Boilermakers at United States Navy shipyards worked on and around the main propulsion boilers, auxiliary boilers, and pressure vessels that powered Navy warships — equipment that was insulated with asbestos throughout the mid-twentieth century. Boilermakers constructed, repaired, and overhauled ship boilers during construction and in shipyard drydock overhaul periods, working in boiler rooms and fireboxes where asbestos block insulation, asbestos insulating cement, and asbestos rope packing were standard materials. Publicly filed asbestos litigation records document Navy shipyard boilermakers specifically grouped alongside insulators as primary asbestos-exposed trades, personal testimony from Navy boilermakers, and epidemiological data identifying boilermakers among the occupational groups with the highest cumulative asbestos exposure rates in the shipyard workforce.

How Boilermakers Were Exposed to Asbestos
Boilermaker work at Navy shipyards placed workers in direct contact with asbestos-containing materials at every stage of boiler construction and overhaul:
Boiler insulation installation: New boilers were insulated with asbestos block, asbestos pipe covering, and asbestos insulating cement after boilermaker assembly — work performed in the same space and often overlapping with boilermaker final assembly work.
Firebox and furnace lining: Boiler fireboxes were lined with asbestos-containing refractory brick and refractory cement that boilermakers cut, fitted, and installed during construction and replaced during overhaul.
Asbestos rope packing: Boilermakers used asbestos rope packing to seal handhole and manhole cover gasket joints on boiler drums, headers, and pressure vessels — compressing asbestos rope into the oval sealing groove and torquing the cover bolts.
Boiler overhaul — insulation removal: Drydock overhaul of Navy boilers required removal of the old asbestos insulation from the boiler exterior before boilermakers could access the drum, shell, and tube bundle for inspection and repair — creating concentrated asbestos dust exposure in the partially confined space of the boiler room.
Gasket replacement: Boilermakers replaced asbestos gaskets in all boiler handhole covers, inspection ports, and steam piping connections during overhaul — cutting new gaskets from compressed asbestos sheet and torquing covers against the new material.
VA Claims and Legal Options for Boilermakers — Navy Shipyards Veterans
Navy veterans who served in boilermaker capacities at naval shipyards, and civilian boilermakers employed at Navy facilities, who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease, may qualify for:
- VA service connection under VA asbestos-claim guidance for veterans with documented boilermaker duties at naval shipyards
- Longshore and Harbor Workers’ Compensation Act (LHWCA) for civilian boilermakers employed at naval shipyards
- Civil claims against boiler manufacturers (Babcock & Wilcox, Foster Wheeler, Combustion Engineering, Cleaver-Brooks) and asbestos product manufacturers whose materials were used in Navy boiler construction and overhaul
Key documents:
- Employment records — Navy shipyard or contractor employment records documenting boilermaker trade classification
- Union records — Boilermakers (IBB) union membership records documenting shipyard work history
- DD-214 or service records — for Navy veterans with boilermaker duties
- Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
