Abstract: An apparatus for disinfecting a user's hands has a spray chamber or an open spray zone with an opening for a user to insert his or her hands into the chamber. A supply of a disinfecting solution is provided, and preferably comprises a storage tank with a concentrated solution. This solution is mixed with an incoming freshwater supply, e.g. in a venturi valve, and supplied through spray nozzles into the chamber. A sensor detects the presence of a user's hands and automatically operates the spray nozzles for a predetermined time. The apparatus can also include a fan with its own timer, to provide a supply of drying air. Thus, a user can insert his or her hands, disinfect them with the disinfecting solution, remove the hands and dry them, without requiring any manual operation.
