Constantly improving labor legislation allows working safely and protects the legal rights of employees.

Cardiovascular risk in petrochemical workers

Introduction. The high prevalence of diseases of the circulatory system of workers in various sectors of the economy, the lack of data on the effects of harmful production factors on the formation of cardiovascular diseases in petrochemical industry workers justify the importance of conducting special studies on these petrochemical complex plants with the aim of assessing cardiovascular risk with the subsequent development of preventive measures. Material and methods. The objects of the study were workers in the production of monomers (ethylene, propylene, ethylbenzene, isoprene, divinyl) of petrochemical enterprises. Hygienic studies of the working conditions of workers included an assessment of the factors of the working environment and the labor process using generally accepted methods. Comprehensive clinical examination of workers included periodic examinations (n = 2634) with calculation of total and relative cardiovascular risk using the SCORE system, using questionnaire data, a Reeder L questionnaire and an in-depth clinical diagnostic medical examination (n = 101) with the definition total cardiovascular risk. Results. The most significant occupational factors of the labor process for workers in the main profession - panmen were established to include the combination of a chemical factor with the occupational noise and labor intensity, with an overall assessment of working conditions 3.2. The class of working conditions of workers of the comparison group (locksmith in instrumentation and automation corresponds to the permissible). There were revealed a high prevalence of arterial hypertension and other factors of cardiovascular risk. A higher dependence of the arterial hypertension level on age and length of service in the group of panmen was established when compared to the mechanicians of instrumentation and automation. Using mathematical models of multiple regression, the likely dynamics of the level of arterial hypertension and the left ventricular myocardial mass index were calculated under the influence of increasing age and other risk predictors. Conclusion. The results of a clinical study showed workers with severe arterial hypertension, a high and very high risk of death from cardiovascular disease on the SCORE scale, a high and very high overall cardiovascular risk, signs of dyslipidemia, obesity, high stress levels to require close attention. It is important to timely diagnose lesions of target organs, to conduct rational prevention aimed at reducing risk factors. According to the results of the study, there were developed preventive measures aimed at reducing cardiovascular morbidity and cardiovascular risk, prolonging the longevity of workers in petrochemical industries.

Results of special assessment of working conditions for workers in various sectors of economy of the Republic of Bashkortostan

The work presents data analysis of the results of special assessment of working conditions for workers of various branches of economy in the Bashkortostan Republic. Results of special assessment of working conditions (SAWC) and medical examinations were used for the analysis. It is noted, that some professional groups, for example, persons performing their work in the sphere of agriculture, have no exposure to the biological factor. Construction workers were not exposed to industrial vibration, while the noise level for half of the analyzed cases was of class 2.0, although in most cases, industrial noise and vibration have single source. Proportion of facilities that revealed a discrepancy between levels of harmful industrial factors and requirements of sanitary legislation remains high. The greatest share of objects does not correspond to sanitary and epidemiological requirements according to the chemical and physical factor. At the moment, SAWC does not fully reflect the working conditions of employees in different sectors of production. Underestimation of its influence on working conditions of workers is typical for a considerable number of professional groups and individual jobs. Analysis on the basis of SAWC is not sufficient for a hygienic assessment of the impact of production environment factors and labour process on health and requires comprehensive assessment methods.

Актуальні питання забезпечення безпеки праці шульги

Встановлено, що незважаючи на те, що частка шульг у світі й в Україні зокрема, в наш час зростає, дослідження шляхів адаптації таких людей у суспільному житті обмежується тільки віковою категорією малюки та школярі. З'ясовано, що проблему забезпечення безпеки праці ліворуких людей в Україні не досліджують, а тому такі працівники потерпають від непристосованості умов праці та організації робочого місця відповідно до їхніх фізіологічних потреб. Виявлено, що промисловість у нашій країні і у більшості інших країн не виготовляє технологічного обладнання та інструменту, адаптованого до роботи на ньому робітників-шульг. Виконання роботи ліворукими працівниками засобами праці, що передбачені для праворуких, знижує продуктивність праці та якість виконаної роботи, підвищує рівень ризику виникнення виробничого травматизму та розвитку професійних захворювань. Охарактеризовано основні проблеми, які виникають під час професійної діяльності робітника-шульги у різних галузях промисловості, а також виявлено окремі випадки та види робіт, для виконання яких перевагу необхідно надати саме робітнику-шульзі для підвищення ефективності та безпеки праці. Розглянуто умови праці верстатника меблевої фабрики, шкідливі і небезпечні виробничі чинники, що впливають на його життя і здоров'я та запропоновано загальні рекомендації щодо підвищення безпеки праці верстатників-шульг. Встановлено актуальність подальших досліджень із вирішення проблеми адаптації умов праці до потреб ліворуких працівників у різних галузях промисловості.
