## Narrative

EE was using a cordless impact to undo bolts on the CR1 flywheel. EE positioned a hand behind the sheave, between the crusher frame and the nut to hold the nut when it broke free. When the bolt broke loose, the nut followed the threads, moving backward and pinching the employees finger between the nut and the frame. EE was brought to get X-rays where a fracture was discovered.
