ABSTRACT:
A self-monitoring hand-sanitizing station having a basin capable of holding an antiseptic solution to be situated near the entrance to a food handling area. A first proximity detector determines when an individual is approaching both the basin and the entrance. The basin contains a first moisture-proof switch and a second moisture-proof switch the activation of which switches must be done simultaneously; these switches are so situated that a user cannot accomplish such simultaneous activation with a single hand. A second proximity detector determines when an individual has passed beyond the basin toward the entrance. And a logic unit receives electrical inputs from the first proximity detector, the second proximity detector, the first moisture-proof switch, and the second moisture-proof switch to determine when an individual has approached both the basin and the entrance but passed beyond the basin toward the entrance without having simultaneously activated the first moisture-proof switch and the second moisture-proof switch. When such a determination is made, an output signal is generated by the logic unit, which output signal activates an alarm.
