Under general provisions, the Act mandates that inmate management shall promote the inmate's adjustment in society and counteract the detrimental consequences of deprivation of liberty. Prison treatment shall be planned and implemented with collaboration between the various bodies that compose the national prison and probation system. Detailed provisions on prison treatment require that inmates shall be provided with suitable work and opportunities for physical exercise and leisure activities. In preparing an inmate for release, special efforts must be made to provide suitable employment or other means of support, as well as suitable living accommodation. The separation of an inmate from other inmates is permitted in the interests of national security, to prevent the inmate from exerting a negative influence on other inmates, and to conduct a physical examination of the inmate's bodily cavities. Other provisions pertain to inmate personal possessions, inmate mail, visitation, telephone use, furloughs, and the confiscation of alcoholic beverages and other intoxicants from inmates.
