A chemical processing worker pushes a heavily loaded drum trolley across a rough textured floor surface. The rough floor increases the required push force from 40 lbs on smooth surfaces to 75 lbs. Which Engineering intervention most directly addresses this push force problem?

Question

Answer

Training the worker to lean their full body weight into the trolley and use momentum to overcome resistance of the rough floor.

Answer

Rotating the worker between trolley pushing and a lighter administrative role every 45 minutes throughout the entire working shift.

Answer
