The main features of domino accidents in process/storage plants and in the transportation of hazardous materials were studied through an analysis of 225 accidents involving this effect. Data on these accidents, which occurred after 1961, were taken from several sources. Aspects analyzed included the accident scenario, the type of accident, the materials involved, the causes and consequences and the most common accident sequences. The analysis showed that the most frequent causes are external events (31%) and mechanical failure (29%). Storage areas (35%) and process plants (28%) are by far the most common settings for domino accidents. Eighty-nine per cent of the accidents involved flammable materials, the most frequent of which was LPG. The domino effect sequences were analyzed using relative probability event trees. The most frequent sequences were explosion→fire (27.6%), fire→explosion (27.5%) and fire→fire (17.8%).
通过对 225 起涉及多米诺效应的事故进行分析，研究了过程/储存工厂和危险材料运输中多米诺事故的主要特征。这些事故的数据来自多个来源，发生在 1961 年之后。分析的方面包括事故场景、事故类型、涉及的材料、原因和后果以及最常见的事故序列。分析表明，最常见的原因是外部事件（31%）和机械故障（29%）。储存区（35%）和加工厂（28%）是迄今为止多米诺事故最常见的发生地点。89%的事故涉及易燃材料，其中最常见的是液化石油气。使用相对概率事件树分析了多米诺效应序列。最常见的序列是爆炸→火灾（27.6%）、火灾→爆炸（27.5%）和火灾→火灾（17.8%）。
