4 Working in Comfort
In addition, there have been reports associating the occurrence of RSI
with the use of computer keyboards, mice, and other input devices.
Also, certain medical conditions, such as rheumatoid arthritis, obesity
and diabetes, may predispose some people to this type of injury.
What can I do to avoid
RSI? Some people who use computers may experience physical discomfort
during their use. This discomfort may be a symptom of a repetitive
strain injury. Properly setting up and using computing equipment can
help to minimize your chances of experiencing this discomfort. Well-
designed and properly adjusted equipment alone may not be sufficient
to eliminate all potential problems. Maintaining good posture and
positioning when working on computers also has a significant bearing
on your comfort.
What if I experience
discomfort? If you are experiencing any discomfort, seek professional medical
advice immediately. Typically, the earlier a problem is diagnosed and
treated, the easier it is to resolve.
Preparing Your Work
Environment When using HP computing equipment, it is important that your work
environment contribute to your comfort and productivity.
Your Chair It's very important that your chair provides a comfortable sitting
position and offers the following features:
• A stable base, such as five legs with casters. Make sure the casters
are designed for the type of floor you have in your workspace,
whether it is bare or carpeted.
• A height- and tilt-adjustment feature. It should be easy to adjust
your chair height from 40 cm to 52 cm (15.5 inches to 20.5 inches)
as measured from the top of the seat pan to the floor. If you are much
taller or shorter than average, you may need a chair that can be
adjusted beyond this range. Adjust your chair so that the work
surface or keyboard tray is at elbow height and your feet are flat on
the floor with your knees slightly bent below your hips. Ideally, the
seat pan should be able to tilt both forward (minimum of 5 degrees)
and backward (minimum of 10 degrees). If the chair has an
adjustable seat pan, inclining the seat slightly forward will transfer
some of the pressure from the spine to the thighs and feet. This will
relieve pressure on your back.
