EE was welding in a chute. He finished with one welding rod and attempted to throw it onto a shelf close to him. When he threw it, it bounced off a plate and came back into his left shoe burning his leg. Accident occurred on 7/11/13, but EE did not feel need to go to doctor until 7/23/13, which is when we got diagnosis of 3rd degree burns, making it reportable.
