The article considers the issue of determining the speed and optimal angle of human movement in a patented sectional type rescue device in case of fires at facilities with a mass presence of citizens, using the basic law of classical mechanics. The physical dependence of the speed of movement of the rescued person on the angle of inclination of the section and the coefficient of friction between the material of the rescue device and the clothing of the rescued person has been established. At the same time, it was revealed that when assessing the compliance of fire rescue equipment from high-altitude levels with the requirements of technical regulations and standardization documents, the issue of determining the optimal angle of movement of people in the rescue device and the safe descent speed is not taken into account, which can lead to unacceptable risks associated with harm to the life and health of citizens.
