|Checklist for an ergonomic workplace:|
|Frequent headaches, backache, a stiff neck, eyestrain - is this something you associate with your workplace? It could well that a few adjustments or a new chair are all you need for more comfort at work! We at Carl Zeiss have compiled a checklist to help you examine your own workplace: |
|Tables for computer workstations (TCW):|
|Lateral leg room for TCW with height adjustment |
|Lateral leg room for TCW without height adjustment|
650 to 690 mm
|Range of adjustment for TCW with height adjustment |
680 to 760 mm
|Table height for TCW without height adjustment |
|Height of keyboard (height of keyboard itself approx. 30 mm) from floor should not exceed |
|Minimum table width |
|Optimum table depth |
|Table surface should reflect as little light as possible |
|Height of seat for chairs with height adjustment |
420 to 530 mm
|Range of adjustment for chair backs from seat height |
170 to 230 mm
|Chair should have a minimum of 5 casters |
|Optimum seat height: |
With the upper arm hanging loosely, the lower arm should be horizontal at the same level as the plane of work
The optimum sitting posture:
Thighs should be positioned horizontally on the chair surface; if this is not possible by a chair or table with height adjustment, a foot rest with the dimensions 450 x 350 mm should be used
|Screen, keyboard, copy holder |
|Distances from screen, keyboard and copy holder |
450 to 600 mm
|Distance between keyboard and front edge of table |
50 to 100 mm
|Height of keyboard (center), max. tilt 15° |
max. 30 mm
|Positioning of screen/illumination |
Screens should be positioned at right angles to windows.
They should not be installed in such a way that you are looking out of a window or at a bright surface.
Reflections from windows, lights or bright surfaces on the screen should be avoided to the greatest possible extent. Screen filters, curtains or special lighting may provide a suitable remedy here.
Fluorescent tube lighting should be installed so that it runs parallel to the direction in which you are looking when using your computer.
Separate lighting at your computer workstation is not recommended.
