## Narrative

EE was installing the double winch bracket onto the boom tip of the digger derrick. He was pushing the bracket down so it could swing over the boom tip. When the bracket went EE fell forward causing his left ankle to twist resulting in a fracture to the left fibula. The tight fitting bracket and the terrain were contributing factors.
