Tennessee authorities announced Saturday that no survivors have been recovered from a massive explosion at a rural manufacturing plant a day earlier after more than 300 investigators combed through the blast site. 

The blast happened at Accurate Energetic Systems near Bucksnort, located about 50 miles west of Nashville, just before 8 a.m. local time Friday. 

Since then, more than 300 people had conducted a “very delicate, very methodical” search of the scene, Humphreys County Sheriff Chris Davis said at a press conference Saturday. 

“I can tell you that more than 300 people have been through almost every square inch of this facility, and at this time, we’ve recovered no survivors,” Davis said, at times growing emotional. 

Rescuers had to wait for hours to begin their search because of the burning field of debris and risks of secondary explosions at the site southwest of Nashville, authorities said. The area is now secure and there is no longer a risk. 

Davis said he expected that the investigation would span at least days before authorities would know what could have caused the explosion that happened just before 8 a.m. on Friday. He cautioned that there wouldn’t be a “short-term explanation.”

Davis said the explosion Friday resulted in a number of fatalities, which he didn’t specify, and that 18 people were still missing. He referred to them as “souls.” 

The manufacturing plant sits on 1,300 acres in Bucksnort, Tennessee, an unincorporated rural community approximately 60 miles southwest of Nashville. There are eight plant buildings that manufacture, store and research explosives for customers beyond just the military, including aerospace, oil and other commercial demolition industries. 

The company also uses the sprawling campus to test explosives, according to its website, measuring the velocity of explosions as well as their impact on surrounding areas under varying environmental conditions.

“At the height of the response yesterday, there were more than 300 emergency personnel from 18 local, state, and federal agencies on scene collaborating on the ongoing investigation and response,” the Tennessee Emergency Management Agency said Saturday. “This coordinated effort is focused on ensuring public safety, supporting impacted families, and determining the cause of the incident.” 

“We ask Tennesseans to join us in prayer for the families impacted by this tragic incident,” Tennessee Gov. Bill Lee wrote on X on Friday.
