Asbestos Exposure at Charleston Naval Shipyard: What Workers and Families Need to Know

Your Exposure at Charleston Naval Shipyard May Have Caused Your Disease — Act Within 3 Years of Diagnosis

Civilian workers at Charleston Naval Shipyard reportedly worked alongside asbestos-containing pipe insulation, boiler packing, spray fireproofing, and dozens of other products for decades. The shipyard operated on the Cooper River in North Charleston, South Carolina, from 1901 until its 1996 closure under BRAC. Pipe laggers, boilermakers, pipefitters, electricians, painters, welders, carpenters, and laborers allegedly handled or worked near products supplied by Johns-Manville, Owens-Illinois, Combustion Engineering, Armstrong Cork, and others — companies now facing liability for mesothelioma, asbestosis, and asbestos-related lung cancer diagnoses still emerging today.

Federal maritime law gives you 3 years from diagnosis to file suit. The clock starts the moment your diagnosis is confirmed. Manufacturer trust fund claims run on separate deadlines and may provide additional compensation. Both options may apply to your case simultaneously.

Charleston Naval Shipyard: Operational History and ACM Use

Charleston Naval Shipyard ran for nearly 95 years as one of the Atlantic Fleet’s primary shipbuilding and repair installations. The facility employed tens of thousands of civilian tradespeople at peak operations, working alongside Navy personnel on vessel construction, overhaul, and fleet maintenance.

Key operational periods:

World War II construction and fleet expansion
Post-war overhaul cycles (1945–1980s)
Cold War submarine maintenance and repair programs
Nuclear-powered vessel refitting (1960s–1990s)

Multiple generations of Lowcountry families worked the yard. Asbestos-related disease clusters — mesothelioma, asbestosis, lung cancer — continue to be diagnosed among former workers and, in some cases, their family members who allegedly received secondary exposure from contaminated work clothing.

Asbestos-Containing Materials Allegedly Present at Charleston

Navy procurement specifications and MIL-SPEC standards made asbestos the default insulation material across shipboard systems throughout most of the twentieth century. Steam propulsion plants, fire suppression requirements, and federal purchasing standards kept these products in continuous use.

ACMs allegedly used at Charleston included:

Pipe covering and block insulation on steam, fuel, and chilled water lines
Boiler packing, gaskets, and refractory brick in propulsion plant spaces
Spray fireproofing — Monokote and Zonolite — applied to structural surfaces aboard vessels
Transite board and Gold Bond asbestos-cement in bulkheads, deckhouses, and fire barriers
Thermal insulation blankets in engine rooms and fire rooms
Deck tile and chrysotile-containing adhesives in crew berthing and working spaces
Asbestos-wrapped conduit and insulated cable in electrical compartments
Asbestos cement in pump packing and valve components

Manufacturers Allegedly Supplying These Products

Litigation records and government procurement documents allege these manufacturers supplied ACMs to federal shipyards including Charleston while allegedly possessing internal knowledge of asbestos health hazards:

Johns-Manville — pipe insulation, block insulation, spray fireproofing, thermal products
Owens-Illinois — Kaylo brand pipe covering, widely distributed through naval shipyards
Combustion Engineering — boiler components, gaskets, refractory materials
Babcock & Wilcox — boiler packing, refractory brick, thermal insulation
Armstrong Cork / Armstrong World Industries — pipe covering, block insulation, transite materials
W.R. Grace — Monokote spray fireproofing, block insulation
Owens Corning — Thermobestos and related thermal products
Crane Co. — valves, gaskets, thermal insulation components
Eagle-Picher — pipe insulation, block insulation, specialty asbestos products
Garlock Sealing Technologies — gaskets, packing materials, sealing compounds

Which Trades Carried the Highest Asbestos Exposure

Pipe Laggers and Insulators

Pipe laggers — heat and frost insulators — reportedly sustained the most direct and intense asbestos exposure at Charleston. Their work allegedly included:

Handling raw Kaylo pipe covering, Thermobestos block insulation, and related products
Mixing asbestos cements and adhesives containing chrysotile fibers
Applying thermal insulation to steam lines, fuel lines, and high-temperature piping throughout naval vessels
Stripping degraded insulation during overhaul and drydock work — the activity that allegedly released the highest airborne fiber concentrations
Working in enclosed, poorly ventilated shipboard spaces without respiratory protection for most of the yard’s operating history

Insulation removal during overhaul cycles reportedly generated airborne asbestos concentrations among the highest ever measured in industrial settings. Laggers working at Charleston are alleged to have accumulated cumulative exposures far exceeding any threshold later recognized as safe.

Boilermakers

Boilermakers worked in confined fire rooms and engine rooms. Their alleged exposures included:

Cutting, fitting, and removing boiler packing and gaskets containing asbestos
Working with Babcock & Wilcox refractory brick and thermal insulation inside boiler furnaces
Handling Crane Co. and Garlock Sealing Technologies gaskets on high-pressure steam systems
Breathing fibers disturbed by simultaneous insulation removal by pipe laggers working in the same spaces

Combustion Engineering, Babcock & Wilcox, and Johns-Manville products allegedly contaminated these confined spaces continuously throughout overhaul operations.

Pipefitters and Plumbers

Pipefitters and plumbers repeatedly cut through existing pipe insulation to access and repair system components. They are alleged to have:

Disturbed Kaylo pipe covering and Armstrong Cork products without respiratory protection
Encountered ACMs throughout their careers as Johns-Manville, Owens Corning, and related products were modified and repaired
Worked in spaces where settled asbestos dust from prior insulation work accumulated on surfaces and equipment

Electricians

Electricians at Charleston are alleged to have encountered asbestos across multiple product categories:

Asbestos-wrapped conduit in engine rooms and machinery spaces
Transite panels, Gold Bond asbestos-cement, and bulkhead covering supplied by Armstrong World Industries
Asbestos-insulated cable by Johns-Manville and Owens Corning in confined compartments
Asbestos-containing wallboard used in shipboard construction

Painters and Sandblasters

Painters and sandblasters reportedly worked on and adjacent to surfaces coated with Monokote and Zonolite spray fireproofing supplied by W.R. Grace. Sanding, scraping, and surface preparation allegedly disturbed asbestos fibers embedded in these coatings, generating inhalation exposure throughout overhaul and maintenance cycles.

Welders and Shipfitters

Welders and shipfitters working in confined hull spaces are alleged to have inhaled fibers disturbed by insulators, painters, and demolition trades working simultaneously in the same areas. This cross-trade contamination is well-documented in shipyard exposure literature and litigation records. Johns-Manville, W.R. Grace, and Owens-Illinois products were frequently being removed or applied in these shared spaces.

Carpenters and Laborers

Carpenters and laborers are alleged to have:

Handled transite board, Gold Bond asbestos-cement, and related products used in bulkheads and fire barriers
Worked with asbestos-containing deck tile and adhesives
Cleaned spaces contaminated with settled asbestos dust from insulation removal
Moved materials and equipment through contaminated work areas without protective gear

When Exposure Was Highest: Overhaul and Drydock Cycles

Overhaul and drydock work — not new construction — allegedly created peak airborne asbestos concentrations at Charleston and other naval facilities.

Why overhaul generated the most exposure:

Aged and degraded Kaylo, Thermobestos, and other insulation products were stripped by hand or with power tools, releasing respirable fibers in quantity
Work occurred in enclosed shipboard spaces with inadequate ventilation
Multiple trades worked simultaneously in confined areas, spreading fibers across shared spaces
Accumulated asbestos dust from prior work settled in bilges and equipment spaces, becoming re-entrained during disturbance
No abatement procedures existed for most of the yard’s operating life
Johns-Manville, Owens-Illinois, W.R. Grace, and Armstrong Cork are alleged to have supplied these products while possessing internal data on fiber release during removal

Peak exposure periods at Charleston:

Post-WWII overhaul cycle (1945–1960s): Fleet maintenance programs brought war-damaged vessels in for repair, requiring removal of Johns-Manville, Owens-Illinois, and Combustion Engineering insulation on a large scale
Cold War fleet maintenance (1960s–1980s): Continuous overhaul programs kept demolition-intensive repair work operating near constantly, with pipe laggers regularly stripping Kaylo and related products
Nuclear submarine refit (1970s–1990s): Nuclear-powered vessel maintenance required intensive removal and replacement of insulation systems supplied by Johns-Manville, Owens Corning, and W.R. Grace

Workers are alleged to have encountered airborne fiber concentrations far above thresholds OSHA would not establish until 1972 — by which time many Charleston workers had already accumulated decades of unprotected exposure.

What Federal Regulations Said About Shipyard Asbestos Exposure

OSHA Acted Decades After Industry Knew the Hazard

OSHA’s regulatory timeline shows that civilian shipyard workers at facilities like Charleston reportedly worked without enforceable exposure limits long after asbestos hazards were documented in medical literature:

1972: OSHA’s first permissible exposure limit (PEL) — 5 fibers per cubic centimeter (f/cc) — established for the first time, despite documented medical knowledge of asbestos disease dating to the 1930s
1976: PEL tightened to 2 f/cc
1986: PEL reduced again to 0.2 f/cc
1994: Final OSHA shipyard standard adopted specific to maritime industries, requiring medical surveillance, respirator programs, and regulated work areas

Workers at Charleston who handled Johns-Manville pipe covering in 1955, stripped Kaylo insulation during 1968 overhaul cycles, or removed W.R. Grace spray fireproofing in the 1970s did so without the respiratory protection, air monitoring, or exposure controls these later standards required.

EPA NESHAP regulations separately govern asbestos demolition and renovation at facilities like shipyards. Notification requirements apply when ACMs are disturbed in quantities above regulatory thresholds — records generated under these requirements may document ACM presence and condition at Charleston during later operational periods.

Legal Options for Charleston Naval Shipyard Workers: VA Claims and Civil Lawsuits

Federal Maritime Lawsuit Against Manufacturers

Civilian shipyard workers diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may file suit under federal maritime law against the manufacturers who supplied the products that allegedly caused their disease. These cases have recovered billions in settlements and verdicts across the country.

Filing deadline: 46 U.S.C. § 30106 sets a 3-year statute of limitations running from the date of diagnosis. Do not wait. Evidence degrades, witnesses become unavailable, and trust fund claim windows close. An attorney must evaluate your case immediately.

Federal maritime courts handling shipyard asbestos cases include the Eastern District of Virginia, the Southern District of Texas, and the Western District of Washington, among others.

What these lawsuits must establish:

The plaintiff worked at Charleston Naval Shipyard during periods when ACMs were present
The plaintiff’s work brought them into contact with products manufactured by identifiable defendants
The plaintiff’s diagnosed disease — mesothelioma, asbestosis, or lung cancer — is causally linked to that asbestos exposure
The defendant manufacturers knew or should have known of the hazard and failed to warn

Recent News & Developments

Charleston, South Carolina has maintained a visible presence in mesothelioma awareness efforts. In October 2020, the City of Charleston formally proclaimed Mesothelioma Awareness Day for the ninth consecutive year, an initiative organized in part through Motley Rice, a prominent asbestos litigation firm headquartered in the city. This annual recognition reflects the lasting public health legacy of decades of shipyard operations along the Cooper River, where workers at Charleston Naval Shipyard were routinely exposed to asbestos-containing insulation, pipe lagging, gaskets, and deck materials during ship overhaul and drydock operations.

On the environmental and regulatory front, the EPA’s ongoing review of Clean Water Act coverage and Superfund enforcement priorities continues to affect former industrial sites across South Carolina. While no active Superfund designation has been publicly announced specifically for the former Charleston Naval Shipyard property, veterans and community advocates continue to monitor remediation activities at the North Charleston site, which has undergone phased redevelopment since the shipyard’s closure under the 1993 Base Realignment and Closure process. Former workers and their families should be aware that environmental cleanup timelines at converted naval facilities can surface documentation relevant to occupational exposure histories.

For VA benefits purposes, shipyard veterans diagnosed with mesothelioma, asbestosis, or related asbestos-caused cancers should note that the VA continues to process claims under 38 CFR § 3.309 and associated asbestos policy guidelines, including M21-1 manual provisions governing military occupational asbestos exposure. Veterans who served aboard vessels overhauled at Charleston Naval Shipyard, or who worked in its drydock and repair facilities between roughly the 1940s and 1980s, may qualify for service-connected disability ratings. The Blue Water Navy Vietnam Veterans Act of 2019 remains in effect, expanding presumptive eligibility for certain veterans who served offshore, and legislative activity in Congress continues to address gaps in presumptive coverage for toxic exposures more broadly.

Regarding asbestos litigation, multiple manufacturers whose products were installed in U.S. Navy vessels — including pipe insulation, boiler block, and turbine covering manufacturers — have established bankruptcy trust funds that remain active for shipyard worker claims. Trust fund payment tiers and submission deadlines are subject to periodic trustee review, and claimants should consult with experienced asbestos attorneys to ensure timely filing.

Civilian and military workers at this shipyard who were diagnosed with mesothelioma, lung cancer, or asbestosis may have legal rights under federal maritime law and applicable state statutes. Multiple asbestos trust funds hold assets specifically for shipyard workers and their families.
