Blast at a Tennessee explosives plant leaves multiple people dead and missing

McEWEN, Tennessee: An explosion at a Tennessee military munitions plant left multiple people dead and missing on Friday, authorities said, and rescuers kept their distance for hours due to the burning field of debris and risks of secondary explosions.

The blast, which people reported hearing and feeling miles away, occurred at Accurate Energetic Systems in rural Tennessee. The company's website says it makes and tests explosives at an eight-building facility that sprawls across wooded hills in the Bucksnort area, about 97 kilometres southwest of Nashville.

"We do have several people at this time unaccounted for. We are trying to be mindful of families and that situation," Humphreys County Sheriff Chris Davis said at a news conference. "We do have some that are deceased."

The cause of the explosion, which Davis called "devastating," was not immediately known, and the investigation could take days, the sheriff said.

Aerial footage of the aftermath by WTVF-TV showed the explosion had apparently obliterated one of the facility's hilltop buildings, leaving only smoldering wreckage and the burnt-out shells of vehicles.

There's no further danger of explosions, and the scene was under control Friday afternoon, according to Grey Collier, a spokesperson for the Humphreys County Emergency Management Agency.

Emergency crews were initially unable to enter the plant because of continuing detonations, Hickman County Advanced EMT David Stewart said by phone. He didn't have any details on casualties.

Accurate Energetic Systems, based in nearby McEwen, did not immediately respond to a phone message seeking comment Friday morning.

"This is a tragedy for our community," McEwen Mayor Brad Rachford said in an email. He referred further comment to a county official.

Residents in Lobelville, a 20-minute drive from the scene, said they felt their homes shake and some people captured the loud boom of the explosion on their home cameras.

The blast rattled Gentry Stover from his sleep.

"I thought the house had collapsed with me inside of it," he said by phone. "I live very close to Accurate and I realized about 30 seconds after I woke up that it had to have been that."

State Rep. Jody Barrett, a Republican from the neighboring town of Dickson, was worried about the possible economic impact because the plant is a key employer in the area.

"We live probably 15 miles as the crow flies and we absolutely heard it at the house," Barrett said. "It sounded like something going through the roof of our house."

The Tennessee Emergency Management Agency confirmed there were injuries but wasn't sharing any numbers because the Department of Health hasn't confirmed them, spokesperson Kristin Coulter said by telephone. TEMA district coordinators have deployed to the area at the request of Hickman County, she said.
