Setting Up and Using Your System

Working in Comfort and Safety

Chapter 134

example, if you are primarily using the keyboard, place it directly in

front of you, not to the side. If your work involves extensive use of a

mouse or other pointing device, place that device directly in front of

your left or right arm. If you are using both a mouse and keyboard,

place them both at the same work surface height and close together.

If a palm rest is used, the height should be ﬂush with the front edge

of the keyboard. Other items, such as your telephone or notepad,

should also be considered.

CAUTION Various aspects of using mice, keyboards and other input devices may

increase your risk of discomfort or injury. Optimize your comfort and

safety by positioning these devices properly.

Your Work Posture

Sitting in one position for long periods can be uncomfortable. To

minimize the potential risk for physical discomfort or injury, it’s

important that you maintain a proper posture.

• Head. When viewing your monitor, your head should not be tilted

more than 15 degrees forward, and do not turn your head toward

either side.

• Back. While sitting at your work surface, make sure your back is

supported by the chair's backrest in an erect position or angled

slightly backwards.

• Arms. Make sure your arms and elbows are relaxed and loose, with

your upper arms perpendicular to the ﬂoor or tilted downward not

more than 15 degrees. Keep your forearms and hands approximately

parallel with the ﬂoor with elbows bent between 70 and 115 degrees.

Keep your elbows close to your sides (less than 20 degrees away from

your body).

• Hands, Wrists, Forearms. Try to keep your hands wrists and

forearms in a relaxed neutral position when using your mouse

keyboard or other input devices. For example, while using your

keyboard and mouse, rest your forearms (ﬂat) on your desktop.

• Legs. Your thighs should be horizontal or angled slightly downward.

Your lower legs should be near a right angle to your thighs. Make

sure there is sufﬁcient room under the work surface for your legs.
