## Narrative

EE was helping change hammers in a hammer-mill when a hammer got caught and caused the rotor to change directions.  It spun backwards and caught the pry bar the EE was holding onto, causing it to swing and strike him in the lower chin area.  This action resulted in many teeth being fractured and three stitches in the lower jaw.
