History & Asbestos Use

The Capitol Building has been continuously renovated and expanded since its original construction, with major additions and modernizations occurring throughout the 20th century. Asbestos insulation was used extensively in the building's heating and ventilation systems, underground tunnels connecting Capitol complex buildings, and during mid-century renovation projects. The Architect of the Capitol has overseen ongoing asbestos abatement programs since the 1980s.

Exposure Details

Asbestos pipe insulation was present throughout the Capitol's steam tunnel system, mechanical rooms, and utility corridors. Floor tiles and ceiling materials in offices and corridors contained asbestos, and boiler rooms used asbestos insulation on heating equipment. Workers maintaining the building's aging infrastructure regularly disturbed asbestos materials in confined underground passages and mechanical spaces.
