Runaway reactions are a major source of industrial accidents. They can occur in a wide array of sectors, including chemicals, petrochemicals, food processing, plastics and rubber manufacturing, and metalworking and are primarily caused by a loss of process control. The processes involved are quite diverse, encompassing chemical reaction, polymerisation and distillation, among others. The loss of process control is related with various factors that are examined in this article. Several accidents that occurred in France and recorded in the ARIA1 [...]
The ARIA database on technological accidents lists 26,271 events in French industrial establishments between 1 January 1992 and 31 December 2016. This large sample allows to give some trends on the exposure of the territories (regions, county) to the industrial risk.
Based on the analysis of 25 000 French industrial events that occurred between 1 January 1992 and 31 December 2015, this document identifies trends over months, weeks, days and hours of accidents
Over the past 3 years, more than 40 fires involving silos containing wood chips or sawdust have been recorded in the ARIA database. In such instances, operational difficulties are commonly encountered by emergency services (lengthy interventions, vulnerability of storage structures, etc.). Each response is therefore unique and requires comprehensive knowledge of all potential risks.
Significant fires are fires that cause damage beyond the unit or equipment causing the accident. This sheet presents the human, social, environmental and economic consequences of these events. Apart from the causes (malicious act, electrical failure, material failure, work by hot spots ...), it is the accumulation of aggravating factors that generates the significant character of a fire. The main aggravating factors are also clarified.
Through the analysis of several singular events, the following fact sheet illustrates the dangers associated with some industrial activities, as for example transportation of flammable materials by pipelines. Moreover, some dangerous phenomena can be caused by domino effects on the surrounding installations. A selection of accidents illustrates this last point.
Explosions following a molten metal / water contact are well-known accidents in the metallurgical industry, which sometimes result in significant human and material consequences. The ARIA database contains some fifty such events implying ferrous and non-ferrous metals melt. The fact sheet to be downloaded presents the specificities of this type of explosion.
The Water Framework Directive of December 2000 which commits the countries of the European Union with a goal of regaining the quality of the water and the aquatic environments by 2015, supposes a better protection of these environments against any type of pollution. In the event of failure of the preventive measures, accidental releases of liquid hydrocarbons may pollute streams, reach underground aquifers, estuaries, coastlines and permanently alter aquatic fauna and flora or threaten the natural resource used for the production of drinking wa [...]
The accidents recorded in the ARIA database involve three main profiles of dangerous phenomena: fires, relief of hazardous materials and explosions. Fire and the relief of hazardous materials are the most frequent accidents. However, the explosions, which are less numerous, represent a considerable potential for destruction. This document seeks to show the interest in knowing more about hazardous phenomena in order to better model them. It also presents the correlations between existing numerical models and events for two real cases of fire and [...]
Many industrial accidents involve work conducted within confined areas, where the primary risk has been generated by the latent or accidental presence of an either flammable, toxic or simply oxygen-deficient atmosphere. The objective of this analysis is to build awareness among actors. It relies upon an analysis of 80 illustrative accidents selected from the ARIA database that involve classified facilities.
