Small fires were a part of the job at the Hoeganaes Corp. metal powder plant 30 miles northeast of Nashville. By early 2011, some workers later told investigators, they had become practiced in beating down the flames with gloved hands or a fire extinguisher.
The companys own product fueled the fires. Scrap metal rolls into therust-colored plant on the towns industrial periphery and is melted, atomized and dried into a fine iron powder sold to makers of car parts. Sometimes, powder leaked from equipment and coated ledges and rafters. Under the right conditions, it smoldered.
Wiley Sherburne, a 42-year-old plant electrician, sometimes told his wife how this dust piled up everywhere, she recalled. On quieter weekend shifts, he said he could hear the telltale popping sound of dust sparking when it touched live electricity.In the early morning of January 31, 2011, Sherburne was called to check out a malfunctioning bucket elevator that totes dust through the plant. Near his feet, electrical wires lay exposed. When the machine restarted, the jolt knocked dust into the air. A spark likely from the exposed wires, investigators later concluded turned the dust cloud into a ball of flame that engulfed Sherburne and a co-worker.
