Setting Up And Using Your Workstation Working in Comfort and Safety WARNING • Work Surface Arrangement. Arrange the elements of your HP workstation system (monitor, document holder, keyboard, mouse and other input devices, and headphones and speakers) to meet your personal requirements. For example: - If you primarily use the keyboard, place it directly in front of you, not to the side. - If your work involves extensive use of a mouse or other pointing device, place that device directly in front of your left or right arm. - If you are using both a mouse and keyboard, place them both at the same work surface height and close together. - If you use a palm rest, the height should be flush with the front edge of the keyboard. - Also consider where you place other items, such as your telephone or notepad. Various aspects of using a mouse, keyboard, and other devices may increase your risk of discomfort or injury. Optimize your comfort and safety by positioning these devices properly. Working Posture Sitting in one position for long periods can be uncomfortable. To minimize the potential risk for physical discomfort or injury, it is important that you maintain a proper posture. • Head. When viewing your monitor, your head should not be tilted more than 15 degrees forward. Do not turn your head to either side. • 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. Make sure your arms and elbows are relaxed and loose, with your upper arms perpendicular to the floor or tilted downward not more than 15 degrees. Keep your forearms and hands approximately parallel with the floor with elbows bent between 70 and 115 degrees. Keep your elbows close to your sides (less than 20 degrees away from your body). 26 Chapter 1
