Asbestos at the North Shore Sanitary District: What You Need to Know

Why Asbestos-Containing Materials Were Used at Wastewater Treatment Facilities

Asbestos-containing materials were the industry standard in twentieth-century municipal and industrial construction—not an anomaly. Engineers and contractors specified them because they:

Provided thermal insulation on boilers, pipes, and steam systems
Resisted fire in boiler rooms, electrical rooms, and mechanical spaces
Held up against the corrosive chemicals used in wastewater treatment
Cost less than non-asbestos alternatives through the 1970s
Dampened noise in pump stations and blower buildings

Manufacturers including Johns-Manville, Owens-Corning, Owens-Illinois, Armstrong World Industries, and W.R. Grace dominated this market for decades. What these companies knew—and concealed—was that their products were killing workers. That concealment is the foundation of asbestos litigation today.

When Asbestos-Containing Materials Were Reportedly Present

Facilities built or substantially renovated between approximately 1930 and the late 1970s most commonly incorporated asbestos-containing materials. The North Shore Sanitary District operated facilities during this era that reportedly contained asbestos-containing materials, placing workers at potential exposure risk from the 1940s through the 1990s.

Exposure risk did not end with original construction. Workers may have been exposed:

During routine maintenance of boilers, pumps, and piping systems
During repair and replacement of asbestos-containing insulation and gaskets
During renovation and facility expansion projects
During abatement activities where proper containment protocols were allegedly not followed

Who Was at Risk: Trades and Job Classifications

Pipefitters and Plumbers

Pipefitters and plumbers working at the North Shore Sanitary District may have been heavily exposed while:

Installing, repairing, and replacing pipe insulation allegedly containing asbestos from manufacturers including Johns-Manville, Armstrong World Industries, and Owens-Corning
Cutting and fitting asbestos-containing pipe covering—including products marketed under trade names such as Kaylo and Thermobestos—releasing airborne fibers in enclosed spaces
Working with asbestos-containing gaskets and packing materials on flanged connections, valves, and pumps
Laboring in confined pump rooms and utility tunnels where asbestos fibers accumulated with no ventilation

Old, friable pipe covering doesn’t just shed fibers—it generates clouds of them. Members of unions including Heat and Frost Insulators Local 1 (St. Louis) and Plumbers and Pipefitters UA Local 562 performing this work may have faced repeated, sustained exposure over entire careers.

Insulators (Thermal Insulation Workers)

Insulators carry among the highest asbestos-related disease rates of any trade—because their work involved direct, daily handling of asbestos-containing materials:

Cutting and fitting pipe covering products
Installing and removing boiler insulation and block insulation
Applying asbestos cement coating products
Removing old, deteriorated insulation during renovation and repair

Products allegedly supplied by manufacturers including Johns-Manville, Owens-Illinois, and Combustion Engineering—marketed under trade names such as Aircell, Monokote, and Thermobestos—generated extreme airborne fiber concentrations during removal and installation. Members of Heat and Frost Insulators Local 1 (St. Louis) and Heat and Frost Insulators Local 27 (Kansas City) performing this work may have experienced some of the most intense occupational asbestos exposure documented in the litigation. Claims involving insulators frequently result in substantial Missouri mesothelioma settlements.

Boilermakers

Boilermakers working on boiler and steam systems may have encountered asbestos-containing materials including:

Boiler block insulation and lagging allegedly from manufacturers such as Johns-Manville and Combustion Engineering
Rope and blanket insulation on boiler doors and access hatches
Refractory cement products applied to boiler surfaces
Gaskets on boiler fittings, manholes, and inspection ports

Annual boiler inspections and recurring maintenance may have required repeated removal and replacement of asbestos-containing rope gaskets and refractory materials—meaning this was not a one-time exposure but a chronic one.

Electricians

Electricians may have been exposed through:

Asbestos-containing arc chute liners and thermal insulation in electrical panels and switchgear
Asbestos-containing insulation on older wiring systems
Working in boiler rooms, pipe chases, and mechanical spaces where asbestos fibers settled on every horizontal surface
Asbestos-containing ceiling tiles and wall panels in electrical rooms

Electricians regularly absorbed bystander exposure—fibers generated by insulators and pipefitters in adjacent spaces, with no warning and no protection. Courts have consistently recognized bystander exposure as a legitimate basis for asbestos claims.

Maintenance Mechanics, Millwrights, and Plant Operations Personnel

Direct employees and contractors performing day-to-day maintenance at the district’s facilities may have been exposed while:

Inspecting and maintaining equipment containing deteriorating asbestos insulation
Responding to equipment failures requiring emergency repair or replacement of asbestos-containing components
Cleaning and sweeping areas where asbestos dust had accumulated
Performing janitorial and environmental remediation tasks without respiratory protection

Construction Workers and Contractors

Workers employed in facility expansion, renovation, and new construction from the 1930s through the 1980s may have been exposed during:

Installation of new infrastructure incorporating asbestos-containing materials allegedly supplied by Johns-Manville, Owens-Corning, Georgia-Pacific, and Celotex
Demolition and removal of existing structures and equipment
Abatement activities where proper containment was allegedly not maintained

The Products: What Was Reportedly Used and Who Made It

Pipe Insulation and Covering

Wastewater treatment facilities contain miles of pipe carrying raw sewage, treated effluent, sludge, and chemical solutions. Many of these pipes were reportedly insulated with asbestos-containing products including:

Pipe covering marketed under trade names such as Kaylo, Thermobestos, Unibestos, and Superex, allegedly supplied by Johns-Manville, Owens-Corning, Eagle-Picher, and Owens-Illinois
Asbestos-containing cement used to seal pipe insulation joints, allegedly supplied by Johns-Manville and Owens-Corning
Gaskets on flanged fittings allegedly supplied by Garlock Sealing Technologies and Crane Co.
Valve covers and fitting covers containing asbestos-containing components allegedly supplied by Armstrong World Industries

Workers cutting, fitting, or removing these materials inhaled respirable fibers—in some cases at levels the manufacturers’ own internal studies identified as dangerous.

Boiler and Steam System Insulation

The North Shore Sanitary District’s facilities reportedly contained boilers and steam generators used for process and facility heating. These systems typically incorporated:

Boiler block insulation applied directly to boiler surfaces, allegedly from Johns-Manville, Combustion Engineering, and Owens-Corning
Rope and blanket insulation used to seal boiler doors and access hatches, allegedly supplied by Johns-Manville and Armstrong World Industries
Asbestos-containing refractory cement applied to boiler surfaces
Steam pipe insulation throughout distribution networks, marketed under trade names such as Aircell and Monokote
Heat exchanger insulation on sludge digester heating systems and other process equipment, allegedly from Combustion Engineering and W.R. Grace

Gaskets, Packing, and Sealing Materials

Pumps, valves, and flanged connections at wastewater treatment facilities may have contained:

Asbestos-containing gasket materials allegedly from Garlock Sealing Technologies and Crane Co., used on pump casings, valve bodies, and flanged connections
Packing materials in pump and valve seals, allegedly supplied by Johns-Manville and Garlock Sealing Technologies
Rope gaskets used in boiler doors and inspection ports
Flexible asbestos cord used in various sealing applications, allegedly from Owens-Illinois

These materials required regular replacement during routine maintenance—meaning exposure was not occasional but built into the job.

Electrical Equipment

Older electrical equipment at the facility may have contained:

Arc chute liners in electrical switchgear and circuit breakers, allegedly supplied by manufacturers including Combustion Engineering
Thermal insulation in panelboards and power distribution equipment
Asbestos-containing wire and cable insulation in older wiring systems, allegedly from Eagle-Picher
Backing and reinforcement materials in electrical equipment

Building Materials

The facility’s structures may have contained asbestos-containing materials including:

Ceiling tiles and suspended ceiling systems marketed under trade names such as Gold Bond from manufacturers including Armstrong World Industries and Georgia-Pacific
Wall panel insulation in mechanical rooms and boiler rooms, allegedly from Johns-Manville and Celotex
Floor tile and underlayment from manufacturers including Owens-Corning and Georgia-Pacific
Spray-applied fire-resistant coatings marketed under trade names such as Monokote, allegedly supplied by W.R. Grace and Combustion Engineering
Exterior building insulation allegedly from Johns-Manville and Owens-Corning

How Fibers Spread Through the Work Environment

Workers may have been exposed to fibers contaminating their entire work environment because:

Asbestos fibers released during insulation removal or maintenance settled on surfaces, work benches, and equipment throughout the facility
Fibers accumulated in ventilation systems and recirculated through occupied spaces
Bystander workers inhaled fibers generated in adjacent work areas
Facilities reportedly lacked effective containment systems and negative pressure isolation during maintenance work

Family Members: Take-Home Exposure Claims

Asbestos fibers cling to clothing, hair, skin, and tools. Family members may have been exposed to asbestos-containing dust when:

Washing work clothes contaminated with asbestos fibers
Embracing workers returning home from contaminated environments
Cleaning vehicles used to transport tools and equipment
Laundering bedding and textiles in machines previously used for contaminated work clothing

Occupational health literature has documented this take-home exposure pattern extensively, and Missouri courts have recognized it as a basis for independent legal claims. If a family member who never set foot at the North Shore Sanitary District has developed mesothelioma or asbestos-related cancer, their exposure history still warrants evaluation by an experienced asbestos cancer lawyer in Missouri.

The Science: Why Mesothelioma Takes Decades to Appear

Mesothelioma has a latency period of 20 to 50 years between initial asbestos exposure and diagnosis. That means a pipefitter who handled asbestos-containing pipe covering at the North Shore Sanitary District in 1970 may not receive a diagnosis until 2020 or later. This latency is not a legal obstacle—courts and trust funds routinely
