## Narrative

EE was inside cab of machine scaling when rock from the mine roof fell & struck the cab of the scaler. The rock that hit the equipment jolted the worker inside the cab. 1 or 2 small rock pieces had fallen in the area just before the last rock fell. The engine on the scaler turned off after the cab was struck so the worker exited the cab through rear window to flee the work area
