- 55 - 125. As to training, many of the prison officers met by the delegation stated that the training offered was insufficient. More specifically, certain complained that, besides a three month theoretical course upon first joining the prison service, they had received no refresher or educational courses to assist them with their tasks. The CPT would like to receive detailed information on the courses that all new prison officers undertake upon joining the service, as well as information on the in-service training facilities for existing staff. The CPT also wishes to stress the importance of appropriate training in control and restraint techniques (i.e. manual control). The CPT reiterates its previous recommendation that training in control and restraint techniques be made available to all prison officers; it would also like to receive detailed information on the training provided and the numbers of officers concerned. b. contact with the outside world 126. The importance of prisoners being able to maintain good contact with the outside world is recognised in the Prison Law of 1999 (cf. Articles 51 to 58), and the necessity to promote such contacts has been stressed in previous CPT reports. In general, the practice as regards access to the telephone and correspondence can be considered as satisfactory. However, in certain establishments additional efforts need to be made; for example, Chios Judicial Prison has only one telephone for more than 160 prisoners, and it often becomes the object of disputes.37 127. As regards visits, previous CPT recommendations on this subject have not yet been implemented. Visits still normally take place under closed conditions, allowing no physical contact between prisoner and visitor. Moreover, visiting time is limited to 30 minutes or less a week. At Chios Judicial Prison, there were almost no visits as a result of its geographical isolation. The CPT reiterates its recommendations: that the Greek authorities review the arrangements for visits, with a view to allowing them to take place under reasonably open conditions; that a more generous visiting time be offered; and that special rules on visiting arrangements for difficultto-access prisons be drawn up, which should address inter alia the length of visits and possible forms of assistance to visitors. 37 The problem is accentuated in this prison not only due to the large numbers of foreigners but also because the vast majority of Greek prisoners come from distant islands or the mainland – hence there are virtually no visits and the telephone is the primary means of communication with family and even lawyers.
