During the 1930s, hundreds of workers, from a tunnel construction project near the town of Gauley Bridge, West Virginia, died from silicosis, a lung disease caused by expsure to silica dust. The employer did not use methods known at the time to control the dealy dust. For the full story, read Martin Cherniack’s book, The Hawk’s Nest Incident: America’s Worst Industrial Disaster. New Haven: Yale University Press, 1986. This clip was taken from the 1979 film, ‘Can’t Take No More," from Federal OSHA. The entire 27 minute film is available on the Internet Archives.
