As we discuss in Chapter 10, ergonomics is an important element in Job Design and the Work Environment, so it may be a good time to ask “Is My Computer Setup Ergonomically Correct?”. Proper monitor distance, chair height, desk and even mouse placement all make a difference in work performance and stress on the human anatomy.
The Mayo Clinic offers advice in EHS Today (June 1, 2023) on how to set the proper positioning when using a computer in order to avoid some of the health problems associated with seated work, such as neck and back pain and sore wrists and shoulders. The chair height, equipment spacing and desk posture all make a difference.
First, choose a chair that supports your spine. Adjust the height of the chair so that your feet rest flat on the floor. Or use a footrest so your thighs are parallel to the floor. If the chair has armrests, position them so your arms sit gently on the armrests with your elbows close to your body and your shoulders relaxed.
Second, under the desk, make enough room for your legs and feet. Don’t store items under your desk, as that can shrink the amount of available space and make it hard to sit correctly. If the desk is too low and the desk height can’t be changed, put sturdy boards or blocks under the desk legs to raise it. If the desk is too high and can’t be changed, raise your chair.
Third, put your computer keyboard in front of you so your wrists and forearms are in line and your shoulders are relaxed. If you use a mouse connected to a computer, place it within easy reach, on the same surface as your keyboard. While you are typing, using a computer touchpad, or using a mouse or pointer, keep your wrists straight, your upper arms close to your body, and your hands at or slightly below the level of your elbows.
Finally, place the computer monitor straight in front of you, directly behind your keyboard, about an arm’s length away from your face. The monitor should be no closer to you than 20 inches and no further away than 40 inches. The top of the screen should be at or slightly below eye level.
