CAT/OP/PRT/1/add.1 specific skills in suicide prevention. Twenty-one workers were enrolled and fifteen effective participations were verified. 37. The regulation of the general principles on containment is part of the subjects to be included in the revision of the Mental Health Law 36/98. III. Prisons A. Material conditions of detention in prisons 38. The Subcommittee recommends the State party to broaden the work, education, rehabilitation and recreation opportunities for prisoners. Such opportunities facilitate rehabilitation of prisoners and their future reintegration in the society. The Subcommittee recommends that fairly remunerated work opportunities be made available to all detainees. The State party might consider dividing working hours between several prisoners to allow more people to be engaged in purposeful activities. 39. It should be mentioned that a continuous investment to qualify prison treatment, defined as “the set of social rehabilitation activities and programs aimed at preparing the prisoners for liberty, through the development of their responsibilities, the acquisition of competencies that allow them to choose a socially responsible way of life, without committing crimes and to provide for their needs after their release” [article 5 (2) of the CEPMPL], has been made. 40. Recognizing the importance of prison treatment activities in the process of rehabilitation and social reintegration of prisoners, the DGRSP seeks to organize a differentiated educational and vocational training offer targeted at individually assessed needs. 41. While the delegation did not consider the food, shown by the prisoners, of particularly bad quality, the State party is urged to check on the food hygiene, nutritious value, the variety and the quality of the food served on a regular basis. The Subcommittee encourages the State party to ensure that all inmates receives sufficient supplies of hygienic and cleaning products. 42. With respect to this recommendation, it should be highlighted that four daily meals are provided (breakfast, lunch, dinner and an evening reinforcement delivered along with the dinner) and that prison establishments provide for specific diets prescribed by doctors and/or requested by the prisoners in order to respect their religious or philosophical beliefs. 43. Food provision to prisons is a contracted external service and food’s quality and quantity of each meal obey strict criteria, defined by a physician and a nutritionist, and are subject to a daily check in each prison. Where, in the course of this daily check, something is not in accordance with the defined criteria, the meal is replaced and in certain extreme cases, penalties may be applied to the supplying company, in accordance with the existing contract. 44. The Subcommittee urges the State party to ensure that the material conditions in detention do not pose such health hazards and recommends the State party to ensure that essential maintenance is carried out, including through creating maintenance paid or voluntary work opportunities for inmates. 45. The conservation and maintenance of prison spaces is a constant task and is frequently renewed. In general, prison cleaning and maintenance services, as recommended, is carried out by duly paid prisoners. 46. The Subcommittee recommends the State party to ensure that the call bells are functional in all facilities and that units are staffed in a way that makes responses to alarms possible. 6
