## Narrative

While changing the wear segments on the -3 loader, EE removed the retaining nuts. EE began driving the bolts out from the top-down using a hammer. After striking one of the bolts the hammer contacted the edge of a loose nut that was resting adjacent to the bolt hole. The impact caused the nut to become airborne and strike EE in the mouth, resulting in an injury to EE tooth.
