150. In each of the CCACs visited, the core management staff under the Reception and Identification Service (RIS) was relatively small. For example, at Kos CCAC, there were only 33 RIS employees responsible for managing the centre. They were supported by a host of other agencies, notably a private security company (84), the Hellenic Police (66), the Asylum Service (18), eight translators and one teacher. In addition, various EU and UN agencies had some 49 personnel working in the centre and there were four NGOs present with 19 personnel.58 However, only the RIS personnel could address issues pertaining to the management of the centre. The private security personnel had a very static role as they were only responsible for locking and unlocking the various internal gates of the centre and for checking who entered and left the main entrance of the centre. They had no mandate to intervene or engage with residents in the centre. Likewise, the Hellenic Police performed only a security function, patrolling the perimeter, controlling access to certain sections of the CCACs and having an intervention group on stand-by if any incidents arose. 151. Given the importance of being able to engage with new arrivals in the CCACs and to ensure that their basic needs are met, it is important that there is a good communication with staff. RIS staff should be present in all the accommodation blocks every day to address any needs arising. It is also important for more staff with appropriate communication skills to be employed by the CCACs, who can act as cultural mediators and provide basic information on life in the centres and the procedures being undertaken to process their cases. Teams of social workers, psychologists and interpreters, such as those provided by the NGO Zeuxis to the unaccompanied minors’ “safe zone” at Samos CCAC, should be operating in all the accommodation sections in every centre. The Committee considers that a better deployment of the available staff resources could be put into place, which would result in more interaction and better communication with the residents. The CPT recommends that the Greek authorities review the staffing needs of the CCACs with a view to reinforcing the presence of personnel within the various accommodation sections of the centres. Further, such staff should be provided with the necessary training, notably inter-personal skills, for working with foreign nationals. In addition, a contingency staffing roster should be drawn up which can be deployed whenever the number of residents in the centres rise above their normal operational capacity. 58. At Samos CCAC, similar staffing ratios were in place with 68 RIS personnel, 108 private security, and 66 Hellenic Police officers. The staffing levels at Lesvos CCAC were slightly better with 80 RIS employees, 110 private security, 187 police and border guards and another 171 employees to cover cleaning, maintenance, catering and other support roles, as well as representatives from various EU and UN agencies and NGOs. At the Fylakio RIC, the staff included three managers, nine police officers carrying out the registration procedures, 33 contracted staff, 32 cleaners, 53 private security officers and 42 police and border guard officers, as well as 23 persons from various agencies such as UNHCR, IOM, EUAA, Arsis and Metadrasi. 45
