## Narrative

The driller was in the process of removing the DTH hammer from the drill steel.  He applied a locking wrench to the hammer, and he stepped out of the cab to connect the drill steel to the rotation head.  As the two parts connected, the wrench turned and struck the driller's foot, fracturing bone in his foot.
