In the packing department, a worker stands sideways between the end of a conveyor and pallet. The surface of the conveyor is 40 inches from the floor and the top of the pallet is 6 inches from the floor. As a box moves to the end of the conveyor the worker twists 90E to pick up the box, then twists 180E in the opposite direction and sets the box down on the pallet. Each box is 12 inches on aside and weighs 25 lbs. Assume he moves 5 boxes per minute for an 8 hour shift.
Using the NIOSH lifting equation, calculate RWL and LI. Redesign the task to improve it. What is now the RWL and LI?
