## Narrative

EE was assigned to calibrate the B Ramsey belt scale load cell. The load cell includes a pivot arm which fluctuates up and down. As the arm is displaced, a signal is transmitted to a meter where the weight of the waste coal is determined. The arm is manually lifted to relieve any tension. EE improperly lifted the pivot arm while using only his right arm and improper body position.
