An explosion Tuesday at a sprawling ammunition plant near Kansas City, Missouri, killed one worker and injured four others, the U.S. Army said. The blast at the Lake City Army Ammunition Plant in Independence, just east of Kansas City, occurred in a building where chemicals are mixed, Army officials. Workplace safety experts with the U.S. Department of Labor's Occupational Safety and Health Administration also will be looking into the blast. The 77-year-old plant, created to help arm the U.S. military effort in the run-up to World War II, makes small-caliber ammunition and tests its reliability. Dulles, Virginia-based contractor Orbital ATK, the biggest maker of small-caliber ammunition for the U.S. Department of Defense, runs the plant.
