The paper presents the results of experimental studies on the impact of fire protection systems on individual fire risk in buildings. It is shown that the current state of the issue is determined by the lack of scientifically grounded patterns that would quantitatively describe the influence of effective operation of fire protection systems on the parameters of hazardous fire factors and, accordingly, on the calculated values of individual fire risk. A contradiction has been identified between practical approaches to ensuring fire safety and risk assessment methods that do not take into account the effectiveness of technical systems. A program and methodology for an experimental study have been proposed to verify theoretical provisions regarding the influence of fire protection systems on the dynamics of fire development as a derivative of individual fire risk. Criteria and controlled conditions have been defined, namely: temperature, smoke level, response time of the fire protection system, and the time to reach critical values of these criteria for human life. The obtained results made it possible to determine the probability coefficients of effective operation of fire protection systems and to validate the theoretical research. It has been established that the integrated functioning of fire protection systems provides a synergistic effect, reducing the rate of development of hazardous fire factors, extending the time to reach critical values such as temperature and smoke level, and thereby increasing the level of human safety during evacuation, which ultimately affects the value of individual fire risk. The research results were used to improve the methodology for assessing individual fire risk and can be applied in the development of regulatory requirements for equipping facilities with fire protection systems.
