## Narrative

After the employee moved the tripper on 20 conveyor from tank A11 to tank A2, the tripper started rolling back to the east because the #20 conv belt hit the handrail and catwalk crosswalk that was still in place west of tank A1.  The contact of the conveyor with the crosswalk forced the tripper to roll back to the east and hit the employee that was on the A row side of the tripper
