institution. Ninth General Report [CPT/Inf (99) 12] and 30 § 29 A well-designed juvenile detention centre will provide positive and personalised conditions of detention for young persons deprived of their liberty. In addition to being of an adequate size, well lit and ventilated, juveniles' sleeping and living areas should be properly furnished, well-decorated and offer appropriate visual stimuli. Unless there are compelling security reasons to the contrary, juveniles should be allowed to keep a reasonable quantity of personal items. § 30 The CPT would add that, in certain establishments, it has observed a tendency to overlook the personal hygiene needs of female detainees, including juvenile girls. For this population in custody, ready access to sanitary and washing facilities as well as provision of hygiene items, such as sanitary towels, is of particular importance. The failure to provide such basic necessities can amount, in itself, to degrading treatment. United Nations Rules for the Protection of Juveniles Deprived of their Liberty. General Assembly resolution 45/113 Principle 31 Juveniles deprived of their liberty have the right to facilities and services that meet all the requirements of health and human dignity. Principle 32 The design of detention facilities for juveniles and the physical environment should be in keeping with the rehabilitative aim of residential treatment, with due regard to the need of the juvenile for privacy, sensory stimuli, opportunities for association with peers and participation in sports,physical exercise and leisure-time activities. Principle 34 Sanitary installations should be so located and of a sufficient standard to enable every juvenile to comply, as required, with their physical needs in privacy and in a clean and decent manner. Principle 36 To the extent possible juveniles should have the right to use their own clothing. Detention facilities should ensure that each juvenile has personal clothing suitable for the climate and adequate to ensure good health, and which should in no manner be degrading or humiliating. Juveniles removed from or leaving a facility for any purpose should be allowed to wear their own clothing. Principle 37 Every detention facility shall ensure that every juvenile receives food that is suitably prepared and presented at normal meal times and of a quality and quantity to satisfy the standards of dietetics, hygiene and health and, as far as possible, religious and cultural requirements. Clean drinking water should be available at any time. The living conditions prevailing in juvenile detention centres and juvenile shelters visited in 2010 by the National Preventive Mechanism were diversified, however, the overall image of those establishments should be assessed as good. NMP's reservations were raised by the conditions in transition rooms: the rooms had no furniture, to the floor only wooden boards were fixed on which the juveniles put their mattresses made available to them at night (e.g. JDC in Laskowiec). Also, the condition of the sanitary installation at the transition rooms and isolation room in that establishment was assessed as bad. In addition, the NMP members pointed out the need to conduct general or emergency renovations of some of the rooms for the juveniles (JDC in Studzieniec, JDC in Falenica) and workshop rooms (JDC in Studzieniec). In the majority of the visited establishments, it was recommended to equip shower cabins with anti-slip mats and curtains as well as with missing ladders and protections in the upper beds (eg. JDC in Laskowiec, JDC in Studzieniec, JDC in Mrozy).
