Asbestos, once hailed as a miracle material for its heat-resistant and insulating properties, turned out to be a silent killer aboard naval and merchant ships. Engine room workers—machinists, boilermen, and firemen—were among the most heavily exposed. Their duties placed them in direct contact with asbestos-insulated pipes, boilers, and machinery on a daily basis. For many, this exposure led to mesothelioma, asbestosis, and other deadly diseases decades later.
In this article, we dive deep into engine room roles that led to asbestos exposure, supported by firsthand accounts from veterans and shipyard workers who witnessed the dangers before they were widely acknowledged.

1. Why the Engine Room Was a Hotbed for Asbestos Exposure
Engine rooms were the heart of the ship—cramped, hot, noisy, and dense with machinery that generated extreme heat. To control this heat and prevent fires, shipbuilders covered boilers, pipes, pumps, gaskets, and turbines in asbestos-containing insulation.
From the 1930s through the late 1970s, asbestos was a standard component of naval architecture. Its use was particularly heavy during World War II and the Cold War, when military shipbuilding surged.
Key exposure points in engine rooms included:
- Asbestos-wrapped steam pipes
- Insulated turbines and boilers
- Asbestos brake linings and gaskets
- Fireproofing on walls and bulkheads
Even maintenance and repair tasks could disturb asbestos dust, making it airborne and easily inhalable.
2. Duties and Tasks That Exposed Workers to Asbestos
The daily work of engine room personnel often brought them in direct contact with asbestos fibers. Here are specific duties that led to the highest risk of exposure:
a. Boiler Maintenance
Boilers were covered in asbestos lagging (a form of insulation). When workers scraped or repaired these coverings, the fibers would flake off into the air.
“We used to wrap and unwrap the boilers all the time for maintenance. Nobody wore masks. Dust was just part of the job.”
— Tom McMillan, U.S. Navy veteran, 1965–1972
b. Pipefitting and Insulation Repair
Pipes throughout the engine room carried high-pressure steam and were insulated with asbestos cloth or sprayed coatings. When the insulation cracked or needed replacement, mechanics had to remove it by hand.
c. Gasket and Valve Repairs
Asbestos gaskets and valve packings were used to prevent leaks in high-temperature environments. Removing these involved scraping or grinding, releasing toxic dust.
d. Machinery Overhaul
Routine overhauls of engines and turbines required workers to disturb asbestos-laden parts and insulation.
“Every time we tore down an engine, there was asbestos everywhere—on the casings, the joints. We had no idea it was dangerous.”
— James “Skip” Darnell, Merchant Marine engineer, 1958–1979
3. Firsthand Accounts from Veterans and Ship Workers
John Rivera – U.S. Navy Machinist’s Mate (1961–1969)
“Back then, we thought asbestos was just part of the job. I remember brushing the dust off my clothes after crawling behind the boilers. Now I have pleural plaques and shortness of breath. I was never warned.”
Linda Parsons – Shipyard Electrician (Norfolk, VA)
“We rewired control panels in the engine rooms. The panels had asbestos fireproofing behind them. When we drilled through the walls, the dust was like smoke. We all breathed it in.”
Frank Walters – U.S. Coast Guard, Engine Room Technician
“My job was to replace gaskets and pump seals. We used to scrape out the old ones with wire brushes. The asbestos would flake like snow. If I’d known what I was inhaling, I would’ve refused the job.”
Collective Testimony from Merchant Marine Veterans
Many Merchant Mariners in the post-WWII era were exposed for years while working on commercial cargo ships. A 1992 survey by the Maritime Asbestos Victims Association found that over 60% of engine room workers interviewed reported direct contact with asbestos-laden parts without any protective equipment.
4. Health Consequences of Asbestos Exposure
Asbestos fibers, once inhaled, become lodged in the lungs and surrounding tissue. Diseases may take 20 to 50 years to develop, making it a latent but deadly hazard.
Primary diseases linked to exposure:
- Mesothelioma – A rare cancer of the lung lining, almost exclusively caused by asbestos
- Asbestosis – Chronic scarring of lung tissue
- Lung Cancer
- Pleural Effusion and Plaques
Case Example: Harold Jennings
Harold, a retired Navy boilerman, was diagnosed with mesothelioma in 2003—30 years after his service ended. He recalled using his bare hands to tear asbestos wrap off hot pipes.
“They didn’t give us respirators or tell us to be careful. They just said, ‘Get it done.’ Now I’m paying for it with every breath.”
5. Delayed Justice: Legal Battles and Compensation
After the health risks of asbestos became public, thousands of veterans and ship workers filed lawsuits against asbestos manufacturers and the government.
Key Developments:
- 1989 EPA Partial Ban on Asbestos – Restricted new uses, but many ship materials were already in place.
- Asbestos Trust Funds – Over $30 billion has been set aside to compensate victims from bankrupt asbestos manufacturers.
- Veterans Affairs (VA) Compensation – Navy veterans can apply for disability benefits if they were exposed during service.
However, proving exposure often requires detailed ship records and medical documentation.
“We had to fight for years to get any recognition. The companies just denied everything. But the scars in our lungs don’t lie.”
— Earl Patterson, retired machinist
6. Modern Reforms and Current Risk Status
Are Engine Rooms Still Dangerous?
Modern ships use alternative insulating materials. Since the 1980s, regulations have significantly reduced asbestos usage in U.S. shipbuilding. However, older ships, especially in developing countries or military reserves, may still contain asbestos.
Safety Measures Now in Place:
- Asbestos abatement protocols
- Protective gear for workers
- Clear labeling of asbestos materials
- Periodic health screenings
Still, thousands of veterans and shipyard workers from earlier generations continue to face health challenges due to past exposure.
7. Conclusion
The engine room was once the lifeline of ships—and, tragically, a silent death trap for many who worked there. Duties that seemed routine—scraping gaskets, wrapping pipes, grinding machinery—exposed workers to clouds of asbestos fibers.
Thanks to whistleblowers, survivors, and medical researchers, the dangers of asbestos are now undeniable. Firsthand accounts from machinists and boilermen not only humanize this crisis—they demand justice and remembrance.
If you or a loved one worked in a ship’s engine room and are now facing health issues, consider reaching out to an asbestos attorney or your local VA office. The time to act is now.
