History & Asbestos Use
The Chambers Works site began operations in 1892 and grew to encompass over 1,400 acres with hundreds of buildings producing dyes, chemicals, and specialty products. The facility was a major DuPont manufacturing hub through the twentieth century, employing thousands of workers at its peak. Asbestos was used extensively from the 1920s through the late 1970s in pipe insulation, gaskets, and fireproofing throughout the sprawling complex.
