    The paper is devoting to researching of properties of materials for protection of the person from harmful factors. The issue of protecting people from the influence of external harmful factors to date is very relevant. There are a number of factors, constitutes a threat to the human health in the process of life. The nature of the dangerous influence on the person of external factors is quite diverse by nature of origin, the nature of interaction with the organism and the consequences that cause the action of harmful factors. For protect against the influence of dangerous harmful factors, personal protective equipment is used, the leading place among which is the special protective clothing. When designing protective clothing, important to investigate the properties of materials, as well as the impact of the processes of clothing use on the properties of these materials. The analysis of harmful factors and the study of general properties of protective materials was carried out by analytical and observation methods. Investigation of the influence of operation factors on the change of the properties of textile materials for protective clothing was carried out by experimental method (for the experiment, a tear-off machine of the brand RT-250 was used). The scientific novelty determined by the influences of the washing process on the values of bursting and elongation during the rupture of materials for the manufacture of protective clothing (fabric CORDURA NIR and CORDURA MK, jersey Cool- Max). Based on the results of the study, the authors conclude that the wet processing improves the bursting characteristics of the materials being studied. At the same time, the authors emphasize the need for a comprehensive study of the quality indicators of the materials in question in order to fully determine their protective properties. In the conclusions, the authors suggest the use of investigated fabrics for the manufacture of protective clothing for protection against mechanical damage, and also indicate that the jersey under study does not lose the strength characteristics during washing. Research materials can be used to improve the design of clothing protective special.

    ПРОЄКТУВАННЯ ЖИЛЕТІВ РОЗВАНТАЖУВАЛЬНИХ ДЛЯ ІНСПЕКТОРІВ-КРИМІНАЛІСТІВ. DESIGN OF VEST UNLOADING FOR INSPECTORS-CRIMINALISTS
    (2019) Александров, М.Є.; Aleksandrov, M.Ye.; Дмитрук, В.А.; Dmytruk, V.A.
    Research article highlights the peculiarities of the design and unloading vests for inspectors-criminalists. At the moment, criminals use mainly suitcases for transportation, storage and use of technical tools of forensic examination, which have a significant mass, which, in turn, creates inconveniences in the conduct of investigative and operational activities. For the rational placement of technical and forensic tools and distribution of their weight on the human body, it is advisable to develop unloading vest of inspectors-criminalist, which will be equipped with a belt bag, the design of which will be adapted to modern technical and forensic tools. For the design of the vest and belt bags, it is advisable to investigate the dangerous harmful factors acting on criminalist during their activities, as well as the requirements for rational placement and use of technical and forensic tools. The analysis of the conditions for the activities of inspectors-criminalists, the determination of the list of dangerous harmful factors acting on a person and his equipment, events of a different nature were carried out by an analytical method, a method of observation and questioning. Development of requirements for the design of the vest and its individual elements was carried out by the methods of observation, comparison and experimentally. The scientific novelty consists in the classification compiled by the authors, regarding dangerous hazardous factors that influence the work of the inspector- criminalist, as well as in determining the minimum required set of belt bags for the placement of technical and forensic means of maiden necessity. Based on the results of the study, an experimental sample of the unloading vest was developed, as well as a set of summaries for technical and forensic means. The developed sample of the unloading vest for criminalists, besides the optimal distribution of the load of technical and forensic tools on the human body, also provides the convenience of using various types of tools, protection from contamination prevention and mechanical damage, as well as from traffic accidents during the inspection of the accident scene on the highway. With these matters cleared away, in conclusions the authors emphasize the need for experimental testing of the developed prototype example to the vest of unloading inspector-criminalist to determine further directions for its improvement.
