Assessment of the parameters of the rapid response of fire and rescue units depending on the time of day

Introduction. The change in the speed of the fire and rescue subdivisions to the place of call, depending on the time of day, is studied. The study is related to the determination of the locations of fire departments. Goals and objectives. The study of the parameters of the rapid response of fire and rescue units was carried out. For cities of the Russian Federation with a population of more than 1 million inhabitants of the Russian Federation for the period 2019-2021, statistical distributions by hours of the day of the number of trips to fires of fire and rescue units, the speed of mobile vehicles, the time of travel to the place of call are constructed. The share of departures for which the arrival time of the first fire and rescue unit exceeds the standard value established by Federal Law of July 22, 2008 No. 123-FZ is determined. Results and discussion. As a result of the study, it was revealed that the maximum value of the speed of following fire and rescue units is observed in the daytime from 10 to 15 hours - 34 km/h, the minimum value is reached at night during the period from 1 to 3 hours - 31 km/h. A study of the parameters of the functioning of fire and rescue units in cities with a population of more than 1 million inhabitants showed that the operational load on fire and rescue units in the daytime increases significantly, which can lead to an adjustment of the plan for attracting forces and resources, when, when a call is received, the guard on duty will be already busy serving another call. These circumstances lead to an increase in the travel time of fire and rescue divisions. As a result, the share of calls for which 123-FZ norms are not met is increasing. The share of such trips during the daytime increases to 18 % versus 8-10 % at night. Conclusions. When determining the locations of fire and rescue units, it is necessary to take into account peak loads that occur during the day.
