General 4 Working in Comfort Keyboard Slope Document Holder Thigh Clearance ≥6 cm Keyboard Height 64-76 cm • Work Surface Height - Adjust either your seat height, work surface or both, to position the work surface at approximately elbow height. • Work Surface Arrangement - Make sure frequently used equipment is within easy reach. For example, if you are primarily using the keyboard, place it directly in front of you, not to the side. If you are primarily using the mouse, place it in front of your hand or arm. If you are using both a mouse and keyboard, place them both at the same work surface height and close together. If a palm rest is used, the height should be flush with the front edge of the keyboard. Other items, such as your telephone or notepad, also should be considered. • Monitor - Place your monitor so that the top of the screen is at, or slightly below, eye level (up to 15 degrees). • Head - Do not tilt your head forward by more than 15 degrees, and try not to turn your head toward the 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 arm perpendicular to the floor or slightly forward. 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). • 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. English 53
