A new IT-Alert test will be held today, November 28: after Umbria and Veneto, the public alarm system will be tested in Lombardy for the specific risk of a “significant industrial accident”, involving the Bracco Imaging SpA plant in Ceriano Laghetto (MB). At 09:00, all devices within 3 km of the plant, subject to the Seveso Directive, will receive a message.
The objective of these simulations is to verify the correct functioning of the system, identifying the parameters to be optimized to improve its effectiveness.
As always, the test will include sending text and sound notifications to all cell phones connected to cell phones in the affected areas, even in the absence of an internet connection. At the moment, the national public warning system, officially active since 2024, is still being tested for three specific risks: tsunamis, volcanic activity of Stromboli and intense rainfall.
Where and when the IT-Alert test sounds in Lombardy
The test on 28 November 2025 will involve part of the province of Monza Brianza, in Lombardy: the specific risk simulated is that of a “significant industrial accident”. In particular, the calendar includes:
09:00 – IT-Alert test, simulated major industrial accident at the Bracco Imaging SpA plant in Ceriano Laghetto (MB), a plant subject to the Seveso Directive.
The text contained in the pop-up, sent to anyone within a 3 km radius of the plant, will be the following:
TEST TEST IT-alert test message. A SIMULATION of an accident is underway in an industrial plant in the area where you are located. To find out the message you will receive in case of real danger and to fill out the questionnaire go to www.it-alert.gov.it TEST TEST
What to do when the alarm message arrives on your cell phone
The simulation in Lombardy consists of sending a text notification and an audible alarm to all smartphones turned on and connected to the cells covering the areas affected by the specific risks being simulated. Since this is a test, once you receive the simulation message you will not have to do anything: the IT-Alert system, in fact, does not provide for interaction with the messages.
However, the citizens involved will be able to choose to fill out an official (non-mandatory) questionnaire to provide feedback on the functioning of the system, communicate whether the alert has been received or not and ensure the efficiency of communication flows in the future.
