NORTH CAROLINA (From news reports) -- An "explosion" has been reported at an International Paper manufacturing facility in North Carolina, resulting in one person being briefly hospitalized, state officials said.

It happened just before 4 a.m. Tuesday, May 26, at International Paper in Manson, the Warren County Sheriff's Office said in a May 26 Facebook post. Manson is about a 50-mile drive northeast from downtown Raleigh.

"We can confirm an incident with a boiler in our Mason, N.C., box plant occurred in the early morning hours on Tuesday," International Paper said in a statement. "Team members on site were quickly evacuated. Two people were treated on site for minor injuries."

The Office of State Fire Marshall is leading an investigation into the cause of the "blast," with assistance from the N.C. State Bureau of Investigation.

"We are coordinating with N.C. Emergency Management assets to determine the stability of the structure and address other safety concerns before a scene examination can be made," the Office of State Fire Marshall said. "There was one subject who was transported to the hospital with minor injuries and has since been released."
