In the packing department, a worker stands sideways between the end of a conveyor and a pallet. The surface of the conveyor is 40 in from the floor, and the top of the pallet is 6 in from the floor. As a box moves to the end of the conveyor, the worker twists 90 degrees to pick up the box, then twists 180 degrees in the opposite direction and sets the box down on the pallet. Each box is 12 in on a side and weighs 25 lbs. Assume the worker moves five boxes per minute for an 8 hr shift and a horizontal distance of 12 in. Using the NIOSH lifting equation, calculate RWL and LI. Redesign the task to improve it. Given your redesign, what are the RWL and LI now?
