## Narrative

EE was using excavator to assist coworker with changing out a bearing on the head box of the overland conveyor.  Excavator positioned in an awkward position: no access to the step to mount/dismount.  EE attempted to dismount in a safe manner, but caught his right foot in the tracks & twisted his right knee as he stepped to ground (did not fall - twisted out of his shoe).
