Seabees Equipment & Machinery Asbestos Exposure
U.S. Navy Seabees built and maintained military bases, airfields, roads, barracks, warehouses, utilities, ports, and other facilities around the world. Their construction mission required extensive use of heavy equipment, vehicles, generators, boilers, pumps, electrical systems, welding equipment, and HVAC machinery.
For much of the 20th century, asbestos-containing materials were widely used where resistance to heat, friction, fire, and electrical hazards was important. As a result, Seabees who operated, repaired, maintained, or worked near certain older military equipment and machinery may have encountered asbestos-containing components.
Exposure could occur during routine maintenance and repair when workers disturbed deteriorated insulation, gaskets, packing, brake components, electrical insulation, and other asbestos-containing materials.
Veterans diagnosed with mesothelioma, asbestos-related lung cancer, or another asbestos-related disease may have questions about where their exposure occurred and what compensation or VA benefits may be available.

Seabees Construction Equipment Asbestos Exposure
Heavy construction machinery was fundamental to the Seabee mission. Bulldozers, graders, loaders, excavators, cranes, and other equipment were used to clear land, construct roads, prepare airfields, excavate foundations, and support military construction.
Older equipment could incorporate asbestos-containing friction products, gaskets, insulation, and heat-resistant components. Mechanics and equipment operators could be exposed when these materials deteriorated or were disturbed during servicing.

Seabee Vehicles Asbestos Exposure
Seabees depended on trucks and other vehicles to move personnel, construction materials, tools, fuel, and equipment.
Historically, asbestos was used in some vehicle friction components, particularly brakes and clutches, as well as certain gaskets and heat-resistant parts. Repair and maintenance could disturb these materials and create exposure opportunities.

Seabees Vehicle Equipment Asbestos Exposure
Vehicle maintenance was essential for keeping Seabee construction operations moving. Mechanics and maintenance personnel could work on braking systems, clutches, engines, exhaust-related components, gaskets, and other parts.
The greatest potential for exposure generally occurred when asbestos-containing components were worn, damaged, removed, replaced, or otherwise disturbed.

Seabees Boiler Equipment Asbestos Exposure
Boilers and heating systems historically represented an important potential source of occupational asbestos exposure because asbestos was frequently used in high-temperature applications.
Seabees working around older boiler systems could encounter insulation, gaskets, packing, and other heat-resistant materials during installation, operation, repair, and maintenance.

Seabees Generator Equipment Asbestos Exposure
Portable and stationary generators supplied electricity at construction sites, temporary installations, military bases, and remote locations.
Older generator and power equipment could contain heat-resistant or electrical materials that incorporated asbestos. Maintenance work that required opening equipment, replacing gaskets, servicing electrical components, or removing deteriorated insulation could increase the possibility of disturbing asbestos-containing materials.

Seabees Electrical Equipment Asbestos Exposure
Asbestos was historically incorporated into certain electrical products because of its resistance to heat and fire.
Seabee electricians and maintenance personnel could encounter older electrical insulation, panels, arc-resistant components, wiring-related materials, and other equipment while constructing or repairing military facilities.

Seabees Welding Equipment Asbestos Exposure
Welding, cutting, and metal fabrication were common parts of construction and repair work.
Historically, asbestos-containing heat-resistant materials could be used around high-temperature operations. Workers performing welding or working nearby could encounter asbestos-containing protective or insulating materials, particularly when older materials were damaged or disturbed.

Seabees Pump Equipment Asbestos Exposure
Pumps were used for water systems, fuel handling, drainage, utilities, construction operations, and other military applications.
Older pumps frequently relied on gaskets and packing materials designed to withstand heat, pressure, and demanding operating conditions. Some historical products contained asbestos.
Repairing or replacing these components could release fibers when asbestos-containing materials were scraped, cut, removed, or deteriorated.

Seabees HVAC Equipment Asbestos Exposure
Seabees constructed and maintained heating, ventilation, and air-conditioning systems in military buildings and facilities.
Older HVAC systems and surrounding mechanical areas could contain asbestos insulation, duct materials, gaskets, pipe insulation, and other heat-resistant products. Renovation and maintenance could disturb these materials.

How Seabees Could Encounter Asbestos
Seabee equipment exposure was not limited to the person directly repairing a particular machine.
Potential exposure could occur while:
- Operating older construction machinery
- Performing preventive maintenance
- Repairing engines and mechanical systems
- Replacing brakes or clutches
- Removing old gaskets and packing
- Maintaining boilers and generators
- Repairing pumps and HVAC systems
- Performing electrical work
- Working beside mechanics and maintenance crews
- Cleaning equipment and maintenance areas
Disturbing asbestos-containing materials can release microscopic fibers into the surrounding air. These fibers can be inhaled and may remain in the body for decades.
Equipment Components That Could Contain Asbestos
Depending on the equipment, manufacturer, and period of use, historical asbestos-containing components could include:
- Brake linings and friction materials
- Clutch components
- Gaskets
- Valve and pump packing
- Thermal insulation
- Boiler insulation
- Pipe insulation
- Electrical insulation
- Heat-resistant materials
- Certain protective materials used around high-temperature work
The presence of asbestos cannot be determined simply from the age or appearance of a component. Equipment records, manufacturers, product documentation, military records, and other historical evidence may help establish whether asbestos-containing products were present.
Seabee Equipment Maintenance and Asbestos Exposure
Maintenance and repair could create greater exposure potential than simply operating intact equipment.
Removing an old gasket, replacing worn brake components, servicing insulated machinery, or repairing a boiler or pump could physically disturb asbestos-containing material.
Mechanics were not necessarily the only personnel affected. Other Seabees working in the same garage, equipment yard, mechanical room, shop, or construction area could potentially breathe airborne fibers generated by nearby work.
Health Risks From Asbestos Exposure
Asbestos exposure is associated with serious diseases that may not become apparent until decades after exposure.
These include:
- Malignant mesothelioma
- Lung cancer
- Asbestosis
- Pleural disease and other asbestos-related conditions
The long latency period is particularly important for veterans. A Seabee exposed while serving decades ago may only recently have developed an asbestos-related illness.
Seabees, Asbestos Lung Cancer and Mesothelioma
Mesothelioma is strongly associated with asbestos exposure. Asbestos exposure can also cause lung cancer, and smoking can greatly increase lung-cancer risk among asbestos-exposed individuals.
A veteran diagnosed many years after military service may therefore need to reconstruct where and how exposure occurred.
Equipment type, Seabee occupation, duty station, construction assignment, maintenance responsibilities, years of service, and the products used during that period can all be important when investigating a possible exposure history.
Secondhand Exposure to Seabee Families
Asbestos fibers could also be carried away from a workplace on contaminated work clothing and other materials.
Historically, family members who handled or laundered contaminated clothing could experience secondary or household exposure.

Help for Seabees and Their Families
A diagnosis of mesothelioma or asbestos-related lung cancer decades after military service can make determining the source of exposure difficult.
Former Seabees and their families may need to investigate military assignments, occupations, construction projects, equipment, manufacturers, maintenance duties, and civilian employment when building an exposure history.
Depending on the circumstances, veterans and families may have options involving VA disability benefits, asbestos trust funds, lawsuits, or other forms of compensation.
