In a metallurgical plant, 2 explosions occurred at 9:30 p.m. followed by a fire in a melting furnace containing 5 t of titanium. The technician on duty was alerted by deviations in control parameters: fusion was stopped by the safety barriers 20 minutes before the explosion and the water level of a tank was lowered. The plant's internal contingency plan was initiated, and the workshop was evacuated. A safety perimeter was established around the building, traffic was interrupted on the D1212 for 2.5 hours, and the gas supply was shut off. The [...]
This ARIA newsflash lists the causes of the various cases of collapse and rupture of silos compiled in the ARIA accidentology database. It reminds the appropriate questions to ask and the guides available to avoid collapses of concrete cells. As the visual checks are not sufficient, the complementary techniques to be considered are also presented.
More and more plants and factories are being automated and the amount of information being transmitted over telecommunication networks is increasing. The general consensus is that there is a risk. However, is it possible to delineate this risk and evaluate its consequences — particularly its environmental consequences — by analysing the events logged in ARIA’s database? For an answer, download this flash.
The accident that occurred in Dieppe, France, on 17 February 2018, reminds us that the process of manufacturing vegetable oil is not without risk.

Due to the goods and products they handle or the nuisances they create, industrial sites have long been the preferred targets for those with malicious intent: 4% of accidents occurring in classified facilities involve malicious intent. In light of this safety threat and given the often significant economic consequences from such aggressions, site operators must exhibit greater vigilance and draw lessons from past events. Malicious intent no longer lies in the realm of imponderable!
