METHODICAL BASES ON RESEARCH OF OPTIMUM TIME OF WORK OF RESCUERS IN MOUNTAIN CONDITIONS AT VARIOUS LOADINGS AND TEMPERATURES OF INFLUENCE
The purpose of the article is to substantiate the main criteria for developing a method for determining the optimal operating time of mountain rescuers at different loads and temperatures. The analysis of working conditions of mountain rescuers in the spring period is carried out. Experimental studies of the metabolism of rescuers without protective clothing have been carried out. Experimental researches and modeling of influence of intensity of performance of works at ambient temperature in the range +16 - -24ºС are carried out. The dynamics of the process of metabolism of a mountain rescuer during search and rescue operations in a mountainous area has been studied. The temperature regimes of the rescuer's body core under conditions of different load intensity are determined. The energy range of tasks in mountainous terrain for three types of loads is determined. Practical consequences: The built algorithm of research of process of metabolism in mountain area gives the chance to classify conditions of carrying out search and rescue works on degree of difficulty of kinds of works. The obtained indicators of loads, metabolism, intensity of search and rescue operations make it possible to form a basic model for studying the process of rationing the deadlines for tasks. The use of the ANSYS FLUENT software package, refined criteria for assessing the metabolic process allowed to improve the methodology of the model for determining the energy costs of a mountain rescuer in a mountainous area.і Conclusions. The necessity of creating a calculation model for the introduction of sanitary and hygienic requirements for the regulation of safe modes of operation of mountain rescuers is substantiated. The basic factors of the model for further research are determined.
