Domino effect in process-industry accidents - An inventory of past events and identification of some patterns, Article Journal of Loss Prevention in the Process Industries ; Volume 24, Issue 5 , 2011 , Pages 575-593 ; 09504230 (ISSN) ; Abbasi, T ; Rashtchian, D ; Abbasi, S.

The paper presents an inventory, perhaps the most comprehensive till date, of the major process-industry accidents involving 'domino effect'. The inventory includes, among other relevant information, the sequence of accidents that had occurred in each domino episode. The information has been analyzed to identify several patterns which may be useful in further work on understanding domino effect and reducing the probability of its occurrence in future. A concept of 'local domino effect' has been introduced

A historical survey was performed on 330 accidents involving domino effect, occurred in process/storage plants and in the transportation of hazardous materials; only accidents occurred after 1st-January-1961 have been considered. The main features - geographical location, type of accident, materials involved, origin and causes, consequences, domino sequences - were analyzed, with special consideration to the situation in the developing countries and compared to those from other previous surveys. Among the involved substances, LPG was the most frequent one, followed by liquid hydrocarbons. Process plants (38.5% of cases) and storage areas (33%) were the most common settings; 10.6% of past...

Nowadays the application of decision support systems (DSSs) in process safety is more important than ever. The use of DSS for preventing domino effects is one of the diverse applications of these computer-automated toolkits. Different software packages were developed in recent years, each trying to manage domino risk by a specific approach. In this chapter, the definition, architecture, benefits and essential characteristics of DSS toolkits are described. The application, scope, approach, technical features, advantages, shortcomings and limitations of all the available computerized tools and software packages presented up to now for managing domino effect are then discussed and analyzed...

The uncertainty and the complexity associated with the domino effect is a barrier to assessing the frequency of such accidents analytically. The use of simulation techniques, such as Monte Carlo, to examine the domino effect instead of analytical techniques has shown great promise. In this paper, a new method to assess the frequency of domino accidents is proposed-FREEDOM II-which is an improvement on the recent algorithm proposed by the authors (FREEDOM). The modifications on FREEDOM were carried out to overcome a limitation of the method and to extend its capabilities. A key shortcoming of the earlier method was its inability to handle multiple failure scenarios. This shortcoming has been...

Domino accidents are those which are initiated from one equipment and extend to neighbor equipments or units and as a result the consequence of the primary accident is increased. Risk management is one of the tools for reducing risk of accidents and Quantitative Risk Analysis is a crucial stage in risk management. Despite the importance and severity of domino accidents, in most of QRA studies the effect of these accidents on risk is not considered. In the present work tools for Quantitative Risk Analysis with considering domino accidents has been developed. Two major methods for this reason are used; analytical method and simulation. First, software based on analytical method was developed...

A new methodology is presented with which the likely impact of accident in one process unit of an industry on other process units can be forecast and assessed. The methodology is based on Monte Carlo Simulation and overcomes the limitations of analytical methods, used hitherto, which were inherently limited in their ability to handle the uncertainty and the complexity associated with domino effect phenomena. The methodology has been validated and its applicability has been demonstrated with two case studies
