The purpose of the work – On the basis of natural measurements and laboratory studies, to develop means of protecting workers from harmful effects and a system of organizational and technical measures to reduce production risks Research methods – The scientific and methodological basis of the performed research consists of: the method of instrumental measurements of the shielding coefficients of textile composite materials for protection against the negative influence of electromagnetic fields; grapho-analytical method of determining the effectiveness of shielding textile composite materials. The mathematical dependence of the shielding coefficient on the number of layers of shielding material n and the discreteness of the shielding coefficient F has been established, which makes it possible to determine and predict the shielding coefficient of protective structures based on micro- and nano-sized structures for specific conditions of the production environment using a calculation method. Methodological principles for the production of shielding metal-polymer material on the basis of finely dispersed iron ore dust (5-100 microns), latex and a textile carrier suitable for the production of screens of large areas are proposed. The resulting textile composite material makes it possible to weaken the negative impact of an electromagnetic field of an industrial frequency of 50 Hz with a material thickness of up to 1.5 mm (1 layer) with a shielding substance content of 15.0÷20.0% by 29%, and accordingly, an electromagnetic field with frequencies of 1, 8 GHz by 28% in the production environment.
