Police Chief Kevin Norris said no one else was injured in the explosion at the Asphalt Express plant in Ardmore, about 90 miles south of Oklahoma City.
“The ID of the deceased is still unknown, but I have been able to confirm that there was one fatality,” Norris told KXII-TV.
“As of right now we confirmed there were no injuries. No one was transported from the scene to the hospital with injuries,” said Norris, who did not immediately return a phone call from The Associated Press.
Phone calls to the company by the AP rang unanswered on Friday and neither the fire department nor emergency services immediately replied to messages seeking comment.
According to its website, Asphalt Express provides transportation, storage and sales of bulk liquids such as asphalt and various types of oil at the Ardmore plant.
