The dynamics of accidents at enterprises of the transport and road complex and the postal service industry for 5 years is presented. The main events and causes of industrial injuries at the enterprises of the Ministry of infrastructure are considered. It is shown that non-compliance with the requirements of the labor protection instructions accounts for 42 % of all causes of occupational injuries in this area. The coefficients of the frequency of accidents related to production in commercial seaports of Ukraine from 2015 to 2019 are presented. The concept of \"labor protection benchmarking\" is revealed. A list of tasks of labor protection benchmarking at enterprises of the Ministry of infrastructure of Ukraine has been developed, including: identifying weaknesses and strengths of the labor protection management system at enterprises of the Ministry of infrastructure, developing models for rating the level of labor protection; establishing how competitors have succeeded in the field of labor protection; developing organizational and technical measures for labor protection; implementing the best methods of competitors; optimizing and building an effective system of work of the labor protection service; achieving results or at least approaching the results of the reference enterprise of the Ministry of infrastructure. Indicators of information that are necessary for labor protection benchmarking at enterprises of the Ministry of infrastructure are presented.

The aim of the study is to determine the influence of the surface roughness of the printing plate on the deformation of the deckle, as well as on the value of the total force in the area of the printed contact, the relative gear ratio and the relative speed of sliding of the deckle along the surface of the cylinder, which directly affects the dusting of the ink. It was found that when studying the mechanics of a printed pair, the influence of the microgeometry of the contacting surfaces on the parameters under study was not taken into account. The influence of microprotrusions of the surface roughness of the printing plate on the deformation of the deckle in the area of the printed contact has been substantiated and established. To determine the introduction of surface roughness irregularities, a discrete roughness model is used, presented as a set of identical spherical segments. To determine the influence of the surface roughness of the printing plate on the friction force arising in the contact zone, a calculation scheme is proposed that differs from analogs. A method is developed for calculating the parameters of a friction pair in the printing process, taking into account the roughness. Expressions are obtained for determining the total moment of tangential friction forces in the sliding sections when spherical irregularities are introduced. According to the proposed technique, the corresponding graphical dependences of the gear ratio on different parameters of the friction printed pair are shown. The advantages of this study in comparison with analogs are that at certain values of the parameters of the friction pair, taking into account the surface roughness of the printing plate, also at known values of the mechanical characteristics and thickness of the deckle, it is possible to determine the change in the length of the deckle of a given composition, which is necessary in the printing process. The proposed calculation method, which is carried out without taking into account the pressure in the printed contact zone, allows predicting the quality of printed impressions and the amount of ink involved in the formation of ink dusting, as well as correctly adjusting the printing press before the printing process.","PeriodicalId":163233,"journal":{"name":"Labour protection problems in Ukraine","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131294286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studies was based on actual statistical data of the causes and consequences of occupational injuries in mechanical engineering over 12 years. The feasibility of using the method of mathematical modeling based on indicators of injury is justified, since this approach links preventive measures in the field of labor protection with the results of risk assessment and reduces the subjectivity of management decisions. The mathematical model of the labor protection system allows to increase the effectiveness of measures to reduce production risks in mechanical engineering, taking into account the actions or inaction of the employee and the employer, and to optimize the amount of penalties for the employee and employer for violation of labor and production discipline.

To perform the analysis of experimental research data, the method of mathematical planning of the experiment according to the scheme of rotatable central composite planning (RCCP) was used, which is based on regression analysis. The possibility of using for the process of hydroaeroionization of premises where there are people with special needs of saline solutions of different degrees of concentration to increase the concentration of negative ions has been investigated. Analysis of experimental data showed that increasing the concentration of saline solutions leads to a decrease in the intensity of formation of hydroaeroions in the room. Minimizing the mineralization of water will allow you to get the optimal concentration of hydroaeroions with artificial ionization of the room where people with disabilities are. Mathematical processing of the obtained data allowed to establish the combined effect of indoor air velocity (v) and distance to UGA (s) on the concentration of positive and negative aerons when using mineralized water of different degrees of concentration.

The study was carried out at a wide frequency range of the MF action for the researching of dependences to MF technological parameters of the contact welding machine and the distance to it. An induction magnetic field sensor and a digital recording oscilloscope with a fast Fourier transform function were used for experimental studies of MF magnetizing force and their spectral ranges. Based on the analysis of the obtained MF oscillograms and spectrograms, the shape and magnitude of the MF magnetizing force signals in different frequency ranges were established. Since it is impossible to quantify the overall level for a multifrequency MF with taking into account all the harmonic components of the MF simultaneously, the generalized magnetic field level indicator (MFI) was proposed, which became the basis for its use as a methodology for the assessment of MF impact on human body. The use of the proposed methodology allowed to establish that it is generated MF with harmonic components in the frequency ranges 5-50 and 50-1000 Hz at working area under contact spot welding, which may exceed their maximum allowed levels, leading to the respective increase of MFI level. It was established that any changes in the mode of contact spot welding, compared to the mode of welding with one batch of full-phase pulses of welding current, lead to the increase in MFI with exceeding of maximum allowed level at a distance of 800-1000 mm from the axis of contact welding machine electrodes; modelling of the front and trailing edges of the pulse lead to the reduction of MFI level, while increasing the angle of phase control of the heating mode leads to the increase of MFI level. The proposed methodology can be applied as universal both for hygienic assessment of the electromagnetic environment during arc welding and for other electrical equipment. The developed methodology gives possibility to assess the overall impact of multifrequency MF on human body.
