Effects produced by hazardous occupational factors on workers employed in oil extraction often occur under low temperatures when workers have to perform their tasks outdoors. Our research goal was to assess a contribution made by cooling meteorological factors into health risks for workers performing their job tasks outdoors during a cold season in order to substantiate priority prevention activities. The research was performed on workers employed by a large oil extracting company who spent different amount of time outdoors during a cold season. A posteriori group risk was assessed according to the Guide as per results obtained via periodical medical examinations in 2017–2018. Working conditions were assessed basing on a report obtained via special assessment of working conditions and industrial control results. Cooling microclimate was assessed according to G 2.2.2006-05. Basing on the results of a priori group risk assessment, work places were ranked as per health disorders probability. It was shown that in-plant noise was the leading factor causing health risks. Besides, when working experience exceeded 20 years, cooling meteorological conditions also made a substantial contribution into risks occurrence. Obtained results indicate that it is necessary to develop medical and prevention activities for workers who have to spend a lot of time outdoors in areas with cold climatic conditions.

Introduction the aim of the study. The implementation of risk-oriented model organization of the control and supervision activities of Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing with the assessment system of potential dangerous objects requires the creation of multiannual reliable database about the occupational working conditions which must include results of the production control for enterprises of all industries of the national economics of the Russian Federation. The aim of the study was to study the effectiveness of the use of the production control (PC) results of working conditions for the provision of sanitary - epidemiological wellbeing of the population. Material and methods. The study was conducted on materials of Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing on the Leningrad region, Petrostat for 2009-2012. In analysis there were included software and PC results of working conditions in 420 industrial enterprises of various branches of the Leningrad region industry. To develop a regional model of PC program planning based on critical control points there was chosen the major refinery in the Leningrad region - Limited Liability Company “Production Association” Kirishinefteorgsintez “(LLC “PA “KINEF”). 3960 protocols of laboratory and instrumental investigation results of working conditions were made for the purpose of PC control on LLC “PA “Kinef” and 1921 protocols of PC results - on 420 industrial enterprises of the Leningrad region were analyzed. Results. The performed analysis revealed a number of problems to the application of PC results for the aim of working conditions optimization of employees, planning disease prevention program and the assessment of object’s sanitary-hygienic wellbeing. The method of critical control points (CCPs) in the planning of PC programs on the large industrial enterprises is proposed to use. On the example of “Kinef” there was shown the efficiency of the use of CCPs in order to optimize the PC programs. There was developed and implemented the regional model of the use of PC programs which allows to solve the problem of the significant increase of preventive orientation and efficiency of PC program at enterprises of all sectors of the national economy of the Russian Federation as an important element of the management of sanitary - epidemiological population wellbeing regarding to the maintenance of healthy and safe working conditions. Conclusions. Existing legal regulatory and methodological framework regulating the organization and performance of PC control and social - hygienic monitoring in the Russian Federation requires significant changes and additions what allow to increase the reliability of the objects classification on groups of sanitary-epidemiological wellbeing and to realize a risk-oriented approach to control and oversight activities.

Introduction. One of the key factors influencing on the quality of drinking water is the high level of water sources of the pollution, leading to the need for large-scale water treatment. There are remained risks, the consequence of which may lead to the deterioration of the quality of drinking water which is conveyed to the population. It is necessary to introduce effective technologies of water treatment, informative and reliable approaches for the assessment of epidemiological safety and harmlessness of drinking water. One of the priority directions is the development and use of methods of the integral assessment of drinking water quality. Aim of the study. For this purpose there was developed a method for the integral assessment of drinking water relying upon indices of the chemical harmlessness and a method for the comprehensive assessment of the risk of bacterial intestinal infections transmitted by water. There is proposed a method of assessing the quality of drinking water in terms of epidemiological safety, based on the fundamental principles, and providing a probabilistic approach to the assessment of health risk. Conclusion. The development, argumentation and implementation of the method of the integral assessment of the probabilistic health risk with the combined effect of chemical and microbiological agents contained in drinking water remain to be actual.

Introduction. To prevent health disorders under the influence of cooling meteorological factors of open production sites, the assessment of the individual characteristics of the employee’s thermoregulation is of particular importance. The purpose of the study was to describe the individual characteristics of thermoregulation of employees of an oil producing enterprise when working in open production sites during the cold season. Materials and methods. We studied the employees of the oil-producing enterprise of Western Siberia, performing labour operations in open production sites during the cold season (operators, process plant machinists, repairmen). An assessment of general and local violations of thermoregulation of the body of workers was carried out using objective assessment methods (assessment of the thermal state of the body in seventy six people, skin thermometry with cold load - 54 people) according to approved methods. The duration of work in the open area of the workers included in the study ranged from 12 to 31 hours during a 40-hour work week. Results. According the assessment of the thermal state of workers, in 18.8% of workers, the personal indicators for assessing the thermal state were found to fail to correspond to the recommended values in the guidelines. Evaluation of the results of skin thermometry with a cold load in workers performing labour operations in open production sites under cooling conditions of the cold season of the year made it possible to establish the average values of temperature indicators in the study group to indicate the presence of initial signs of violations of the thermal control of the body and neurocirculatory disorders in the hands and fingers. An assessment of individual characteristics showed general and local violations of thermoregulation to be associated with the duration of work at open production sites, the objective indicators of local violations of thermoregulation were additionally affected by the employee’s smoking habit and work experience. Limitations. Significant time costs for assessing the general and local thermoregulation of the employees of the enterprise and distracting them from performing labor operations during the shift can be attributed to the limitations of the methodology. Conclusion. For the first time, the revealed features of thermoregulation in oil production workers in Western Siberia made it possible to develop targeted medical and preventive measures.

Introduction. The extraction of minerals is associated with a permanent or periodic stay of workers at open production sites. However, there is an underestimation of the impact of working meteorological factors on the health both in the system of regulation and control over working conditions. The aim of the study is to scientifically substantiate approaches to the development of preventive measures to minimize the risk of health disorders and inform about the risk when working in an open area during the cold season. Materials and methods. The study included employees of the oil-producing enterprise of Western Siberia Samotlorneftegaz, performing labour operations in open areas during the cold season (operators, machinists, repairmen). The study included three stages: a priori risk assessment, a posteriori risk assessment, and an assessment of the individual characteristics of employees. The a priori risk assessment based on production control data and a special assessment of working conditions for the period from 2014 to 2018. A posteriori risk assessment based on data from periodic medical examinations. Personal characteristics based on the results of a questionnaire, in natural and model tests. Results. A quantitative assessment of a priori and a posteriori risk made it possible to identify groups of workers with a significant risk of developing occupational and general pathology, as well as to prioritize preventive measures aimed at preventing the harmful effects of working environment factors and the labour process on the health of an employee. The assessment of local and general violations of thermoregulation in workers performing labour operations in open areas during the cold season made it possible to establish individual risk factors: prolonged work in open areas (more than 60% of working time), the presence of chronic pathology, smoking habit and work experience. Limitations. As part of this study, the assessment of the health status of workers based on data from periodic medical examinations. At the same time, the study does not include the results of medical examinations at the place of residence of workers, which can expand data on the health status of workers and be the subject of further research. Further research on the stated topic may be associated with the need to assess an additional list of individual characteristics when working in an open area during the cold season, taking into account genetic and biochemical markers. Conclusion. The results obtained made it possible to substantiate a set of measures to minimize the risk of health disorders at the level of primary prevention, as well as to propose measures at the level of secondary prevention.

Natural resources extraction involves continuous exposure to cooling meteorological factors typical for open production grounds. This necessitates relevant health risk assessment and management of health risks caused by exposure to these harmful occupational factors. However, the available risk assessment models do not provide a possibility to perform complete assessment of the existing risks created by exposure to meteorological hazards. The study design included the following. We performed hygienic assessment of working conditions and health of workers employed by “Samotlorneftegaz” Joint Stock Company (JSC) who had to perform their work tasks under exposure to cooling meteorological factors on open production grounds; the assessment involved calculating the group health risk. Individual peculiarities were assessed using subjective (547 people took part in questioning) and objective assessment methods (76 people took part in estimating thermal state of their bodies and 54 people participated in thermometry with cold stress). Finally, we assessed prior and posterior risks. The prior group risk assessment made it possible to identify risk groups who had a significant risk of developing occupational and non-occupational diseases and to rank working places as per health hazards. The posterior risk assessment confirmed the results produced by the prior risk assessment regarding potentiating negative effects produced by cooling meteorological factors. The assessment of developing general and local thermoregulation disorders revealed that certain individual peculiarities made a substantial contribution into their development. Among them, we can mention long-term outdoor work (60 % of work time or more) under exposure to cooling meteorological factors; a chronic pathology; tobacco smoking. The results produced by this study allowed us to suggest an integrated model for risk assessment, management and communication about health risks caused by working under exposure to cooling meteorological factors.
