## Narrative

Employee was cleaning the inside of a Komatsu 785 haul truck bed using a hose and ball valve nozzle opened about half way. This wasn't enough pressure to clean out the bed, so EE opened the ball valve to full open causing the water pressure to increase. This increased the force behind the nozzle causing the hose assembly to lift striking and leaving lacerations under EE's chin.
