## Narrative

The employee was drilling in the back with a 4' steel for the purpose of installing ground support. The steel broke near the chuck which caused the machine to extend unexpectedly and start to fall. The employee quickly retreated but his left arm made contact with a split bolt which was standing next to the rib. This caused a laceration which required sutures.
