All items that are touched by the hands need to be
organized. In many cases workers themselves organize
these items at the workstation, but often they do not.
If controls are not easy to see or reach, operators
tend to use them by relying on habits and guesswork.
This can cause mistakes.
Time and effort are saved by placing controls within
easy reach.Controls placed too high cause shoulder
pain, and controls placed too low cause back pain. It is
important to locate them in a place that is easy to reach
from a normal working posture.
