Summary
Investigation of the fatal phenolic-resin dust explosions at CTA’s Kentucky insulation plant examines oven operation, baghouse performance, cleaning practices and elevated dust deposits. Laboratory testing and logic-tree analysis support findings on hazard communication, fire protection and unresolved earlier fires. Recommendations address dust accumulation, training, nonroutine operating procedures and corrective action.
