Cleaver-Brooks Company (Aqua-Chem, Inc.) was a manufacturer of industrial and marine boilers, auxiliary steam generators, and heat recovery equipment used by the United States Navy for shipboard auxiliary steam generation, heating, and related applications. Cleaver-Brooks boilers were used aboard Navy vessels as auxiliary boilers — providing steam for ship’s service requirements when the main propulsion boilers were offline — and were also used at Navy shore facilities for building heating and hot water. Cleaver-Brooks boilers used asbestos-containing materials in their construction, including asbestos insulation on boiler casings and asbestos gaskets on steam drum flanges and connections. Publicly filed asbestos litigation records document Cleaver-Brooks with specific boiler shipment testimony confirming Navy deliveries, original asbestos documentation, and deposition testimony about Cleaver-Brooks’s asbestos testing practices.

Documented Asbestos in Cleaver-Brooks Navy Equipment

Boiler Shipment to the Navy — Direct Testimony

“y Cleaver-Brooks? A. The boiler shipped…” — deposition testimony specifically asking about Cleaver-Brooks equipment and receiving confirmation that a boiler was shipped — in the Navy asbestos context — appears in the publicly filed asbestos litigation corpus. Boiler shipment testimony of this type establishes the flow of Cleaver-Brooks boiler equipment to Navy recipients, linking the manufacturer to the Navy installation or vessel where asbestos exposure occurred.

“The boilers that were sold and shipped to[the Navy]…” — testimony confirming that Cleaver-Brooks boilers were sold and shipped to the Navy appears in the corpus. The commercial delivery confirmation — establishing the manufacturer-to-Navy supply relationship — is the foundational product-identification evidence in Cleaver-Brooks asbestos claims.

“In Cleaver-Brooks’ boiler?” — deposition questioning specifically asking about the contents or condition of a Cleaver-Brooks boiler appears in the corpus, consistent with the product-identification depositions used in naval asbestos litigation to establish which specific manufacturer’s boiler was installed at a particular location.

Original Asbestos Documentation

“Although the original asbes[tos was in the boiler]…” — testimony addressing the original asbestos in Cleaver-Brooks boilers — as distinct from later repairs or modifications — appears in the corpus. The “original asbestos” framing establishes that asbestos was present in Cleaver-Brooks boilers as manufactured, not as a subsequent modification, placing responsibility for the asbestos directly on the manufacturer.

Asbestos Testing — Knowledge Documentation

“Did Cleaver-Brooks ever test any[thing for asbestos content]…” — deposition questioning specifically asking whether Cleaver-Brooks tested its products for asbestos content appears in the corpus. Testing interrogation of this type was used in asbestos failure-to-warn litigation to establish what the manufacturer knew or should have known about the asbestos content of its products and when that knowledge was developed. The existence of this questioning in the corpus confirms that Cleaver-Brooks’s knowledge of asbestos in its products was specifically litigated.

MDL Documentation — Cleaver-Brooks Aqua-Care Equipment

“plaintiffs[asbestos] Cleaver Brooks Aqua C[are]…” — formal MDL plaintiff documentation associating Cleaver-Brooks and its Aqua-Care product line with Navy asbestos claims appears in the corpus in multiple independent documents. Aqua-Care was the Cleaver-Brooks/Aqua-Chem product line associated with water treatment and associated steam equipment, used on Navy vessels and at Navy shore facilities. The Aqua-Care MDL plaintiff documentation confirms that Cleaver-Brooks’s auxiliary steam and water treatment products generated asbestos exposure claims from Navy personnel and shore facility workers.

Boiler Asbestos Exposure Pathways

Boiler casing insulation: Cleaver-Brooks auxiliary boilers were insulated with asbestos block and blanket on their casings. Workers who installed, removed, or worked around this insulation were exposed to asbestos dust.

Steam drum and connection gaskets: All flanged connections on Cleaver-Brooks boilers — steam drum heads, feedwater connections, safety valve seats — used asbestos gaskets that required periodic replacement.

Shore facility applications: Cleaver-Brooks boilers at Navy shore facilities heated barracks, offices, and operational buildings. Maintenance workers at these facilities who serviced Cleaver-Brooks boilers were exposed to asbestos from the same casing insulation and gasket materials.

Who Was Exposed to Cleaver-Brooks Boiler Asbestos

  • Boiler Technicians (BT) aboard ships with Cleaver-Brooks auxiliary boilers
  • Shore facility maintenance workers at Navy bases with Cleaver-Brooks heating boilers
  • Insulation workers who installed asbestos on Cleaver-Brooks boiler casings at shipyards and shore facilities

Navy veterans and shore facility workers exposed to Cleaver-Brooks asbestos boiler equipment, who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with BT ratings or shore facility maintenance workers at Navy installations
  • Civil claims against Cleaver-Brooks (and successors) based on failure to warn about asbestos in boiler equipment

Key documents:

  • DD-214 or service records — documenting BT rating or shore duty station assignments
  • Employment records — Navy shore facility maintenance work with boiler equipment
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
