may need to be tilted, for example, for tasks involving delicate or precise manipulation.
Tasks where the hands make a narrow range of movements and can rest on the work surface should be performed at, or just above, elbow height. A sloping surface may reduce the amount of neck flexion required to perform desk-based tasks, such as drafting.
Light manipulative tasks or tasks involving the use of a keyboard should be performed at just below elbow height.
Tasks incorporating a range of arm movements using the shoulder should be performed at between hip and shoulder height, for example taking items from a stack and placing them on
a conveyor.
Tasks requiring considerable muscular effort or use of the body for leverage, for example, drilling at a workbench, should be performed at hip height and no higher.
Where possible, place items used in manual tasks so they are:
    * in front of the worker
    * between waist and shoulder height
    * close to the midline of workers and orientated towards the worker
    * on the worker's preferred side
    * positioned within comfortable reaching distance
    * positioned to avoid double handling and to avoid moving loads manually over long distances.
Displays and controls should be positioned to encourage comfortable head and neck postures, comfortable hand and arm reach and efficient use. You should:
    * place frequently used displays and controls, including keyboards and other input devices, directly in front of the worker
    * position controls at comfortable elbow height
    * select electronic or foot controls rather than hand controls if high force is required
    * place pedals so that workers can operate them from a comfortable seated position.

Working position

Workers should not remain in a seated, standing or otherwise static posture for prolonged periods. Design the workstation to provide opportunities for workers performing seated or standing tasks to vary their postures and movements
For seated tasks, seating should have the following features:
    * adjustable seat height and angle
    * a contoured backrest with a lumbar curve except those where the backrest would interfere with the actions to be performed
    * a swivel action to prevent the worker from twisting to reach workstation components
    * rounded seat edges
    * a five-point base with casters to allow movement on carpet, and gliders fitted to the base for low-resistance flooring, where access to work items located beyond normal reach is required
    * a footrest or foot ring fitted on drafting or higher chairs to support the feet.
A seated work position is best for:
    * work that requires fine manipulation, accurate control or placement of small objects
    * close visual work that requires prolonged attention
    * work that involves operating a foot pedal.
