Prisoners can stay outdoors, on the fresh air, from the morning till the evening. However, in the view of the monitoring group, the yard of the Institution’s building no. 6 is small for the prisoners’ recreational purposes. There are not necessary conditions for exercising in the yard. The prisoners have no access to a sports ground. 2.4.1.10.  PENITENTIARY INSTITUTION NO. 17 The Institution no. 17 has different types of cells. The cells are designed for 10, 12, 18 and 24 prisoners and have the area of 30.4m2, 32m2, 47m2 and 55m2 respectively. The floor area in the residential cells does not always comply with the requirement under Article 15(2) of the Code of Imprisonment.100 The cells in the residential buildings have two iron-bar windows. Repair is needed in the cells. Natural and artificial light in the cells is sufficient. The residential buildings have a central heating system. The toilets in the residential buildings are small-size and are isolated; the ceiling and walls are humid; no flush tanks are installed. There are two quarantine rooms in the Institution. If these rooms were used to the full of their capacity, they would be extremely cramped, because of the small area and the beds inside. In particular, if all the 24 prisoners are accommodated in the first room and 32 prisoners in the second room, infection control would be very difficult and infectious diseases could easily spread amongst the prisoners. Residents of half-open residential buildings can enjoy their right to outdoor exercise, use a telephone and engage in sports activities between 07:00 and 21:00 hrs. Residents of closed-type residential buildings are entitled to 1 hour of outdoor exercise per day. The exercise yards of half-open residential buildings are equipped with tables, chairs, sports grounds and exercising equipment. There are shared toilets and washstands in the exercise yards. There is no sports and recreational equipment in the exercise yard of the closed-type regime building. At the time of the Special Preventive Group’s visit, the sewerage system was damaged in the exercise yard of the 1st and 2nd regime buildings and there was a puddle of water in the yard. The monitoring group inspected the shower rooms in the Institution’s regime buildings. In the shower rooms, there is no heating, the central ventilation system is dysfunctional. The floor tiles are damaged. The sewerage system operates with defects which results in the shower room getting flooded and humid. The shower rooms in the Institution’s closed-type regime building are not isolated. There is no artificial or natural ventilation in the shower room. 100 Under Article 15(2) of the Imprisonment Code, the floor area per each convicted prisoner in all types of places of deprivation of liberty should not be less than 4 square meters. 64 NATIONAL PREVENTIVE MECHANISM OF GEORGIA
