(3) Segregated prisoners are placed in close confinement. Prisoners in close confinement are subject to
increased supervision. They are escorted whenever they must leave their cells. They are quartered in cells
specifically set aside for this purpose. Close confinement quarters must be adequately lit, heated, and ventilated.
There must be 35 square feet of unencumbered space for the single cell occupant. When confinement exceeds
10 hours per day, there must be at least 80 square feet of total floor space per occupant. Space allotment for
individual cells or rooms constructed prior to 1 January 1995 will be at least 8 feet long, by 6 feet wide, by 8
feet high (minimum inside measurements). Solid doors are used only when they are needed to keep noisy
prisoners from disturbing others. Sleeping accommodations are elevated from the floor.
