A BP oil refinery in Ohio was investigated for failing to safely handle hazardous materials, resulting in the fatal burns of two employees. As the workers attempted to correct rising liquid levels in the fuel gas mix drum, a flammable vapor cloud formed, ignited and then triggered an explosion in September 2022, causing the deadly burns.
OSHA identified the training deficiencies and failure by BP Products North America to meet OSHA's process safety management procedures. They also determined naphtha, a flammable liquid hydrocarbon mixture, was released when flow control valves were opened in an attempt to regulate an overfill occurring in upstream process equipment. The opened valve allowed the flammable liquid to enter the refinery's fuel gas system.
