Domino effect accidents are an important process safety issue affecting process plants where significant amounts of hazardous materials are stored, transported, and processed. Losses of containment that result in fires or explosions can escalate to nearby equipment, due to thermal radiation, blast overpressure or other mechanisms, thus ...
A domino effect is the cumulative effect produced when one event sets off a series of similar [1] or related events, a form of chain reaction. The term is an analogy to a falling row of dominoes . It typically refers to a linked sequence of events where the time between successive events is relatively short.
The Swiss cheese model of accident causation is a model used in risk analysis and risk management. It likens human systems to multiple slices of Swiss cheese , which has randomly placed and sized holes in each slice, stacked side by side, in which the risk of a threat becoming a reality is mitigated by the differing layers and types of defenses ...
Heinrich's work is claimed as the basis for the theory of behavior-based safety by some experts of this field, which holds that as many as 95 percent of all workplace accidents are caused by unsafe acts. Heinrich came to this conclusion after reviewing thousands of accident reports completed by supervisors, who generally blamed workers for ...
The accident triangle, also known as Heinrich's triangle or Bird's triangle, is a theory of industrial accident prevention. It shows a relationship between serious accidents, minor accidents and near misses. This idea proposes that if the number of minor accidents is reduced then there will be a corresponding fall in the number of serious ...

Many models to characterize and analyze accidents have been proposed, [10] which can be classified by type. No single model is the sole correct approach. [11] Notable types and models include: [12] Sequential models Domino theory [9] Loss causation model [13] Complex linear models Energy damage model [14] [full citation needed] Time sequence models
