- 44 87. The CPT considers that transfers of prisoners should always be carried out in a humane, secure and safe manner. When vehicles are equipped with secure compartments, individual cubicles measuring less than 0.6m² should not be used for transporting a person, no matter how short the duration. Individual cubicles measuring some 0.6m² can be considered as acceptable for short journeys/distances only; however, cubicles used for longer journey/distances should be much larger. Compartments or cubicles intended to transport more than one person should offer at least 0.6m² of personal space. Further, all transport vehicles should be clean, sufficiently lit and ventilated, and heated or air-conditioned appropriately.48 In addition, necessary arrangements should be made to provide prisoners with drinking water as required and, for long journeys/distances, with food at appropriate intervals. In the context of long journeys, arrangements should be made to allow prisoners to have access to sanitary facilities or to satisfy the needs of nature in conditions offering sufficient privacy, hygiene and dignity. When travelling by road, this implies the organisation of regular stops. Prisoners should be transported in vehicles suitably designed and fit for that purpose, taking due account of all relevant safety requirements in order to protect prisoners. In particular, all vehicles which are used for the transfer of prisoners should be regularly maintained and equipped with appropriate safety devices such as safety belts. The Greek authorities should also take steps to prevent intimidation and verbal abuse being perpetrated by prisoners against their fellow passengers. In particular, women should not be placed together with men in the same transfer vehicles. 88. The CPT reiterates its recommendation that the Greek authorities urgently review the current arrangements by which the Hellenic Police transfer prisoners in Greece. In particular, they need to ensure that: • the capacity of the secure coaches is reduced as no more than two persons should be held in the 1.2m²-compartiments and no more than one person in the 0.6m²-cubicles. In the longer term, the existing vehicles should be adapted or replaced, taking into consideration the above-mentioned standards of personal space; • all secure transport vehicles are clean, sufficiently lit and ventilated, and heated or airconditioned appropriately; • prisoners are provided with drinking water as required and, for long journeys/distances, with food at appropriate intervals; • prisoners are offered access to sanitary facilities at regular intervals, in conditions offering sufficient privacy, hygiene and dignity; • all transfer vehicles are regularly maintained and equipped with safety belts, so as to guarantee the safety of prisoners during transfers. They should also be fitted with means to enable prisoners to communicate with escort staff; • appropriate measures are taken to prevent prisoners being subjected to intimidation and verbal abuse by fellow prisoners. In particular, female prisoners should not be transferred together with male prisoners in the same secure vehicle. 48 See also the CPT factsheet on transport of detainees of June 2018: CPT/Inf (2018) 24.
