Daan, I agree with the other responses submitted so far. We wear wrist straps (metal watch-band type rather than fabric)and dissipative smocks and work on conductive workbench surfaces. The straps and workbenches linked and are constantly, electronically monitored and sound off if there is a circuit interrupt. We do not employ conductive shoes, floors, etc. as the wrist strap and smock together provide good protection seated or standing. In my opinion, you could save a lot of money and worry by implementing the more reliable wrist straps and forgetting about the shoes. R. G.

Our factory relies on grounding through the (conductive) chairs, ESD-shoes, conductive floor and ESD-workbenches, but the chairs are tested only once per year, which is obviously less frequent then one would test wrist wraps. Is the customers concern justified, and should we introduce wrist wraps ?
