Cleaver-Brooks Company: Asbestos Product History and Occupational Exposure Reference

Cleaver-Brooks Company is a manufacturer of industrial and commercial boiler systems headquartered in Thomasville, Georgia. Founded in 1929, the company became one of the most widely recognized names in packaged boiler manufacturing, supplying heating and steam generation equipment to industrial plants, hospitals, schools, refineries, and commercial facilities throughout the United States. According to asbestos litigation records, Cleaver-Brooks boilers and associated equipment manufactured and distributed prior to 1978 contained asbestos-containing components that allegedly exposed workers across multiple trades and industries to hazardous asbestos fibers.

This reference article is intended to assist workers, family members, and legal professionals researching occupational asbestos exposure histories involving Cleaver-Brooks equipment.

Company History

Cleaver-Brooks was established in 1929 with a focus on engineering more efficient and economical boiler systems for industrial and commercial customers. The company is credited with pioneering the concept of the “packaged boiler” — a pre-assembled, factory-built unit that could be shipped and installed more quickly than field-erected alternatives. This innovation made Cleaver-Brooks equipment especially attractive to facilities seeking to reduce installation time and labor costs.

Throughout the mid-twentieth century, the company expanded its product lines to include firetube and watertube boilers, burner management systems, and associated heating components. Cleaver-Brooks equipment was installed in a vast range of settings, including manufacturing plants, power generation facilities, shipyards, military installations, and large institutional buildings. The widespread distribution of the company’s products across American industry during the peak decades of asbestos use — roughly the 1940s through the mid-1970s — placed Cleaver-Brooks boilers at the center of numerous workplaces where asbestos exposure is now documented.

The company remained operational through the twentieth century and into the twenty-first, eventually becoming part of larger industrial holding structures. Its current operations continue in the boiler and combustion equipment market, though asbestos-containing materials were phased out of its products by 1978.

Asbestos-Containing Products

According to asbestos litigation records, Cleaver-Brooks manufactured and supplied boiler systems and related equipment that contained asbestos in multiple components prior to 1978. Court filings document that asbestos was used in these products primarily for its heat resistance, insulating properties, and durability under conditions of high temperature and pressure — all of which are characteristic of boiler operation environments.

Package Firetube Boilers

Plaintiffs alleged that Cleaver-Brooks package firetube boilers were manufactured with asbestos-containing insulation applied to the boiler shell, doors, and internal surfaces. Firetube boilers operate by routing hot combustion gases through tubes submerged in water, a process that generates sustained high heat. Court filings document that asbestos gaskets, rope packing, and block or blanket insulation were incorporated into these units. Workers who performed installation, maintenance, and repair of firetube boilers — including the removal and replacement of worn gaskets and insulation — may have encountered friable asbestos materials during routine service tasks.

Watertube Boilers

According to asbestos litigation records, Cleaver-Brooks watertube boilers also incorporated asbestos-containing materials, particularly in insulation applied to headers, drums, and steam and water lines associated with these systems. Watertube boilers operate under higher pressure than firetube designs, requiring extensive insulation to manage heat and protect workers. Plaintiffs alleged that during the manufacturing period prior to 1978, asbestos cloth, board, and block insulation were standard components in Cleaver-Brooks watertube systems. Bystander workers and maintenance personnel who worked in proximity to these boilers during repair operations could have been exposed to asbestos fibers disturbed during service activities.

Burner Management Systems

Court filings document that Cleaver-Brooks burner management systems — the control and ignition assemblies integral to boiler combustion operations — were insulated with asbestos-containing materials during the period of documented asbestos use. Plaintiffs alleged that because burner management systems are located in direct proximity to the combustion zone, the asbestos insulation used in these components was subject to repeated high-heat cycling, which could accelerate material degradation and fiber release. Technicians who regularly serviced, adjusted, or replaced burner components may have encountered disturbed asbestos insulation as part of routine maintenance activities.

Occupational Exposure

According to asbestos litigation records, the workers most frequently identified in connection with Cleaver-Brooks asbestos exposure claims include those employed in industrial maintenance and mechanical trades, as well as workers in industries where Cleaver-Brooks boilers were commonly installed.

Industrial Maintenance Workers

Plaintiffs alleged that industrial maintenance workers — including boilermakers, pipefitters, millwrights, and stationary engineers — faced repeated asbestos exposure during the upkeep and repair of Cleaver-Brooks boiler systems. Maintenance tasks such as replacing gaskets, removing deteriorated insulation, cleaning fireside passages, and adjusting burner components reportedly generated airborne asbestos dust in enclosed boiler rooms and mechanical spaces. Court filings document that these workers often performed tasks on Cleaver-Brooks equipment in confined areas with limited ventilation, conditions that may have concentrated fiber levels during disturbance activities.

Insulators and Pipe Coverers

According to asbestos litigation records, insulators who applied, removed, or repaired the thermal insulation on Cleaver-Brooks boilers and associated piping systems are among the trades most frequently associated with high-intensity asbestos exposure. The application of asbestos block, blanket, and cement insulation to boiler exteriors — as well as its removal during reinsulation projects — produced significant fiber release.

Power Plant and Utility Workers

Court filings document that Cleaver-Brooks boilers were widely used in power generation and utility facilities during the mid-twentieth century. Workers employed in these facilities, including power plant operators and maintenance technicians, may have been regularly exposed to asbestos from Cleaver-Brooks equipment over the course of extended careers.

Shipyard and Military Installation Workers

Plaintiffs alleged that Cleaver-Brooks boiler equipment was installed in some shipyard and military installation settings, expanding the population of potentially exposed workers beyond traditional industrial worksites. Workers in these environments who serviced boiler systems may have faced exposure conditions similar to those documented in industrial plant settings.

Secondary Exposure

Court filings document claims involving secondary or take-home asbestos exposure, in which family members of workers who serviced Cleaver-Brooks boiler equipment were allegedly exposed to asbestos fibers carried home on work clothing and equipment. While secondary exposure is generally considered lower in intensity than direct occupational exposure, it has been associated with asbestos-related disease diagnoses in some documented cases.

Cleaver-Brooks is classified as a Tier 2 company for purposes of this reference — meaning the company has been named in asbestos litigation and is the subject of documented court filings and plaintiff allegations, but has not established a dedicated asbestos bankruptcy trust fund of the type administered through Chapter 11 reorganization proceedings.

According to asbestos litigation records, Cleaver-Brooks has been named as a defendant in asbestos personal injury lawsuits filed by industrial maintenance workers, boilermakers, pipefitters, insulators, and others who allege exposure to asbestos-containing components in Cleaver-Brooks boiler systems manufactured prior to 1978. Plaintiffs in these cases alleged that the company knew or should have known of the hazards associated with asbestos use in its products and failed to provide adequate warnings to workers and end users.

Because no Cleaver-Brooks asbestos trust fund currently exists, individuals with potential exposure claims cannot file directly with an independently administered trust. Persons who believe they were exposed to asbestos from Cleaver-Brooks products and have received a diagnosis of an asbestos-related disease — including mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease — may pursue claims through civil litigation against the company directly, or potentially through trust claims filed against other manufacturers whose products were used alongside Cleaver-Brooks equipment on the same jobsites.

If you or a family member worked around Cleaver-Brooks boilers — particularly between the 1940s and 1978 — and have been diagnosed with mesothelioma, lung cancer, asbestosis, or another asbestos-related condition, you may have legal options.

Key points to understand:

  • No Cleaver-Brooks trust fund exists. Claims against Cleaver-Brooks must be pursued through direct civil litigation rather than a trust filing process.
  • Other trust funds may apply. Workers who handled Cleaver-Brooks equipment often worked alongside asbestos-containing products from other manufacturers that do have established trust funds. An asbestos attorney can identify all potential sources of compensation based on your full work history.
  • Exposure documentation matters. Records showing the specific facility, job duties, time period, and type of equipment involved strengthen asbestos exposure claims. Employment records, union records, coworker testimony, and facility maintenance logs are all potentially useful.
  • Statutes of limitations apply. Deadlines for filing asbestos claims vary and are typically measured from the date of diagnosis rather than the date of exposure. Prompt consultation with an experienced asbestos attorney is advisable following a diagnosis.

Workers and families researching Cleaver-Brooks exposure history are encouraged to consult with legal counsel experienced in asbestos personal injury matters to evaluate the full range of legal remedies available given their specific circumstances and diagnosis.
