⚙️ Shipyard Equipment That Contained Asbestos
For decades, asbestos was used in nearly every major mechanical system aboard commercial ships, tugboats, barges, ferries, military support vessels, and harbor equipment repaired at Illinois shipyards and ports. Shipbuilders selected asbestos because it could withstand extreme heat, resist fire, insulate steam systems, reduce friction, and extend the life of marine equipment operating under harsh conditions.
Asbestos-containing materials were installed throughout engine rooms, boiler rooms, cargo vessels, maintenance facilities, dry docks, and marine repair shops. Many workers handled these products daily without knowing they contained dangerous asbestos fibers.
Common asbestos-containing shipyard equipment included:
- Marine boilers
- Steam pipes
- Engine insulation
- Turbines
- Pumps
- Valves
- Gaskets
- Packing materials
- Brake systems
- Clutches
- Electrical panels
- Generators
- Fireproof wall panels
- Pipe insulation
- Deck insulation
- Exhaust systems
- Cement products
- Adhesives
- Fire blankets
Repairing or replacing these products frequently released microscopic asbestos fibers into enclosed work areas where workers could easily inhale them.
Many Illinois shipyard employees also worked in manufacturing plants, refineries, steel mills, and industrial facilities where they encountered many of the same asbestos-containing products. Learn more by visiting our Illinois Industrial Asbestos Exposure page.
🔥 Marine Boilers
Marine boilers were among the largest sources of asbestos exposure aboard commercial and military vessels. Boilers generated the steam needed to power propulsion systems, heating systems, pumps, and auxiliary equipment.
Because these systems operated under extreme temperatures and pressure, manufacturers surrounded boilers with thick layers of asbestos insulation.
Common asbestos products found around marine boilers included:
- Block insulation
- Boiler cement
- Pipe covering
- Insulating blankets
- Fireproof cloth
- Rope insulation
- Gaskets
- Packing materials
Boilermakers, mechanics, pipefitters, welders, and laborers frequently removed deteriorated insulation to inspect boilers or replace damaged components.
Repair work commonly involved:
- Removing insulation
- Replacing boiler tubes
- Scraping gaskets
- Installing new insulation
- Repairing steam valves
- Cleaning boiler compartments
These activities released asbestos fibers that could remain suspended inside boiler rooms for hours.
💨 Steam Pipes and Marine Insulation
Steam systems carried high-pressure steam throughout ships to power machinery and provide heat.
Nearly every steam pipe aboard older vessels was wrapped with asbestos insulation.
Common insulation materials included:
- Pipe covering
- Asbestos cloth
- Insulating cement
- Pipe lagging
- Fire-resistant blankets
- Molded insulation
- Rope insulation
Pipefitters routinely removed insulation before replacing damaged pipes, valves, elbows, and fittings.
Over time, insulation became brittle from heat, moisture, vibration, and age. Even minor repairs could cause insulation to crumble into airborne dust.
Steam systems were found throughout:
- Engine rooms
- Boiler rooms
- Cargo compartments
- Crew quarters
- Galley areas
- Mechanical spaces
- Maintenance rooms
Employees working nearby often inhaled asbestos fibers despite never directly removing insulation.
🚢 Marine Engines and Engine Rooms
Engine rooms contained some of the highest concentrations of asbestos aboard older vessels.
Marine engines generated tremendous heat and required extensive insulation to protect nearby equipment and reduce fire hazards.
Common asbestos-containing engine components included:
- Engine insulation
- Exhaust insulation
- Gaskets
- Valve packing
- Pump packing
- Heat shields
- Fireproof panels
- Pipe insulation
Mechanics rebuilding engines frequently removed worn insulation, replaced gaskets, repaired pumps, serviced valves, and cleaned engine compartments.
Because engine rooms were enclosed spaces with limited ventilation, asbestos fibers often remained airborne long after repairs were completed.
⚙️ Pumps, Valves, Gaskets, and Packing Materials
Marine pumps and valves controlled steam, fuel, water, lubricants, and compressed air throughout the vessel.
Many pumps and valves relied on asbestos packing to prevent leaks while allowing moving shafts and valve stems to operate.
Workers routinely performed tasks such as:
- Removing packing
- Cleaning valve housings
- Scraping gasket surfaces
- Installing replacement packing
- Replacing gaskets
- Rebuilding pumps
- Repairing valves
Old packing often broke apart during removal, releasing asbestos fibers into the surrounding work area.
Mechanics also cut replacement gaskets from asbestos gasket sheets, creating additional dust during installation.
⚡ Electrical Equipment
Shipboard electrical systems also contained asbestos because of its excellent heat resistance and insulating properties.
Electrical products commonly containing asbestos included:
- Electrical panels
- Switchgear
- Motor insulation
- Generator insulation
- Arc chutes
- Fuse panels
- Fire-resistant electrical boards
- Wiring insulation
Electricians frequently disturbed these materials while repairing motors, generators, lighting systems, electrical controls, and distribution panels.
Electrical work often occurred alongside mechanical repairs, increasing the risk of bystander asbestos exposure.
🚧 Dry Docks and Ship Repair Operations
Illinois dry docks handled major vessel repairs that required extensive demolition, rebuilding, and equipment replacement.
Workers commonly performed:
- Engine overhauls
- Boiler replacements
- Pipe removal
- Structural repairs
- Insulation replacement
- Electrical upgrades
- Pump rebuilding
- Valve repairs
- Fireproofing removal
Grinding, drilling, cutting, sanding, and demolition work frequently disturbed asbestos-containing materials throughout the vessel.
Repair crews often worked simultaneously in confined spaces, increasing exposure risks for everyone aboard the ship.
👷 High-Risk Shipyard Occupations
Many shipyard occupations involved repeated exposure to asbestos-containing materials throughout a worker’s career.
High-risk occupations included:
- Boilermakers
- Shipfitters
- Pipefitters
- Steamfitters
- Marine mechanics
- Electricians
- Welders
- Machinists
- Millwrights
- Laborers
- Insulators
- Carpenters
- Painters
- Maintenance workers
- Crane mechanics
- Dry dock workers
- Dock mechanics
- Harbor maintenance workers
- Supervisors
- Equipment operators
Many employees worked in multiple departments over the course of their careers, increasing the number of asbestos-containing products they encountered.
Former military personnel employed in civilian shipyards may also have experienced asbestos exposure while serving aboard Navy vessels. Learn more on our U.S. Military Veterans Asbestos Exposure and Navy Ship Asbestos Exposure pages.
👕 Secondary (Take-Home) Asbestos Exposure
Many Illinois shipyard workers unknowingly carried asbestos fibers home on their clothing, boots, gloves, and tools.
Family members could be exposed while:
- Washing dusty work clothes
- Shaking uniforms
- Cleaning work boots
- Vacuuming contaminated vehicles
- Handling work equipment
- Hugging workers returning home
Spouses and children have later developed mesothelioma after years of repeated secondary exposure to asbestos fibers brought home from shipyards.
Workers and families researching historical exposure locations should also review our Illinois Asbestos Exposure Sites guide.
📋 Documenting Shipyard Asbestos Exposure
Former shipyard workers often cannot remember the names of individual asbestos products they handled decades ago. However, claims can frequently be supported using employment history, maintenance records, coworker testimony, and historical evidence documenting asbestos use throughout the maritime industry.
Helpful documentation includes:
- Shipyard employer
- Employment dates
- Job titles
- Dry dock assignments
- Vessel names
- Departments worked
- Maintenance duties
- Coworker names
- Union membership
- Medical records
- Railroad Retirement or employment records, when applicable
Former workers should focus on describing the work they performed and the equipment they repaired rather than trying to identify every asbestos-containing product by name.

🩺 Asbestos-Related Diseases Among Illinois Shipyard and Port Workers
Thousands of Illinois shipyard and port workers were exposed to asbestos while building ships, repairing marine equipment, replacing insulation, maintaining boilers, rebuilding engines, servicing steam systems, and working throughout dry docks and waterfront repair facilities. Because asbestos-related diseases often take decades to develop, many workers were not diagnosed until years after retiring.
The most common asbestos-related diseases include:
- Mesothelioma
- Asbestos lung cancer
- Asbestosis
- Pleural plaques
- Pleural thickening
- Other asbestos-related respiratory diseases
Most asbestos-related illnesses develop 20 to 50 years after exposure. Even workers exposed for relatively short periods may later develop serious medical conditions.
Former shipyard employees, dock workers, marine mechanics, electricians, welders, pipefitters, insulators, laborers, and maintenance personnel should tell their physicians about any history of working around asbestos-containing materials.
