Keyboard
Generally, the more a keyboard is used, the greater the chance of risk or discomfort. This does not mean that people should not use a keyboard extensively; however job design and adjustable equipment and furniture are important considerations for people who use computers for an extended period of time.
Place the keyboard as close to the front edge of the desk as is comfortable. Tilt the keyboard, to suit your level of comfort, or sit it flat which ever feels best. Reference documents should be placed between the keyboard and the screen, or suspended alongside the screen. Do not place documents between the keyboard and the front edge of the desk while using the keyboard, as this increases the reach distance to
the keyboard and may result in excessive bending of the neck to look at documents. Ensure that there is room to put the keyboard to one side when not in use.
