    Stanovenie teploty vznietenia sena pre účely posudzovania rizík v stredných a malých poľnohospodárskych podnikoch
    (University of Zilina, 2022) Marková, Iveta; Giertlová, Zuzana; Hutár, Marek
    Hot surfaces are an integral part of the technological processes of agricultural crop processing. Hot surfaces' temperature, at critical points, may exceed their minimum ignition temperature. The article aims to experimentally monitor the behaviour of hay in the event of its exposure to radiant heat. The mentioned model is implemented using a hot-plate device. The hot plate has a defined temperature-time curve. Based on the temperature-time curve, the hot surface´s temperature is determined as the minimum ignition temperature of the examined hay sample. At the same time, the temperatures inside the tested material were monitored. The heterogeneity of these samples significantly affected the nature of thermal degradation of biomass samples. The hay ignition temperature (406 ° C) can serve as a tool to assess the risk of fire.

    Ukážka spolupráce katedry požiarneho inžinierstva so závodným hasičským útvarom ZAHAS Žiar nad Hronom pri realizácií praktického cvičenia
    (University of Zilina, 2022) Rečlo, Rudolf; Marková, Iveta
    Thanks to long-term cooperation between the Department of Fire Engineering with Industrial Fire Department ZAHAS in Žiar nad Hronom under the lead of JUDr. Marián Šmida, an exercise for the development of practical skills regarding firefighting equipment was conducted. Students of first-year master's degree studies, students of third-year bachelor's degree studies and three Erasmus programme students from France attended the exercise. During the practical exercise, students acquired knowledge of the equipment of water tender CAS 32 Tatra 815, extinguishing the fire using a powder handheld fire extinguisher, preparation of hoseline, working with a combined nozzle and vehicle-mounted nozzle.
