A 36-page federal report detailing safety concerns and citations issued for the Delek refinery in East Texas, where an explosion in the company’s Tyler plant killed one worker and injured others, has been released. In its report, The Occupational Safety and Health Administration lists safety violations at the Delek Refining Ltd plant from earlier this year that include failing to ensure valves were properly configured and an inability to show structures followed blast resistance guidelines. The report stated that the employers could not document that the FCCU control room and similarly constructed and operated structures adhered to current industry guidelines in terms of blast resistance in the event of a vapor cloud explosion from flammable hydrocarbon chemical release. Federal regulators also fined Delek for not ensuring that valves were properly configured, leaving rotating shafts unguarded and storing unlabeled containers of hazardous materials on site. Workers also didn’t wear proper protective clothing when working with hot oil. Delek failed to add vehicle barriers to prevent accidents at the plant, didn’t provide written emergency procedures in the case of an accidental flare system shutoff and had no classification system to prioritize piping inspections based failure consequences.
