According to the sequence of load action, Ding et al. further classified the fireexplosion coupling scenarios into three categories: (1) explosion-fire (Sequential), explosion/fire (Synchronous), (3) fire-explosion (Sequential). They analyzed the hazard-formative mechanism of fire thermal radiation and explosion overpressure from a temporal perspective. An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, which usually travels via shock waves . The negative effects associated with fire usually persist for a long time , and the failure of the target process equipment is a gradual process. On the contrary, the negative effects of explosions are usually brief and sharp. Elastic deformation under overpressure could spring back to its normal shape if the stress does not exceed the elastic limit . Thus, for the fire-explosion coupling scenario (1) and ( ), the coupling effects of fire thermal radiation and explosion overpressure can be ignored.
