Ross Townshend, an ergonomics expert for Bosch Rexroth, has written an insightful article discussing easy ideas on how to fully implement an ergonomic solution in any workplace.
In Part 1 we looked at Body and Working Height, Work Area, and Reach Zones. We’ll finish up ideas 4-7 here in Part 2.
4: Parts presentation
The presentation of parts to the operator is essential in minimizing physical exertion and unnecessary movements that would cause repetitive stress injury. The key issues that need addressing are:
- Frequently used grab containers should be placed at short distances
- Heavy parts should be stored within easy reach in lower containers
- Where possible use a slide rail or roller conveyor to minimize employee exertion
5: Range of vision
Each head turn or change in line of sight, results in lost time and decreases productivity. For the optimal workstation design, it is important to address every detail, including head and eye movement. Key vision issues for workstation planning are:
- Avoid unnecessary eye and head movements
- Vision distances should be as identical as possible to eliminate refocusing
- Avoid fastening locations not visible to the operator
The correct light, adapted to the activity of the workstation, is a basic prerequisite for high efficiency and quality. It’s therefore important to:
- Avoid strong lighting contrasts
- Avoid glare and reflection
- Ensure all workstations are free from shadows, flickering and glare
7: Adjustment of work equipment
To maintain performance levels and promote productivity, the correct adjustment of a table, chair, footrest and position of tools and material shuttles must be adjustable. easily achieved.
The correct sitting posture is vital with worker’s calves forming a 90-degree angle with appropriate lumbar support.
As Townshend points out, ergonomics starts with the design of the workplace, not hap-hazard adjustment of equipment after the fact – which will always be a compromise.
