Witnesses compared the blast to a bomb going off, and one said windows rattled from the force.

One person is dead in central Kentucky after a gas line ruptured and produced a fireball that could be seen around the region early Thursday.

The 30-inch gas line in Lincoln County breached around 150 feet from a mobile home park around 1:40 a.m., Don Gilliam, director of Lincoln County Emergency Management, said early Thursday.

One person was killed, three were transported to hospitals with injuries and at least six mobile homes were affected by the fire, Gilliam said just before 4:30 a.m. Three mobile homes were still burning, he said.

"We still have an active scene," Gilliam said, but added that the fire at the breach site was out.

He said when he arrived, flames were around 300 feet in the air. The emergency management agency told residents to steer clear from the Hustonville area.

Video posted to social media showed what appeared to be a large fireball and flames. Witnesses told NBC affiliate WLEX of Lexington that they heard a loud sound and saw a ball of fire.

"It felt like an atomic bomb went off," Jerry Sinkhorn told the station.

"And I knew what it was — it was a gas line," he said.

Sue Routin told WLEX that she was woken up by “a big roar and fire going all the way up in the sky as far as you could see.”

She said her windows shook and the ground seemed to move, which prompted her to get in her vehicle and leave.

 

Gilliam said the situation does not involve a hazardous material.

He said that when the gas line erupted it caught fire but "that burned off," and the biggest problem initially was heat and smoke.

Lincoln County is south of Lexington.

Officials urged people to stay away and said that even though the gas line was shut, there were other fires from the incident early Thursday.

“It was impressive, it’s tragic, we hope it doesn’t get worse,” Gilliam said.
