Follow the steps in our Ergonomic Design checklist to help assess the best solutions for your work benches and workstations and to ensure that your staff minimise workplace health and safety concerns.

Workstation Ergonomic Checklist

1. Correct Work Height

  • An operator’s arms should be below shoulder level
  • Precise tasks:         50mm below elbow
  • Light assembly:     50-100mm below elbow
  • Heavy work:         100-200mm below elbow

2. Properly Adjust Work Equipment to the Task

  • Adjust the workstation:
  • Seat height & angle; footrest height & angle
  • Adjust the work piece and parts containers:
  • Work piece and parts containers in optimal positions (refer to points 3 and 4)

3. Work Piece & Parts Container Layout

  • Optimise container layout to reduce wasted motion and speed up throughput
  • Heavy and/or most used parts should be placed in the closest containers
  • Optimal container layout is within a 400mm radius, as measured from each shoulder

4. Working Area

  • Maximum grab area: 540mm radius, measured 160mm to the left and right from the
  • centreline and front edge of the work top
  • Optimum grab area: 280mm radius, measured 160mm to the left and right from the
  • centreline and front edge of the work top

5. Consider Fields of Vision

  • Operators should view the work piece without turning head or eyes
  • A 15 deg. view angle requires no head or eye movement to grab parts
  • A 35 deg. view angle requires only eye movement to grab parts
  • Viewing distance to a Monitor should be between 350mm and 750mm

6. Match Light Intensity to the Work Task

  • Standard assembly tasks: 500—750 lux
  • Complex tasks (e.g. electrical assembly):    1000—1500 lux
  • Delicate and/or critical work: 1500—2000 lux

7. No Work Above the Heart

  • Keep all work below the heart to enhance blood circulation
  • Reduce static holding during assembly as it increases muscle fatigue
