Setting Up and Using Your Workstation Working in Comfort and Safety • Hands, Wrists, Forearms. Try to keep your hands, wrists, and forearms in a relaxed neutral position when using your mouse keyboard or other input devices. For example, while using your keyboard and mouse, rest your forearms on your desktop. • Legs. Your thighs should be horizontal or angled slightly downward. Your lower legs should be near a right angle to your thighs. Make sure there is sufficient room under the work surface for your legs. • Feet. If after adjusting your chair you cannot rest your feet comfortably on the floor, use a footrest, preferably one that can be adjusted in height and angle. Additional Ergonomic Issues • Look away from the screen from time to time to help reduce eyestrain. Focus on distant objects briefly, and blink periodically to lubricate your eyes. Have your eyes checked on a regular basis and ensure your eyeglass prescription is suitable for working on a computer monitor. • Remember to occasionally shift position and move your body. Keeping your body in one position for long periods is unnatural and stressful. When prolonged work is required, take frequent short breaks. As a rule of thumb, a five or ten minute break every hour is a good idea. Short frequent breaks are more beneficial than longer less frequent breaks. People who work for long periods of time without a break may be more prone to ergonomic injury. • Changing tasks frequently helps prevent muscle stiffness. Alternate between keyboarding, reading, writing, filing, and moving around in your work environment to help you maintain a relaxed posture. Occasionally stretch the muscles in your hands, arms, shoulders, neck and back. You should stretch at least as often as you take brief task breaks - once every hour. • Discomfort may be alleviated by using alternative ergonomic designs and accessories such as ergonomically personalized chairs, palm rests, keyboard trays, alternative input devices, prescription eyeglasses, and anti-glare screens.
