Where Asbestos Was Found on Army Installations

Common Exposure Locations

Barracks

Contained asbestos in floor tile, ceiling tile, wall insulation, and boiler-connected heating systems.

Motor Pools

Heavy contamination from brake dust, clutch repairs, gaskets, and insulation on vehicle parts.

Tank Depots

Asbestos used in armored vehicle brakes, pipe insulation, engine components, and maintenance areas.

Hangars

Large amounts of ACM in roofing, insulation blankets, fireproofing, and aircraft component storage.

Administrative Offices

Pre-1980 buildings often used asbestos ceiling tile, insulation, HVAC duct wrap, and floor tile.

Family Housing

On-base homes commonly contained asbestos siding, roofing shingles, flooring, and pipe insulation.

Boiler Rooms

Extremely concentrated asbestos in boilers, steam pipes, valves, gaskets, and high-heat insulation.

Steam Plants

High exposure from massive insulated pipe systems, turbines, pumps, and thermal blankets.

WWII-Era and Vietnam-Era Buildings

Nearly all structures built before 1980 used extensive ACM in walls, roofing, insulation, and mechanical systems.
