McEWEN, Tenn. (AP) — Officials were investigating a blast that leveled an explosives plant in rural Tennessee, as families of the 18 people missing and feared dead waited anxiously Saturday for answers.

The explosion Friday morning at Accurate Energetic Systems, which supplies and researches explosives for the military, scattered debris over at least a half-mile (800-meter) area and was felt by residents more than 15 miles (24 kilometers) away, said Humphreys County Sheriff Chris Davis.

Aerial footage showed the company’s hilltop location smoldering and smoky Friday, with just a mass of twisted metal, burned-out shells of cars and an array of debris left behind.

Davis, who described it as one of the worst scenes he’s ever seen, said multiple people were killed. But he declined to say how many, referring to the 18 missing as “souls” because officials were still speaking to family.

“What we need right now is we need our communities to come together and understand that we’ve lost a lot of people,” he said.

Signs near the site on Saturday asked for prayers for the families.

The company’s website says it processes explosives and ammunition at an eight-building facility that sprawls across wooded hills in the Bucksnort area, about 60 miles (97 kilometers) southwest of Nashville. It's not immediately known how many people work at the plant or how many were there when the explosion happened.

Davis said investigators are trying to determine what happened and couldn't say what caused the explosion.

Accurate Energetic Systems, based in nearby McEwen, said in a post on social media on Friday that their “thoughts and prayers" are with the families and community impacted.

“We extend our gratitude to all first responders who continue to work tirelessly under difficult conditions,” the post said.

The company has been awarded numerous military contracts, largely by the U.S. Army and Navy, to supply different types of munitions and explosives, according to public records. The products range from bulk explosives to landmines and small breaching charges, including C4.

When the explosion occurred, 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 told The Associated Press. “I live very close to Accurate and I realized about 30 seconds after I woke up that it had to have been that.”

Tennessee Gov. Bill Lee posted on the social platform X that he is monitoring the situation and asked “Tennesseans to join us in prayer for the families impacted by this tragic incident.”

A small group gathered for a vigil Friday night at a nearby park, clutching candles as they prayed for the missing and their families and sang “Amazing Grace."

The U.S. has a long history of deadly accidents at workplaces, including the Monongah coal mine explosion that killed 362 men and boys in West Virginia in 1907. Several high-profile industrial accidents in the 1960s helped lead President Richard Nixon to sign a law creating the Occupational Safety and Health Administration the next year.

In 2019, Accurate Energetic Systems faced several small fines from the U.S. Department of Labor for violations of policies meant to protect workers from exposure to hazardous chemicals, radiation and other irritants, according to citations from OSHA.

In 2014, an explosion occurred at another ammunition facility in the same small community, killing one person and injuring at least three others.
