Asbestos Exposure in Louisiana - Lung Cancer and Mesothelioma

The City of Natchitoches operates a municipally owned electric utility that serves customers within Natchitoches, Louisiana by acquiring wholesale power, operating city-owned substations and distribution lines, and handling metering, maintenance, and outage response; historically, many municipal systems also maintained small local generation or peaking units for reliability. At facilities like the City of Natchitoches, Natchitoches Municipal Power in Natchitoches, LA, work commonly involves substation operations, line construction and repair, and upkeep of transformers, switchgear, and, where present, generation equipment. As with many power industry sites built or operated during the mid-20th century, there was potential for asbestos exposure, particularly before the 1980s, from materials such as pipe and boiler insulation, turbine and generator insulation, refractory cement, gaskets and packing, and certain electrical components and building materials; workers most at risk would have included maintenance personnel, mechanics, pipefitters, electricians, and operators performing repairs or overhauls. Modern controls, phase-outs of asbestos-containing materials, and retrofit programs have reduced these risks, but legacy materials can still be encountered during renovation or demolition activities.

The City of Opelousas in Opelousas, Louisiana is the municipal government for the parish seat of St. Landry Parish, overseeing essential public services including water and wastewater treatment, street and drainage maintenance, sanitation, parks and recreation, police and fire protection, and administrative functions such as permitting and code enforcement. Much of a city's core infrastructure and public buildings can date to periods before modern building and safety standards, and in Opelousas, LA potential asbestos exposure could have occurred where older materials were present - such as insulation on boilers and steam or hot-water piping in plants and municipal buildings, asbestos-cement (transite) water or sewer lines, roofing and floor tiles, and friction products handled in fleet or public works garages. Tasks like pipe cutting or replacement, facility maintenance, and building renovation or demolition would have posed the greatest risk of fiber release, primarily affecting public works, utilities, and maintenance employees and outside contractors if proper controls were not in place.

The City of Opelousas Power Plant in Opelousas, Louisiana is referenced as a municipal utility site associated with local electricity generation and distribution for the City of Opelousas; while specific operational details are limited, facilities of this type typically operated steam boilers, turbines, and/or diesel generator sets connected to the local grid, supported by piping networks, fuel handling, switchgear, and maintenance shops. Prior to tighter regulations, asbestos-containing insulation, gaskets, packing, and fireproofing were commonly used on boilers, turbines, pipes, and some electrical components in power plants, meaning workers and contractors at this Opelousas, LA site - such as boiler operators, pipefitters, electricians, and maintenance personnel - could have faced potential asbestos exposure, particularly during repairs, overhauls, or demolition activities before the 1980s.

The City of Ruston - Ruston Power Plant in Ruston, Louisiana is associated with the municipality's electric utility and is understood to have supported local power needs, consistent with the historic practice of many Louisiana cities operating small generating stations for community distribution; such facilities typically used steam boilers, turbines or diesel engines, fuel systems, and extensive piping and switchgear, with some units later relegated to peaking/backup service or retirement as cities sourced bulk power from regional providers. As with many U.S. power plants built or operated before the 1980s, equipment and materials such as pipe and boiler insulation, gaskets, packing, cement, and certain electrical components commonly contained asbestos, creating potential exposure risks for workers and contractors during installation, maintenance, or renovation; modern abatement and safety practices mitigate these risks. Specific, site - unique operational details publicly available for the Ruston, LA location are limited.

The City of Ruston Water Works in Ruston, Louisiana is the municipal utility responsible for producing and delivering potable water, operating treatment and pumping facilities, maintaining storage tanks, water mains, service lines, meters, and hydrants, responding to leaks and main breaks, and ensuring water quality and regulatory compliance for residents and businesses. Typical operations include treatment and disinfection, system monitoring, routine maintenance, emergency repairs, and capital improvements to distribution infrastructure throughout Ruston, LA. As with many U.S. water systems built or expanded before the 1980s, the utility's older infrastructure may have included asbestos-containing materials such as asbestos-cement (transite) pipe, gaskets, valve packing, and thermal insulation on pumps or piping; tasks like cutting, tapping, drilling, or removing aged asbestos-cement pipe, or disturbing deteriorated insulation during repairs, could generate airborne asbestos dust and pose exposure risks to water department employees, pipefitters, plumbers, and contractors. Intact, buried asbestos-cement pipe does not typically present an airborne hazard to the public, but maintenance on legacy components historically required controls such as wet methods and respiratory protection. Accordingly, personnel who worked on older water distribution assets for the City of Ruston Water Works in Ruston, Louisiana may have faced potential occupational asbestos exposure depending on the age and composition of materials encountered.

The City Service Oil Co facility in West Lake Charles, LA refers to the large Gulf Coast petroleum refining complex originally developed by Cities Service in the 1940s and later operated as part of CITGO's Lake Charles operations in West Lake Charles, Louisiana. The site's operations have focused on processing domestic and imported crude oil into transportation fuels such as gasoline, diesel, and jet fuel, as well as petrochemical feedstocks, with distribution supported by the Calcasieu Ship Channel, pipelines, rail, and truck. Over decades of continuous operation, the refinery expanded and modernized, employing a substantial industrial workforce and numerous contractors for maintenance and turnarounds. Like many refineries built and operated during the mid - 20th century, City Service Oil Co in West Lake Charles, LA likely utilized asbestos - containing materials for high - temperature insulation on pipes, boilers, furnaces, and turbines, as well as asbestos gaskets and packing in pumps and valves, creating potential exposure risks - especially for pipefitters, insulators, boilermakers, maintenance mechanics, and other hands - on crafts prior to the widespread phase - out and abatement efforts of the 1980s. Potential exposure could also have occurred during repairs, lagging removal, equipment overhauls, and other activities that disturbed aging insulation or components. While later safety standards and abatement programs reduced these risks, the site remains one where historical occupational asbestos exposure may have occurred.

The City Service Oil Co. facility in West Lake Charles, Louisiana was a major Gulf Coast petroleum refining operation developed by Cities Service (later associated with the CITGO brand), situated along the Calcasieu Ship Channel to process domestic and imported crude with units typical of large refineries, including crude and vacuum distillation, catalytic conversion, hydrotreating, reforming, coking, sulfur recovery, and extensive storage and marine, rail, and pipeline logistics serving the Lake Charles industrial corridor. Built and expanded through the mid-20th century and ultimately integrated into what became the CITGO Lake Charles Manufacturing Complex in the Lake Charles area, the site supported round-the-clock operations and large maintenance and turnaround workforces. Like most refineries of its era, the West Lake Charles, LA complex historically used asbestos-containing insulation, refractory, gaskets, packing, and fireproofing on boilers, piping, turbines, heat exchangers, and other high-temperature equipment, creating potential asbestos exposure risks for operators, pipefitters, insulators, boilermakers, millwrights, electricians, laborers, and contractors - especially during maintenance, repairs, and demolition - until tighter controls and abatement programs were instituted in the late 1970s and 1980s.

City Services Oil Company (historically known as Cities Service and later associated with CITGO) operated a large petroleum refining complex in West Lake Charles, Louisiana, within the Lake Charles industrial corridor along the Calcasieu Ship Channel, where crude oil was processed into gasoline, diesel, jet fuel, lubricants, and petrochemical feedstocks using units such as cracking, reforming, hydrotreating, and related high-temperature operations. Established in the mid-20th century, the site became a major regional employer and fuel supplier for Lake Charles, LA, and the Gulf Coast. Like many refineries built and maintained before modern regulations, this facility likely incorporated asbestos-containing materials - insulation for pipes and boilers, gaskets and packing for pumps and valves, refractory linings in furnaces and FCC units, and protective products - creating potential asbestos exposure for refinery workers, pipefitters, insulators, boilermakers, maintenance crews, and contractors, especially during turnarounds, repairs, and equipment overhauls prior to the late 1970s; although controls improved over time, legacy materials could still pose risks when disturbed during renovation or demolition.

The City Services Refinery in Lake Charles, Louisiana - originally developed by the Cities Service Oil Company in the mid-1940s and later operated as the CITGO Lake Charles Manufacturing Complex - is a large, integrated petroleum refinery that processes a range of crude oils into transportation fuels and petrochemical feedstocks, including gasoline, diesel, jet fuel, and materials used for chemicals production; typical units at this site have included crude distillation, catalytic cracking, reforming, hydrotreating, alkylation, and coking, supported by extensive storage and logistics to move products in and out of Lake Charles, LA. Given its age and the industry's historical practices, asbestos-containing materials were widely used during much of the refinery's early and mid-20th-century operation for high-temperature insulation, gaskets, packing, and refractory linings in boilers, furnaces, piping, and other equipment, meaning employees and contractors - especially insulators, pipefitters, maintenance personnel, and turnaround crews - may have faced asbestos exposure before stricter controls and abatement programs were implemented from the late 1970s into the 1980s.

The City Water Department in Baton Rouge, Louisiana is identified as a water-utility worksite associated with municipal distribution system functions such as installing and maintaining water mains and service lines, operating pump stations and storage, and performing field services including leak repairs, valve replacements, and meter work. Public works and water department facilities of this type historically incorporated materials and equipment common to the era, and maintenance often involved excavation, pipe cutting, and equipment overhauls. Possible asbestos exposure at this Baton Rouge, LA location could have arisen from asbestos-containing components widely used in water systems, including asbestos-cement (AC) pipe, pipe gaskets and packing, valve and pump insulation, boiler and equipment lagging, and certain sealants; tasks like cutting or tapping AC pipe, grinding gaskets, or disturbing old insulation can release asbestos fibers. While detailed site-specific records are limited, the location is commonly cited among places where utility workers, plumbers, pipefitters, and contractors performing repairs or renovations may have encountered asbestos.

The City Water Department in Monroe, Louisiana is responsible for operating and maintaining the municipal drinking water treatment and distribution system, including treatment facilities, water mains and service lines, meters, leak response, water quality testing, and regulatory compliance for customers throughout Monroe, LA. As with many mid-20th-century municipal utilities, components historically used in water systems could include asbestos-containing materials such as asbestos - cement (transite) pipe, pipe gaskets, valve packing, and thermal insulation on equipment; work activities like cutting or tapping asbestos - cement pipe, replacing gaskets and packing, or disturbing older insulation could have created potential asbestos exposure risks for workers and contractors, particularly prior to modern safety controls. No site-specific confirmation of asbestos use or documented exposures unique to the City Water Department - Monroe, LA was located, but the general exposure pathways described above are recognized for similar water department operations from that era.

The Civic Center Building on Gravier St. in New Orleans, Louisiana is referenced as a potential asbestos exposure site, but specific operational or historical details about this property are not documented in available summaries. There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The Claiborne Gas Company - Lisbon Gas Processing Plant in Lisbon, Louisiana was an industrial facility associated with processing natural gas from regional fields, performing standard operations typical of gas plants such as inlet separation, gas treating (removal of contaminants), dehydration, compression, and recovery of natural gas liquids, supported by networks of compressors, heaters, heat exchangers, piping, and storage systems; while detailed public records on the plant's specific history are limited, the Lisbon, LA site has been listed among locations where asbestos exposure may have occurred, consistent with industry-wide use of asbestos-containing insulation on high-temperature equipment and piping, as well as asbestos gaskets and packing in valves and pumps prior to regulatory changes in the late 1970s, with maintenance and insulation work posing the highest potential exposure risks.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred. This note concerns the Clarion Hotel - New Orleans, LA in New Orleans, Louisiana.

The Claud Jones (Uss) - New Orleans, LA entry refers to USS Claud Jones (DE-1033), the lead ship of a Cold War destroyer escort class built by Avondale Shipyards in the New Orleans, LA area; designed for anti-submarine warfare, she carried out escort, patrol, and training missions typical of U.S. Navy ASW operations and underwent routine shipyard availabilities over her career. Because Navy vessels of this era incorporated extensive asbestos, potential exposure could have occurred for sailors - especially those in machinery spaces such as engine and boiler rooms, pump rooms, and auxiliary spaces - through pipe and block insulation, boiler and turbine lagging, gaskets, packing, valves, pumps, adhesives, and deck materials; likewise, Avondale and other shipyard workers in New Orleans, Louisiana faced similar risks during construction, fitting-out, repairs, and removal activities that generated asbestos-containing dust.

There is no additional information available on the Cleco - Baldwin, LA site, but it is on the list of sites where asbestos exposure may have occurred.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Cleco Power, LLC is a regulated Louisiana electric utility that generates, transmits, and distributes electricity across central and southern Louisiana; in Baldwin, Louisiana (St. Mary Parish), the company has operated facilities that support local electric service, such as a service center, substation, and related infrastructure for residential, commercial, and industrial customers. Utility sites developed or upgraded before the 1980s often incorporated asbestos-containing materials in insulation, gaskets, packing, and refractory linings on boilers, turbines, and steam or hot-water piping, as well as in some building materials and older electrical components. Because of this, employees and contractors performing maintenance, repairs, or equipment changeouts at Cleco Power, LLC in Baldwin, LA - particularly pipefitters, mechanics, insulators, boiler operators, and electricians - could have experienced asbestos exposure during earlier decades. Today, operations are subject to state and federal safety rules and asbestos abatement practices, which reduce ongoing exposure risk but do not eliminate potential legacy exposures from past work.

Cleco Power, LLC operates a long-standing electric generation complex in Lena, Louisiana that serves as one of the utility's principal production sites, commonly associated with the Rodemacher/Brame Energy Center and tied into Cleco's transmission network to supply customers across the state; operations at the Lena, LA facility have historically included fossil-fueled steam and gas-turbine units (with associated fuel handling, water treatment, emissions-control systems, and high - voltage substations) and ongoing maintenance and modernization work typical of large power stations. As with many U.S. power plants developed and expanded in the mid-late 20th century, equipment at this site historically could have incorporated asbestos-containing materials such as thermal pipe and boiler insulation, gaskets, packing, cement products, and electrical component insulation; maintenance, repair, and outage activities before comprehensive abatement programs posed potential exposure risks for trades including operators, pipefitters, insulators, electricians, millwrights, and contractors, with later controls implemented under OSHA/EPA regulations to manage any remaining materials.

Cleco Power, LLC's Mansfield, Louisiana location is associated with the Dolet Hills Power Station in DeSoto Parish, a lignite-fueled generating facility that supplied baseload electricity to the regional grid for decades after entering service in the mid-1980s and was permanently retired in 2021, with subsequent decommissioning and environmental compliance activities continuing at the site. The plant's operations included large boilers, a steam turbine-generator, fuel and ash handling, cooling water systems, and emissions control equipment, historically supported by lignite mined nearby. As with many U.S. power plants constructed or equipped during the twentieth century, materials containing asbestos were commonly used for thermal insulation, pipe lagging, gaskets, valve packing, boiler and turbine insulation, and certain electrical components; accordingly, workers and contractors performing installation, maintenance, repair, or abatement at Cleco Power, LLC's Mansfield, LA operations - especially before modern controls and substitution practices became standard - could have faced potential asbestos exposure, with risks reduced over time through regulation, abatement programs, and updated materials and procedures.

Clinton Engineering Works in Sterlington, Louisiana is on lists of locations where asbestos exposure may have occurred, but specific information about the facility's operations, timeframe, or ownership in Sterlington, LA is not publicly available. There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

For Coastwise Petroleum in Goodhope, Louisiana, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The Houma, Louisiana branch of Coburn Supply Co. operates as a wholesale distributor serving residential, commercial, and light industrial contractors with plumbing, HVAC, pipe-valve-fittings, waterworks, and related electrical and building products, typically offering counter sales, local delivery, and access to Coburn's regional inventory and kitchen/bath showroom lines; the company is a long-established, family-owned distributor founded in 1934 and headquartered in Beaumont, Texas, with multiple locations across the Gulf South including Louisiana. At Coburn Supply Co. - Houma, LA, possible asbestos exposure would most plausibly relate to historical industry practices: many plumbing, HVAC, and PVF products in earlier decades (such as certain pipe insulation, gaskets, packing, furnace or pipe cement, and transite pipe or flue materials) sometimes contained asbestos, and exposure could occur when handling, cutting, or cleaning dust from such materials, particularly before the 1980s when regulations curtailed asbestos use; however, there is no specific public documentation confirming asbestos-containing products were stocked or handled at this particular Houma location, so any potential exposure would be consistent with general supply-house conditions of that era rather than a site-specific finding.

Coca Cola - Shreveport, LA is understood to have been a Coca-Cola bottling and distribution site in Shreveport, Louisiana, supporting beverage production, packaging, warehousing, equipment maintenance, and regional deliveries to retailers. As with many industrial facilities operating before the 1980s, materials and equipment commonly used in such plants sometimes contained asbestos, including thermal insulation on boilers and steam piping, gaskets and packing in pumps and valves, insulation around bottle-washing equipment, roofing and siding products, and certain floor tiles; potential exposure would have been most likely for maintenance crews, mechanics, and contractors performing repairs, insulation work, or renovations where dust could be generated.

There is no additional information available on the Coca Cola Project - Shreveport, LA site, but it is on the list of sites where asbestos exposure may have occurred.

The Colonial Sugar facility in Gramercy, Louisiana was a major cane sugar refinery complex on the Mississippi River, originally developed in the early 1900s by Colonial Sugar and operated for decades to process raw cane into refined granulated sugar, syrups, and molasses using large boilers, clarifiers, evaporators, crystallizers, centrifuges, and packaging lines; over time the site changed hands and branding, including periods under the Colonial Sugars and later Imperial Sugar names, with portions modernized or repurposed for continued refining activity. Typical operations included receiving raw sugar by barge and rail, storing it in sheds, then refining through clarification and filtration, multi - stage evaporation and crystallization, drying, and bagging or bulk loading for distribution. As with many industrial plants of its era, possible asbestos exposure at Colonial Sugar - Gramercy, LA could have arisen from asbestos-containing insulation on boilers, steam piping, evaporators, and turbines, as well as from gaskets, valve packing, and certain building materials used prior to the 1980s; maintenance, repair, and demolition work posed the greatest risk of disturbing these materials and creating airborne fibers, potentially affecting pipefitters, insulators, boilermakers, millwrights, electricians, and other refinery workers at the Gramercy, Louisiana site.

Colonial Sugars Company operated a large cane sugar refinery in Gramercy, Louisiana, on the Mississippi River, where it processed raw sugar into refined granulated, powdered, and liquid sugars, with supporting operations that included a boiler/power house, multiple-effect evaporators and crystallizers, packaging lines, storage silos, and barge/rail shipping facilities; the plant was a major employer in St. James Parish and, after decades under the Colonial Sugars name, later became part of Savannah Foods & Industries and then Imperial Sugar Company, which saw the site heavily damaged by a combustible dust explosion in 1999 before portions were rebuilt and modernized. As with many early- to mid-20th-century industrial facilities, asbestos-containing materials were commonly used for thermal insulation and fireproofing in equipment such as boilers, steam and condensate lines, evaporators, turbines, pumps, and in gaskets, packing, cement, and roofing, so workers and contractors at the Colonial Sugars Company site - especially those involved in maintenance, insulation removal, or post-incident cleanup before asbestos controls were widely enforced - could have experienced asbestos exposure.

Columbia Southern Chemical in Lake Charles, Louisiana operated as part of Columbia-Southern Chemical Corporation, the chemicals arm of Pittsburgh Plate Glass (later PPG Industries), and was known for chlor-alkali production that supplied chlorine, caustic soda, and related products to the regional petrochemical and plastics markets; operations at this Lake Charles, LA site were consistent with chlor-alkali practice and included brine preparation, diaphragm cell electrolysis, chlorine drying and liquefaction, caustic concentration, byproduct handling, and extensive utility and maintenance support (boilers, steam systems, pumps, compressors, and repair shops). The facility's era of operation coincided with widespread industrial use of asbestos: the diaphragm process relied on asbestos fiber diaphragms, and asbestos-containing insulation, gaskets, and packing were commonly used on heated piping and equipment, creating potential asbestos exposure risks for production workers, maintenance crews, and contractors during diaphragm fabrication and change-outs, insulation work, and turnarounds. Over time, the site's operations were integrated into PPG's Lake Charles works as technologies evolved, but historical materials and practices at Columbia Southern Chemical are the context for possible asbestos exposure at this location.

Columbia Southern Chemical Corp. in Lake Charles, Louisiana operated as a chemical manufacturing facility historically associated with Pittsburgh Plate Glass (later PPG Industries), producing chlor-alkali chemicals such as chlorine and caustic soda and supporting downstream vinyls-related production that served the Gulf Coast petrochemical sector; over time, the Lake Charles, LA site and its operations were incorporated into PPG's broader chemicals business and later corporate successors active in the area. As with many mid-20th-century chlor-alkali plants, possible asbestos exposure at this location could have occurred due to the use of asbestos-containing materials, including asbestos diaphragms in older electrolytic cells, thermal insulation on steam and process piping, boilers, and heat exchangers, and asbestos-containing gaskets and packing in pumps and valves, with heightened risk for maintenance and turnaround crews prior to the widespread shift to non-asbestos materials and stricter controls beginning in the 1970s-1980s.

The Columbia Southern Chemical Corporation facility in Lake Charles, Louisiana was part of PPG Industries' Columbia-Southern chemical operations and ran a chlor-alkali complex producing chlorine, caustic soda, and related basic chemicals that supported regional plastics and industrial markets; developed and expanded through the mid-20th century, the Lake Charles, LA plant relied on brine electrolysis units, evaporators, compressors, and extensive piping and utilities typical of Gulf Coast chemical manufacturing. As with many facilities of this type and era, asbestos-containing materials were used for thermal insulation on steam lines, boilers, turbines, pumps, and process vessels, and older chlor-alkali diaphragm cells employed asbestos fiber diaphragms, creating potential asbestos exposure risks for operators, pipefitters, insulators, maintenance crews, and contractors during installation, repairs, turnarounds, and demolition activities.

The Columbia Southern Chemical plant in Lake Charles, Louisiana was part of Columbia-Southern Chemical, the chemical division of PPG Industries, and for decades operated as a major chlor-alkali facility producing chlorine, caustic soda, hydrogen, and related chemical intermediates used by regional petrochemical and paper manufacturers; operations typically included brine treatment, electrolytic cell rooms, evaporators, compressors, boilers, and extensive process and steam piping across the Lake Charles, LA complex. Historically, workers at this location faced potential asbestos exposure common to mid-20th-century chemical plants, including from thermal insulation on pipes, boilers, turbines, and heat exchangers; asbestos-containing gaskets and packing in pumps, valves, and flanged joints; and, specific to older chlor-alkali diaphragm processes, asbestos fiber diaphragms used in electrolytic cells, with heightened risks for insulators, pipefitters, maintenance mechanics, operators, and contractors during repairs and turnarounds prior to modern controls and material substitutions.

For Columbia Sugar Co. in Caffery, Louisiana, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Columbia Sugar Co. in Franklin, Louisiana was part of the region's sugarcane industry, operating a plant that carried out typical sugar processing steps such as cane crushing, juice clarification, evaporation, crystallization, and packaging, supported by steam generation, boilers, turbines, extensive piping, centrifuges, and drying/conveying systems. As with many sugar mills and refineries built or maintained before asbestos use was curtailed, equipment and building systems at this site may have incorporated asbestos-containing materials for heat and fire resistance, including pipe and boiler insulation, gaskets, valve and pump packing, refractory products, and insulating boards, creating potential asbestos exposure for employees and contractors during operation, maintenance, repairs, and insulation removal. Trades at elevated risk could have included boiler operators, pipefitters, millwrights, mechanics, insulators, and electricians, with bystander exposure possible in enclosed processing areas where dust and fibers could become airborne. The Columbia Sugar Co. facility in Franklin, LA exemplified historic sugar-industry operations in southern Louisiana and the associated industrial hygiene risks common to that era.

Columbian Carbon Co operated a carbon black manufacturing facility in Eola, Louisiana, producing carbon black for tires, rubber goods, inks, and plastics; typical operations at the Eola, LA plant would have included furnace reactors, heat exchangers, dryers, baghouses, and packaging for rail or truck shipment, supported by on-site utilities and maintenance activities. While carbon black itself does not contain asbestos, industrial facilities of this era commonly used asbestos-containing materials for high-temperature insulation on boilers, steam and process lines, furnaces, and in gaskets and valve packing, so workers at the Columbian Carbon Co site - particularly insulators, pipefitters, maintenance crews, and contractors - could have encountered asbestos exposure during repair, removal, or overhaul of aging insulation and equipment.

Columbian Carbon Co in Franklin, Louisiana was part of a major carbon black manufacturing enterprise that supplied reinforcing fillers for tires and other rubber and plastic products; operations at facilities of this type typically involved furnace processes using heavy aromatic feedstocks to make carbon black, followed by pelletizing, storage, and shipment by rail and truck. The Franklin, LA plant, also associated historically with the Columbian Chemicals name, functioned as an industrial site serving regional and national customers. As with many mid-20th-century industrial plants, possible asbestos exposure at this location could have arisen from asbestos-containing insulation on high-temperature piping and equipment, boilers and furnaces, gaskets and packing in pumps and valves, and other thermal controls and building materials, with elevated risks for maintenance workers, pipefitters, electricians, and contractors during repairs, outages, or renovation - especially prior to tighter regulations and phase-outs in the 1970s-1980s.

The Columbian Carbon Co facility in St. Mary Parish, LA, located in Franklin, Louisiana, was a carbon black manufacturing plant that supplied the rubber and industrial markets, using high - temperature "furnace black" processes to convert heavy aromatic oils into carbon black, followed by collection in baghouses, pelletizing, drying, storage, and shipment by truck and rail; typical supporting utilities included boilers, steam and condensate systems, compressors, and fuel handling. As with many mid- to late - 20th - century process plants, potential asbestos exposure at this St. Mary Parish location could have arisen from thermal insulation on steam lines and boilers, gaskets and packing in pumps and valves, refractory or insulating materials on dryers and ducts, and asbestos - containing cements or textiles used for heat protection, with the highest risks historically during maintenance, repair, and contractor work that disturbed these materials before modern controls and substitutions were in place. While carbon black dust posed a separate occupational concern, any asbestos hazard would have been linked to building and equipment materials rather than the product itself.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Columbian Carbon Co - North Bend, LA - New T & NR Station No. 650 in St. Mary Parish, Louisiana is associated with operations of the former Columbian Carbon Company, a major U.S. producer of carbon black used by the rubber and chemical industries; typical activities at facilities like the North Bend, Louisiana site included high - temperature furnace production, pelletizing and bagging, storage in silos, and rail/truck loading supported by boilers, steam lines, process piping, dryers, baghouses, compressors, and pumps. Specific public details about this exact station are limited, but the general industrial profile for Columbian Carbon sites is well established. During the mid - 20th century, such equipment commonly incorporated asbestos - containing materials, including pipe and boiler insulation, gaskets, packing, refractory linings, and roofing, creating potential asbestos exposure risks for operators, maintenance and repair personnel, insulators, and contractors, with additional risk during teardown, renovation, or cleanup. This location appears on lists of workplaces where asbestos exposure may have occurred, and although confirmed incident records are not cited here, the materials and maintenance practices typical of carbon black plants of that era present credible pathways for exposure.

The Columbian Carbon Co North Bend Plant #21 in St. Mary Parish, Louisiana was part of the company's carbon black manufacturing operations supplying the tire and industrial rubber markets, with production typical of the era involving the furnace black process (high - temperature reactors, quenching, pelletizing, drying, and bagging). At facilities like this in St. Mary Parish, LA, potential asbestos exposure could have occurred due to the historical use of asbestos - containing materials for thermal insulation on boilers, steam lines, dryers, and reactors, as well as in gaskets, pump and valve packing, and refractory linings used in high - heat equipment; maintenance and repair activities traditionally posed the highest risk prior to stricter controls adopted in the late 1970s and 1980s. While detailed, site - specific public documentation is limited, the plant's operations and timeframe align with known industrial practices in Louisiana in which asbestos - containing materials were commonly used.

The Columbian Carbon Co - North Bend Plant #95 in St. Mary Parish, LA was a carbon black manufacturing facility where heavy aromatic oils were thermally decomposed in high-temperature reactors, with the produced carbon black collected in baghouses, pelletized, dried, and shipped for use in rubber and other industrial applications; while detailed site-specific history is limited, this St. Mary Parish, Louisiana operation would have utilized boilers, steam lines, dryers, reactors, and extensive piping typical of mid-20th-century carbon black plants. Because facilities of this type commonly used asbestos-containing insulation, gaskets, and packing on hot process and utility systems prior to regulatory changes in the 1970s-1980s, potential asbestos exposure could have occurred for production workers, maintenance staff, pipefitters, insulators, and contractors during installation, repair, removal, or turnarounds when those materials were disturbed; buildings and panels of the era may also have incorporated asbestos-cement components. Carbon black itself did not contain asbestos, but the presence and disturbance of asbestos-containing materials in equipment and infrastructure presented the primary exposure risk at the Columbian Carbon Co - North Bend Plant #95 in St. Mary Parish, LA.

The Columbian Carbon Co - North Bend Plant No. 95 in St. Mary Parish, Louisiana was part of the region's carbon black industry, associated with legacy Columbian Carbon/Columbian Chemicals operations that supplied reinforcing fillers to tire and rubber manufacturers; while specific public records about this site are limited, carbon black plants of this era typically used the furnace black process (burning heavy oils in reactors, quenching, cooling, conveying, pelletizing, drying, and bagging) supported by high - temperature utilities and equipment such as boilers, steam lines, dryers, compressors, and dust - collection systems, and its location within St. Mary Parish - whose parish seat is Franklin, Louisiana - places it in the Gulf Coast petrochemical corridor. Because industrial facilities built or operated before the 1980s frequently used asbestos - containing insulation, gaskets, and packing on boilers, piping, pumps, valves, and reactors, potential asbestos exposure at the North Bend Plant No. 95 could have occurred for production workers, maintenance and turnaround crews, pipefitters, insulators, and contractors during repair or demolition activities if asbestos materials were disturbed; anyone with historical work at the plant in St. Mary Parish, LA should be aware of this possibility.

The Columbian Carbon Co. site in North Bend, Louisiana was part of the company's carbon black manufacturing network, producing reinforcing carbon black via high - temperature furnace processes using petroleum feedstocks, with pelletizing, drying, bulk storage, and rail/truck shipping to customers in the tire, rubber, plastics, and ink industries; as such, the Columbian Carbon Co. - North Bend, LA facility operated with boilers, process heaters, furnaces, dryers, and extensive piping typical of this industry. Throughout much of the twentieth century, equipment and systems of this type commonly incorporated asbestos-containing materials - such as thermal insulation on pipes and boilers, refractory components, and gaskets and packing in pumps and valves - creating potential asbestos exposure for production workers, maintenance personnel, and outside contractors, especially during repairs, insulation removal/installation, and equipment overhauls. Detailed public information specific to this location is limited, but its processes and equipment were consistent with standard carbon black plant operations where asbestos use and related exposure risks were historically common.

Columbian Carbon Co.'s facility in St. Mary Parish, Louisiana was part of the company's carbon black manufacturing network (later known as Columbian Chemicals and now associated with Birla Carbon), producing carbon black primarily for tires, rubber goods, plastics, and inks using the furnace black process that involves combusting heavy aromatic feedstocks, quenching, pelletizing, drying, and baghouse filtration; the location is commonly associated with the Franklin, Louisiana industrial area within St. Mary Parish. Operations at such plants typically included reactors, boilers, dryers, compressors, and extensive piping systems, with high-temperature equipment and refractory-lined units. Possible asbestos exposure at the Columbian Carbon Co. - St. Mary Parish, LA site could have arisen from historical use of asbestos-containing thermal insulation on pipes and boilers, refractory materials in high-heat equipment, gaskets and packing in pumps and valves, and insulation on dryers and furnaces, especially before the 1980s; maintenance personnel, pipefitters, boiler operators, and contractors performing repairs or demolition would have had higher potential for contact if such materials were present. While site-specific asbestos findings are not detailed here, the era of construction and the high-temperature, heavy industrial processes characteristic of carbon black production indicate a credible potential for historical asbestos-containing materials and related occupational exposure at this facility.

Columbian Carbon Company, historically affiliated with Cities Service Company, operated a carbon black manufacturing facility in Lake Charles, Louisiana that supplied reinforcing fillers and pigments to the tire, rubber, and specialty materials markets. Typical operations at this site included the furnace black process using petroleum feedstocks, high-temperature reactors and furnaces, pelletizing and drying of product, packaging, and bulk loading for rail and truck shipment, supported by onsite utilities such as steam generation, compressors, and maintenance shops within the broader Lake Charles petrochemical complex. Because much of this type of industrial infrastructure built and maintained in the mid-20th century relied on heat-intensive equipment, workers and contractors at the Columbian Carbon Company facility in Lake Charles, LA could have encountered asbestos-containing materials used for insulating boilers, furnaces, dryers, and extensive steam and process piping, as well as in gaskets, pump and valve packing, refractory linings, and heat-resistant textiles; disturbance of these materials during maintenance, repairs, or retrofits represented the most likely avenues for possible asbestos exposure before modern controls and substitutions were implemented.

The Columbian Carbon Plant in Swartz, Louisiana was a carbon black manufacturing facility associated with Columbian Carbon Company (later Columbian Chemicals and now part of Birla Carbon), supplying reinforcing fillers for tires and other rubber products as well as pigments for plastics and inks; operations at the Swartz, LA site typically involved the furnace black process in which heavy aromatic oils were thermally decomposed in high - temperature reactors, with product collection, pelletizing, drying, storage, and shipment by rail and truck, supported by boilers, steam and process piping, pumps, valves, and baghouses. Located near Monroe in Ouachita Parish, the plant employed operators, maintenance personnel, and contractors to run units and perform turnarounds and repairs. As with many mid - 20th - century industrial facilities of this type, potential asbestos exposure at the Columbian Carbon Plant could have occurred before widespread phase - outs and regulations, particularly from insulation on boilers, furnaces/reactors, steam lines, and dryers, as well as from asbestos - containing gaskets, packing, and cements; maintenance and repair tasks by pipefitters, millwrights, insulators, and electricians posed the greatest risk when disturbing aging materials, although later abatement programs and material substitutions reduced these hazards.

The Columbian Chemical Co. facility in Franklin, Louisiana (St. Mary Parish) is a carbon black manufacturing plant historically operated by Columbian Chemicals Company, now part of Birla Carbon, producing carbon black used in tires, rubber products, plastics, coatings, and inks; operations typically involve the controlled thermal decomposition of hydrocarbons in reactors and furnaces, followed by collection, pelletizing, drying, storage, and shipment supported by boilers, compressors, and extensive piping and material-handling systems. With respect to potential asbestos exposure, like many older chemical and carbon black plants, legacy high-temperature equipment and building materials - such as insulation on steam lines and piping, boiler and duct insulation, refractory linings, gaskets, packing, and valve components - often contained asbestos prior to regulatory changes in the late 1970s-1980s; as a result, maintenance workers, operators, and contractors at the Columbian Chemical Co. site in Franklin, LA could have encountered asbestos-containing materials during repairs, turnarounds, or demolition activities, particularly before modern abatement and safety controls were in place.

Columbian Chemicals' facility in Franklin, Louisiana is an industrial plant historically engaged in the manufacture of carbon black, a reinforcing and pigmenting material used primarily in tires and other rubber and plastic products; operations typically involve the furnace black process, capture of particulate in baghouses, pelletizing/drying, and shipment by truck or rail, with supporting utilities such as high - temperature reactors, boilers, compressors, and steam systems operating under state and federal air permits. The site, commonly referenced as Columbian Chemicals - Franklin, LA and later associated with Birla Carbon following corporate acquisition, has the kinds of equipment and thermal systems characteristic of mid - 20th - century heavy industry. As with many facilities of this type and vintage, there was a potential for asbestos - containing materials to have been present in pipe and boiler insulation, gaskets, packing, and fireproofing; possible exposure pathways would have been greatest for maintenance and repair personnel, insulators, pipefitters, and contractors during tasks that disturbed aging insulation or components, particularly prior to the 1980s and during renovations or demolition.

Commercial Solvents - Sterling, LA refers to a Commercial Solvents Corporation location in Sterling, Louisiana associated with chemical manufacturing and solvent/intermediate processing, part of a company long known for producing industrial solvents and related chemical feedstocks. Operations at such facilities typically included distillation, blending, and storage of solvents, supported by utilities like boilers, steam lines, and pressure vessels, along with extensive piping, pumps, heat exchangers, and valves. Given industry practices through the late twentieth century, asbestos-containing insulation, gaskets, and packing were commonly used on this type of equipment, creating a potential for asbestos exposure to employees and contractors - particularly pipefitters, insulators, maintenance mechanics, and operators - during routine work, repairs, and turnarounds. Publicly available, site-specific documentation for the Commercial Solvents - Sterling, LA facility is limited, but it is listed among locations where occupational asbestos exposure may have occurred.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Commercial Solvents Corporation, a U.S. producer of industrial chemicals and solvents, is documented as having a facility in Sterlington, Louisiana, though detailed public information about the specific products made and the exact years of operation at this location is limited. In general, the company's operations involved manufacturing and distributing solvents and related chemical intermediates for industrial uses, which typically required boilers, steam systems, pumps, valves, reactors, and extensive piping. Because asbestos-containing insulation, gaskets, and packing were widely used in such equipment through at least the late 1970s, workers and maintenance contractors at the Commercial Solvents Corp. site in Sterlington, LA may have experienced possible asbestos exposure during routine operations, repairs, and turnarounds, as well as during removal or disturbance of aging insulation and gasket materials. This facility appears on lists of workplaces where asbestos exposure may have occurred, but publicly available records do not detail specific exposure incidents or site-specific asbestos products.

Commercial Solvents Corporation operated a chemical manufacturing facility in Sterlington, Louisiana, consistent with the company's broader focus on industrial solvents and specialty chemical intermediates; typical operations at the Sterlington, LA site would have included chemical reaction and separation processes, bulk storage and transfer of feedstocks and finished products, and extensive utilities such as boilers, steam systems, process piping, and maintenance shops to support continuous plant operations. As with many U.S. chemical plants built or expanded prior to the 1980s, asbestos-containing insulation, gaskets, packing, and fireproofing were commonly used on equipment like boilers, heat exchangers, pumps, and pipelines, creating potential asbestos exposure for production employees, pipefitters, insulators, and contractors during routine work, repairs, and turnarounds until such materials were phased out or better controlled. While publicly available details about specific product slates and an exact operating timeline at this Commercial Solvents Corporation location are limited, the site is known as an industrial chemical facility in Sterlington, Louisiana where asbestos exposure may have been possible.

The Commercial Solvents Plant in Sterlington, Louisiana was a long-running chemical manufacturing complex originally built and operated by Commercial Solvents Corporation, known at this location for producing nitroparaffins (such as nitromethane and nitroethane) and related organic solvent intermediates used in coatings, pharmaceuticals, and industrial formulations. Over time, the facility continued similar operations under successor ownership, most notably ANGUS Chemical Company (at times a subsidiary of Dow), and remained a significant employer in Sterlington, LA and the surrounding Monroe area. Typical operations included high-temperature nitration, steam and utility generation, distillation, and extensive use of pumps, piping, heat exchangers, and storage systems. As with many U.S. chemical plants constructed and expanded before the 1980s, asbestos-containing materials were commonly used for thermal insulation on boilers and steam lines, around reactors and heat exchangers, and in gaskets, packing, and valve components; maintenance work, turnarounds, and insulation removal or replacement would have presented the greatest potential for airborne asbestos exposure to workers and contractors at the Commercial Solvents Plant in Sterlington, Louisiana. While no specific exposure incidents are cited here, the facility's age and process profile indicate that asbestos exposure could have occurred at this site.

Confederate Memorial Hospital in Shreveport, Louisiana, was a state charity hospital that grew into a major safety - net and teaching facility for the region, operating for many years as Confederate Memorial Medical Center and ultimately serving as the primary training hospital for the LSU School of Medicine in Shreveport. Located in Shreveport, LA, it provided broad inpatient and outpatient services - such as emergency care, surgery, obstetrics, and specialty clinics - while supporting the education of physicians, nurses, and allied health professionals serving northwest Louisiana and the Ark - La - Tex. Over time the institution was renamed and integrated into LSU Health Shreveport's academic medical center, with operations continuing under state - university and later public - private management. As with many mid - 20th - century hospitals, facilities associated with Confederate Memorial Hospital likely contained asbestos - containing materials (for example, pipe and boiler insulation, floor tiles and mastics, fireproofing, and HVAC components), creating potential exposure risks for maintenance workers, contractors, and staff in mechanical spaces or during repair and renovation before modern abatement practices were established. Subsequent asbestos management and abatement efforts typically reduced ongoing risks, but historical exposure remains a concern for individuals who worked in or renovated the buildings during earlier periods.

Confederate Memorial Medical Center hospital in Shreveport, LA historically operated as a large, state-run charity and teaching hospital serving northwest Louisiana, providing full-service acute inpatient and outpatient care, emergency treatment, surgery, and a wide range of specialty clinics, and later served as a teaching hospital affiliated with LSU Health Sciences Center-Shreveport. Built and expanded during the mid-20th century, the facility supported training for medical students, residents, nurses, and allied health professionals while delivering safety-net services to the Shreveport community and surrounding region. As with many hospitals from that era, there is potential for past asbestos use in materials such as pipe and boiler insulation, sprayed-on fireproofing, floor and ceiling tiles, roofing, and HVAC components; maintenance and engineering personnel, custodial staff, and outside contractors involved in repairs, renovations, or demolition would have had the highest likelihood of exposure, while routine clinical roles faced lower incidental risk. Later modernization projects typically include asbestos abatement, but caution is warranted when disturbing older building areas or utility spaces at this location.

The Conoco facility in Lake Charles, Louisiana operated as a large, integrated petroleum refinery and logistics hub, processing a range of crude oils into gasoline, diesel, jet fuel, LPG, sulfur, and petrochemical feedstocks via crude and vacuum distillation, catalytic cracking, delayed coking, hydrotreating/hydrocracking, alkylation, sulfur recovery, and extensive storage, pipeline, rail, and marine operations; over time, ownership and branding evolved from Continental Oil (Conoco) to ConocoPhillips and later Phillips 66, though it is commonly referenced historically as Conoco - Lake Charles, LA. As with many mid-20th-century refineries, possible asbestos exposure at this site could have occurred - particularly before the 1980s - from insulation and refractory on boilers, furnaces, piping, turbines, heat exchangers, and FCC/coker units, as well as from gaskets, packing, and certain protective materials; the highest potential for exposure in Lake Charles, LA would have been during maintenance, repair, and turnaround activities where legacy asbestos-containing materials were disturbed, even as usage declined and abatement practices expanded in later decades.

Conoco (Continental Oil) operated petroleum refining and related process units in the Lake Charles, Louisiana area, commonly referred to as the Lake Charles refinery complex, where typical operations included crude oil distillation, catalytic cracking, reforming, hydrotreating, coking, sulfur recovery, and product blending to make transportation fuels and petrochemical feedstocks; over time the site was associated with Conoco and its successor companies as part of a larger Gulf Coast refining network serving regional and national markets. As with many mid-20th-century refineries, the Lake Charles, LA facilities likely incorporated asbestos-containing materials for high-heat service and fire protection, including insulation on piping, boilers, heaters, turbines, and pumps, as well as gaskets, packing, refractory, and fireproofing on structures; during maintenance, turnarounds, insulation removal, or equipment repairs, workers such as pipefitters, insulators, boilermakers, mechanics, laborers, and contractors could have encountered airborne asbestos fibers, with a potential for secondary (take-home) exposure.

The Conoco Oil Refinery in Sulphur, Louisiana refers to Conoco/ConocoPhillips' refining operations in the Lake Charles industrial corridor, historically tied to the large complex now operated as the Phillips 66 Lake Charles Manufacturing Complex in nearby Westlake, serving the Sulphur and Lake Charles area with fuels and petrochemical feedstocks. Operations at this Gulf Coast site have included crude and vacuum distillation, fluid catalytic cracking, reforming, hydrotreating, alkylation, delayed coking, sulfur recovery, and associated utilities and logistics (marine, pipeline, rail, and truck), producing gasoline, diesel, jet fuel, LPG, and chemical feedstocks for regional and export markets. Ownership and branding evolved as Conoco merged with Phillips in 2002 to form ConocoPhillips, and the downstream business later became Phillips 66 in 2012, with the Lake Charles complex continuing to anchor refining in Calcasieu Parish near Sulphur, LA. As with many refineries built or expanded during the mid-20th century, potential asbestos exposure at this location could have arisen from historical use of asbestos-containing insulation, gaskets, packing, refractory, and fireproofing on piping, boilers, furnaces, turbines, and heat exchangers; maintenance and turnaround work by crafts such as pipefitters, insulators, boilermakers, and contractors would have posed the greatest risk before modern abatement and control measures were implemented.

The Conoco Oil Refinery in Westlake, Louisiana - historically associated with Conoco/ConocoPhillips and now part of Phillips 66's Lake Charles Manufacturing Complex - is a major Gulf Coast facility that processes crude oil into transportation fuels and other refined products, with operations that include crude and vacuum distillation, catalytic cracking and hydrotreating, reforming, coking, sulfur recovery, large storage and blending, and product distribution via pipelines, rail, and marine docks on the Calcasieu Ship Channel. Located in West Lake, LA within Calcasieu Parish and the broader Lake Charles industrial corridor, the site produces gasoline, diesel, jet fuel, liquefied petroleum gases, petrochemical feedstocks, petroleum coke, and sulfur, and employs operations, maintenance, and contractor personnel typical of an integrated refining complex. As with many refineries built and expanded during the mid-20th century, asbestos-containing insulation, gaskets, packing, and refractory materials were commonly used on piping, boilers, heaters, pumps, valves, and process units, meaning workers such as insulators, pipefitters, boilermakers, and maintenance crews at the Conoco Oil Refinery could have faced asbestos exposure during routine work, turnarounds, or demolition - particularly before modern abatement programs and regulatory controls were implemented.

The Conoco oil refinery in Westlake, Louisiana - commonly known as the Lake Charles Refinery - was originally developed and operated by Conoco and later by ConocoPhillips; today the site operates as the Phillips 66 Lake Charles Manufacturing Complex, a large Gulf Coast operation with crude distillation, catalytic cracking, hydrotreating, and coking units producing gasoline, diesel, jet fuel, LPG, petroleum coke, and petrochemical feedstocks, supported by storage, pipeline connections, and marine docks on the Calcasieu Ship Channel. Located in Westlake, LA, the facility has been in industrial service since the mid-20th century and serves regional and export markets. As with many refineries of its era, historical use of asbestos-containing insulation, gaskets, packing, and fireproofing on boilers, heaters, piping, pumps, and turbines created potential asbestos exposure for operators, maintenance crews, and contractors - particularly during repairs and turnarounds before stricter controls and abatement practices were adopted in the 1980s - although ongoing management and remediation have reduced, but not entirely eliminated, the chance of encountering legacy asbestos during maintenance activities.

The Conoco Refinery in Lake Charles, Louisiana is a large Gulf Coast petroleum processing complex that has historically converted a range of crude oils, including heavier sour feedstocks, into transportation fuels and other products such as gasoline, diesel, jet fuel, liquefied petroleum gases, petroleum coke, and sulfur. Situated in the Lake Charles area with access to waterways, pipelines, rail, and storage tank farms, the site's operations typically include crude and vacuum distillation, fluid catalytic cracking, hydroprocessing (hydrotreating/hydrocracking), coking, reforming, sulfur recovery, utilities, and regular maintenance turnarounds. Historically associated with Conoco and later the ConocoPhillips/Phillips 66 downstream lineage, the facility is commonly known locally as the Lake Charles refinery. Like many refineries built and expanded during the mid-20th century, the Conoco Refinery in Lake Charles, LA likely used asbestos-containing materials for high - temperature insulation on piping, boilers, heaters, and FCC equipment, as well as in gaskets, valve packing, and fireproofing; as a result, trades such as insulators, pipefitters, boilermakers, and maintenance workers could have faced occupational asbestos exposure, particularly during repairs, removals, and turnarounds before stricter controls in the late 1970s and 1980s. Legacy asbestos materials may have remained in older units for years thereafter, posing disturbance risks during overhaul or demolition activities.

The Conoco Refinery in Westlake, Louisiana - commonly known today as the Lake Charles Refinery - began operations in the early 1940s and evolved into a large, complex facility with crude distillation, fluid catalytic cracking, delayed coking, hydrotreating, reforming, and alkylation units that produce gasoline, diesel, jet fuel, LPG, petrochemical feedstocks, petroleum coke, and sulfur; originally developed by Continental Oil (Conoco), the site later became part of ConocoPhillips and is now operated by Phillips 66, with logistics tied to pipelines, rail, and the Calcasieu Ship Channel in Westlake, LA. As with many U.S. refineries built and expanded before the 1980s, the Conoco Refinery presented potential asbestos exposure risks from insulation on piping, boilers, heat exchangers, pumps, and turbines, as well as asbestos-containing gaskets and packing used throughout processing units such as the FCC and coker; trades with elevated potential exposure included pipefitters, insulators, boilermakers, maintenance and turnaround crews, and contractors performing repairs or abatement, particularly during shutdowns or when disturbing older materials, even as later safety and abatement programs reduced these risks.

The Conoco Refinery (Lake Charles) in Westlake, Louisiana is a long-standing Gulf Coast petroleum refining complex located in the Lake Charles industrial corridor along the Calcasieu Ship Channel. Historically associated with Conoco and, following corporate changes, ConocoPhillips and later Phillips 66, the facility's operations focus on processing crude oil into transportation fuels such as gasoline, diesel, and jet fuel, as well as liquefied petroleum gases and petrochemical feedstocks, with distribution supported by marine, pipeline, and rail logistics. The refinery has been an important regional employer and a key node in Gulf Coast fuel supply. As with many refineries developed and expanded during the mid-20th century, equipment at the Westlake, LA site historically incorporated asbestos-containing materials for heat and fire resistance - commonly in pipe and vessel insulation, boilers and heaters, and in gaskets and packing - so employees and contractors performing maintenance, repairs, and turnarounds prior to the 1980s could have faced asbestos exposure; over time, abatement, enclosure, and improved protective practices were implemented to reduce these risks.

Conoco, Inc. operated a major petroleum refining complex in the Lake Charles, Louisiana area (commonly known as the Lake Charles Refinery, located in nearby Westlake) that began operating in the 1940s and processed crude oil into gasoline, diesel, jet fuel, liquefied gases, petroleum coke, and petrochemical feedstocks through units such as crude distillation, catalytic cracking, reforming, hydrotreating, coking, alkylation, and sulfur recovery, supported by extensive tankage, pipelines, and marine/rail terminals; over time the site transitioned from Conoco to ConocoPhillips and later Phillips 66, but it is historically identified with Conoco in Lake Charles, LA. Like many refineries of its era, the facility used asbestos-containing materials extensively, including thermal insulation on pipes, boilers, turbines, heat exchangers, and process heaters, refractory linings in cracking units, and asbestos gaskets and packing; operators, maintenance personnel, pipefitters, boilermakers, insulators, electricians, and contractors could have been exposed, particularly during repairs, turnarounds, and demolition before widespread asbestos phase-outs in the late 1970s and 1980s.

The Conoco, Incorporated - Lake Charles, LA facility was part of the Gulf Coast petroleum industry, where Conoco operated refining and related industrial activities in the Lake Charles, Louisiana area to process crude oil into transportation fuels and petrochemical feedstocks. Typical operations at this site included crude distillation, catalytic cracking, reforming, hydrotreating, and coking, supported by extensive tankage and product movement via pipeline, rail, and marine connections in the Calcasieu Parish industrial corridor. Like most mid-20th-century refineries, the facility historically used asbestos-containing materials for high-heat service and fireproofing, including insulation on piping, boilers, heaters, turbines, and heat exchangers, as well as gaskets and packing in pumps and valves. Maintenance, repair, and turnaround work could disturb these materials and release airborne fibers, creating potential exposure for operators, pipefitters, insulators, boilermakers, electricians, and contractors, with secondary risks from contaminated work clothing. Over time, asbestos use was curtailed and abatement programs were implemented under evolving OSHA and EPA regulations, though legacy materials could remain in older equipment. This Lake Charles, LA site served as a significant regional refining and logistics hub supporting fuels and petrochemical supply.

Consolidated Aluminum Co operated an industrial site in Lake Charles, Louisiana, associated with aluminum production and processing within the region's heavy-industry corridor; although publicly available, site-specific details on exact operating dates and product lines are limited, its activities would have included receiving, processing, and shipping aluminum materials along with typical plant utilities, maintenance, and materials handling found in Lake Charles, LA facilities. Regarding asbestos, aluminum plants of the mid-20th century commonly utilized asbestos-containing insulation for high-temperature equipment such as boilers, furnaces, ovens, and ducts, refractory linings, and gaskets and packing in pumps and valves, so workers involved in maintenance, repair, or demolition at the Consolidated Aluminum Co location may have faced potential asbestos exposure, especially prior to stricter controls adopted in the late 1970s and 1980s.

The Continental Oil Co. - Lake Charles, LA site refers to petroleum operations historically run by Continental Oil Company (later Conoco), part of the large oil and petrochemical complex in Lake Charles, Louisiana along the Calcasieu River and ship channel. Activities at this location typically included processing and handling crude and refined products, operating and maintaining process equipment and utility systems (steam lines, boilers, heat exchangers), and managing storage tanks, pipelines, and loading facilities that supported regional refining and distribution. Like most mid-20th-century oil facilities, the operation relied on asbestos-containing materials for high-heat service, including pipe and vessel insulation, refractory linings, gaskets, and valve and pump packing, creating potential exposure for employees and contractors - especially insulators, pipefitters, boilermakers, machinists, and operators - during routine maintenance, repairs, and turnarounds before tighter controls were adopted in the late 1970s and 1980s. While specific unit details for this site are limited in public summaries, the industrial setting and era make asbestos exposure a recognized concern at the Continental Oil Co. location in Lake Charles, LA.

The Continental Oil Co. facility in Westlake, Louisiana refers to the former Conoco (Continental Oil Company) petroleum refinery and manufacturing complex commonly associated with the Lake Charles industrial area. Developed in the mid-20th century and later operated under ConocoPhillips, the site is today better known as part of the Phillips 66 Lake Charles Manufacturing Complex, where operations have historically included crude oil refining and major process units such as distillation, catalytic cracking, reforming, hydrotreating, alkylation, and sulfur recovery to produce gasoline, diesel, jet fuel, LPG, and petrochemical feedstocks. As with many refineries of its era, the Westlake, LA site likely incorporated asbestos-containing materials for high-temperature service, including insulation on piping, boilers, heaters, turbines, and pumps, as well as gaskets, packing, and refractory linings in process vessels. Potential asbestos exposure would have been most significant for maintenance and turnaround crews, pipefitters, insulators, welders, and contractors, particularly before modern abatement and control practices became standard in the late 20th century. While current operations are subject to stringent health and safety regulations, historical work at the Continental Oil Co. - Westlake, LA location could have involved asbestos disturbance during repair, replacement, or demolition of insulated equipment.

Regarding Continental Oil Company - Lake Charles, LA, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.
