Asbestos Exposure at Dow Chemical – Marietta


⚠️ OHIO FILING DEADLINE WARNING: YOUR TIME IS LIMITED

Ohio law imposes a strict two-year statute of limitations under Ohio Rev. Code § 2305.10. If you or a family member has been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer, you have two years from the date of diagnosis — not from the date of exposure — to file a civil lawsuit. Once that two-year window closes, it closes permanently. No Ohio court can extend it.

Asbestos bankruptcy trust fund claims — available against companies like Johns-Manville, Owens-Illinois, Eagle-Picher, W.R. Grace, and Armstrong World Industries — can be filed simultaneously with a civil lawsuit in Ohio. Most trusts do not impose strict filing deadlines, but their assets are finite and actively depleting. Workers and families who delay filing trust claims risk receiving lower compensation as fund assets shrink.

Every month of delay costs you. Call a mesothelioma lawyer in Ohio today.


Chemical Plant Workers and Their Families Faced Real Health Risks

If you worked at the Dow Chemical facility in Marietta, Ohio during the 1940s–1980s, or if a family member did, you may have been exposed to asbestos-containing materials that cause mesothelioma, asbestosis, and lung cancer. These diseases typically do not appear until 20–50 years after exposure. Many workers who believed they were safe are now receiving diagnoses.

Manufacturers including Johns-Manville, Owens-Illinois, Armstrong World Industries, W.R. Grace, and Eagle-Picher produced asbestos-containing products reportedly used at this facility. These companies are alleged to have known about the health dangers and failed to warn workers. You may have legal rights to asbestos compensation under Ohio law — but Ohio’s two-year filing deadline means you cannot afford to wait. An asbestos attorney in Ohio can protect those rights.


Asbestos Exposure at the Marietta Plant: Why This Facility Was a High-Risk Workplace

How the Marietta Chemical Plant Operated

Dow Chemical established its Marietta, Ohio operations along the Ohio River in Washington County, positioned for access to water resources, transportation infrastructure, and the raw materials required for chemical manufacturing. The Marietta facility became one of Dow’s major production sites in the eastern United States and remains one of the most significant industrial employers in the Ohio River Valley region. The facility reportedly produced:

  • Chlorine
  • Caustic soda
  • Industrial and specialty chemicals
  • Processing chemicals for downstream manufacturing

Washington County and the surrounding Ohio River Valley corridor have historically housed some of Ohio’s most intensive industrial operations — facilities that, like Dow Marietta, reportedly made extensive use of asbestos-containing materials throughout the mid-twentieth century.

When Asbestos-Containing Materials Were Standard in Ohio Chemical Plants

The plant was constructed and substantially expanded during the 1940s through the 1980s — the same period when asbestos-containing materials dominated thermal insulation, fire protection, and equipment maintenance across American heavy industry, including at major Ohio industrial sites such as Cleveland-Cliffs Steel, Republic Steel in Youngstown, Goodyear in Akron, and B.F. Goodrich in Akron.

During these decades, the Marietta facility reportedly underwent multiple construction and renovation phases, each allegedly involving:

  • Installation of asbestos-containing insulation, including products such as Johns-Manville block insulation and Unibestos pipe covering
  • Maintenance and removal of deteriorating asbestos-containing materials
  • Disturbance of asbestos-containing products during equipment repairs

Maintenance operations performed daily by trades workers — including members of Boilermakers Local 900, Asbestos Workers Local 3 (Cleveland), and other Ohio-based union locals — may have continuously disturbed these materials, releasing respirable asbestos fibers into workers’ breathing zones.


Why Chemical Plants Used Asbestos: Products and Hazards

Chemical plants ran at temperatures and pressures that required asbestos-containing materials for decades. The scope of alleged asbestos exposure at the Marietta facility follows directly from how these plants operated — and mirrors documented conditions at other major Ohio industrial facilities during the same era.

Thermal Insulation for Extreme-Temperature Equipment

Piping, reactors, boilers, and processing equipment at chemical plants routinely operated above 1,000°F. Asbestos-containing materials were the industry standard for managing this heat across Ohio and throughout the United States:

  • Asbestos-containing pipe covering wrapped around steam lines and hot chemical lines — products such as those manufactured by Johns-Manville and Eagle-Picher
  • Block insulation for vessels and equipment — including Armstrong World Industries asbestos-containing block insulation and Kaylo products
  • Blanket insulation for pipes and ducts — products manufactured by Owens-Illinois and Owens Corning
  • Calcium silicate insulation with asbestos binder — including Thermobestos products

These same product lines appear in litigation records from other major Ohio facilities, including Republic Steel in Youngstown and Goodyear’s Akron plants.

Gaskets and Packing Materials

High-pressure connections between pipes, valves, pumps, and reactors required asbestos-containing gaskets and valve packing that could withstand heat, pressure, and chemical corrosion. When workers cut, installed, or removed these materials — manufactured by Garlock Sealing Technologies and Crane Co. — they allegedly released asbestos fibers into the air at the worksite. Garlock and Crane Co. products are among the most frequently identified asbestos-containing materials in Ohio industrial facility litigation records.

Boilers and Steam Systems

Steam generation was central to chemical manufacturing. Boilers and associated systems were typically insulated with:

  • Asbestos-containing boiler block insulation from Johns-Manville and Armstrong World Industries
  • Asbestos-containing pipe covering from Eagle-Picher and Unibestos
  • Asbestos-containing refractory cements and Cranite products

Boiler repair and maintenance work carried some of the highest asbestos exposure levels documented in industrial hygiene literature. This pattern of exposure is well established in Ohio mesothelioma litigation involving boilermakers at facilities throughout the state.

Fireproofing and Building Materials

Structural elements throughout the facility may have contained asbestos-containing materials:

  • Spray-applied asbestos-containing fireproofing on structural steel — including Monokote products from W.R. Grace
  • Asbestos-containing floor tiles marketed as Gold Bond products
  • Asbestos-containing ceiling tiles and acoustical materials
  • Asbestos-containing roofing materials from Celotex and Georgia-Pacific

Products Allegedly Present at Dow Marietta: Asbestos-Containing Materials

Based on operations conducted at the Marietta facility and documented practices at large chemical plants of this era, the following asbestos-containing products may have been present at this location:

Insulation Products:

  • Owens-Illinois and Owens Corning asbestos-containing pipe insulation
  • Johns-Manville asbestos-containing pipe covering and block insulation
  • Armstrong World Industries asbestos-containing block insulation
  • Eagle-Picher asbestos-containing pipe covering
  • Unibestos asbestos-containing pipe covering
  • Kaylo asbestos-containing thermal insulation
  • Thermobestos asbestos-containing calcium silicate insulation

Gaskets, Seals, and Packing:

  • Garlock Sealing Technologies asbestos-containing gaskets
  • Crane Co. asbestos-containing valve packing
  • Combustion Engineering asbestos-containing gasket materials

Fireproofing and Coatings:

  • W.R. Grace Monokote asbestos-containing fireproofing
  • Aircell asbestos-containing spray-applied fireproofing
  • Asbestos-containing refractory cements and coatings used in high-temperature applications

Building Materials:

  • Gold Bond asbestos-containing floor and ceiling tiles
  • Georgia-Pacific asbestos-containing roofing materials
  • Celotex asbestos-containing insulation and building products
  • Pabco asbestos-containing roofing and siding materials

An experienced asbestos attorney in Ohio can verify specific product presence through deposition records, product identification databases, NESHAP abatement records applicable to this site, and EPA ECHO enforcement data. Discovery is the proper vehicle for establishing specific product documentation.


High-Risk Occupational Groups: Who Has the Highest Asbestos Cancer Risk?

Multiple trades worked at the Dow Chemical Marietta facility across its operational history. Workers in the following categories may have been exposed to asbestos-containing materials during their time at this plant. If you worked in any of these roles, consult with an asbestos attorney in Ohio immediately.

Heat and Frost Insulators — Highest Exposure Risk

Insulators faced the highest documented asbestos exposure levels at facilities like Dow Marietta. Their core job — installing and removing thermal insulation from pipes, boilers, vessels, and equipment — placed them in direct, daily contact with asbestos-containing materials.

Their alleged exposure sources included:

  • Handling asbestos-containing pipe covering and block insulation from Johns-Manville, Armstrong World Industries, and Eagle-Picher
  • Mixing asbestos-containing cements and coatings
  • Cutting and shaping asbestos-containing materials including Kaylo and Unibestos products
  • Generating heavy concentrations of airborne asbestos dust

Workers represented by Asbestos Workers Local 3 (Cleveland) and affiliated Ohio locals who worked at large chemical plants during this era appear among the most frequently identified mesothelioma claimants in Ohio asbestos litigation. Insulator union records have proven valuable in establishing work histories in Cuyahoga County Common Pleas Court and other Ohio venues.

If you worked as an insulator at Dow Marietta and have received a mesothelioma or asbestos-related diagnosis, Ohio’s two-year filing deadline under Ohio Rev. Code § 2305.10 is already running. Consult a mesothelioma lawyer in Ohio today.

Pipefitters and Plumbers — Bystander and Direct Exposure

Pipefitters and members of Ohio-based pipefitter union locals installed, maintained, and repaired the extensive pipe networks carrying chemicals, steam, water, and other materials throughout the plant. This work may have required them to:

  • Work directly alongside asbestos-containing pipe insulation
  • Cut away insulation during pipe repairs
  • Disturb asbestos-containing materials while performing nearby maintenance
  • Work beside insulators actively handling asbestos-containing materials

Pipefitter union members who worked at Ohio chemical and industrial plants during this era — including at Ford’s Lorain Assembly plant and B.F. Goodrich facilities in Akron — report frequent, heavy contact with asbestos-containing insulation debris. Similar asbestos exposure patterns are alleged at the Dow Marietta facility.

Boilermakers — Highest Occupational Asbestos Risk

Boilermakers maintained, repaired, and installed boilers, pressure vessels, and heat exchangers central to chemical manufacturing. Their work may have placed them in direct contact with:

  • Asbestos-containing boiler insulation from Johns-Manville and Armstrong World Industries
  • Asbestos-containing refractory materials and Cranite products
  • Asbestos-containing gaskets manufactured by Garlock Sealing Technologies

Boilermaker work often required chipping and removing hardened asbestos-containing block insulation and cement from boiler surfaces — work that may have generated some of the heaviest airborne asbestos fiber concentrations recorded in industrial settings. Members of Boilermakers Local 900, which represents workers across Ohio industrial facilities, have been among the most frequently diagnosed with asbestos-related disease in Ohio workers’ compensation and civil litigation records.

If you are a boilermaker diagnosed with mesothelioma or asbestosis, contact an asbestos lawyer in Ohio about Ohio’s strict two-year filing window under Ohio Rev. Code § 2305.10. That clock starts on your diagnosis date — not when you stopped working.

Electricians and Other Trades

Electricians, maintenance mechanics, and millwrights may have been exposed through:

  • Working in the same spaces as insulators, pipefitters, and boilermakers who were actively disturbing asbestos-containing materials
  • Removing asbestos-containing electrical panel components and switchgear insulation
  • Disturbing asbestos-containing building materials during conduit and wiring installation
  • Performing maintenance work in bo
