Page 152: Setting Up A Healthy Work Environment
Setting Up a Healthy Work Environment WARNING Prolonged or improper use of a computer workstation may pose a risk of serious injury. To reduce your risk of injury, set up and use your computer in the manner described in this appendix. Contact a doctor if you experience pain, tenderness, swelling, burning, cramping, stiffness, throbbing, weak- ness, soreness, tingling and/or numbness in the hands,...
Page 153 Although some studies have shown an association between increasing hours of keyboard use and the development of some musculoskeletal disorders, it is still unclear whether working at a computer causes such disorders. Some doctors believe that using the keyboard and mouse may aggravate existing musculoskeletal disorders.
Page 154: Arrange Your Equipment
ARRANGE YOUR EQUIPMENT Arrange your equipment so that you can work in a natural and relaxed position. Place items that you use frequently within easy reach. Adjust your workstation setup to the proper height (as described in this appendix) by lowering the table or stand that holds your computer equipment or raising the seat height of your chair.
Page 155: Adjust Your Chair
ADJUST YOUR CHAIR Your chair should be adjustable and stable. Vary your posture throughout the day. Check the following: Keep your body in a relaxed yet upright position. The backrest of your chair should support the inward curve of your back. Use the entire seat and backrest to support your body.
Page 156 Your seat depth should allow your lower back to comfortably contact the backrest. Make sure that the backs of your lower legs do not press against the front of the chair. Extend your lower legs slightly so that the angle between your thighs and lower legs is 90°...
Page 157: Adjust Your Input Devices
ADJUST YOUR INPUT DEVICES Follow these points in positioning your keyboard and mouse. Position your keyboard directly in front of you. Avoid reaching when using your keyboard or mouse. If you use a mouse, position it at the same height as the keyboard and next to the keyboard.
Page 158 Type with your hands and wrists floating above the keyboard. Use a wrist pad only to rest your wrists between typing. Avoid resting your wrists on sharp edges. Type with your wrists straight. Instead of twisting your wrists sideways to press hard-to-reach keys, move your whole arm.
Page 159: Adjust Your Monitor
ADJUST YOUR MONITOR Correct placement and adjustment of the monitor can reduce eye, shoulder, and neck fatigue. Check the following when you position the monitor. Adjust the monitor height so that the top of the screen is at or slightly below eye level. Your eyes should look slightly downward when viewing the middle of the screen.
Page 160 Rest your eyes periodically by focusing on an object at least 20 feet away. Blink often. Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen.
Page 161: Vary Your Workday
VARY YOUR WORKDAY If you use your computer for prolonged periods, follow these instructions. Vary your tasks throughout the day. Take frequent short breaks that involve walking, standing, and stretching. During these breaks, stretch muscles and joints that were in one position for an extended period of time.
Page 162: Preexisting Conditions And Psychosocial Factors
Use a timer or reminder software to remind you to take breaks. To enhance blood circulation, alter your sitting posture periodically and keep your hands and wrists warm. PREEXISTING CONDITIONS AND PSYCHOSOCIAL FACTORS Preexisting conditions that may cause or make some people more susceptible to musculoskeletal disorders include the following: hereditary factors, vascular disorders, obesity, nutritional deficiencies (e.g., Vitamin B deficiency),...
