APPLICATION OF NUMERICAL MODELING METHODS FOR SAFETY ASSESSMENT AT PUBLIC FACILITIES
The assessment of safe evacuation of people in case of fires at social facilities in the service sector was carried out on the basis of numerical modeling methods. The time of safe evacuation of people from the object is regulated on the basis of a basic mathematical model for monitoring fire hazards for a specific social object. The dependences of temperature on the duration of the fire, partial density of O2, optical density of smoke, partial density of CO2 and CO, partial density of HCl on the duration of the fire were established with the implementation of the Fogard software package using a simplified analytical model of human flow. On the basis of the developed mathematical model of the development of a fire, design solutions are proposed that provide a secure dispatch of the population from the facility.
