“…It is noting that compared with single flow, the accidental release of superheated liquids involves complex phase change process. For this consideration, the discharge coefficient C d is considered, which was proven to be 0.8 from previous study (Guo et al, 2021). Besides, Table 3 lists the thermo-physical properties of iso-pentane that are used in these equations.…”

“…The average velocity of the uid in the tank is considered negligible compared to the leakage velocity, and the contribution from gravitational potential energy is neglected. The leakage hole is modelled as a converging nozzle, with isentropic and quasi-unidimensional ow (Dutton and Coverdill 1997;Guo et al 2021). By modelling the opening of a leak as a converging nozzle, the instant mass out ow rate (ṁo ut ) can be quanti ed depending on sonic (Eq.…”

Industrial plants are quite susceptible to NaTech disasters during earthquakes caused by damage to structural and non-structural components and the potential release of toxic materials. To mitigate and manage this risk, the ROSSINI project was initiated and its results are described here for what concerns industrial plant worker safety and their risk-based navigation in emergency situations. The project includes a data acquisition system consisting of a data acquisition board and an array of different sensor technologies, which process the seismic event and other meteorological information before passing them as inputs towards the risk identification and evaluation (RIE) modules. Here, the risks associated with structural and non-structural damage and health risks associated with the release of harmful substances are estimated and combined to form a navigable risk map. This map is used within a purpose-built risk-based navigation application for the safe egress of workers from an industrial plant. To demonstrate the implementation of this system, two case-study industrial plant layouts consisting of buildings, non-structural components, liquid storage tanks, piping systems, and chemical storage vessels, were devised. This paper describes the project’s implementation in these contexts and illustrates the results via several example scenarios.
