Sitting at your computer

Avoiding discomfort and injury from repetitive strain

Position your chair so the keyboard is at or slightly below the level of your
■
elbow. This position lets your shoulders relax while you type.
Adjust the chair height, adjust the forward tilt of the seat, or use a footrest
■
to distribute your weight evenly on the chair and relieve pressure on the
back of your thighs.
Adjust the back of the chair so it supports the lower curve of your spine.
■
You can use a pillow or cushion to provide extra back support.
Set up the monitor so the top is no higher than eye level, the monitor
■
controls are within reach, and the screen is tilted to be perpendicular to
your line of sight.
Place your keyboard and mouse at a comfortable distance. You should be
■
able to reach them without stretching.
Set paper holders at the same height and distance as the monitor.
■
Avoid bending, arching, or angling your wrists. Make sure that they are in
■
a relaxed position when you type.
Do not slouch forward or lean far back. Sit with your back straight so your
■
knees, hips, and elbows form right angles when you work.
Take breaks to stand and stretch your legs.
■
Avoid twisting your torso or neck.
■
Vary your activities to avoid excessive repetition.
■
Take breaks to change your position, stretch your muscles, and relieve your
■
eyes.
Find ways to break up the work day, and schedule a variety of tasks.

Working safely
