I need advise how to go about meeting 100% compliance in wrist strap testing. It is stated in our procedure that all employee working on the shopfloor must have thier wrist strap tested daily. We have 3 wrist strap stations place at different location. The operator would test their wrist strap when entering the shopfloor which have no barricade, more like an open field which we call it 'blue zone'. I thought of placing the wrist strap station at each entry door but I was caution that it would cause traffic. There may be a way in automation but I believe it will be very costly. Any cheap and effective idea?
