Dependence of death and injury of people in fires on the duration of fires

Abstract

Introduction. The effectiveness of the actions of the fire protection units depends on their readiness for action, that is, on the state of the forces and means of the station and the ability to perform the main task within the existing tactical capabilities.Problem Statement. When developing mathematical models of the operational activities of the fire department, its effectiveness and the assessment of the readiness of fire protection units to extinguish fires, it is important to study the dependence of the death of people in fires on the duration of the fire. This study is devoted to this task.Theoretical Part. The distribution of fires in the Russian Federation for 2016-2020 by their duration and the dependence of deaths and injuries of people in fires, as well as their ratio to the duration of fires in the Russian Federation for 2016-2020, is studied. It is shown that the average duration of the fire during the studied period was 26 minutes, the median value of the distribution was 18 minutes. The dependences of deaths and injuries of people in fires on the duration of fires are approximated by a logarithmic function. When the duration of the fire is up to 26 minutes. the ratio of the number of people injured in fires to those killed decreases exponentially, but remains stable in the rest of the time range.Conclusions. It is concluded that it is necessary to increase the readiness of the fire department for actions to extinguish fires and rescue people, which includes the development of an information and analytical model of the operational activities of the fire department.
