В статье анализируются вопросы правового регулирования и организации мероприятий по обработке специального транспорта, используемого для конвоирования осужденных и лиц, содержащихся под стражей, в целях недопущения распространения заболеваний, вызванных новой коронавирусной инфекцией (COVID-19). Охарактеризована правовая регламентация санитарно-гигиенической и противоэпидемиологической деятельности в условиях учреждений, обеспечивающих изоляцию от общества. Показан комплекс проблем, связанных с обеспечением необходимых санитарно-гигиенических условий при перевозках осужденных и лиц, содержащихся под стражей. Исследован вопрос о критериях отбора дезинфицирующего средства, применяемого для обработки специального транспорта. Сформулированы дополнительные требования, предъявляемые к дезинфицирующим средствам, в современных условиях распространения новой коронавирусной инфекции (COVID-19). Сделан вывод о целесообразности сочетания химических и физических способов проведения дезинфекции. Предложено комбинированное использование химических аэрозольных методов и физических ультрафиолетовых дезинфекционных технологий, реализуемых посредством бактерицидных облучателей-рециркуляторов воздуха, предназначенных для обеззараживания воздуха ультрафиолетовым излучением в различных закрытых пространствах, включая салоны транспортных средств. Затронуты вопросы организации дезинфекционных пунктов в учреждениях уголовно-исполнительной системы Самарской области. The article analyzes the issues of legal regulation and organization of measures for processing special transport used for convicts and persons in custody escorting in order to prevent the spread of diseases caused by a new coronavirus infection (covid-19). The article describes the legal regulation of sanitary-hygienic and antiepidemiological activities in institutions that provide isolation from society. The complex of problems related to ensuring the necessary sanitary and hygienic conditions during transportation of convicts and persons in custody is shown. The question of the selection criteria for the disinfectant used for the treatment of special transport is investigated. Additional requirements for disinfectants are formulated in the current conditions of the spread of a new coronavirus infection (COVID-19). The conclusion is made about the expediency of combining chemical and physical methods of disinfection. The combined use of chemical aerosol methods and physical ultraviolet disinfection technologies implemented by means of bactericidal irradiators-air recirculators designed for disinfection of air with ultraviolet radiation in various enclosed spaces, including vehicle interiors, is proposed The issues of organization of disinfection points in institutions of the penitentiary system of the Samara region were discussed.

The effects of foulant chemical composition on ultraviolet (UV) absorbance of fouled quartz sleeves in UV disinfection systems were studied. Statistical analysis was conducted to examine the effects of nine fouling chemicals on the UV transmittance changes of fouled quartz lamp sleeves. The results demonstrated that the main effects were attributable to surface concentrations of iron and manganese. The surface concentrations of calcium and copper had no significant effects on the UV absorbance of fouled sleeves. The interaction effects of copper with iron and magnesium with manganese were also revealed from the statistical analysis. The model is able to give reasonable predictions of the UV absorbance characteristics of foulants from other UV systems. However, several limitations of this model were identified. First, the model does not accurately predict the absorbance at relatively high chemical surface concentrations. Second, the model does not account for the possible effects of anions and organics on UV absorption of fouled quartz sleeves.
