Domino effect accident
Domino effect accident is an accident in which a primary undesired event in an installation sequentially or simultaneously triggers one or more secondary undesired events in nearby installations, leading to secondary and even higher-order accidents, resulting in the overall consequences more severe than those of the primary event. Due to the escalation of accidents, domino effect accident is indeed a chain of accidents. The entire accident escalation process is similar to the mechanical effect of a falling row of dominoes, so it is called a domino effect accident or Knock-on accident. Domino effect accidents are an important safety issue in the process industry in which a lot of hazardous materials are stored, transported, and processed via storage tanks, pipes and process facilities, etc. These hazardous materials may induce poisoning, fire, and explosion when a loss of containment occurs. Fire and explosion within an installation may escalate to other installations by hazardous physical effects such as heat radiation, overpressure, and fragments, etc.
