Mining dust as a health threat to employees of extraction departments of coal mines

Occupational diseases arising in the area of the Ministry of Defence in the Czech Republic and their relationship to work categorization.

The article deals with occupational health protection and identification of health risks in the work environment of the Ministry of Defence (MoD) of the Czech Republic (CR). It focuses on the assessment of the incidence of occupational diseases (OD) in high-risk and risk-free occupational categories in the years 2010-2019 and compares them with data from the civilian sector. It identifies the differences between military staff and civilian employees of the MoD. From the records of OD at the Department of Occupational Diseases of the Central Military Hospital in Prague, the data on acknowledged OD from the years 2010 to 2019 were obtained and then a retrospective analysis focusing on the classification of work at risk was performed. The obtained data were compared with the data from the Czech National Registry of Occupational Diseases (NROD), which are published annually by the National Institute of Public Health. In the years under review, 191 OD were confirmed at the area of MoD, 26% of all OD occurred in employees classified in the occupational risk category. Compared with the data in the NROD, where 50% of OD were found to have been caused by high-risk work, the incidence of OD caused by high-risk work in professional soldiers is lower. Only 1.6% of all OD occurred in professional soldiers whose work was classified as high-risk one. In civilian employees of MoD 24.6% of all OD were connected with high-risk work. On the contrary, the proportion of OD occurring in professional soldiers working in risk-free categories was 57.6%, in civilian employees of MoD was the ratio much lower - 16.2%. Work at the Ministry of Defence was not adequately categorized, therefore, in 2020 a new categorization of work was introduced, which together with preventive measures could contribute to reducing the incidence of OD at the Ministry of Defence.

Динамика профессиональной заболеваемости в субъектах Северо-Западного федерального округа Российской Федерации в 2011–2020 годов

The aim of this paper was to analyse a 10-year dynamics of occupational disease incidence in 8 entities of the Northwestern Federal District (NWFD) of the Russian Federation. Materials and Methods. The authors used data on occupational disease incidence from the Federal Statistical Survey (form no. 24) of the Federal State Statistics Service (FSSS). Results. It is shown that in 2020 in the NWFD, 37.3 % of the total number of employees worked under harmful and/or hazardous working conditions, which is comparable to the national data. However, in some entities of the NWFD this indicator significantly exceeded the district’s average: in the Arkhangelsk (55.1 %), Vologda (50.1 %) and Murmansk (48.8 %) Regions. Noteworthy, during the period from 2011 to 2020, the NWFD as a whole saw a positive trend towards reducing the percentage of workplaces failing to meet the sanitary standard requirements for noise, vibration, illumination and microclimate. It should be emphasized that over the past 10 years, the NWFD has seen a moderate downward trend (coefficient of determination = 5.3) in the number of patients with newly diagnosed occupational diseases per 100,000 able-bodied population, while the nationwide indicator has followed a strong downward trend (R2 = 9.0). At the same time, in three entities (Komi Republic, Murmansk Region, and Republic of Karelia) this indicator was higher than the average for the NWFD. Thus, in spite of the general positive trend towards reduction in the number of workplaces failing to meet the sanitary standard requirements and towards a decrease in occupational disease incidence during the 10-year period in the NWFD as a whole, some of its entities need to further optimize the working conditions and increase workers’ functional reserves to maintain the health of the able-bodied population.

Structural Equation Modeling using Partial Least Squares for Occupational Safety and Health Factors and Work Environment Factors Toward Occupational Diseases on Labors in Industry X Cimahi City

Occupational diseases can be caused by work, work tools, materials, processes, or the work environment. Efforts to control risk factors during the production process in the manufacturing industry are important. These efforts are carried out by monitoring and measuring the work environment for environmental prevention and management. Technical control, administrative control, and the use of personal protective equipment (PPE) are some efforts to maintain their health condition and protect workers from health problems and adverse effects caused by work. This study wants to figure out the modeling of occupational safety and health factors, individuals, and the work environment that can cause occupational diseases in workers by using Partial Least Square Structural Equation Modeling (PLS-SEM). The sample size in this study was 50 workers (respondents). The analysis used is Chi-Square and PLS-SEM. The results showed a significant relationship between the PPE use, years of service, air dust levels, illness history, and noise factor with the incidence of occupational diseases. In conclusion, there is a significant relationship between occupational safety and health factors (PPE use and noise factor) with occupational diseases, between individual factors (years of service and illness history) with occupational diseases, and between work environment factors (air dust levels) and occupational diseases. In suggestion, a control over workplace environmental parameters that exceeded the threshold value is required, such as dust, noise, lighting, temperature, and humidity levels. Further research on other risk factors that can affect the incidence of occupational diseases is required, such as gas parameters, ventilation, and the application of occupational safety and health management systems.

Trends in Occupational Infectious Diseases in South Korea and Classification of Industries According to the Risk of Biological Hazards Using K-Means Clustering.

Against the backdrop of the COVID-19 pandemic, it is necessary to identify these risks and determine whether the current level of management is appropriate to respond to the risk of biological hazards depending on the occupation. In this study, the incidence and fatality rates of occupational diseases were calculated using industrial accident statistics of South Korea, and trends by year using joinpoint regression and relative risk by industry using k-means clustering were evaluated for infectious diseases. We found that infectious diseases had the third highest incidence and fourth highest fatalities among all occupational diseases. In the incidence rate, joinpoints appeared in 2009 and 2018, and the annual percent change changed to 7.79, −16.63, and 82.11. The fatality rate showed a consistent increase with an annual percent change of 4.37, but it was not significant. Industries were classified into five groups according to risk, and the legal control measures of certain industries were not sufficient. Follow-up studies are needed to rectify the structural limitations of industrial accident statistics.

Metabolomics for exposure assessment and toxicity effects of occupational pollutants: current status and future perspectives.

Work-related exposures to harmful agents or factors are associated with an increase in incidence of occupational diseases. These exposures often represent a complex mixture of different stressors, challenging the ability to delineate the mechanisms and risk factors underlying exposure-disease relationships. The use of omics measurement approaches that enable characterization of biological marker patterns provide internal indicators of molecular alterations, which could be used to identify bioeffects following exposure to a toxicant. Metabolomics is the comprehensive analysis of small molecule present in biological samples, and allows identification of potential modes of action and altered pathways by systematic measurement of metabolites. The aim of this study is to review the application of metabolomics studies for use in occupational health, with a focus on applying metabolomics for exposure monitoring and its relationship to occupational diseases. PubMed, Web of Science, Embase and Scopus electronic databases were systematically searched for relevant studies published up to 2021. Most of reviewed studies included worker populations exposed to heavy metals such as As, Cd, Pb, Cr, Ni, Mn and organic compounds such as tetrachlorodibenzo-p-dioxin, trichloroethylene, polyfluoroalkyl, acrylamide, polyvinyl chloride. Occupational exposures were associated with changes in metabolites and pathways, and provided novel insight into the relationship between exposure and disease outcomes. The reviewed studies demonstrate that metabolomics provides a powerful ability to identify metabolic phenotypes and bioeffect of occupational exposures. Continued application to worker populations has the potential to enable characterization of thousands of chemical signals in biological samples, which could lead to discovery of new biomarkers of exposure for chemicals, identify possible toxicological mechanisms, and improved understanding of biological effects increasing disease risk associated with occupational exposure.

The Extent of Occupational Health Hazard Impact on Workers: Documentary Evidence from National Occupational Disease Statistics and Selected South African Companies’ Voluntary Corporate Social Responsibility Disclosures

This paper explores the potential of Corporate Social Responsibility disclosures in providing alternative information on the extent of occupational health hazard impact on workers, by selected South African companies operating within the manufacturing and utilities sectors amidst an absent national occupational disease surveillance system. An online internet search was used to retrieve publicly available national occupational disease statistics published between 2001 and 2020, and Corporate Social Responsibility reports of selected South African case companies, published between 2015 and 2020. Content analysis was used to analyse the retrieved documents for both descriptive and numeric data. The collection and reporting of occupational disease data in South Africa is inconsistent. Corporate Social Responsibility disclosures related to occupational health metrics vary between companies. Occupational disease incidence was the least reported of the social aspects in Corporate Social Responsibility disclosures, and/or were reported as a single statistic or combined into occupational safety incidence rates in some instances, obfuscating the true extent of the impact caused by occupational health hazards on workers. Furthermore, noise-induced hearing loss remains the most prevalently reported occupational disease, in general. Corporate Social Responsibility reports point to occupational health hazards requiring regulatory intervention, whilst also providing an alternative information source for occupational disease statistics.

Analysis on incidence of occupational diseases in Guangzhou from 2010 to 2020

Objective: To analyze the incidence characteristics of occupational diseases in Guangzhou from 2010 to 2020, provide scientific basis for formulating occupational disease prevention and control policies. Methods: In January 2021, based on the data of occupational diseases in Guangzhou reported in the Information Monitoring System of Occupational Diseases and Occupational Health, descriptive epidemiological method was used to analyze the types and characteristics of occupational diseases in Guangzhou from 2010 to 2020. Results: A total of 1341 cases of 38 kinds of occupational diseases in 9 categories were reported in the past 11 years. The incidence of occupational pneumoconiosis, occupational otolaryngology and oral diseases and occupational chemical poisoning ranked the top three, accounting for 38.1% (511/1341) , 30.5% (409/1341) and 16.2% (217/1341) of the total cases respectively. The cases of pneumoconiosis in welders and silicosis accounted for 47.7% (244/511) and 34.4% (176/511) of the cases of occupational pneumoconiosis respectively. The cases of noise deafness accounted for 99.8% (408/409) of occupational otorhinolaryngology oral diseases. Acute occupational chemical poisoning cases accounted for 26.7% (58/217) of the occupational chemical poisoning cases, in which dichloroethane poisoning cases ranked the first, accounting for 79.3% (46/58) . Chronic occupational chemical poisoning cases accounted for 73.3% (159/217) of the occupational poisoning cases, in which benzene and lead poisoning cases ranked the top two, accounting for 79.2% (126/159) and 17.6% (28/159) respectively. Conclusion: Pneumoconiosis, silicosis, noise deafness, benzene poisoning, lead poisoning, dichloroethane poisoning should be supervised and managed as key occupational diseases in Guangzhou.

Epidemiology, clinical and physiological manifestations of dust lung disease in major industrial centers

BackgroundThe present study aims to determine the structure of morbidity in workers contacting industrial aerosols, assess the timeliness of diagnosing dust-induced lung disease in major industrial centers, and optimize diagnostics for early detection of occupational lung diseases in workers exposed to industrial dust hazards.MethodsThe study on the structure and incidence of occupational lung diseases was carried out in 2016–2020 based on the Moscow Centre for Occupational Pathology data. For a more in-depth clinical examination, 114 patients who were first admitted to the Occupational Pathology Centre with diagnosed pneumoconiosis (PC), chronic dust-induced bronchitis (CDB), and chronic obstructive pulmonary disease (COPD) were selected. All patients were subjected to a complex clinical-functional, spirographic, echocardiographic, fibroscopic, radiological, and CT lung examination, with subsequent analysis of the results obtained. The pathology caused by exposure to industrial aerosols within the studied period was first diagnosed in 344 workers. Most patients (64%) with newly detected pathologies were 50–59 years of age, with work experience in adverse conditions of 21–25 years (41%).ResultsThe spirographic study of respiratory function revealed decreased forced vital capacity (FVC) indices in CDB and COPD patients. Changes in expiratory flow rates suggest occupational bronchitis at an earlier stage, whereas no apparent results were noted for the PC diagnosis. The results of fibroscopic examination in PC patients revealed atrophic processes of the bronchial mucosa in 46 (88.5%) of them, and 6 (11.5%) patients had a subtropic process. The results of echocardiographic examination allowed diagnosing pulmonary heart disease in 83 patients (72.8%). Of them, 42 (80.8%) were revealed in the group of patients with PC, 18 (50.0%) in the COB group, and 14 (53.8%) in the COPD group.ConclusionsComputed tomography (CT) detected pathological changes in 52 patients, while the X-ray examination in six people showed no evidence of lung destruction. CT scan also showed that the number of patients with fibrotic PC (including silicosis) in the study groups increased. Timely clinical and functional examination (spirography, fibroscopy, echocardiography) of patients allows detecting PC (including silicosis), CDB, and COPD at an early stage of disease progression.

The effect of subcontractor status on occupational injury and disease incidence: a cross-sectional study using the 9th Occupational Safety and Health Company Survey.

Despite the efforts of contractors to identify and reduce any occupational risk that exists in subcontracted works, if the associated risks cannot be eliminated and reduced and subcontractors have to take risks, this situation can be called 'risk transfer.' The hypothesis of this study is that the contractor-subcontractor status of a company affects the risk of occupational injury or occupational disease. The inside subcontractor and outside subcontractor represent subcontractors located inside and outside the contractor workplace, respectively. The dataset from the 9th Occupational Safety and Health Company Survey (OSHCS) with 5219 workplaces, which was conducted in South Korea, was used. After the exclusion of 45 workplaces with no reported employees, 5174 workplaces with a total of 1,072,583 employees were used for analysis. Poisson regression was applied with the contractor-subcontractor category as the independent variable and the number of both occupational injury and disease cases per workplace as the dependent variable. Poisson regression is an appropriate model for the count-data analysis of rare events that do not follow a normal distribution but rather follow a right-skewed distribution. Compared to the 'contractor' category, the 'outside contractor' reported the highest risk ratio, 1.66 (95% Confidence Interval, CI 1.09-2.41). The 'inside contractor' reported the second highest risk ratio, 1.39 (95% CI 1.07-1.78). In contrast, the 'both contractor and subcontractor' category reported a statistically significant decreased risk ratio of 0.69 (95% CI 0.57-0.84). The 'neither contractor nor subcontractor' category showed a statistically equivocal risk ratio of 0.91 (95% CI 0.76-1.07). This study confirmed the increased risk of occupational injuries and diseases for subcontractors, whether located inside or outside the contractor workplace (1.66-fold and 1.39-fold increased risk, respectively). Future individual-based epidemiologic studies such as case-control and cohort studies could provide more detailed information such as specific risk factors associated with subcontracted works and confounders according to industry classification.

Objective: To analyze the pattern and characteristics of occupational diseases in Weihai City from 2009 to 2020, and to provide scientific basis for the formulation of occupational disease prevention. Methods: In February 2021, retrospective analysis was performed on the cases of occupational diseases diagnosed from 2009 to 2020 in Weihai City. The relevant information and data were collected to analyze the types of occupational diseases, onset age, working age, diagnosis time, industry distribution, economic type and enterprise size distribution. Results: From 2009 to 2020, a total of 453 cases of new occupational diseases were reported in Weihai City. There were 431 males (95.14%) and 22 females (4.86%) . The average onset age was (49.16±8.51) years, and the average working age was (17.89±9.30) years. The incidence of pneumoconiosis and other respiratory diseases (322 cases, 71.08%) , occupational otolaryngology and oral diseases (71 cases, 15.67%) and occupational chemical poisoning (36 cases, 7.95%) were the top 3 cases, of which 313 cases were pneumoconiosis and 69 cases were noise deafness. The cases were mainly concentrated in the 40-59 years age group (357 cases, 78.81%) and the 10-19 years working age group (175 cases, 38.63%) . There were significant differences in the incidence of occupational diseases in different ages and different working ages (χ(2)=97.64, 80.74, P<0.001) . The new cases were mainly in mining industry (134 cases, 29.58%) , shipbuilding or maintenance industry (97 cases, 21.41%) , and private enterprises (350 cases, 77.26%) . Conclusion: Pneumoconiosis and noise deafness are the main emerging occupational diseases in Weihai City. Occupational disease prevention and control in private enterprises such as mining and shipbuilding or maintenance industry should be strengthened.

The implications of organizational environment questionnaire for the assessment of occupational injury among medical workers

Organization environment has significant influence on occupational health among medical workers. In current study, based on previous established questionnaires, we constructed a new questionnaire to evaluate the effects of organizational environment on occupational injury of medical workers. In a large-scale of investigation, a total of 2350 medical workers from 54 hospitals in Zhuhai city, China, were surveyed by the new questionnaire, and 2111 (91.2%) questionnaires were used for final analysis. The average score of organization environment of medical workers questionnaire was 91.33 ± 21.95. We found that as compared with the average levels, medical workers have higher incidences of behavioral symptoms such as depressed mood, obsessional thinking, and anxiety and so on. We also demonstrated the questionnaire scores correlated with the incidence of occupational disease, occupational injuries and the scores of SCL-90, implying its potential application to objectively measure the conditions of medial safety of medical workers in China. In all, we concluded that organizational environment has important implications on the assessment of occupational health of medical workers.

Lack of workplace risk assessment as a predictor of adverse health effects for teleworkers - results from the survey on Life with COVID-19 in Latvia

Workplace risk assessment is one of the key tools for improving occupational safety and health conditions. However, providing risk assessment for teleworkplaces in the COVID-19 pandemic-related restrictions has been a challenge for employers. The objective of this study was to identify the frequency of implementation of workplace risk assessment for teleworkplaces and the association between it and self-reported health complaints among teleworkers during the 1st emergency state of the COVID-19 pandemic in Latvia. Teleworkers were recruited using a non-probability sampling (snowball sampling) method and social media advertisements. To obtain data that is representative of the demographic profile of the working population in Latvia, the sample was weighed based on gender and age. Out of 447 teleworking respondents included in our analysis, only 20.3% have mentioned that their employer had assessed the teleworking conditions (additional 8.1% reported partial assessment). Workers who have reported lack of risk assessment more often have health related complaints – e.g., pain longer than three days (26.9% with risk assessment versus 73.1% with no risk assessment), sore eyes (24.4% versus 75.6%) and anxiety (21.8% versus 78.2%) (p &lt; 0.001 in all cases, except for pain). Increased incidence of occupational musculoskeletal diseases and burnout can be predicted in coming years in Latvia. Good practise examples should be gathered and promoted; guidelines for labour inspection should be developed in order to cover supervision of teleworking workplaces.

Objective: To analyze the characteristics of occupational diseases in Bao'an District of Shenzhen from 2006 to 2019, so as to provide scientific basis for formulating occupational disease prevention policies and measures. Methods: In September 2020, the information of new occupational disease cases in Bao'an District of Shenzhen from 2006 to 2019 was collected through the national occupational disease and occupational health information monitoring system, and the classification, disease type distribution, population distribution and industry and enterprise scale distribution of new occupational disease cases were analyzed. Results: From 2006 to 2019, a total of 762 new occupational diseases were reported in Bao'an District of Shenzhen, of which the top three were occupational ear, nose, throat and oral diseases (233 cases, accounting for 30.58%) , occupational chemical poisoning diseases (219 cases, accounting for 28.74%) , occupational pneumoconiosis and other respiratory diseases (127 cases, accounting for 16.67%) . The classification composition of occupational diseases was different in different years, and the difference was statistically significant (P<0.05) . New occupational diseases are mainly distributed in the manufacturing industry (394 Eaterprises, caccouling 93.59%) , concentrated in (346 cases, accounting for 47.66%) and medium-sized enterprises (199 cases, accounting for 27.4%) small enterprises. Conclusion: New occupational diseases in Bao'an District of Shenzhen should focus on small and medium-sized manufacturing enterprises, carry out risk assessment of occupational hazards, implement classified and hierarchical supervision of occupational health, and implement occupational health protection.

Occupational Disease as the Bane of Workers' Lives: A Study of Its Incidence in Slovakia. Part 2.

The main objective of this article is to monitor the development of the number of occupational diseases related to selected physical factors in the working environment (noise, vibration and dust). Each region of Slovakia has its own specific social and economic conditions. Due to the existence of a strong correlation between the several regional variables observed, principal component analysis (PCA) was used to determine the new variables. Cluster analysis was used to group regions with similar characteristics. A dendrogram was created using the average linkage method, which illustrated the similarity of the regions studied. The value of the cophenetic correlation coefficient (CC = 0.90) confirms the validity of the average linkage method. The result of the cluster analysis is the grouping of the eight regions into five homogenic groups (clusters). An analysis of the data shows that Slovakia’s regional differences significantly influence the incidence of occupational diseases in individual regions. It is shown that, in Slovakia, the development of the number of occupational diseases has seen a favourable trend in the long term.

DIETARY GUIDELINES FOR PROTECTION OF THE OCCUPATIONAL HEALTH OF WORKERS IN FORESTRY

Introduction: Healthy and safe working conditions in the Bulgarian forest economy are associated with a lower incidence of labor abuses and occupational diseases among forest workers. Strategic management in this area includes actions to improve the working environment, part of which is the organization of pre-occupational nutrition. Purpose of the study is to support the occupational health of forest workers with specific dietary guidelines. Methods: The object of the study is 105 workers employed in the forestry of Northern Bulgaria. A documentary method was used - a study of the medical documentation from preventive examinations conducted in the period from 2015 to 2019. The results were analyzed with statistical software SPSS v.20. Results: Dietary recommendations in forestry aim to reduce the occupational health risk from contact with biological hazards, cold and hot microclimate, noise, dust and forced working posture. Dietary guidelines include adequate hydration, recommended eating frequency with a mandatory snacks, consumption of animal foods, fruits and vegetables, which increase the intake of essential amino acids, dietary fiber, vitamins (A, C, B1, B2, B6,), calcium, magnesium and trace elements, limiting the intake of saturated fatty acids and sodium, provision of dining facilities, clean food and clean drinking water. The training of forest workers to regulate energy intake is also being discussed. Conclusion: The implementation of dietary recommendations based on leading occupational hazards in forestry will help to protect occupational health and safety at work.

Violation of medical statistics as one of the reasons for the low incidence of occupational diseases

Many authors point to the low incidence of occupational diseases in our country. The reasons are poor-quality preventive examinations, the lack of interest of employers in identifying these diseases, and others. However, there are no works in the literature devoted to errors in the statistical coding of diagnoses of occupational pathology and their accounting. The study aims to improve the accounting of occupational diseases in Russia. We conducted the study using the information base of the Industry Register of Persons with Occupational Diseases, developed by Burnazyan State Medical Center of the FMBA, Russia, which operating in the industry since 2011. As of 31.12.2020, the register contains information on 2,056 patients with occupational diseases, from among the employees of enterprises and organizations served by healthcare institutions of the FMBA, Russia. Errors of incorrect coding of diagnoses for occupational diseases with violation of the classification principles in the used directive materials played a negative role. The development of plans for medical and social rehabilitation measures to reduce the incidence of occupational diseases among the people working in harmful conditions. It requires correct knowledge of morbidity indicators of this nosology. In order to improve the accounting of occupational diseases in Russia, it is necessary to switch to the system of coding diagnoses of this nosology, adopted in medical statistics, and make appropriate changes to the directive documents.

Сравнительная характеристика условий труда работников и состояние профессиональной заболеваемости в Республике Башкортостан

Background : Improvement of working conditions at enterprises of various sectors of economy can be achieved by solving comprehensive organizational, social, legal and other tasks. The purpose of the research was to study working conditions and occupational morbidity of workers of various industries in the Republic of Bashkortostan in 2000–2019. Materials and methods : We analyzed working conditions of the population employed at the enterprises of the republic and occupational disease rates. Results : Most occupational risk factors were attributed to imperfection of technological processes, equipment and design flaws of machines, mechanisms, equipment, devices and tools. More than a third of cases of occupational disorders were diseases of the musculoskeletal system while every fifth case was that of a respiratory disease; radiculopathy and vibration disease prevailed among nosological forms. Men exposed to general vibration were most at risk of developing occupational diseases, including those induced by other occupational risk factors. At enterprises of mining, construction, and manufacturing industry, working conditions usually failed to meet sanitary and hygienic requirements for physical work heaviness, noise and chemical exposures, in agriculture – for physical work heaviness, and in transport and communications – for work heaviness and intensity. Conclusion : We observed a steady increase in the proportion of employees exposed to occupational risk factors and/or hazards and a simultaneous decrease in registered occupational disease incidence rates.

Assessment of the working conditions under exposed to noise and infrason

Currently in healthcare of the Russian Federation created a system of measures to combat the harmful effects of industrial noise on workers. However, the level of specific and nonspecific morbidity rates the effect of industrial noise is not reduced, and the incidence of occupational diseases tends to increase. This is due to several reasons, including a large number of sources of noise, not enough high quality of medical examinations, lack of and low effectiveness of means of individual protection from noise and others. Noise is one of the leading places among the harmful physical factors in the Armed forces of the Russian Federation. Features noise resulting from the operation of military equipment and armament is its high intensity, intermittent nature, the presence in the spectrum of low and infrasonic frequencies. Noise exposure leads to the development of diseases, primarily of the organ of hearing, increase in total morbidity and the reduction of military-professional health. In the normative documents of the military medical service the noise is not identified as a harmful factor leading to the development of occupational diseases that were not fully developed the issues of professional selection and medical examination of noise pathology. System noise control should be comprehensive and include organizational and technical measures, special assessment of working conditions, monitoring of noise sources, the presence and correct application of means of protection against noise professional selection, clinical monitoring, medical examination, treatment and preventive measures. Existing in the Armed forces of the Russian Federation the system of measures for the fight against harmful impact of noise on military personnel requires revision in accordance with the existing state legislative framework.
