Abstract
A handrail sanitization system incorporates ultraviolet light treatment into long straight sections of the handrail run, most preferably along the hidden return area of the endless loop forming the moving handrail. This treatment area allows for longer exposure times to the UV light and facilitates the treatment of the entire outer surface of the handrail. In some versions, an additional dosage controller is provided.
