Ergonomics Awareness Training for Supervisors Practice Test

The ideal height for an ergonomic keyboard is at elbow height because this positioning aligns the arms and wrists in a neutral, relaxed position while typing. When the keyboard is at elbow height, it allows for the forearms to be parallel to the ground or slightly declined, which helps in reducing strain on the wrists and shoulders. This ergonomic alignment minimizes the risk of repetitive strain injuries and promotes better posture.

Positioning the keyboard above shoulder level would require the individual to raise their shoulders, leading to tension and fatigue over time. Placing it below knee level would necessitate awkward bending and could contribute to discomfort and strain on the back and legs. Similarly, having the keyboard at eye level would likely result in an unnatural wrist angle, leading to potential injuries. Therefore, situating the keyboard at or just below elbow height is the most beneficial for ergonomic efficiency and health.
