who produced the materials used in Navy vessels. These lawsuits aim to recover compensation for medical expenses, lost wages, and and pain and suffering. Many asbestos manufacturers established trust funds through bankruptcy proceedings to compensate victims, providing another avenue for compensation.
Veterans support organizations and legal firms specializing in asbestos exposure offer guidance on both VA claims and legal actions. These resources help veterans pursue compensation and care for illnesses linked to their their service. They provide assistance in gathering necessary documentation and navigating complex legal and administrative procedures.
