A worker is lifting a box from a starting vertical height of 34 inches and placing the box at a vertical destination above the shoulders, approximately 65 inches high. The box is held reasonably close to his body (use 10 inches). The shape of the box is good, but there are no cut-outs or handles for the hands, so the hand-to-container coupling classification is fair. The worker is performing the lift with no asymmetry. The worker handles approximately 4 boxes per minute and is lifting these 50-pound boxes throughout his eight- hour shift.
With these conditions, use this NIOSH Lifting Analysis Worksheet (PDF)Preview the document to calculate the recommended weight limit (RWL) at the origin and at the destination. Then, calculate the lifting index (LI) at the origin and at the destination.

In a document, answer these questions and recommendations:

What is the recommended weight limit (RWL) at the origin and at the destination?
What is the lifting index (LI) at the origin and at the destination?
What do the calculated LI values say about the potential hazard of the task?
Make some recommendations on how to reduce the potential hazard.
How would these recommended modifications reduce the multiplier values on the worksheet? (How do your recommendations compare to the original task?)
What would the revised LI and RWL values be with these modification
