• Wo rk Surface Height - Your work surface should be height adjustable.
To ensure that your work surface is at the correct height, first adjust the
height of your chair so that your feet are firmly on the floor. Then adjust
the work surface height until your forearms are parallel with this and
other input devices.
• Chair - Your chair should provide a comfortable sitting position
including features such as a height and tilt adjustment, curved seat
edge, a stable base (for example, five legs and castors, adjustable back
support, a freely rotating swivel and fully adjustable padded arm rests).
• Monito r - Place your monitor so that the top of the screen is at, or
slightly below, eye level (up to 15 degrees).
• Wo rk Surface Arrangement - Make sure that all elements of your HP
e-Vectra system for example, monitor, document holder, keyboard,
mice and other input devices, and headphones and speakers- are
optimally arranged and adjusted to meet your personal requirements.
For 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.
• A rms - 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).
