Abstract
Methods and systems are provided for verifying hygienic hand cleaning including a wash basin, having a contaminant sensor positioned in proximity to a drain of the wash basin, to measure a level of contamination of rinse fluid leaving the wash basin; and a processor and associated memory having instructions that when executed by the processor implement: receiving a signal from the contaminant sensor indicative of the level of contamination; and responsively, determining the level of contamination and comparing the level of contamination with a contamination threshold to determine a hand washing status.

A hand washing system, comprising:
- a wash basin, having a contaminant sensor positioned in proximity to a drain of the wash basin, wherein the contaminant sensor measures a level of contamination of rinse fluid leaving the wash basin;
- a processor and associated memory having instructions that when executed by the processor implement:
- receiving a signal from the contaminant sensor indicative of the level of contamination;
- and
- responsively, determining the level of contamination and comparing the level of contamination with a contamination threshold to determine a hand washing status.
A method for verifying hygienic hand cleaning comprising:
- receiving a signal from a contaminant sensor positioned in proximity to a drain of a wash basin, so as to measure a level of contamination of rinse fluid leaving the wash basin;
- and
- responsively, determining the level of contamination and comparing the level of contamination with a contamination threshold to determine a hand washing status.
