Some industrial processes use retention basins to contain large quantities of sludge or effluents: residues of concentration or transformation of ores, TiO2 manufacture, phosphogypses, fine coal washing ... The combination of volume and nature of the substances retained, their toxic[...]
Repair, maintenance shutdown, adjustment of phase, often require the shutdown and restart of gas-powered installations. This procedure is frequently time consuming to implement, depending on the type of equipment considered (superheater, steam generator), and it can generate accidents. The following[...]
Although the practice of technical feedback seems complex and costly, its contribution to the safety of installations is inestimable: it helps to identify and prevent accidental contexts that could not be detected otherwise. Learning lessons from the past is also[...]
Risk management stakeholders' attention is naturally focused on the identification and reduction of hazard potentials, as well as on technical and organizational measures to reduce the likelihood of accidents. Whatever the effectiveness of the latter, the risk management approach can[...]
Production constraints and technological developments have favored the breakthrough of automated production systems in the industry since the early 1980s. Sometimes these modern systems still coexist with older manual devices which are maintained to allow operation in degraded mode(maintenance, shutdown,[...]
This fact sheet is the analysis of some accidents that illustrate the risks associated with the operation of installations in degraded mode (unavailability of equipment, utility, personnel ...). These degraded operating situations can arise from material failures, but also from[...]
Transmitting the information needed to analyze the situation and the actions to be taken, sensors are essential components for the proper functioning of automated driving and safety systems. Their role is increasingly important in ensuring the safety of industrial sites[...]
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,[...]
In recent decades, companies have developed technical measures to improve the reliability of their installations over time and to prevent industrial risks. Safety management systems were then put in place to ensure the robustness of the whole. Progress has been[...]
The accidentology during phases of work, be it maintenance, modification, installation or even dismantling of installations have been regularly mentioned and studied. This is due to the seriousness of this type of events, particularly in terms of human consequences. Focus[...]
