The ergonomic checklist below is intended to provide suggestions for improving your personal comfort and productivity.
Individuals must determine how best to apply the suggestions to their work environments.
- Push your hips as far back as they can go in the chair.
- Adjust the seat height so your feet are flat on the floor and your knees equal to, or slightly lower than, your hips.
- Adjust the back of the chair to a 100°-110° reclined angle. Make sure your upper and lower back are supported. Use inflatable cushions or small pillows if necessary. If you have an active back mechanism on your chair, use it to make frequent position changes.
- Adjust the armrests (if fitted) so that your shoulders are relaxed. If your armrests are in the way, remove them.
If you have an articulating keyboard tray, it should accommodate the mouse, enable leg clearance, and have an adjustable height and tilt mechanism. The tray should not push you too far away from other work materials, such as your telephone.
- Pull up close to your keyboard.
- Position the keyboard directly in front of your body.
- Determine what section of the keyboard you use most frequently, and readjust the keyboard so that section is centred with your body.
- Adjust the keyboard height so that your shoulders are relaxed, your elbows are in a slightly open position (100° to 110°), and your wrists and hands are straight.
- The tilt of your keyboard is dependent upon your sitting position. Use the keyboard tray mechanism, or keyboard feet, to adjust the tilt. If you sit in a forward or upright position, try tilting your keyboard away from you at a negative angle. If you are reclined, a slight positive tilt will help maintain a straight wrist position.
- Wristrests can help to maintain neutral postures and pad hard surfaces. However, the wristrest should only be used to rest the palms of the hands between keystrokes. Resting on the wristrest while typing is not recommended. Avoid using excessively wide wristrests, or wristrests that are higher than the space bar of your keyboard.
- Place the pointer as close as possible to the keyboard. Placing it on a slightly inclined surface, or using it on a mousebridge placed over the 10-keypad, can help to bring it closer.
You may need to adjust your workstation height, the height of your chair, or use a seat cushion to get in a comfortable position. Remember to use a footrest if your feet dangle.
Monitor, Documents, and Telephone
Incorrect positioning of the screen and documents can result in awkward postures. Adjust the monitor and documents so that your neck is in a neutral, relaxed position.
- Center the monitor directly in front of you, above your keyboard.
- Position the top of the monitor approximately 2-3” above seated eye level. (If you wear bifocals, lower the monitor to a comfortable reading level.)
- Sit at least an arm's length away from the screen and then adjust the distance for your vision.
- Reduce glare by careful positioning of the screen.
- Place screen at right angles to windows
- Adjust curtains or blinds as needed
- Adjust the vertical screen angle and screen controls to minimize glare from overhead lights
- Other techniques to reduce glare include use of optical glass glare filters, light filters, or secondary task lights
- Position documents directly in front of you, between the monitor and the keyboard, using an in-line copy stand. If there is insufficient space, place documents on a document holder positioned adjacent to the monitor.
- Place your telephone within easy reach. Telephone stands or arms can help.
- Use headsets and speaker phone to eliminate cradling the handset.
Pauses and Breaks
Once you have correctly set up your computer workstation use good work habits. No matter how perfect the environment, prolonged, static postures will inhibit blood circulation and take a toll on your body.
- Stretch for a minute every 20-30 minutes. Always try to get away from your computer during lunch breaks.
- Avoid eye fatigue by resting and refocusing your eyes every 20-30 minutes. Look away from the monitor and focus on something in the distance.
- Use correct posture when working.
