It takes time to effectively clean hands and it is too easy for people to do a quick rinse and move on. Staff need something to slow them down and give hand washing the time and attention it needs.
Sanitimer is a 30 second timer that is connected to the end of the tap. When water is flowing it will time down from 30 seconds to 0, and then beeps. It’s not rocket science, but it is effective in getting staff to focus on hand washing.
