UPDATE (2:30 p.m. on Thursday, Sept. 7): An investigator for the West Virginia State Fire Marsal’s Office is releasing more details on an incident at a Braxton County sawmill that injured a man.

The victim, a man in his 40s, was working at the lumber yard on an experimental process called Biochar to make a type of charcoal from wood when the accident happened. Officials say during the incident, a deflagration reaction caused the door to blow off the container, striking and injuring the man.

Through the investigation, the WVSFMO learned that it was the deflagration reaction, not an explosion, that caused the incident.

The fire marshal’s office says the man sustained injuries to his upper body from the door as well as some minor burns. According to the WVSFMO, the man was taken by ground unit to a hospital in Pittsburgh, not flown.

However, officials from the West Virginia State Fire Marshal’s office now report that the person did survive and was flown to a hospital in Pittsburgh, Pennsylvania.
