Management of Fire-Prevention Distances from the Parking Lot of a Motor Vehicle to the Buildings, Industrial Facilities

The analysis was carried out concerning the regulatory requirements for fire safety aimed at preventing the spread of fire from the parking lot of motor vehicles to various buildings and structures located on the territory of industrial use, as well as an analysis of fires on the motor vehicles. The need is shown related to applying a calculation estimate of the possibility of ignition of a fire-hazardous irradiated material from the effect of a radiated heat flux during a fire for establishing a fire-prevention distance. To assess the fulfillment of fire safety requirements aimed at preventing the spread of fire with the subsequent establishment of a fire-prevention distance from the parking lot of motor vehicles, it is required to implement the calculated scenarios. Scenarios should consider the type (body, opening), the location of the surface (front, rear, side) and its calculated values, the number of motor vehicles, the burning and irradiated materials with their calculated values, the location of the irradiated material relative to the radiating surface (centered, perpendicular, outside zone center). They are based on the mechanism of ignition of the irradiated material from the action of a radiant heat flux during the combustion of a motor vehicle. The practical use of this technique will allow to simulate the threat of propagation of the radiated heat flux to nearby protection objects, to establish a safe distance from the parking of motor vehicles to various buildings and structures for industrial purposes, and to make decisions on the compliance of protection objects with fire safety requirements. To carry out calculations to determine the safe fire-prevention distance from the parking lots of motor vehicles, a computer program was developed for the computer “Assessment of the safe distance from the boundaries of open areas of motor vehicles”. Its practical application will significantly simplify the procedure associated with the assessment of compliance with fire safety requirements aimed at preventing the spread of fire from the parking lot of the motor vehicle to buildings and structures for industrial purposes and will allow to set the value of the safe fire distance between them.
