Investigating Clinical Hand Hygiene Sink Splash Radius

Summary

This study will look at how water splashes from sinks during handwashing and how far those droplets can travel. We will test different sink and faucet designs to see which ones create the most or least splash. To do this, we will use a safe glowing substance on hands and in the sink drain so we can see where the water goes under a black light.

We will ask you to wash their hands several times at different sinks while we take photos of the splash patterns. Afterwards, we will ask about your experience using each sink and faucet.

The purpose of this study is to find out which sink and faucet designs are safer and easier to use. The results will help hospitals and clinics choose better sinks to reduce the spread of germs and improve patient safety.
