Abstract: Krylov V.O. Safety of agricultural production in conditions of application of nitrate mineral fertilizers. - Qualifying scientific work on manuscript rights Work on obtaining a master’s degree in the field of knowledge 26 "Civil security", specialty 263 "Civil security". - Lviv Polytechnic National University of the Ministry of Education and Science of Ukraine, Lviv, 2023. The work is devoted to the development of a complex of peace enterprises to ensure the trouble-free operation of technological equipment, the creation of safe agricultural production in the conditions of the use of nitrate mineral fertilizers, the provision of safe working conditions for service personnel for the production and use of nitrate mineral fertilizers. The physico-chemical and operational properties of nitrate mineral fertilizers, their purpose, and the conditions for the emergence of an emergency situation when working with this type of fertilizer are given. Characterized production of nitrate mineral fertilizers. The following are the provisions of regulatory documents regarding the safe handling of nitrate mineral fertilizers during storage: general requirements for storage facilities; safety requirements when using ammonium nitrate; safe storage conditions; minimum requirements for conveyor transport; requirements for sides and storage mass of ammonium nitrate; ventilation of warehouses. The characteristics of the material flows of the technological process are given. The analysis of technological schemes for the production of encapsulated mineral fertilizers is carried out for the purpose of determining dangerous technological operations. Based on the analysis of the technological process and the properties of substances used in the production of encapsulated mineral fertilizers, dangerous and harmful production factors were determined and their impact on the health of workers was characterized. Worker safety measures against harmful and dangerous production factors have been developed: - protection of the respiratory organs and the mucous membrane of the eyes of employees using dust respirators and protective glasses; - conducting mandatory briefings on labor safety; - maintenance of satisfactory temperature indicators of the working area using thermal insulation of the heater and product tank of the pseudo-liquefied state installation, equipment of the operator’s workplace with supply ventilation; - reduction of the negative impact of noise on the body by using soundproof covers, individual protective equipment; - in order to prevent the negative impact on workers of vapors of organic solvents, it is necessary to equip this workplace with exhaust ventilation; - apply fencing of open rotating parts of technological equipment and installation of warning signs about the dangerous area. Environmental safety measures for the production of encapsulated ammonium nitrate have been developed: two-stage cleaning of aspiration and spent fluidizing air: - rough air cleaning from dust in a cyclone and fine cleaning using a fabric filter; - purification from organic solvent vapor using a periodic adsorber. Key words: agricultural production, encapsulation, nitrate mineral fertilizers, harmful and dangerous factors, industrial safety, labor protection.
