Basic Rules for Workplace Design and Adjustment
Sitting: interlinked workplaces with predefined working height
- The height of the elbows of tall men (95%) in sitting position define in most cases the height of the dominant hand activity, which is at +/- 80 cm. The height of the work surface depends also on the workpiece and/or the tools that are used.
- Leave enough room under the table for the knees of a tall man (95%), at least 67cm high.
Standing: fixed working height to be used by various persons
Sit-Stand: Options to enable adopting varying working postures
A universal solution is a workbench easily adjustable in height between 64 – 130 cm. It can support any needs in both sitting or standing posture, independently of the size of the person nor the type of task.
Working in standing posture:
- Determine the optimal height of the workbench in standing posture for a given operator
- Provide a high work chair and adjust the height, in order that the elbows of the operator remain exactly at the same height as in standing posture.
- A footrest will be needed in all cases to compensate at feet level with an adjustable height between 50 - 65 cm. Ideally, footrests are integrated into the workbench.
