Creating a Comfortable Working Environment
Under circumstances of poor posture or poor setup, certain recent scientific articles
suggest that injuries may occur. Other articles suggest that there is no cause and
effect. Because the safety of our users is a great concern, it is important to take
these precautions:
•
Be comfortable in your work space.
•
Change your posture frequently.
•
Proceed according to the recommendations in the following table and figure.
Adjust So . . .
Chair Feet are flat on the floor.
Legs are vertical forming a right angle to the floor.
Your weight is off your thighs and they are horizontal. Keep the back
of your knees away from the seat so you do not compress the area
behind them, which could restrict the blood flow.
Your upper body is erect and your lower back is supported with a
backrest.
Keyboard or mouse Your wrists are straight and do not bend more than 15 degrees. They
may be supported when resting but not on sharp edges. Type
comfortably, with no more key pressure than needed to feel the
contact point.
Upper arms are straight down at your sides, elbows are close to your
sides and support your arm weight. Forearms are at a 70 degree to 90
degree angle.
If you use a mouse, rest your hand on the mouse so your wrist is not
on the work surface. Operate the mouse close to your body’s
centerline.
Head Avoid neck strain. Your head should incline downward, but no more
than 15 to 20 degrees.
