Four people suffered injuries after a small explosion Thursday at Letterkenny Army Depot in southern Pennsylvania.
The blast occurred at 7:20 a.m. ET in the paint shop of a large warehouse and sparked a fire, Letterkenny officials said. The warehouse had to be evacuated.
At least three of the injured were airlifted to hospitals, according to the depot. It said all employees had been accounted for.
The injured were burn victims, the Franklin County Fire Company said.
“The safety and well-being of our employees is our top priority,” said Col. Stephen Ledbetter, commander of the Letterkenny Army Depot, adding “the injured employees and their families are in our thoughts and prayers.”
“An apparent explosion resulting in a fire occurred in Bldg. 350 at Letterkenny Army Depot. The fire was contained and we have 100 percent accountability of our workforce,” depot officials said.
“We are conducting an investigation into the cause of the incident, so we know exactly what happened,” Letterkenny officials said.
Letterkenny Army Depot is just outside Chambersburg, PA, about 100 miles north of Washington. The 18,000-acre base employs 3,600 civilians, contractors and military personnel.
It was selected in 1941 as an ordnance depot. Today, it provides support for U.S. and allied air and missile defense forces.
