The study of multi-hazard coupling disasters involves various challenges. One of the toughest challenges is analyzing the interactions between incidents, known as "synergic effects." As its research object, this paper takes multi-hazard coupling disasters involving fire, explosions, and toxicant leaks in hazardous chemicals scenarios. It aims to qu...
A domino accident is a typical multi-hazard coupling disaster in the chemical industry that often has serious consequences and social impact. The quantitative risk assessment of domino accidents faces several difficulties caused by their complexity, unpredictability, and synergic effects. This paper proposes a new method for quantitative risk asses...
Multi‐hazard coupling disasters, in which multiple hazards occur simultaneously and interact to compound the consequences, are a common phenomenon. The assessment of the individual risk in multi‐hazard coupling disasters faces several difficulties due to the nonlinear additivity of risks from multiple hazards. This article presents the Choquet inte...
Multi-hazard accidents in process industries, which can cause more severe consequences compared to individual accidents, have gained growing attention from administrators and scholars in recent years. With the development of process industries and the expansion of the urban area, high-risk zones may emerge in densely populated areas. Accurate risk...
Fire environments impose severe effects on the human body through thermal radiation, smoke particles, and toxic gases. This review focuses on human injury mechanisms including human thermoregulation, heat strains, skin injuries, and inhalation injuries in fire environments. Human thermal models and their coupling system with CFD and thermal sweatin...
An emergency platform is an informatization support platform for disaster information perception, disaster situational awareness, and emergency decision command. This is a key tool for ensuring the efficiency and effectiveness of emergency responses. Numerous large countries have conducted in-depth research on the key technologies of emergency plat...
Due to the effect of industrial agglomeration, chemical clusters have become the development tendency of chemical industry. However, the benefits coexist with the risk of accidents in chemical clusters. The quantitative risk assessment of chemical clusters faces two challenges. First, the synergistic effects in chemical clusters introduce nonlinear...
One of the challenges of the multi-hazard coupling risk assessment is synergistic effects. This research performed experiments and numerical simulations, aiming to analyse the synergistic effects on the physical effects of explosions. The direct influences of atmospheric temperature and density on the propagation of explosion shock waves were expla...
The risk assessment of chemical clusters faces two challenges. First, the synergistic effects in chemical accidents introduce nonlinearity into the risk. The second challenge is the lack of cooperation and information exchange. A novel method for risk assessment in chemical clusters with the application of a Choquet integral and a multiple linear r...
In order to reduce the casualties and property losses caused by the chemical accidents related to hazardous chemicals, the chemical domino accidents were taken as the research object to explore the chain reaction mechanism and risk assessment methods of one or more secondary accidents caused by the initial accident. A method of applying Monte Carlo...
With the development of disaster-risk research, it has been found that many areas are prone to the simultaneous occurrence of natural disasters and technological accidents. Such events are known as “multi-hazard.” Increasing attention has been paid to multi-hazard risk, and the theory and methods of multi-hazard risk analysis have been put forward...
