Hydraulic, leak or strength tests, internal or external inspections are just some of the operations conducted to verify the reliability of pressure equipment, with the aim of preventing pressure risk. Yet even though these tests appear simple to implement, they[...]
As the first chapter of an accident analysis devoted to industrial automation within the ARIA base, this study examines in detail a selection of 345 accidents involving sensors which occurred within the sectors of Chemicals-Pharmaceuticals, Refining, Food processing and Metallurgy.
Placed directly on the surface of the liquid, the floating roof of a storage tank allows the reduction of emission by evaporation of certain products by the gaseous sky and thus limits the chronic atmospheric pollution generated by the most[...]
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[...]
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[...]
In addition to cases of mixture of incompatible products, assembly errors can also cause many leakages. This can can be due to problems with joints and fittings, in particular due to wrong technical choices or clamping errors. Do not hesitate[...]
Natural gas distribution networks are regularly damaged by public works vehicles during road works in the city. This fact sheet shows the main accident scenarios affecting these structures. Significant accidents, in regard of their human and social consequences or their[...]
Although they are restrictive, power outages in individual homes remain mostly innocuous. On the other hand, in the case of industrial sites, any disruption to the power supply can result in a sudden shutdown of the installations and serious consequences[...]
Whether they are tanks, pipelines or other equipment, whether intensively or punctually used, all of them are liable to lose over time a part of their initial characteristics in terms of operation and safety. The serious confinement losses of Donges[...]
Under standard operation of the installations, the thermal insulation and its protective sheath can complicate the detection of an anomaly, such as the local overheating of a part of equipment, leakage or releaf of chimicals or even of a possible[...]
