On May 11, 2023, at 8:15 PM, an employee was unloading a railcar. The car had been steamed and the top was vented. The employee connected the unload hose to the bottom of the car and when the railcar valve was opened to begin the unload process, pressure from the unload piping surged back into the railcar. This caused 200-degree F oil to spill out of the top of the railcar, contacting the employee.
