⛏️ DUMBs – Deep Underground Military Bases and Asbestos Exposure
The Hidden Asbestos Risk Beneath the Surface of National Defense
⚠️ Overview: Asbestos in Deep Underground Military Bases (DUMBs)
Deep Underground Military Bases (DUMBs) are covert, fortified installations constructed beneath the Earth’s surface for strategic military operations, storage, research, and continuity of government activities. Built primarily during the Cold War era, these underground complexes relied heavily on asbestos-containing materials for fireproofing, thermal insulation, and soundproofing in their confined environments.
Due to limited ventilation, enclosed workspaces, and long-term occupancy, asbestos exposure in DUMBs posed an intensified health risk for military engineers, contractors, and personnel. Today, many veterans who worked on or served in these subterranean bases are being diagnosed with mesothelioma, lung cancer, and asbestosis.
🧱 Why Asbestos Was Used in Underground Bases
| Function | Asbestos Applications |
|---|---|
| Fireproofing | Spray-on fireproofing, cement panels, insulation boards |
| Thermal Insulation | Pipe wrapping, boiler insulation, duct coverings |
| Structural Integrity | Asbestos in concrete additives, tunnel reinforcement materials |
| Electrical Safety | Arc shields, circuit breaker panels, wiring insulation |
| Acoustic Dampening | Asbestos-laced panels in communication and control rooms |
With a focus on survivability and containment, DUMBs required materials that could withstand extreme conditions, making asbestos a common construction choice.
🧰 Common Areas of Exposure in DUMBs
-
Tunnels and corridors lined with asbestos-coated structural materials
-
Boiler rooms insulated with asbestos blankets and pipe wrappings
-
Communication hubs using asbestos-laced acoustic panels
-
Ventilation shafts where damaged ductwork released airborne fibers
-
Machinery rooms with asbestos in gaskets, brake pads, and turbines
-
Living quarters and control rooms built with asbestos ceiling tiles, wall panels, and insulation
🧍 Personnel at Risk of Exposure
| Role | Exposure Risk |
|---|---|
| Military engineers | Direct involvement in base excavation and construction using asbestos components |
| Contracted tunnel workers | Worked with asbestos-laced concrete, ventilation, and sealing systems |
| Electricians & HVAC crews | Repeated contact with insulated wires, ducts, and switchgear |
| Operations personnel | Long-term exposure in poorly ventilated, enclosed environments |
| Maintenance teams | Repaired equipment and infrastructure containing asbestos |
🏗️ Suspected or Known Underground Installations with Asbestos Use
While most DUMBs are classified, some well-known or declassified locations where asbestos was likely present include:
-
Cheyenne Mountain Complex (Colorado) – Communications, NORAD operations, and hardened underground structure
-
Raven Rock Mountain Complex (Pennsylvania) – Continuity of government site with extensive infrastructure
-
Mount Weather Emergency Operations Center (Virginia) – FEMA and executive branch continuity facility
-
Dugway Proving Ground (Utah) – Chemical/biological testing with underground components
-
Site R and Fort Detrick (Maryland/Pennsylvania) – Research and medical defense installations
-
Los Alamos National Laboratory (New Mexico) – Deep-level infrastructure with legacy asbestos usage
-
Tonopah Test Range (Nevada) – Underground weapons and aviation research
🏭 Manufacturers of Asbestos Products Used in Underground Construction
These companies are known to have supplied asbestos-containing materials used in military construction and electrical systems:
-
Johns-Manville – Insulation, cement panels, and fireproof materials
-
Owens Corning – Pipe and duct insulation
-
Raybestos-Manhattan – Brake and gasket materials in underground equipment
-

🩺 Long-Term Health Risks for DUMB Personnel
Exposure to asbestos in DUMBs can result in serious illnesses, including:
-
Mesothelioma – Aggressive cancer of the lung or abdominal lining
-
Lung Cancer – Especially among veterans with long-term exposure
-
Asbestosis – Progressive scarring of lung tissue
-
Pleural Effusion or Thickening – Respiratory complications from asbestos buildup
Given the enclosed environments, even minimal fiber release could lead to high-dose exposure.
