Manufacturing, Manufacturing Plant Oak Ridge, TN – Fire in dust filtration system at manufacturing facility is contained by sprinkler system November 17, 2015 viking210 More than 20 employees were briefly evacuated when a fire alarm sounded in a manufacturing facility where products are made from depleted uranium, but there was no radiological release. The fire occurred about 9:30 a.m. Monday when dust in a filter system at Manufacturing Sciences Corp., S. Illinois Avenue, ignited. “All it takes is a spark to set it off,” Oak Ridge Fire Chief Darryl Kerley said. There’s a built-in sprinkler system that was activated and quelled the blaze. Kerley said there is “negative pressure” in the building where air is always pulled into it and is filtered. “Everything was contained in the building,” he said. Manufacturing Sciences is also involved in special metals handling.
