Long Beach Naval Shipyard: California's Asbestos Exposure History and 5 Compensation Paths

Long Beach Naval Shipyard exposed more than 17,000 workers to asbestos at its World War II peak, making Terminal Island one of California's most significant sources of occupational asbestos exposure across five decades of Pacific Fleet operations. From its commissioning in 1942 through its BRAC closure in 1997, LBNS relied on asbestos insulation throughout every major ship repair and maintenance operation—while workers in five high-risk trades handled the material daily in confined spaces with essentially no fiber controls or protective equipment until the mid-1970s.

What Are the Key Facts About Long Beach Naval Shipyard Asbestos Exposure?

• Long Beach Naval Shipyard operated on Terminal Island, adjacent to the Port of Long Beach, from 1942 until BRAC closure in 1997
• The shipyard employed over 17,000 workers at its WWII peak, all of whom encountered asbestos-containing materials in daily operations
• LBNS served as the primary Pacific Fleet maintenance facility, overhauling aircraft carriers, destroyers, cruisers, submarines, and auxiliary ships
• Asbestos was applied in over 300 shipboard applications at LBNS, including pipe insulation, boiler lagging, turbine covers, deck tiles, gaskets, and fireproofing compounds
• The five highest-risk trades at LBNS were insulators (laggers), boilermakers, pipefitters, machinists, and shipfitters working in asbestos-fireproofed compartments
• Engine rooms and boiler rooms presented the greatest exposure danger due to the concentration of asbestos insulation in sealed below-deck spaces
• The Navy began restricting new asbestos installations following the first OSHA regulations in 1971, but LBNS continued repairing older vessels with legacy asbestos through the 1980s
• California's proximity to the Pacific theater made LBNS a major World War II repair hub, generating some of the highest wartime asbestos exposure levels in the country
• Former LBNS veterans with mesothelioma may qualify for 100% VA disability ratings paying over $4,100 per month under current 2026 rates
• Civilian workers and veterans can simultaneously file trust fund claims against multiple asbestos manufacturers without filing a lawsuit
• California's statute of limitations gives mesothelioma patients one year from diagnosis to file a personal injury claim

What Made Long Beach Naval Shipyard a High-Risk Asbestos Site?

Long Beach Naval Shipyard's location and mission created conditions for extreme asbestos exposure. As the Pacific Fleet's primary West Coast maintenance depot, LBNS was responsible for keeping combat vessels operational throughout World War II, the Korean War, the Vietnam War, and the Cold War naval buildup. That mission required constant below-deck work in the most asbestos-dense environments aboard any ship.

Terminal Island's industrial layout concentrated thousands of workers in close proximity to repair bays and dry docks where ships were simultaneously stripped of old insulation and re-insulated with new asbestos-containing materials. Workers in adjacent trades—shipfitters, electricians, and painters working near insulators—inhaled fiber clouds generated by colleagues without ever directly handling asbestos themselves.

According to the Long Beach Naval Shipyard profile on WikiMesothelioma, LBNS was one of only a small number of Pacific Coast facilities with full dry dock capabilities, making it essential for hull repairs that exposed workers to asbestos in the most inaccessible and poorly ventilated shipboard spaces. The compressed wartime schedules of the 1940s meant workers applied and removed asbestos materials at maximum speed with no respiratory protection, no engineering controls, and no industrial hygiene monitoring of any kind.

"What made Long Beach and shipyards like it so dangerous wasn't just the volume of asbestos—it was the confined spaces. Below-deck compartments were essentially sealed chambers where a single insulator cutting pipe lagging could contaminate the air for an entire shift. Every worker in that compartment was breathing the same fiber cloud." — Larry Gates, Senior Advocate specializing in military and shipyard exposure cases, Danziger & De Llano

Which Trades Faced the Highest Asbestos Exposure at LBNS?

Five occupational groups at Long Beach Naval Shipyard consistently received the heaviest asbestos fiber doses over the course of a working career.

Insulators and Laggers

Insulators—also called laggers—applied asbestos pipe lagging and boiler insulation directly as part of their core job duties. The Occupational Asbestos Exposure Quick Reference at WikiMesothelioma documents that insulation workers face a mesothelioma mortality rate 46 times higher than the general population—the highest of any trade classification. At LBNS, laggers mixed asbestos-containing cements, cut asbestos cloth and block, and packed lagging onto hot steam pipes in engine rooms where ventilation was minimal. Fibers they generated remained suspended in the compartment air for hours after the work was complete.

Boilermakers

Boilermakers at LBNS installed, repaired, and replaced boiler systems entirely encased in asbestos insulation. Removing old boiler lagging to access underlying equipment released dense fiber clouds that filled sealed engineering spaces. During combat-damage repairs—particularly urgent during the Korean War and Vietnam eras—boilermakers worked through asbestos dust clouds without delay or respiratory protection to return ships to operational status on compressed timelines.

Pipefitters and Plumbers

Every warship passing through LBNS carried miles of steam, fuel, and water pipe wrapped in asbestos insulation. Pipefitters cut, stripped, and replaced asbestos-insulated pipe throughout their careers—generating fine respirable fibers with every cut. The below-deck environments where this work took place offered no natural ventilation, meaning fiber concentrations built throughout each work shift.

Machinists

LBNS machinists operated lathes, grinders, and precision tools in close proximity to asbestos-containing gaskets, packing materials, and machinery insulation. Grinding operations on asbestos components—including asbestos gaskets used in engine room equipment—generated the finest respirable particles that penetrated deepest into the lung tissue. Machinists' proximity to this material throughout a career created significant cumulative fiber burden.

Shipfitters and Structural Workers

Shipfitters worked in compartments where asbestos fireproofing had been sprayed onto surrounding bulkheads and overheads. Welding, grinding, and cutting near asbestos-fireproofed surfaces disturbed fibers that had been dormant in the spray coatings, releasing them into the work environment. Even structural workers who had no direct contact with asbestos products could receive significant fiber exposure as bystanders to other trades' work.

"The misconception I hear most often is that only workers who physically touched asbestos products were harmed. At LBNS, a shipfitter welding steel near a lagger's work zone was breathing the same air. Secondary and bystander exposure contributed to thousands of California mesothelioma cases from shipyard work." — Larry Gates, Senior Advocate, Danziger & De Llano

When Was Asbestos Used at Long Beach Naval Shipyard and When Did It Stop?

Long Beach Naval Shipyard's asbestos use followed a consistent trajectory from mass adoption to phased removal over its 55-year operational history.

1942–1945: Wartime Commissioning and Maximum Throughput. LBNS was commissioned in 1942 specifically to support the Pacific War effort. During these years, workers applied asbestos to virtually every vessel passing through the facility under wartime urgency. Manufacturers including Johns-Manville, Owens Corning, and Pittsburgh Corning supplied LBNS with asbestos insulation products in massive quantities. No warnings accompanied these shipments, and no protective equipment was provided to workers.

1946–1970: Cold War Fleet Maintenance. After WWII, LBNS transitioned to its Cold War mission of maintaining Pacific Fleet combat readiness. Korean War-era repairs in the early 1950s drove peak exposure for the generation of workers who are today in their 70s and 80s. Asbestos use continued at essentially full scale through this period as new procurement contracts maintained the supply of asbestos insulation products.

1971–1985: OSHA Standards and Transitional Period. OSHA's first asbestos permissible exposure limit in 1971 began restricting new asbestos installations aboard vessels. However, LBNS continued servicing older ships still carrying decades of legacy asbestos—meaning workers through the mid-1980s faced meaningful secondary exposure during routine maintenance operations. The transition was gradual, not sudden, and workers were still encountering asbestos regularly through this period.

1986–1997: Managed Abatement Through Closure. By the late 1980s, asbestos abatement crews handled any discovered legacy asbestos under OSHA-compliant controls. However, even carefully managed abatement carries regulated residual exposure risks. The Occupational Safety and Health Administration continues to set strict exposure limits for abatement workers today, reflecting that even controlled asbestos removal carries measurable fiber risk.

What Diseases Are Former LBNS Workers Developing?

Former Long Beach Naval Shipyard workers who inhaled asbestos fibers face a spectrum of serious asbestos-related conditions, each with distinct legal and financial implications.

Mesothelioma is the most serious consequence of shipyard asbestos exposure. Malignant mesothelioma affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal mesothelioma), or heart (pericardial mesothelioma). According to the National Cancer Institute, mesothelioma has one of the strongest documented causal links to asbestos exposure of any cancer—and shipyard workers are among the highest-risk populations. The 20-to-50-year latency period means workers exposed at LBNS in the 1950s and 1960s are receiving diagnoses now.

Asbestosis is a progressive scarring of lung tissue caused by lodged asbestos fibers. Unlike mesothelioma, asbestosis is a non-malignant condition, but it causes severe respiratory impairment, reduced lung capacity, and significantly reduced quality of life. The ATSDR Asbestos Toxicological Profile documents that asbestosis incidence correlates with cumulative fiber dose—making high-volume shipyard workers among the most affected populations.

Asbestos-Related Lung Cancer carries similar prognosis to mesothelioma and often goes unrecognized as asbestos-related. Workers who smoked and also had shipyard asbestos exposure face a multiplicative—not merely additive—increase in lung cancer risk compared to either exposure alone.

Pleural Plaques and Pleural Effusion are non-malignant changes to the pleural lining that indicate significant lifetime asbestos exposure. While less severe than mesothelioma or lung cancer, these conditions confirm asbestos exposure history and may support compensation claims.

Are Veterans Eligible for VA Benefits from LBNS Asbestos Exposure?

Military veterans who served at Long Beach Naval Shipyard may qualify for VA disability compensation for asbestos-related diseases including mesothelioma, asbestosis, and asbestos-related lung cancer. The U.S. Department of Veterans Affairs recognizes asbestos as a service-connected hazardous material, and LBNS is among the documented high-exposure naval facilities.

Under current 2026 VA compensation rates, a 100% service-connected disability rating for mesothelioma pays $4,158.17 per month for a single veteran, with higher rates for veterans with dependents. The PACT Act of 2022 expanded the scope of toxic exposure claims and strengthened the presumptive service connection for veterans with asbestos-related diseases from documented exposure sites like LBNS.

Surviving spouses of veterans who died from asbestos-related diseases may qualify for Dependency and Indemnity Compensation (DIC), which pays over $1,600 per month for the surviving spouse regardless of the veteran's disability rating at time of death.

"The PACT Act changed the landscape for veterans with asbestos diseases. It strengthened presumptive service connection, which means qualifying veterans no longer need to prove exposure on a case-by-case basis the way they once did. If you worked at Long Beach Naval Shipyard in the trades we've described and you have a mesothelioma or asbestosis diagnosis, you have a strong VA claim." — Larry Gates, Senior Advocate, Danziger & De Llano

What Are the 5 Compensation Paths for Former LBNS Workers?

Former Long Beach Naval Shipyard workers and their families have access to five distinct legal and financial compensation mechanisms depending on their employment status, diagnosis, and surviving family circumstances.

1. VA Disability Benefits. Military veterans who served at LBNS and developed mesothelioma, asbestosis, or related disease can file a VA disability claim through the Department of Veterans Affairs. A 100% rating for mesothelioma currently pays $4,158.17 per month. Veterans can pursue VA benefits simultaneously with trust fund claims and lawsuits—these pathways are not mutually exclusive.

2. Asbestos Trust Fund Claims. Multiple asbestos manufacturers who supplied LBNS with insulation products have established bankruptcy trusts to compensate victims. Workers may qualify for simultaneous claims against the Johns-Manville Trust, Owens Corning/Fibreboard Trust, Pittsburgh Corning Trust, USG Trust, W.R. Grace Trust, and others based on documented product use at the shipyard. The combined asbestos trust fund system holds over $30 billion in current reserves. Trust fund claims require no lawsuit and are processed separately from any litigation.

3. Personal Injury Lawsuits. Former workers (or their estates) can file personal injury or wrongful death lawsuits against asbestos product manufacturers—not against the Navy itself, which has sovereign immunity protections. California's one-year statute of limitations for asbestos personal injury claims runs from the date of diagnosis, not from the date of exposure. Our mesothelioma attorney directory can connect LBNS workers with California-licensed mesothelioma attorneys who work on contingency with no upfront costs.

4. Workers' Compensation. Civilian LBNS employees who developed asbestos disease may be eligible for California workers' compensation benefits, including medical expense coverage and wage replacement. California has specific provisions for latent occupational diseases that allow claims to be filed years after initial exposure.

5. DIC Benefits for Surviving Spouses and Dependents. Spouses and children of veterans who died from service-connected asbestos disease can file for Dependency and Indemnity Compensation through the VA. DIC is paid monthly regardless of the veteran's income or the family's financial situation, and surviving spouses may also qualify for Survivors Pension if the veteran served during a wartime period.

How Does Long Beach Naval Shipyard Compare to Other California Asbestos Sites?

Long Beach Naval Shipyard was one of several significant California asbestos exposure sites, but its concentration of shipyard trades in a single location made it particularly impactful. Other major California naval facilities—including Hunters Point Naval Shipyard in San Francisco Bay and Mare Island Naval Shipyard in Vallejo—followed similar asbestos use patterns.

California's broader industrial history also includes significant asbestos exposure at oil refineries along the Houston Ship Channel equivalent on the West Coast—the LA Basin petrochemical corridor—as well as naturally occurring asbestos in 42 of California's 58 counties from serpentinite rock formations. Workers who had both shipyard and subsequent industrial careers may have faced additive lifetime fiber exposures from multiple sources.

The Shipyard Exposure Index at WikiMesothelioma provides comparative documentation of major US shipyard facilities and the specific exposure patterns documented at each, including vessel types serviced, predominant trades present, and peak employment periods.
