OSHA has concluded that an open-flame heater on the floor of a rig likely sparked the fire that killed three natural gas drillers and seriously injured two others in a December 2014 drilling rig fire in Coalgate, Oklahoma. Prior to this fatal accident, OSHA had already cited the employer (Dan D Drilling Corp.) for allowing the use of an open flame heater on the premises back in June 2013. Kelsey Bellah, 27, and Gary Keenan, 26, died at the scene. Mark Pittman Jr., 26, survived the accident but died from his injuries in the hospital 16 days later. Two others received severe burns upon attempting to assist their co-workers. Proposed penalties total $221,200.
