Firefighters arrived and attempted to extinguish the large fire when an explosion occurred Friday, Lenoir County Emergency Services said in a press release.
A civilian who was fighting the blaze before firefighters arrived was fatally injured and pronounced dead at the scene, the release said.
Three La Grange Volunteer Fire Department Firefighters were injured in the explosion and taken to hospitals for treatment, the release said. Two of the firefighters were released, and the third was taken to a burn center.
Fire departments worked through the evening to contain the fire and “fully extinguish hot spots,” Lenoir County Emergency Services said Saturday.
The incident remains under investigation.
