Maryland Asbestos Exposure Sites: Worksites, Industries, and Trust Coverage

Reviewed by Justinian C. Lane, Attorney Last reviewed November 2026

A small state by area, Maryland packed in more heavy work than its size suggests: for a time the largest steel plant in the world at Sparrows Point, a harbor full of shipyards and dry docks, coal-fired power stations along the Potomac and the Chesapeake, and an unusual share of the federal government's laboratories, arsenals, and naval stations. Almost all of it ran on steam and high heat, and asbestos was what kept that heat in the pipes, boilers, and furnaces. Most of the trusts' Maryland entries fall into five areas:

  • the Baltimore harbor — Bethlehem Steel's Sparrows Point plant and shipyard, its Key Highway repair yard, and Maryland Shipbuilding & Drydock at Curtis Bay;
  • industrial Baltimore — the Armco and Eastern Stainless steel mills and Johns Hopkins Hospital;
  • the Washington suburbs — NASA Goddard at Greenbelt, the National Bureau of Standards at Gaithersburg, and the National Institutes of Health at Bethesda;
  • the Potomac and the Patuxent — the Navy's powder works at Indian Head and Pepco's Morgantown and Chalk Point generating stations; and
  • Western Maryland — the Westvaco paper mill at Luke and the Celanese fiber plant outside Cumberland.

Aberdeen Proving Ground on the upper bay, Fort Meade between Baltimore and Washington, and the Naval Academy at Annapolis round out a long list of military posts.

When these companies went bankrupt, the trusts set up to pay their asbestos claims each published a list of locations where its products were proven to be present. For Maryland, those lists hold more than 2,000 entries across 181 communities, from 28 asbestos trusts. One plant can appear many times, under different names or on different trusts' lists. More than a dozen of our clients worked at Maryland job sites.

Every asbestos trust claim has to prove two things: that a company's asbestos-containing product was present at a job site, and that the worker handled that product, or worked close enough to it, to breathe its dust. If you or your loved one worked at a site on those lists during the applicable years, the first half is already established, because the trust has acknowledged its products were there.

We help workers who are alive and recently diagnosed, adult children and spouses researching on behalf of someone who is sick, and families of workers who have already passed away from mesothelioma, lung cancer, or asbestosis. If you are a worker who has just been diagnosed, calling early keeps more options open for your family. There is still a claim to be made for families of workers who have already passed; we handle wrongful death cases routinely.

You don't need the product names or old records. No fee unless we recover compensation for your family.

Maryland filing deadlines and trust eligibility, in brief

Maryland gives a diagnosed worker three years to file a personal-injury claim. Exactly when the clock starts varies, so to be safe, count from the date of diagnosis. An earlier diagnosis of asbestosis does not start the clock for a later mesothelioma in Maryland: the three years run from the cancer's own diagnosis. But other early findings and an earlier lawsuit can matter, so call us right away. A separate deadline applies once a worker has passed away. If your loved one is alive and diagnosed, calling early keeps more options open.

Maryland deadlines, the wrongful-death rule, and how they apply to your family

Most workers exposed before 1983 can also file against the Johns-Manville Settlement Trust independently of anything documented at a specific site. How trust eligibility works.

We help families of workers who have already passed away. Wrongful death claims are a substantial portion of the cases we file in Maryland.

The sites profiled below show confirmed asbestos products based on the asbestos trusts established for companies that did business there. Those trusts exist because Clarence Borel, a Gulf Coast insulator, chose to sue in 1969 — not for himself, but because he realized his coworkers would die the same way he was dying. His decision created the legal framework that produced the trust system you're about to scan.

Today the choice is yours. You can file trust claims based on the documented exposure at your loved one's worksite — paper claims, no courtroom. Or you can follow Clarence Borel and also sue the manufacturers and premises owners directly, which allows us to build a full exposure profile for every site your loved one worked at and recover from defendants the trust system doesn't reach. Read his story.

Asbestos trust coverage across Maryland

The Johns-Manville Settlement Trust is open to most workers exposed before 1983, regardless of which specific worksite the exposure occurred at. Johns-Manville supplied so much asbestos and so many asbestos products across so many American industries that the trust does not require site-specific documentation. For mesothelioma claims, even one day of asbestos exposure before December 31, 1982 (at work or through a family member's work clothes brought into the home) can qualify a worker for Johns-Manville Settlement Trust compensation.

For lung cancer, asbestosis, and other non-mesothelioma asbestos diseases, the threshold is 60 months of total asbestos exposure with at least 6 months occurring before December 31, 1982. The one-day-of-exposure threshold for mesothelioma reflects how the disease actually develops (even brief exposure can cause it) and most major asbestos trusts apply similarly low-threshold eligibility for mesothelioma claims.

Because Johns-Manville keeps no site list of its own, every worksite on another trust's list also qualifies for Johns-Manville. Twenty-seven other trusts list Maryland worksites. The number of Maryland entries on each trust's list:

Trust coverage at this depth means most Maryland workers with significant industrial exposure histories will trigger filings against multiple trusts simultaneously — typically Johns-Manville plus the site-specific trusts documented at their worksites.

Maryland cities and their industries

Open a city to see the worksites there that the asbestos trusts recognize, grouped by industry, with why each industry used asbestos.

BaltimoreBaltimore holds more than half of Maryland's entries: the harbor's shipyards and dry docks, the Armco and Eastern Stainless steel mills, BGE's generating stations, and Johns Hopkins Hospital.13 worksites

Shipyards. Ships' boilers, engine rooms, and steam lines were insulated with asbestos, much of it to Navy specification, and shipyard workers in tight spaces breathed the dust whether or not they handled it themselves.

  • Bethlehem Steel Key Highway Shipyard
  • Maryland Dry Dock
  • Maryland Shipbuilding & Drydock Company
  • U.S. Coast Guard Yard

Steel, metals, and metalworking. Steel mills, foundries, tool works, and aluminum plants used asbestos wherever metal was melted, poured, or heat-treated: refractory brick and cement, insulation on furnaces and ladles, and asbestos protective clothing.

  • Armco Steel
  • Bethlehem Steel (listed under Baltimore)
  • Eastern Stainless Steel

Paper mills and manufacturing plants. Paper mills, glass plants, lumber mills, and factories ran their own boilers and steam systems, insulated with asbestos pipe covering and sealed with asbestos gaskets. A paper mill's recovery boilers were among the most asbestos-intensive equipment anywhere.

  • General Refractories
  • Lever Brothers
  • Western Electric Point Breeze Works

Food plants, breweries, and sugar mills. Sugar mills, breweries, corn and flour mills, and packing houses ran on steam: boilers, cookers, evaporators, and dryers, with miles of insulated pipe, all built with asbestos insulation, gaskets, and packing.

  • Domino Sugars refinery (American Sugar Refining)

Public and commercial buildings. Office towers, hospitals, schools, hotels, and government buildings were built with asbestos fireproofing, insulation, plaster, and floor tile, exposing the trades who built and renovated them and the maintenance crews who kept their boilers and steam lines running.

  • Johns Hopkins Hospital

Power plants and utilities. Power plants' boilers, turbines, and high-pressure steam lines were insulated, lined, and sealed with asbestos products, and every overhaul released dust across the plant.

  • BGE Herbert A. Wagner Generating Station
CumberlandCumberland, in western Maryland, combined the Celanese acetate-fiber plant at Amcelle with the Kelly-Springfield tire plant, PPG's glass works, and the B&O and Western Maryland railroads.2 worksites

Paper mills and manufacturing plants. Paper mills, glass plants, lumber mills, and factories ran their own boilers and steam systems, insulated with asbestos pipe covering and sealed with asbestos gaskets. A paper mill's recovery boilers were among the most asbestos-intensive equipment anywhere.

  • PPG (Pittsburgh Plate Glass)

Textile and garment plants. Textile and garment plants ran steam for dryers, presses, and heating, and their boiler rooms and maintenance shops carried the same asbestos insulation, gaskets, and packing as any industrial plant.

  • Celanese plant (Amcelle)
Sparrows PointSparrows Point, on the Patapsco River southeast of Baltimore, was Bethlehem Steel's integrated steel plant and the shipyard beside it, which the trusts list separately.2 worksites

Mesothelioma settlement values at Maryland's most-documented worksites

These worksites appear on the approved-site lists of at least six trusts besides Johns-Manville. Trust counts are minimums: a trust may list a site under a name we haven't yet matched to it. The years are the exposure window the trusts' lists recognize at each site; most lists end at 1982.

Open a worksite to see each trust that lists it, with the mesothelioma values the trust publishes and its current payment percentage. "Trust values together" adds up those trusts' values at their payment percentages: the low figure uses each trust's scheduled value, the high figure each trust's published maximum, which Individual Review can reach. Most mesothelioma claims are paid above the scheduled value. But each trust sets its own eligibility rules — the years, the work, and the length of exposure it requires — so few people qualify for every trust on a list, some trusts publish no fixed schedule, and these figures are not a prediction of any recovery. All trust values and payment percentages.

A closer look at major Maryland worksites

The worksites below are recognized by the most asbestos trusts in Maryland — ten or more, counting Johns-Manville. Each profile draws on the trust signatures present at the site to identify the products workers handled, the trades most heavily exposed, and the asbestos types they likely encountered. Your specific worksite may be documented even if it doesn't appear here — call us.

Bethlehem Steel Sparrows Point plant — Sparrows Point

Recognized by at least 16 asbestos trusts · 1919–1982

Steelmaking at Sparrows Point, on the Patapsco River southeast of Baltimore, began in the late 1880s under the Maryland Steel Company. Bethlehem Steel bought the plant in 1916 and built it into the largest steel plant in the world by the late 1950s, when it employed more than 30,000 people. After Bethlehem's bankruptcy the plant passed through several owners and closed in 2012. The trusts list it under Bethlehem Steel, Maryland Steel, and Sparrows Point Steel Mill, and by department — the coke ovens, blast furnaces, open hearths, hot strip and tin mills, and the Penwood power station; it is one facility. The shipyard beside it is listed separately and profiled below.

Workers exposed. Integrated steel operations of this scale required millwrights, boilermakers, pipefitters, refractory workers (bricklayers), insulators, mechanics, electricians, riggers, crane operators, and a broad skilled trades workforce across coke ovens, blast furnaces, open hearths, and the rolling mills.

Trust documentation: recognized by at least 16 asbestos trusts — A.P. Green, Armstrong World Industries, Babcock & Wilcox, Combustion Engineering, DII Industries (Halliburton), DII Industries (Harbison-Walker), Eagle-Picher, Fibreboard, Kaiser Aluminum, Owens Corning, Owens-Illinois, Pittsburgh Corning, Plibrico, Raytech, U.S. Gypsum, and Johns-Manville. The trusts' lists document their products here from 1919 through 1982.

Products, trust signatures, and asbestos types. A.P. Green and Harbison-Walker refractory brick and cement, Plibrico plastic refractory, and Kaiser refractory products lined the coke ovens, blast furnaces, open hearths, soaking pits, and reheat furnaces. Babcock & Wilcox and Combustion Engineering boilers in the plant's boiler houses and at the Penwood power station carried pipe and block insulation and gaskets and packing on access doors and steam connections. Because the Owens-Illinois trust signature is present, Owens-Illinois Kaylo high-temperature pipe insulation, an amosite (brown asbestos) product, was used at this site during the 1948–1958 manufacturing window, with Owens Corning continuing the Kaylo line afterward; Pittsburgh Corning's amosite-rich Unibestos covered the hottest steam service, and Fibreboard pipe insulation, Eagle-Picher insulating cement, and Armstrong insulation covered more of the miles of steam and process piping. The Halliburton signature reflects pumps and compressors from Ingersoll, Dresser, Pacific, and Worthington, Raytech reflects friction products on the cranes and mill drives, and U.S. Gypsum reflects joint compound and plaster in the plant's offices and shop buildings. Chrysotile (white asbestos) ran through most of these product categories, and crocidolite (blue asbestos) appeared in the gaskets and packing of the plant's acid service.

Bethlehem Steel Sparrows Point Shipyard — Sparrows Point

Recognized by at least 12 asbestos trusts · 1926–1982

Bethlehem's shipbuilding division ran a shipyard on the Sparrows Point peninsula beside the steel plant, building tankers, freighters, and other merchant and naval hulls through much of the twentieth century. The trusts list it as the Sparrows Point Shipyard and the Bethlehem Steel Shipbuilding Division, and ACandS's list names more than a dozen individual hulls built there in the 1960s and early 1970s, among them the Santa Mariana, the Texaco Maryland, and the Overseas Alaska; it is one facility.

Workers exposed. Shipbuilding required boilermakers, pipefitters, insulators, sheet-metal workers, machinists, electricians, welders, riggers, and shipfitters working in close quarters in engine rooms, boiler rooms, and machinery spaces, where every trade breathed the dust of the insulators' work.

Don't see your worksite?

Your worksite may be documented even if it doesn't appear on this page. If your loved one worked at a Maryland facility not listed, call us. Johns-Manville requires no site list at all, and we can often document exposure through the products, contractors, and equipment at a site even when no trust lists it by name.

Smaller worksites, contract jobs, short-tenure employment, and exposures across multiple sites are all part of the case-building process.

How a Maryland case may work

Robert is a 76-year-old retired pipefitter who spent his career across Baltimore Harbor. From 1968 to 1979 he worked at Maryland Shipbuilding & Drydock at Curtis Bay, cutting and fitting pipe insulation and replacing gaskets and packing on shipboard valves and pumps during the construction and repair of merchant vessels and Navy ships. In 1979 he moved to Bethlehem Steel Sparrows Point, where he worked on the high-temperature steam piping running through the hot strip mill and the boiler houses for the next twenty-six years until retirement in 2005. His daily work involved removing and replacing pre-formed pipe insulation, mixing and applying insulating cement, replacing pump and valve packing, and handling refractory cement on the rolling mill equipment. In early 2026 Robert was diagnosed with pleural mesothelioma of the epithelioid mesothelioma subtype.

Robert's case profiles into two parallel tracks. On the trust side, the Sparrows Point plant listings alone support filings against at least fifteen site-specific trusts — A.P. Green, Armstrong World Industries, Babcock & Wilcox, Combustion Engineering, DII Industries (Halliburton), DII Industries (Harbison-Walker), Eagle-Picher, Fibreboard, Kaiser Aluminum, Owens Corning, Owens-Illinois, Pittsburgh Corning, Plibrico, Raytech, and U.S. Gypsum — and the Maryland Shipbuilding & Drydock listings confirm at least eight of the same trusts at a second site. Because Robert's career began in 1968 — well before December 31, 1982 — his exposure also qualifies him for the Johns-Manville Settlement Trust, in addition to the site-specific trust filings. On the federal-benefits side, his civilian shipyard work at Maryland Shipbuilding & Drydock is covered by LHWCA. On the civil side, his exposure to documented manufacturer products at both sites supports claims against the still-solvent manufacturers. Robert's wife and adult children are also eligible for our firm's free asbestos health screening, given the take-home exposure that comes with decades of insulation and gasket work brought home on work clothes. The screening is a chest X-ray read by a B-reader, with a CT scan if needed; it looks for asbestos-related changes in the lungs and isn't a diagnosis or a reliable way to find mesothelioma early. Recoveries from cases like Robert's routinely fund what insurance does not cover — travel to academic cancer centers, lodging during extended treatment, out-of-pocket medication costs, and home help. The nearest NCI-designated cancer center for a Maryland worker is the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins in Baltimore, where advanced treatments like lung-sparing surgery, HIPEC for peritoneal cases, and the latest immunotherapy combinations are available. When the written agreement and applicable law permit it, our firm can also advance the cost of travel and lodging when getting to the right treatment center is important. How legal recovery funds mesothelioma treatment access →.

For the full doctrinal treatment of Maryland's discovery rule, contributory negligence framework with the strict-liability carve-out, premises liability standard, and damages framework, see the Maryland mesothelioma law guide.

This example is general. Every case depends on the diagnosis, exposure history, dates, defendants, applicable law, and available evidence.

What happens when you call

A staff attorney answers — not a screener. The first call usually runs 20 to 30 minutes. We listen to the work history, identify which Maryland worksites and trust channels apply to your loved one's exposure, and explain the timeline and case structure for your family's specific situation.

We never pressure anyone to retain us during the first call. If you decide to move forward, we come to you — phone, video, or home visit, whichever works best. No travel to our offices is required at any point in the case.

You do not need to come to the call with product names, exposure dates, or work records. We reconstruct the exposure history using our worksite database, the trust documentation for each manufacturer, employment and union records, and coworker interviews. The conversation starts with what you remember; we handle the documentation work from there.

A spouse, adult child, or other family member can call for the worker. Many of our first calls are from a daughter or wife researching on behalf of a parent or husband. That is standard, and the family member can make the call without the worker on the line.

Frequently asked questions

Is my Maryland worksite documented?

Probably yes. The asbestos trusts' approved-site lists hold more than 2,000 Maryland entries in 181 communities — steel mills, shipyards, hospitals, power plants, paper and fiber mills, federal laboratories and military installations, and a wide range of smaller industrial and commercial operations across the state. You can search every entry on this page. Even if a specific facility isn't listed, we can often document exposure there through the products and contractors involved. Call us with the worksite name and we can confirm coverage during the first conversation.

What does "trust coverage" mean for my case?

Asbestos bankruptcy trusts were established when major asbestos manufacturers went bankrupt — they set aside money to pay future claimants. "Trust coverage" at a worksite means that one or more of those trusts has historically paid claims for exposure at that location, which simplifies the documentation we need to file your loved one's claim. Trust claims are paper claims — no courtroom, no deposition, no travel. Most resolve in 3–9 months.

Does my loved one qualify for the Johns-Manville trust?

Probably yes, if your loved one had asbestos exposure before 1983 and developed an asbestos-related disease. Johns-Manville does not require proof that its products were at a specific worksite, and for mesothelioma even one day of exposure can qualify. How Johns-Manville eligibility works.

Do I need to know which asbestos products my loved one handled?

No. You do not need to come to the call with product names or technical details. The trusts' site lists and our trust documentation files reconstruct the product universe at most documented worksites. We work from the worksite, the trade, the years worked, and the work performed — then we identify the products. Bring whatever you remember; we handle the rest.

What if my loved one worked at multiple Maryland sites?

That is common and often expands the case. A career that touched Bethlehem Steel Sparrows Point, Maryland Shipbuilding & Drydock, and the Key Highway Yard typically supports trust filings against many more trusts than any single site alone. We map the full career and file across every applicable trust.

What if my loved one's worksite has closed or been demolished?

Bethlehem Steel Sparrows Point closed in 2012. Many of Maryland's other industrial facilities have closed or been demolished. Closure has no effect on the case. Trust claims are based on documented historical product use, not on the facility still being open. Civil claims are based on the manufacturers' historical sales into the facility, not on the facility's current status. Closed and demolished facilities make up a substantial share of the cases we file.

Can we file a claim if my loved one already passed away?

Yes. If the asbestos disease came from the worker's job, Maryland requires the family's wrongful-death claim to be filed within three years of when the family knew or reasonably should have known the cause of death (usually three years from the death, when the diagnosis came during life), and never more than ten years after the death; for other deaths it is three years from the death. The estate's claim for the worker's own losses keeps the worker's own deadline. Trust claims are also available to the estate. We handle wrongful death cases routinely in Maryland.

My loved one was a civilian employee at a Maryland federal facility — does that change the case?

It expands the case. Federal civilian employees at facilities like NASA Goddard, Aberdeen Proving Ground, Fort Meade, the U.S. Naval Academy, Indian Head, Patuxent River, Walter Reed/NSA Bethesda, NIH, Fort Detrick, and the SSA headquarters are covered by FECA. Civilian workers at the U.S. Coast Guard Yard at Curtis Bay are federal employees too, covered by FECA; workers at private shipyards are covered by LHWCA. Military veterans may be eligible for VA service-connected disability. These federal benefits run in parallel with trust claims and civil claims; some must be coordinated, because a few programs carry offsets or repayment rules.
