One killed, four injured in Missouri ammunition plant explosion

Explosion at Army Ammunition Plant

One employee is dead and three others are hurt after an explosion Tuesday in a mixing building at Lake City Army Ammunition Plant in Independence.

The U.S. Army said Lawrence Bass, from Blue Springs, died Tuesday after the blast at the Lake City Ammunition Plant in Independence.

"I want to express my condolences to the family of the Lake City Army ammunition employee who died today".

"The four injured employees were evaluated on scene and refused further treating", Barati said in an email.

The facility is owned by the service but operated by Orbital-ATK and produces more than 1 billion rounds of small-caliber ammunition each year. The factory also operates the North Atlantic Treaty Organisation test center. But he says OSHA investigators are heading to the scene.

Jim Nickels, vice president and general manager of Orbital ATK, said the explosion happened in a building where workers mix chemicals into the primer that goes into all small-caliber munitions.

The plant is on almost 4,000 acres with 408 buildings, 43 magazines, nine warehouses, 11 igloos and storage capacity of 707,000 square feet. It claims to have produced 17 billion rounds of small-caliber ammunition at the Lake City facility for US and allied troops.

The property holds more than 400 buildings, including nine warehouses. It has a governmental staff payroll of $2.9 million.

The plant sits on 3,935 acres in Independence, CBS affiliate KCTV reports. A spokeswoman said no other details, including what caused the explosion, were immediately available.

According to the Kansas City Star, previous explosions in December 1990 and March 1981 killed and injured workers at Lake City.
