An employee in the melt department was getting ready to put a recirculation pump into the pump housing area. He first put the pump in a cabinet to warm it up to avoid thermal shock. It shifted and the cold refractory contacted the hot metal. Molten metal contacted the employee, resulting in third-degree burns between their knee(s) and ankle(s). The employee was wearing some personal protective equipment (PPE) at the time but this was breached by the molten metal.
