Abstract: A coal dust explosion occurred at a coal tripper at an electric power generation plant. The explosion propagated throughout the coal handling areas of the main building. There was major structural and fire damage to these areas. Electrical systems were also damaged by the explosion, with debris striking and causing faults in electric cables. The faults caused some switchgear and an oil-filled transformer outside the building fail, which resulted in fires. Two electric utility and fifteen contractor employees working at the site sustained various injuries because of the explosion and fire. Eight of the injured employees were hospitalized.
