Abstract: On April 1, 2006, Employee #1 and a coworker were assigned to change out a sump pump located in the Continuous Annealing Line basement. The old sump pump had been removed and the new sump pump was on a cart on top of the grated metal floor. At approximately 2:38 a.m., while walking around the cart, Employee #1 stepped through a hole in the floor grating and his right leg went through the hole into hot water to a point above the knee. The water beneath the floor is approximately 185 degrees Fahrenheit. Employee #1 suffered third-degree burns to the right leg and lesser burns to the right arm where he was splashed by hot water. Employee #1 was hospitalized.
