Why is a surface of proper height necessary while working standing?
Answer and explanation
Correct answer: To reduce the need to bend and fatigue
While working standing, the work surface should suit the worker and the task. A proper height reduces repeated bending and unnecessary shoulder elevation, thereby reducing fatigue in the back, neck and legs. A surface that is too low increases bending, whereas one that is too high can strain the shoulders and arms. Exam tip: In ergonomics, connect proper work height with good posture, comfort and reduced fatigue.
