Employees need to pay special attention to their posture when they are at their workstations. Their feet should be on the floor with their upper legs parallel to the floor. Their back should be in an upright position, not slouched or too stiff. Elbows should be next to their torso, not extended. Shoulders should be back and relaxed and reaching for the keyboard should be avoided.
Monitors also have an impact on ergonomics.
Improperly positioned monitors can cause stress on vertebrae and spinal discs. Position monitors so the first line of text is at eye level. Employees that wear bifocals should position their monitors lower so that they do not have to tilt their neck up to view the screen. Of course, position the monitors so they do not reflect a glare from lights or windows, and make sure that they are approximately 18 to 30 inches away from employees' eyes. Workstation equipment must also be properly adjusted to avoid injury.
