After an introduction on the dose delivery method and the specially needed equipment in proton therapy, operational aspects will be discussed as well as their relation to formal aspects like certification. There will be a focus on the special requirements to reach a high reliability for patient treatments, so on an accurate delivery of the dose at the correct position in the patient using modern techniques like pencil beam scanning. It will be shown that the requirements of the beam are quite different from those in a nuclear physics laboratory. One needs very high requirements on beam intensity and stability to achieve the correct absolute dose and to minimize activation. Since an irradiation treatment cannot be interrupted during the approximately six weeks a patient treatment lasts, it is of utmost importance to have only short and well planned shutdowns for service. The way of operating a medical device requires not only operators, but also the possibility to have a safe machine operation by non accelerator specialists.
