For a fire that has never reached flashover or full involvement, the fuel loading and arrangements might be critical to understand. For fires that have become fully involved however, especially if that involvement has lasted more than a few seconds, then fuel loading and arrangements becomes less and less important. Why? Because once flashover occurs the origin of the fuel that is burning is of little importance. By that time, the turbulence associated with these conditions will swirl fuel gases throughout a space regardless of where they were released through pyrolysis. The location that fuel then burns and releases its energy has little to do with its original location but everything to do with where it encounters sufficient oxygen. That is where the energy is released and where burn damage is generated.
