Why are the sirens going off two days in a row in Essonne? Don't panic, it's perfectly normal and expected! Exceptionally, Essonne residents will hear the warning sirens on two consecutive days, December 4 and 5, 2024. This unusual situation is the result of two separate events: the monthly siren test, which takes place every first Wednesday of the month, and a civil protection exercise organized by the prefecture. The latter, scheduled for Thursday December 5, aims to verify the effectiveness of emergency measures, particularly around the Grigny oil site, while raising awareness among the local population.
On Thursday December 5, the exercise will take place at the C.I.M oil site in Grigny. The towns of Grigny, Draveil, Viry-Châtillon and Ris-Orangis are directly concerned, as sirens will be activated to assess their audibility and impact on residents. The main objective is to verify the coordination of emergency services within the framework of the Plan Particulier d'Intervention (PPI), while simulating crisis management at a sensitive industrial facility.
At the same time, the FR-Alert system will also be put to the test. This system will send SMS alerts to residents in the areas concerned, detailing safety instructions. The prefecture specifies that these messages will include the words " EXERCISE " to avoid any confusion. Residents are asked to remain calm, carry on with their normal activities, and not to obstruct emergency lines.
These annual exercises enable the Essonne Prefecture to improve the responsiveness of the emergency services and effectively prepare the population for potential crisis situations. So don't be surprised if you hear the sirens two days in a row: everything is under control.
