## Narrative

The injured EE and coworkers were replacing the motor on a vertical pump. The pump was locked out and a backflow preventer was between the pump and the plant. Using a wrench to adjust the impeller, it began to spin jerking the wrench from coworker's hand & striking the injured EE's wrist. The backflow preventer leaked back and back stop failed allowing it to rotate backwards.
