- 21 Cells should be kept in a satisfactory state of repair and in a clean and hygienic condition. Persons in custody should be allowed to comply with the needs of nature when necessary, in clean and decent conditions, and be offered adequate washing facilities. Toilet facilities should offer an adequate degree of privacy. Consequently, the CPT recommends that firm instructions be issued to ensure that cells and sanitary facilities used by detained persons are kept in a reasonable state of cleanliness, and that such persons have ready access to a proper toilet facility at all times. Detained persons should also be in a position to wash and, in appropriate circumstances, to change their clothes and take a shower; persons detained for an extended period should also be provided with toiletries (e.g. soap and towel, toothpaste, etc.). Further, the CPT recommends that all persons detained for 24 hours or longer be offered the opportunity of outdoor exercise every day. 33. The CPT also wishes to recall that detained persons should have ready access to drinking water and should be given food at appropriate times, including at least one full meal (i.e. something more substantial than a sandwich) every day. In general, findings from the 2005 visit confirmed that detainees were receiving sufficient food8 although in some police stations it was not regular and warm meals were served cold. On the other hand, access to drinking water was a source of concern in many establishments visited. The CPT recommends that clear instructions be issued with a view to ensuring that detained persons receive appropriate food at regular intervals (including at least one full meal every day), and that they have ready access to drinking water at all times. 34. Finally, the CPT recommends that the Greek authorities take immediate steps to bring to an end the practice of holding persons, in particular immigration detainees, for prolonged periods in ordinary law enforcement agency detention facilities; they should be accommodated in centres specifically designed for such use, taking due account of the criteria repeatedly advanced by the CPT.9 d. Petro Rali special holding facility 35. The delegation had an opportunity to visit this new facility in Athens, which will have a capacity to hold 180 prisoners undergoing transfer around the country, and some 380 individuals being held for administrative detention for periods up to three months. At the time of the visit the facility had not yet opened10. The 560 detainees would be held in two different Wings, located respectively on the second and third floors of the building (200 and 180 on the second floor, and 180 on the third floor). Half the second floor was for remanded and sentenced prisoners undergoing a transfer or awaiting a court appearance, and whose stay would be short-term; the other half of the second floor and the whole of the third floor would accommodate irregular foreigners. There were two open-air exercise yards. 8 9 10 The daily allowance of 5.97 € per detainee for food still applied. cf. CPT/Inf (2001) 18, Part II, paragraphs 35 and 36 and CPT/Inf (2000) 31, paragraph 25. The facility was scheduled to be inaugurated on 27 September 2005.
