Various studies, including those by Harvard University, show that reducing hand contact points counteracts the spread of pathogens. These contact points include surfaces that are regularly touched by different people, such as door handles, light switches and toilet flush buttons or handles. The most hygienic sanitary facility is one where nothing is touched, a so-called 'touch-free toilet'.
High footfall locations
During a visit to the toilet, multiple soiled surfaces are touched, both before and after washing hands. For example, the most recent Dutch National Toilet Research shows that almost 1 in 4, 24%, of all taps are contaminated. Also, the majority of toilet flushes and door handles are dirty.
Especially in buildings that attract many people, such as offices, restaurants and hospitals, it is important to limit the number of washroom contact points as much as possible. This can be done in various ways. The most common is the installation of sensor-controlled doors, flushing, taps and hand dryers.
