EE was working on a 785 truck at Grape Vine South Surface removing the main pump with another EE and a field person from JP Tech. Pump was almost out, EE moved to the side and was waiting for pump to come out to the ground. When it did, it struck the pry bar EE had been using. When the pump fell to the ground, it hit the pry bar and the bar slammed into EE's lower leg.
