The rail transport is the one of the leading sectors of the national economy. More than 50% of the employees of the enterprises of the railway complex work under the unfavourable impact of hazardous and dangerous substances and occupational factors. In the literature issues of working conditions and health of employees of railway carrepairing plant are hardly highlighted. The aim of the study is the evaluation of the morbidity rate shaped under the influence of harmful occupational factors for the elaboration of preventive measures. In the work there were used generally accepted methods of hygienic studies, analysis of morbidity rate with temporary disability (TD), according to records of periodic medical examinations, occupational prevalence. The railway car-repairing plant was established to be characterized by the complex of harmful factors of the working environment and labor process: noise, local vibration, industrial aerosols of complex composition, chemicals, low light, hardness of the labor process. The levels of incidence with temporal disability in the studied groups, depending on the work seniority in the harmful labor conditions, significantly decrease with the experience from 5 to 9 years and increase with the experience more than 10 years. Executed in-depth analysis as of the both morbidity rate and TD, as well results of periodic medical examinations of workers of main shops shows that overall indices of the morbidity rate and TD are significantly higher than in the comparison group; levels of the morbidity rate and TD in the observed groups significantly decline depending on the length of service in hazardous working conditions with a length of the experience offrom 5 to 9 years and increase with the increase in the length of experience of 10 years or more. In the structure of morbidity and TD leading positions are occupied by diseases of the respiratory system, musculoskeletal system and connective tissue, circulatory system and digestive system, diseases of the eye and its appendages. The health damage risk coefficients in the studied groups of workers and the average losses of working time due to the morbidity with TD per 1 employee in all shops are higher than those in the comparison group. The level of the occupational morbidity rate is very low. Harmful working conditions contribute to the development of general and occupationally related diseases.

Introduction. Prevention of chronic general somatic diseases associated with exposure to harmful working conditions is one of the primary measures to preserve the health of the working population and labor resources of the Russian Federation. However, insufficient attention is paid to the management of occupational health risks of agricultural workers, including greenhouse vegetable growers. Materials and methods. Hygienic and epidemiological studies were carried out based on the methodology for assessing and managing occupational health risks. Results. A complex of harmful occupational factors, including high temperatures and humidity, harmful chemicals, including pesticides, plant dust, and the labor process’s severity simultaneously affect working greenhouse growers. Working conditions were assessed as harmful (classes 3.2-3.3) of occupational risk categories from medium to high. Direct statistically significant correlations were established between the length of occupational service and diseases of the respiratory system, circulatory system, musculoskeletal system, and connective tissue (respectively r = 0.58; r = 0.6; r = 0.35). A high degree of causal relationship with the work in harmful occupational conditions of arterial hypertension (RR = 2.805; EF = 64.35%; CI = 1.498-5.253), radiculopathy of the lumbosacral spine (RR = 2.290; EF = 56%; CI = 1.140- 4.599), an average degree of uterine fibroids (RR = 1.969; EF = 49%; CI = 0.988-3.926) and chronic bronchitis (RR = 1.532; EF = 34.7%; CI = 0.682-3.442), which allows classifying them as occupationally conditioned. The system of preventive measures to minimize occupational risks and prevent occupational diseases has been scientifically substantiated. Conclusion. Current working conditions of greenhouse vegetable growers are characterized by the impact of harmful occupational factors promoting occupationally caused diseases, which requires the implementation of a set of preventive measures based on a risk-oriented approach.

Abstract: Relevance. Local vibration is a significant factor in the production environment of metallurgical production, which affects health and efficiency. The aim of the study is to identify the exposure, gender and age features of the formation of general somatic morbidity associated with the impact of local vibration in the production of titanium alloys. Scope and methods. The prevalence of general somatic pathology was compared in 2596 workers who have contact with local vibration, with varying degrees of harmfulness of working conditions, and non-exposed persons according to the results of periodic medical examination using the methodology of occupational risk analysis of the Research Institute of Occupational Medicine. academician N. F. Izmerov. Results. At comparison of prevalence of a somatic pathology at workers in contact to local vibration to not exhibited persons according to medical inspection, and at different degree of harm of working conditions, are revealed the raised risks of formation of diseases nervous, kostno-muscular, endocrine systems, respiratory organs, digestion, an ear, a skin, an arterial hypertensia, the mental frustration, the raised weight of a body, gynecologic diseases with a tendency of growth of the majority of them at the big levels of vibration, more often at small, less often - average degree of communication with working conditions. The frequency of pathology in exposed workers was higher in all age groups. Average degree of communication with working conditions of a gynecologic pathology at the age of 18-25 years was marked. At men frequency of a pathology of respiratory organs, digestion is revealed authentically big, than at women; an ear; skin at the big relative risks 1,2-1,3, of the raised arterial pressure and hyperglycemia. Conclusion. A higher frequency of visceral pathology of a number of body systems under the influence of local vibration of high levels may justify the need to develop differentiated preventive programs to minimize its negative impact, taking into account the identified features in sex and age groups.

The Impact

Vibration pathology, including disorders of the vascular, nervous and musculoskeletal systems, occupies one of the first places in the structure of health disorders in workers of vibration-hazardous industries.The aim of the study was to identify informative diagnostic criteria for identifying early signs of upper limb lesions.The observation group consisted of 90 workers aged 46.7±2.5 years (p>0.05), with experience of 22.4±3.9 years; the comparison group–60 workers whose working conditions were not associated with the studied factor; the average age of 45.8±2.4 years, experience of 24.1±4.1 years (p>0.05). The survey included the analysis of working conditions and professional route, clinical examination, questionnaires, laboratory and functional studies, statistical processing of the results, calculation of epidemiological indicators.The analysis of working conditions showed that the level of local vibration exceeded the maximum permissible level by 2–6 dB for the employees of the observation group. The survey showed that going to the doctor is a last resort for workers, even in the case of chronic pain. According to the results of the survey and examination, it was found that the formation of pain syndrome in employees of the observation group occurs against the background of the development of vascular and neurovascular disorders. There was an increase in the estimated age of the arteries of the upper extremities (5.3±2.8 years) in 23.3% of the observation group. Analysis of dynamometry results in dynamics for three years showed a slowly progressive decline in 21.1% of workers in vibration-hazardous professions with 11.3±3.4 years of experience, and only 3.3% of workers in the comparison group with 23.6±6.3 years of experience. In General, there is a high risk of decreased muscle strength, which is prognostically significant for the preservation of professional ability to work. The calculation of epidemiological indicators confirmed the connection of vasospastic reactions with the impact of local vibration (χ2=5.85, p<0.001; F=0.177, p<0.05; RR=2.5, 95% CI=1.7–3.7; EF=65%). Under the influence of local vibration, early signs of upper limb lesions develop with 5 years of experience and are characterized by vascular changes. Clinical syndromes characteristic of vibrational pathology are formed with an average length of service of 10 years. It is necessary to improve the complex of diagnostic measures aimed at identifying early signs of damage to the upper limbs, in order to improve the labor prognosis in workers under the influence of local vibration.

The prevention of work-related health disorders is a priority in hygiene and preventive medicine. However, little attention has yet been paid to occupational health issues for agricultural workers. The purpose of this research was to assess the current state and develop measures to improve working conditions during the operation of self-propelled combine harvesters, the most widely represented in the existing machine and tractor fleet of agriculture in Russia. Measurements and hygienic assessment of the parameters of the factors of the production environment and the labor process in real production conditions have been carried out. The research results showed that the working conditions on self-propelled combine harvesters are characterized by a complex effect on workers of unfavorable factors (dustiness of the air in the working area, microclimatic discomfort, noise, general and local vibration, physical and sensory-emotional overload), the levels of which to varying degrees exceed hygienic standards. (classes 3.1–3.4). It has been established that the main reason for the formation of harmful working conditions is the operation of morally and physically worn out equipment. It is shown that the impact of an unfavorable production environment can serve as a risk factor for the emergence and development of general and occupational pathology among agricultural machine operators. A set of measures has been developed to ensure safe working conditions and reduce the risk of health disorders for machine operators, including normalizing the microclimate, reducing noise, vibration, dustiness in the air in the working area, optimizing the working posture, and introducing rational modes of work and rest. However, the basic measure that minimizes the adverse impact of professionally determined production factors on the health of agricultural machine operators is the complete replacement of the outdated machine and tractor fleet with agricultural machinery of new generations and compliance with the terms of its operation.

Introduction. Due to the impact of adverse working conditions and climate, workers in coal-mining enterprises in the Arctic are at increased risk of occupational diseases (OD).The aim of the study was to study the working conditions, causes, structure and prevalence of occupational diseases in miners of coal mines in the Arctic.Materials and methods. Th e data of social and hygienic monitoring “Working conditions and occupational morbidity” of the population of Vorkuta and Chukotka Autonomous District in 2007–2017 are studied.Results. It was established that in 2007–2017 years, 2,296 ODs were diagnosed for the first time in 1851 coal mines, mainly in the drifters, clearing face miners, repairmen and machinists of mining excavating machines. Most often, the ODs occurred when exposed to the severity of labor, fibrogenic aerosols and hand-arm vibration. The development of professional pathology in 98% of cases was due to design flaws of machines and mechanisms, as well as imperfections of workplaces and technological processes. Diseases of the musculoskeletal system (36.2%), respiratory organs (28.9%) and nervous system (22.5%) prevailed in the structure of professional pathology of miners of coal mines. Among the three most common nosological forms of OD were radiculopathy (32.1%), chronic bronchitis (27.7%) and mono-polyneuropathy (15.4%). In 2017, coal miners in the Arctic had a professional morbidity rate of 2.82 times higher than the national rates for coal mining.Conclusions. To preserve the health of miners of coal mining enterprises, technical measures to improve working conditions and medical interventions aimed at increasing the body’s resistance to the effects of harmful production and climatic factors are necessary.

Introduction.Methanol and its derivatives occupy one of the leading places among the main organic synthesis intermediates in terms of their importance and scale of production. According to experts, by 2027 the global demand for methanol can reach 135 million tons, the annual growth will be about 5.5%. However, there is little information regarding the assessment of working conditions and occupational risks for workers in modern methanol production and its derivatives.The aim of the studyis hygienic assessment of working conditions and the formation of health risks in workers of modern production of methanol and methylamines.Materials and methods.The assessment of the main adverse factors of production is given. When studying the state of health, objective indicators (the results of an in-depth medical examination) and subjective (the results of a quantitative assessment of the risks of the main pathological syndromes associated with health) are considered.Results.According to long-term observations, the concentration of harmful substances in the air of the working area, indicators of labor severity, parameters of physical factors met hygienic requirements, with the exception of industrial noise exceeding the maximum permissible level, as well as labor intensity of 1 degree. The General assessment of working conditions corresponds to the category of harmful 2 degrees (3.2). According to the results of the medical examination and quantitative assessment of the risks of health disorders in workers, the most significant were functional disorders and diseases of the circulatory system. The levels of somatic pathology on the part of the main body systems were significantly higher in apparatchiks compared to the engineering and technical personnel (ETP).Conclusions:In the production of methyl alcohol and methylamines, the main hygienic importance is the impact on workers of the complex of harmful substances of 1-IV hazard classes in low concentrations, increased levels of industrial noise, labor intensity of 1 degree. According to the subjective assessment of health and medical examination, the greatest prevalence of health risks in workers was observed from the circulatory system, and the levels of the revealed somatic pathology were statistically significantly higher in apparatchiks compared with the ETP.
