## Narrative

The employee was removing v-belts from an impact crusher.  While removing the v-belts off the sheave, the whole sheave assembly fell off causing the v-belts to pull down weight of the sheave which struck the employee in the face.  Initially this injury was first aid only; then the employee was referred to a dentist for further intervention.
