if they had the opportunity, they would participate in various activities with pleasure. Every place used by the prisoners, especially the bedrooms, should fully comply with sanitary requirements. In addition, sufficient attention should be paid to the climate conditions, particularly to the cubic contents of air, the minimum space, heating and ventilation.244 In every establishment where the prisoners live and work the windows should be of the sufficient size so that the inmates have the possibility to read and work in the daylight and should be constructed in a way that the provision of fresh air should be ensured, whether the artificial ventilation system exists or not. Artificial lightning should be sufficient for the prisoners to read or work without the risk of deteriorating their eyesight.245 In the establishment N12, the living block of the prisoners involved in the maintenance service is outdated and needs renovation. The inmates are buying the ventilators at their own expense in order to cool the rooms. In winter, they use the electric heaters. The cells do not have the sanitary knots or water. In the maintenance section block there is one shower and kitchen that are available for the prisoners for 24 hours, since the cells are not closed. Several convicts noted that the sanitary knots are not enough for the inmates and they often have to stand in line to take care of their personal hygiene. In one of the cells, with the space of 6.29 square metres, 2 inmates were living. Besides, the cell is not in fact aired since the window is too small. The convicts stated that they have been recently transferred to the Estalishment and that is why they are temporarily placed in this cell. They have also noted that in the nearest future, it is planned to transfer one of them to another cell. In the establishment N6, 2 barracks are allocated for the prisoners involved in the maintenance service, responsible for cleaning. The buildings are depreciated, however, the living conditions are satisfactory. Prisoners in charge of cleaning are in better conditions compared to the rest of the prisoners since the institution is closed and other inmates are taken out of the cells only during the walk. While the movement is not restricted for the inmates of the maintenance service, responsible for cleaning. In the establishment N7, the inmates of the maintenance service, responsible for cleaning are living in one cell. The cell is located on the first floor of the institution, which is under the land surface from one side. There is no natural light or artificial ventilation in the above cell, the lightning is only artificial. The cell does not have a sanitary knot. The cell is damp and outdated, in fact not compatible for living. During the monitoring carried out in the establishment N6, the living conditions of the prisoners from the maintenance service, responsible for cleaning was also checked. The condition in the cell accommodating 3 prisoners who refused to work is unbearable. 244 Nelson Mandela Rules, Rule 13. 245 Ibid, Rule 14. 150 NATIONAL PREVENTIVE MECHANISM (NPM), 2015
