Abstract: Two employees of a company that grinds nutshells into abrasive products were working in a mill room in the plant. They smelled smoke coming from the second or third catwalk levels above the mills. Both of them went to the third level to take a look. One of them (employee #2) noticed cinders around a conveyor motor on the second level. He went to scoop the cinders with a steel plate. The cinders ignited in a flash. The employee dropped the steel plate with the cinders and a second ignition took place. The other employee, who was still on the third level, jumped down to the second level, a distance of 8 feet. Both employees then evacuated the area and shut down the mill. Employee #1 suffered sprains in his foot, knee, and shoulder. Employee #2 suffered first and second degree burns on his face and on one of his arms. The fire appeared to have been caused by the use of unapproved electric equipment in a Class II, Division 2 hazardous location.
