This manuscript shows how the connection and interaction between a process dynamic simulator and a dynamic accident simulator allow improving operators training, accident investigation, and safety management, by better modeling the feedbacks
existing among process units and accidental events. In this perspective, the manuscript presents a rather simplified case study that allows simulating the process dynamic response to an industrial accident comprising a continuous leakage of flammable liquid, the pool spreading, and its final ignition and fire. Interactions between dynamic models of both process and the pool-fire allow
investigating radiative effects on nearby process unit.
