At about 11:00 p.m. on March 12, 2025, an employee entered a reduction furnace tower to remove a thermowell tube that had broken and became lodged in the furnace. While he was shifting the thermowell, the metal hit the wall of the furnace, causing a "scab" of iron ore (3 feet x 1 foot x 8 inches) to fall from the furnace's interior surface. It struck the employee's head. The employee lost consciousness and was hospitalized.
