I’d like to ask the experts: how should the affected area of a flow fire within a petrochemical plant be calculated?

I’d like to ask the experts for advice. I’m a newcomer in the chemical industry, and I’m facing a problem: if a piece of equipment, such as a reactor, breaks down under fire conditions and the liquid inside leaks out, how should one calculate the extent of the impact? Or is there any specification that outlines the calculation method? I searched for some information online and found that the diameter of fire circles in China is usually 21.4 meters, but there was no source cited for this figure. I reviewed API521, but was unable to find a suitable calculation method. First, thanks to all the big shotsorz
For this design, including process safety HAZOP analysis, it is necessary to take various factors into comprehensive consideration. Medium, the cause of ignition at the flash point. For reactors, consider container pressure, material, jet fire, and the impact range of explosions. For atmospheric pressure storage tanks, factors such as the tank’s capacity and the size of the tank area enclosure need to be considered.
