3 Working in Comfort
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.
• A curved seat edge. The front of the seat should be curved and finished
in a “waterfall” edge.
• An adjustable back support in both height and forward and
backward tilt. It is important that the backrest correctly supports the
lower part, or lumbar curve, of the back.
• A freely rotating swivel so you can move easily from side-to-side.
• Fully adjustable and padded armrests. The chair arms should not
interfere with adjusting the chair or moving it close to your work surface.
