Preparing Your Work Environment
Your Work Posture
Sitting in one position for long periods can be uncomfortable. To minimize the
potential for physical discomfort or injury, it's important that you maintain proper
posture.
• 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 - Your arms should be relaxed and loose, elbows close to your sides, with
forearms and hands approximately parallel to the floor.
• Wrists - Your wrists should be as straight as possible while using the keyboard,
mouse or trackball. They should not be bent sideways, or more than 10 degrees up
or down.
•
Legs
- Your thighs should be horizontal or angled slightly downward. Your lower
legs should be near a right angle to your thighs. Your feet should rest flat on the
floor. If necessary, use a footrest, but double check that you have your seat height
adjusted correctly before getting a footrest.
• Head - Your head should be upright or tilted slightly forward. Avoid working with
your head or trunk twisted.
• Overall - Change your position frequently and take regular breaks to avoid fatigue.
