ANALYSIS OF THE SAFETY AND HEALTH STATUS AT THE WORK OF WORKERS OF THE FOREST INDUSTRY OF UKRAINE AND MEASURES FOR ITS IMPROVEMENT

Development of scientifically sound measures for the prevention of occupational injuries based on the analysis of data on occupational injuries, including fatal in the forestry sector of Ukraine, to identify the main causes of such injuries. Based on the analysis, it was established that the level of occupational injuries in the forest industry was in one of the first places among all sectors of the economy of Ukraine. A step-by-step decision-making process was used to develop an algorithm for making managerial decisions. It was found that the accidents occurred mainly due to violations of safety requirements by employees, lack of control by officials of forest enterprises over the organization of safe work and due to violations of the technological process. The study was based on actual statistics of the State Labor Service on occupational injuries in the forestry sector. It is stated that the situation around the enterprises of the forest industry cannot be radically corrected without the introduction of an effective labor protection management system with elements of assessment and management of industrial risks. The obtained theoretical conclusions, based on statistical data on occupational injuries, have been brought to the level of specific proposals suitable for practical use in the planning of preventive measures for labor protection in the field of forestry. The necessity of actualization and improvement of normative-legal acts in the field of forestry is substantiated. The adoption of the "Minimum requirements for the safety and health of workers in forestry and greenery" is justified, which will expand the scope, namely: legal relations will be regulated by the type of work, and not just apply to economic entities who carry out certain activities; it is proposed to introduce a "labor safety coordinator".

METHODICAL APPROACHES TO IMPROVING THE INFORMATION PROVISION OF OCCUPATIONAL RISK MANAGEMENT

The article presents the results of the analysis of the current state of information support of the labor protection management system in the aspect of transition to the introduction of risk-oriented approach. It is noted that the system of labor protection management, which was formed in accordance with the command-administrative principles of the planned economy, in today's conditions was not effective enough, so it needs to improve its information support. One of the shortcomings of the existing information support of labor protection management can be considered unresolved issues of integration of various information systems (IS) in the field of labor protection, designed to solve management problems, which does not allow to form generalized information bases, to conduct analytical data processing. Assessment of occupational risks requires systematic monitoring of enterprise performance indicators, provides for forecasting the dynamics of changes in these indicators, as well as taking into account other factors that potentially affect occupational risks. To automate the process of collecting and analyzing initial data, modeling and calculating the forecast of occupational risk, it is proposed to create a specialized monitoring information system. Given the need for significant financial costs for the implementation of this project, other approaches to improving information support are the gradual creation of separate subsystems of the monitoring system. The main directions of improvement of information support of occupational risk management are formed, in particular modernization of information systems at the state level and enterprise level is offered. The statistics accumulated during the operation of these systems can be used as initial data for occupational risk assessment and further development of sound preventive measures.

USE OF THE BMP SYSTEM FOR BLOCKING OF DANGEROUS ENERGIES DURING REALIZATION OF WORKS FROM REPAIR AND MAINTENANCE OF TECHNIQUE

Creating healthy and safe working conditions is the main task of the employer when performing high-risk work. Practice shows that the cause of accidents during the repair and maintenance of equipment are uncoordinated and erroneous actions of staff, resulting in incorrect supply of hazardous energy to the installation where people work. In order to prevent injuries at metallurgical enterprises there is a need to revise and modernize the existing approach to control the supply of hazardous energy during repairs, improve the current labeling system of access to repairs of technological equipment based on the experience of advanced world technologies. Audit). The BMP system is used to perform maintenance and repair of equipment, as well as any other cases where personnel need to enter the danger zone, and includes not only the actual process of blocking and marking, but also all other activities: documentation, organization of storage and issuance of BMP devices, training and testing of personnel knowledge According to the analysis, the current tag system at the metallurgical enterprises of Ukraine is inferior in efficiency to the BMP system, which allows you to almost completely eliminate the risks associated with the human factor in the repair and maintenance of equipment. The foreign experience of using hazardous energy blocking and labeling systems and the existing legal framework on this issue in Ukraine are analyzed. According to the results of research, the basic principles of using the BMP system at the enterprises of the metallurgical industry are established. The sequence of BMP procedure implementation is offered. The information on the basis of which the BMP map is formed is considered in detail. An important stage in the formation of this map is the assessment of industrial risks of exposure to hazardous energies in the process of repair and maintenance of equipment. The direction of further research on the implementation of the BMP system and the legalization of the BMP standard at the state level is substantiated.

INFORMATION AND LEGAL COMPONENTS OF LABOR PROTECTION IN THE CONTEXT OF THE COVID-19 PANDEMIC

The article summarizes the state of legal regulation and judicial and law enforcement practice in the field of labor relations, which arise against the background of the COVID-19 pandemic. The normative legal acts referred to by the Ukrainian authorities when making decisions on compulsory vaccination, and which serve as a normative basis for the removal of certain employees from work, are analyzed. At the same time, an analytical review of the decisions of the Supreme Court of Ukraine and the decisions of the European Court of Human Rights on appeals concerning coercion by the authorities and administrative institutions to vaccinate was carried out. Analytical materials of public associations of lawyers and the practice of the Verkhovna Rada Commissioner for Human Rights were also used for analysis. Attention is drawn to gaps in legislation and regulations on the issue of informed patient consent. Certain options for amending the relevant acts are proposed. Conclusions on the instrumental impact of information and legal aspects on the general state of labor protection in a pandemic. The author, in particular, draws attention to the fact that the state, having established the rule that without vaccinations certain categories of workers can not be admitted to work, fulfills its obligation to ensure labor protection. That is, by creating safety and health conditions at work, public authorities and employers protect not only all workers and those who receive their services, but also the person who has not received preventive vaccinations, through the mechanism of offering such an employee, for example, conditions for remote work. At the same time, the article emphasizes the fact that medical institutions and doctors are largely ignoring the provisions of current legislation on the objective information of patients undergoing vaccination. It is about informing patients about the features of different vaccines and the possible consequences of their use. And this, in turn, should lead to the informed consent of the patients themselves. Thus, informed consent in the described legal relations is a specific indicator and, at the same time, an instrument of labor protection. This, in this case, applies not only to subjects who are vaccinated, because then they receive "admission" to the place of work and the work itself, but also, separately, it is a criterion of quality working conditions of health workers, quality of medical services as an independent species. labor. And reaching the level of collective immunity, thanks to mass vaccination, creates a more global protection of the population, and thus, for its working part, and a tool to protect all types of work.

OPTIMISING THE DESIGN PARAMETERS OF A FILTER RESPIRATOR

Purpose. The optimum length choice of the headband insert for a dust filter respirator. Design/methodology/approach. The method of experimental planning has been applied to determine the interpolation (regression) and optimisation dependencies of the filter respirator process. The dominant variables for the respirator were selected based on experimental studies. Input controlled variables for mathematical model are length of tape insertion and headband tension force, output parameter is volume of contaminated air suction under face mask. A regression power relationship between the variables has been established. The recall function was approximated by a second-order non-linear mathematical model. The method of least squares was applied in determining the coefficients at the control variables. Regression dependencies and additional constraints on protective and ergonomic requirements have been used in the optimisation calculations. Conclusions. The solution of the set tasks were the following results: the nonlinear mathematical model more adequately characterizes the respirator use process compared to the linear model of the first order. Relative error between experimental and calculated values of air intake does not exceed 0.6 %. The optimization task is formulated with the regression model. The target function and constraints have been defined with safety and ergonomic requirements. The target function does not have an extremum within the defined constraints. The optimum insertion length was determined graphically and was 2–3.2 cm, the headband tension force does not exceed 5 H With this parameter. Research limitations/consequences. The proposed method is universal in determining the optimum parameters for all types of personal protective equipment. Practical implications: the choice of respirator design parameters can be made using experimentation-surface fitting. Originality/value. The proposed method makes it possible to decline heuristic design methods and establish analytical relationships between the requirements and parameters of individual elements of personal protective equipment.

ASSESSMENT OF THE CONDITION OF THE POLTAVA REGION WATER SUPPLY COMPLEX

Assessment of the state and rationality of the operation of the water management complex (WMC) of the Poltava region is an extremely relevant study of the present, since the WMC was created in the 60s-70s of the last century and actively provides the sectors of the economy and the population with water resources. The study aim is to assess the water resource potential as the basis for the functioning of the water-chemical complex, to determine the levels of technogenic impact on the water resource potential. A review of the sources was carried out using the Google Scholar database by filtering for the period from 2010 to 2021 and mainly revising publications on numerous samples related to monitoring and control of the state of the water management complex of the Poltava region. According to the official report of 2019, the rivers Dnieper, Psel, Sukhoi Omelnik, Uday received an assessment: slightly polluted waters, the Vorskla and Orzhitsa rivers are moderately polluted waters. The main ingredients responsible for the low water ratings as of 2019 are phosphate ions, manganese, as well as nitrite nitrogen, total iron and BOD5. The manganese content was measured in three rivers, and the average estimate ranged from 5.8 in the Psel River to 11.85 in the Vorskla River. According to the Regional Office of Water Resources in the Poltava region, in 2019, 109.8 million m3 were withdrawn from the natural water bodies of the Poltava region, namely underground water bodies, which is 4.6 million m3 less than in 2018 (or 4.0 %), including 69.83 million m3 (which is 3.29 million m3 or 4.5 % less than in 2018). However, the total water intake in the region over the past 10 years has decreased by 2.2 times. A positive trend is that all discharges occur at treatment facilities of housing and communal services. There is no discharge of return water without treatment into surface water bodies of the Poltava region; however, within the boundaries of settlements there is a discharge of under-treated municipal wastewater and runoff from the urbanized territory. Consequently, balancing water use is possible by introducing waterless, low-water and water-saving technologies in all sectors of the economy, maximum use of water in recycling water supply systems; replacement of physically and morally worn out water supply and water protection equipment, etc.

SCIENTIFIC GUIDELINES FOR THE PREVENTION OF OCCUPATIONAL INJURIES CAUSED BY WORKERS STAYING AT THE WORKPLACE IN A STATE OF ALCOHOLIC DRINKING

Development of scientifically based measures for the prevention of occupational injuries due to alcohol intoxication of workers are based on modeling of the labor protection system. In order to develop effective preventive measures to prevent accidents at work, the mathematical model of the labor protection system (OS) was built, which takes into account many indicators that assess violations of labor and industrial discipline related to alcohol consumption. The study was based on actual statistics on occupational injuries. The application of the method of mathematical modeling on the basis of injury indicators is justified, as the proposed approach allows to ensure the targeting of preventive measures, the complexity and alternative solutions to problems, the objectivity of management decisions. The proposed scientific approaches to the development of preventive measures for labor protection allow to increase the level of industrial safety, optimize the size of penalties for violations of labor and industrial discipline, regulate relations arising in the course of work related to alcohol consumption in the workplace. Limitations / implications of research. The developed scientific approaches to the prevention of occupational injuries due to alcohol intoxication of workers are universal, they can be applied to different sectors of the economy. Practical consequences. The obtained theoretical conclusions, based on statistical data on occupational injuries, are brought to the level of specific proposals suitable for practical use in the planning of preventive measures for labor protection at enterprises. The presented scientific approaches to solving management problems in labor protection are based on a component method of assessing the occurrence of traumatic events due to violations of labor and production discipline by both employees and employers. For a comprehensive analysis of industrial risks, the main and concomitant causes that led to accidents due to alcohol intoxication of workers were taken into account. This allowed to provide a systematic approach to the assessment of production conditions and behavioral reactions of staff.

MODELING OF STABILITY OF SIDE ROCKS IN A COAL MASIFWITH DIFFERENT METHODS OF SUPPORT THE WORKINGS

Purpose of work. Determine the conditions of the side rocks stability in a coal massif with different ways of support coal-rock stratum to ensure safe working conditions for miners in the excavation areas of a coal mine with steep coal seams. To achieve this goal, laboratory studies were carried out on models of optical and equivalent materials. The modeling of the stability of side rocks in a coal-rock massif was carried out with the methods of support roadways with vertical timber setsand wooden crib supports: 4-point chock.On models made of optical materials in the analysis of the static field of the distribution of shear stresses in side rocks, the regularity of the change in hazardous manifestations of rock pressure, depending on the deformability of support structures, was recorded. On equivalent models of support structures, the deformation characteristics of experimental samples were determined and their effect on the integrity of the roof under the action of static loads was established. When using rigid support structures in the form of vertical timber sets made of wooden racks to protect sliding drifts, there is a deterioration in the stability of side rocks and destruction of the roof. When using flexible support structures in the form of wooden crib supports: 4-point chock, a smooth deflection of the roof and its integrity are observed. A decrease in the size of the stress concentration zone in the model of a coal-rock massif with workings after the compaction of flexible support structures located above the haul roadway, due to a change in their rigidity, when as a result of the convergence of side rocks, a smooth deflection is provided and the movement of the roof is limited. To ensure the stability of side rocks and development workings, as well as reduce the level of injuries of miners from landslides and collapses in the excavation areas of coal mines that develop steep seams, it is advisable to use flexible support structures, when using which, a smooth deflection of side rocks and their integrity in the mined-out area is ensured coal massif.

REMOVAL OF POTENTIALLY TOXIC METALS FROM AQUEOUS SOLUTION USING TETRA PAK INDUSTRIAL WASTE AS BIOSORBENTS

Potentially toxic metals (PTMs) contamination in the water bodies had been a worldwide challenge. Industrialization and anthropogenic activities have produce and discharge wastes comprising organic and inorganic pollutants into the water resources making them hazardous and threatening human health and the environment. Packaging technology for food and beverages such as juices, milk, and other liquids using paper packets, generally known as Tetra Pak, has resulted in the generation of too much waste in the world in recent decades. On the one hand, it appears that the building of composites from Tetra Pak trash allows for maximum recycling of these materials, while on the other hand, the inclusion of Kraft paper, Al, and polyethylene in the packet composition can improve the functional features of the goods. Tetra pak packaging is comprised of three different types of raw materials: cellulose (75 %), low density polyethylene (LDPE) (20 %), and aluminium (5 %).The present research aimed to assess the potential of Tetra Pak industrial waste as biosorbents to remove PTMs such as lead (Pb), Nickle (Ni), and Copper (Cu) from PTMs-artificial contaminated water. Approximately, 0.05 mg/L concentration for Ni, 0.027 mg/L for Pb, and 0.05 mg/L for Cu were artificially added in the water bodied to assess the adsorption efficacy amended with two samples of waste Tetra Pak OTP (sample product1) and DOTP (sample product 2) as biosorbents. The obtained results showed that the maximum Ni adsorption recovery was received by (83 % with DOTP), Pb 52 % with OTP and Cu 32 % with OTP as bio-sorbent amendments. Overall, the present study indicated that the remove of PTMs from dilute aqueous solutions and using industrial waste material as easily available and low-cost sorbent, that can be successfully used to remove pollutants from multi-metal polluted water.
