Abstract: The reserves of mica raw materials in the country are sufficient to cover all the needs of the industry, but the major part is represented by relatively fine mica, hence high-grade mica is imported in significant quantities. Processed small-sized mica goes to the production of electrical insulating materials. Mica is widely used in electrical insulation operating at elevated temperatures, and is also subjected to heating in preprocessing processes in the manufacture of their products. Over the past years, new mica deposits have been put into development, their applications have changed, and information on the structure and properties has improved. The rapidly growing expansion of the applications of mica products requires an increase in the heat resistance of the materials while maintaining their good processability. In connection with the complex development of natural resources, the use of phlogopite mica and phlogopitic waste is of undeniable interest. The results of modern scientific research show that the heat resistance of phlogopite is 2000 C higher than that of muscovite. This fact opens up the prospect of creating a more durable material. The article considers the working conditions at the enterprise for the creation of electrical insulating heating elements. A description of harmful and hazardous production factors affecting employees in the process of creating heat insulation elements, occupational risks and industrial injuries is given. The conclusion on the specific features of the technological process and on the equipment used was made, and the level of mechanization and automation of the production of mica products as a complex of adverse factors in the production environment was presented. The issues reviewed in the article were rarely raised previously and are little studied.
