History & Asbestos Use
Pearl Harbor has been a major naval installation since the early 1900s, and Hickam Field (later Hickam AFB) was established in the 1930s; both expanded massively during World War II. The Pearl Harbor Naval Shipyard repaired and overhauled thousands of ships built with asbestos throughout their piping, boilers, and machinery, while Hickam's hangars, administrative buildings, and housing were constructed with asbestos materials. Asbestos remained in routine use until federal exposure limits tightened in the late 1970s, and the two installations merged into a joint base in 2010. Hawaii's tropical heat accelerated deterioration of asbestos materials in older buildings.
