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

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%).
