Appendix B Safety, Use, and Care Information 111
Change hand positions often to avoid fatigue. Some computer users might develop
discomfort in their hands, wrists, or arms after intensive work without breaks. If you
begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a
qualified health specialist.
Chair
An adjustable chair that provides firm, comfortable support is best. Adjust the height
of the chair so your thighs are horizontal and your feet are flat on the floor. The back of
the chair should support your lower back (lumbar region). Follow the manufacturer’s
instructions for adjusting the backrest to fit your body properly.
You might have to raise your chair so that your forearms and hands are at the proper
angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you
can use a footrest with adjustable height and tilt to make up for any gap between the
floor and your feet. Or you can lower the desktop to eliminate the need for a footrest.
Another option is to use a desk with a keyboard tray that’s lower than the regular work
surface.
