## Narrative

The miner was working on the removal of the Primary Crusher South Side Sheave. He needed to remove one of the two bolts on the back side using a striking wrench and a 4lb hammer. He put the wrench on the nut using his left hand and started swinging the 4lb hammer from the bottom up.  He hit the wrench a few times before it impacted his left hand index finger.
