Assessment of the fire hazard level of buildings (structures) in operation, taking into account the functional fire hazard class for 2017-2020

Abstract

Introduction . The article analyzes the methods of assessing the fire hazard level of operated buildings (structures). The indicator "the proportion of people injured in fires from the total number of people injured in fires" is proposed to assess the fire hazard level of operated buildings (structures). Problem Statement . To assess the fire hazard level of operated buildings (structures), various indicators are used that do not take into account the number of people present at the facility during the fire, but are dependent on this value. The calculation of the indicator "the proportion of people injured in fires from the total number of people injured in fires" as an additional one allows us to estimate the magnitude of fire hazard factors at facilities without taking into account the number of people who were at the protection facility during the fire. Theoretical Part . As the basic information in the study, the statistics of fires and their consequences for 2017-2020 at operated facilities grouped by functional fire hazard classes were used. The indicators used in the calculation are the number of fires, the number of people killed and the number of injured people. Conclusions . The indicator "the proportion of people injured in fires from the total number of people injured in fires" evaluates the probability of survival of people caught in the zone of exposure to fire hazards that lead to injury or death of a person, and characterizes the magnitude of fire hazard factors. Large values of this indicator may indicate a low level of fire hazard — the damage to health does not lead to the death of victims. The calculations of this and other indicators for objects of protection by functional fire hazard classes based on statistical data on fires and their social consequences are given. The high level of fire hazard in single-family residential buildings, agricultural buildings and cultural and leisure institutions is shown.
