Setting Up a Healthy Work Environment A-5
!
Adjust the keyboard height so that your elbows are near your body
and your forearms are parallel to the floor, with your forearms resting
on either armrests or forearm supports, in the manner described
previously. If you do not have armrests or forearm supports, your
upper arms should hang comfortably at your sides.
!
Adjust the keyboard slope so that your wrists are straight while you
are typing.
!
Type with your hands and wrists floating above the keyboard. Use a
wrist pad only to rest your wrists between typing. Avoid resting your
wrists on sharp edges.
!
Type with your wrists straight. Instead of twisting your wrists
sideways to press hard-to-reach keys, move your whole arm. Keep
from bending your wrists, hands, or fingers sideways.
!
Press the keys gently; do not bang them. Keep your shoulders, arms,
hands, and fingers relaxed.
Adjust Your Screen or Monitor
Correct placement and adjustment of the screen or external monitor can
reduce eye, shoulder, and neck fatigue. Check the following when you
position the screen or external monitor.
!
Adjust the height of your screen or external monitor so that the top of
the screen is at or slightly below eye level. Your eyes should look
slightly downward when viewing the middle of the screen or external
monitor.
!
Position your screen or external monitor no closer than 12 inches and
no further away than 28 inches from your eyes. The optimal distance
is between 14 and 18 inches.
!
Rest your eyes periodically by focusing on an object at least 20 feet
away. Blink often.
