Investigation Report: Combustible Dust Fire and Explosions, Corbin, Kentucky, February 20, 2003   [open pdf - 5MB]

"In investigating this incident, the U.S. Chemical Safety and Hazard Investigation Board (CSB) determined that combustible phenolic resin dust that had accumulated throughout the facility fueled the explosion. The investigation identified the following root causes for the February 20 incident: CTA Acoustics, Inc. management did not implement effective measures to prevent combustible dust explosions.; The CTA cleaning and maintenance procedures for production lines did not prevent the accumulation of unsafe levels of combustible dust on elevated flat surfaces.; The CTA incident investigation program did not ensure that all oven fires were investigated and that underlying causes were identified and resolved; The Borden Chemical product stewardship program did not explicitly convey to CTA the explosive hazards of phenolic resins; and The original building design and subsequent building modifications did not effectively address the fire and explosion hazards associated with combustible dusts." Key issues discussed include: combustible dust hazard awareness, work practices, building design, and product stewardship.
