conflict potential by separating various groups of patients.13 Both measures led to a reduction in the number of fixations in this wing. Furthermore, the approach taken by Diez prison with regard to possible risks of injury and the preservation of human dignity in prisons is for instance regarded as being exemplary: Fixation is carried out using a belt system on a hospital bed that is located in the prison infirmary. This ensures that medical care of the persons who have been fixed is guaranteed.14 3.2 Internal differentiation in prisons The individual departments in Fuhlsbüttel prison in Hamburg correspond to steps built on top of one another, and these differ amongst other things in terms of cell size, furniture or out-of-cell times. The inmates themselves can contribute to their being transferred to a higher step by keeping to the prison rules and taking an active part in their treatment, thus earning additional privileges.15 This enables the prison to do without certain restrictions which would emerge from construction-related security measures. The windows in the probation group, for instance, have a large unguarded glass area through which a considerable amount of daylight can enter, and no perforated screens are used here. 3.3 Common showers Partitions in common showers are well suited to protect the privacy of the persons concerned. One prison has for instance installed a shower partition which does not begin until a height of roughly 30 cm above the ground, so that there is a limited view from the outside. This makes it possible to see what is happening in the shower room. The Commission considers it necessary to install at least one shower area with a partition. 3.4 Name badges The Joint Commission gained the impression that the atmosphere between inmates or patients and officers was more relaxed and friendly if all the officers of the respective facility wore name badges, as the staff of Diez prison do, and particularly that the possibility of identification led to greater transparency within the facility. This is now customary in many Federal Länder. cf. III.5.3. below cf. III.5.1.4. below 15 cf. III.5.1.3. below 13 14 21
