Abstract. Introduction. The relevance of the research topic is due to the need to develop and scientifically substantiate physiological criteria for assessing working conditions in difficult cases according to indicators of the functional state of the body (in accordance with the section "General hygienic assessment of working conditions" of Guideline R 2.2.2006-05). The aim of the work is to determine changes in the functional state of the body in workers of mental, visual-intense, physical activity on the basis of complex physiological and hygienic studies to substantiate quantitative physiological criteria for different classes of labor intensity. Materials and methods. Complex industrial physiological and hygienic studies included an assessment of the degree of labor intensity with the analysis of retrospective data, physiological studies of the central nervous system, visual analyzer, neuromuscular apparatus, cardiovascular system of mental workers (52 groups), visually stressful (32), physical labor ( 71 professional group). Statistical processing of the obtained data was carried out using the statistical software Statistika 10, Microsoft Excel 2010. Research results. It is shown that the depth and time of the onset of physiological changes depend on the degree of labor intensity, which makes it possible to calculate the percentage of decrease in functions, taking into account the intensity class of the labor process. The list of physiological criteria for confirming the class of working conditions is determined by the characteristics of labor activity, with mental work these are indicators of concentration of attention and the volume of working memory, with visually intense labor, the critical frequency of fusion of light flashes, with physical labor, muscle endurance and heart rate. Conclusions. Quantitative physiological criteria have been established for various types of labor activity, which provide a valid evidence-based assessment of the class of working conditions according to the characteristics of the intensity of the labor process and control of the levels of the functional state.

Processing Polymer

Polymer processing belongs to the category of hazardous industries and requires a deep and comprehensive analysis of the production environment from a hygienic point of view in order to minimize the negative impact on human health and components of the biosphere. The purpose of the study. It is important to study a set of adverse factors that affect employees in the process of processing polymer waste, to establish the relationship with the development of general and occupational diseases. Results and discussion. It has been established that the working conditions of the process of processing polymer waste have a combined effect on the body caused by a set of adverse production factors of different actions. The main ones are: dust in the air of the working area with polymer dust with mixed and unstable composition over time, noise, cooling microclimate, difficulty of work. The excess of maximum permissible concentration for dust load on the body of workers in the process of mechanical processing of PPV is from 1.35 times to 1.74 times, at the workplaces of the baler and shredder and unloading-packing operator (working conditions class 3.1). Exceedance of the sound pressure level in the range from 2 dBA to 15 dBA was recorded at all workplaces (working conditions class 3.2). The parameters of the microclimate at all workplaces, except for the forklift operator, belong to the harmful class of working conditions 3.1. According to the severity of the labor process, the working conditions of employees vary from allowable 2 (operator of the technological process) to harmful 3.2 (baler and shredder operator). In terms of intensity, the working conditions of all employees belong to harmful class 3.2, due to the significant noise load, which prevents the capture and transmission of information between participants in the processing process, as well as timely receipt of audio signals from the process operator and equipment. Mostly working conditions of employees in the process of processing PPV mixtures belong to class 3.2, except for the forklift operator (class 3.4). As for the integrated assessment, according to the hygienic classification, working conditions of operators of unloading-packing, crushing, technological process and baler are evaluated according to class 3.2, and the truck operator - 3.4 according to state sanitary rules and regulations "Hygienic classification of labor according to the indicators of harmfulness and danger and the intensity of the labor process" (order of the Ministry of Health dated 08.04.2014 No.248,), which can lead to the development of work-related diseases

Introduction. Laboratory practice is characterized by an increased hardness of the work process. In the research presented, a complex comparative assessment of the working conditions and functional condition of the employees of the laboratory center “Center for Hygiene and Epidemiology in the Voronezh Region” was carried out, in which a laboratory information system (LIS) is planned to be introduced into the practice. The assessment of the conditions of the labor process and the functional state of the employees was also carried out in the testing laboratory of the Center for Hygiene and Epidemiology in the Tambov Region, where the LIS software operates in the regular mode. Material and methods. The study was conducted on 170 specialists of testing laboratory centers. There are given data on the assessment of the hardness and intensity of the labor process of laboratories of different types of activity at workplaces of testing laboratory centers in the Voronezh and Tambov regions. There was performed a clinical examination of specialists of testing laboratory centers on the indications of the cardiovascular system: dynamics of the heart rate, systolic and diastolic blood pressure, minute blood volume during the working day. Results. Based on a comparative analysis of the results obtained, conclusions were drawn about the peculiarities of working conditions and performance indices of employees of testing laboratory centers in the dynamics of the working week. Differences in the formation of fatigue in the specialists of laboratories for hygienic and epidemiological profiles of activity among employees of a testing laboratory center, working without an information system introduced into the professional activity, have been observed in the second half of the working day, whereas those working with a laboratory information system the state of the body is correct from the physiological positions. Discussion. The class of labor conditions for specialists in testing laboratory centers, regardless of the profile of activity according to the severity of the work process, was identified as hard work of grade 1 (3.1), the class of working conditions for the intensity of the labor process as a hard work of grade 2 (3.2). Evaluation of the functional state of the body according to the cardiovascular system testifies to a noticeable fatigue in the second half of the working day among specialists working without software and information support. Conclusions. The data obtained as a result of the research made it possible to develop and offer a complex of preventive measures aimed at optimizing working conditions for the introduction into the professional work of personnel of testing laboratory centers. As a result, additions were made to the Instruction on labor protection of specialists of the Center for Hygiene and Epidemiology in the Voronezh Region.

Introduction. The profession of “machine operator in metalworking”, one of the most common professions in various industries, characterized by a large volume of abrasive operations, accompanied by dust formation, which creates a potential for the occurrence of diseases of the visual organ.The aim of the study is to provide a hygienic assessment of working conditions and occupational risk of visual organ pathology in metalworking machine operators.Materials and methods. Observation groups — machine operators for metalworking of two training groups (experience up to 5 years, experience of 6–20 years). Two comparison groups (administrative and technical personnel of the enterprise) are formed according to the same age-experience principle.Results. The working conditions of machine operators were classified as class 3.2. taking into account the severity and intensity of the work process and the noise level (80 dBA) in the workplace. Nitrogen oxide, carbon monoxide, and manganese were registered in the air of the working area in concentrations below the permissible concentration (PC), and the aerosol dihydroxide was registered above the PC in 25.8% of cases. In the main working groups, diseases of the anterior segment of the eye were more often registered, among which dry eye syndrome (DYS) prevailed (94.1%), chronic blepharoconjunctivitis (79.9%), persistent corneal opacification (21.7%). There was an increase in the prevalence of detected diseases with an increase in work experience (p≤0.05). In machine operators, the frequency of inhibition of lacrimal formation and decreased stability of the tear film was recorded significantly more often, with increasing work experience, the degree of violation of lacrimal formation and stability of the tear film increased. The chances of detecting pathology of the anterior segment of the eye in machine operators are 5.9 and 3.5 times higher than in the comparison group. There are different forces of connection, increasing with the increase of work experience in the profession, between the working conditions of machine operators and the occurrence of SHG (relatively strong), with chronic blepharoconjunctivitis and persistent corneal opacity (medium strength), which suggests the professional conditionality of this pathology.Conclusions. The results obtained suggest that the pathology of the anterior segment of the eye is professionally conditioned in metalworking machine operators and necessitate the introduction of preventive measures aimed at protecting the visual organ.

Introduction. Digital technologies are actively used in the work of specialists of medical centers of various profiles, which causes the impact on employees of a number of professional factors that determine the characteristics of their work. The aim of the study is to evaluate the influence of professional factors on the functional state of the employees' body and the glutathione system as an objective indicator of stress based on the analysis of the subjective perception of the medical center employees of the specifics of working with personal computers and psychophysiological testing. Materials and methods. The study involved 109 specialists of medical centers (25 ophthalmologists, 31 representatives of the secondary medical staff - nurses and paramedics, 53 office employees). The anonymous survey concerned the assessment of working conditions and their impact on the functional state of the body of the respondents. Performance and stress tolerance indicators were evaluated using three standard questionnaires. The study of 66 subjects' levels of glutathione in the blood: total, reduced, oxidized and the ratio of reduced and oxidized - was used to analyze the relationship of the neuro-emotional nature of labor with the reaction of oxidative stress. Statistical processing of the obtained data was carried out using traditional methods of variation statistics and calculating the value of the odds ratio (OR) with a 95% confidence interval (CI). Results. The survey revealed a significant proportion of people in all groups of respondents who constantly use computer technology in their work. Describing the quality of the processed information, doctors more than representatives of other groups note its complexity, importance, negative emotional color, a high degree of responsibility and tension. Doctors more often than average medical staff and office workers associate the manifestation of fatigue with an uncomfortable state of the visual organ, nervous system, and musculoskeletal system. The subjects showed reduced performance and stress tolerance with the most pronounced negative trends in the group of doctors. Changes in the glutathione system were detected, indicating the presence of oxidative stress in 40% of ophthalmologists and office workers, and in half of nurses. Conclusions. The work of specialists of medical centers of various profiles in accordance with their assessment is characterized by high nervous and emotional stress, due to the need to process a significant amount of complex and important professionally significant information. Subjectively noted by respondents the influence of working conditions on the functional state of the body is confirmed by indicators of the glutathione system, which can be used as indicators of nervous and emotional stress.

Introduction. Professional groups of railway workers engaged in the repair of wagons are directly responsible for the safety of railway traffic. The analysis of literature testifies to insufficient attention of researchers to the hygienic problems associated with labor activity of workers of wagon-repair production.The aim of the study is to assess the occupational risk to the health of wagon repair workers, due to the impact on them of factors of the working environment and the labor process.Materials and methods. The study used comprehensive hygienic studies using the methodology of occupational risk to worker’s health.Results. The leading factors of the working environment (class of working conditions 3.2–3.4), which are exposed to workers depending on the specifics of the work performed. Identified professional groups with medium (significant) high (unbearable) and very high (intolerable) category of a priori occupational risk: in wagon meintenance workshop — 17 groups (94% of jobs), in a wagon assembly workshop — 11 groups (80% jobs), in wagon wheel workshop — 3 group (100% jobs). At the same time, according to the request for medical care, employees were diagnosed with isolated cases of occupational diseases.The levels of morbidity with temporary disability of employees of the main workshops are statistically significant (p<0.05) higher than those of the control group in 1.4–1.9 times. The influence of the complex of chemical factors of low and medium intensity on the levels of morbidity of respiratory diseases in the group of workers of the wagon wheel workshop, which were 1.7–2.0 times higher than in the control group, is confirmed by the average degree of causation of the production condition of this pathology (RR=1.7; EF=42.0%).The combined effect of vibration and severity of the labor process forms a high level of temporary disability of employees of the main workshops in connection with diseases of the musculoskeletal system, which was 2.7–4.4 times higher than in the control group, and also determines the prevalence of this pathology in the structure of diseases detected on medical examinations (23.2%). Diseases of the musculoskeletal system are caused by the production of employees of the wagon meintenance workshop (RR=3,9; EF=74,9%), as the most unfavorable in terms of hygiene on these factors.The stressful influence of the complex of harmful production factors on the health of wagon repair workers is manifested by the high risk of diseases of the cardiovascular system, gastrointestinal tract, neurological disorders, violation of adaptation of the cardiovascular system in 97% of the examined, as well as the predominance of diseases of the digestive system and circulatory system detected on periodic medical examinations.Conclusions. Harmful working conditions (class 3.1–3.4) cause the suspected occupational risk from small (moderate) to very high (intolerable) to 100% of the jobs of wagon repair workers. The results of the study of morbidity and risk of pathology indicate a significant risk of damage to the health of workers.
