At approximately 5:50 p.m., on June 5, 2000, the furnace Number 61 exploded when Employee #1 attempted to relight burner in zone No.1 using a hand held propane torch. When Employee #1 went to the furnace to make his first round, he started at burner No.1 and found it to be out. He closed the air and gas valves and attempted to relight the burner using an electric spark (spark plug) unsuccessfully so he again closed the valves and retrieved a hand held propane torch. He opened the gas valve, lit the torch and held it at the site glass, and he opened the air valve slightly. The furnace exploded at this point because all of the burners were out and the controllers had continued to introduce the gas/air mixture as if they were burning, causing a build-up of the explosive atmosphere inside the furnace. Once the spark from the torch was introduced the furnace exploded. The furnace operator was injured and a maintenance employee welding on covers approximately 10 ft. from the west end of the furnace was hit by the flying debris causing his death. Another employee was slightly injured when came to the aid of the two employees.
