Catalonia’s civil protection agency Protecció Civil will, on 19 October 2026 at 10 am, test all 119 sirens for chemical risks simultaneously. Before they sound, mobile phones in the affected areas will receive a warning message through the Cell Broadcast system ES-Alert. According to the authorities, 47 municipalities with a total of about 930,000 people will be included; one focus is the Tarragona area, with the industrial clusters Polígon Nord and Polígon Sud. The exercise is expected to last around 20 minutes .
The aim of the test is to check that the acoustic sirens and mobile phone alert system are working properly, and to remind the public how to act in the event of a real chemical accident. In a real emergency, take shelter indoors, close windows and doors, switch off ventilation and wait for official instructions. The authorities have made clear that the alert on 19 October is an exercise; the ES-Alert explicitly says so.
The authorities stress that sirens indicate a mandatory protective measure only when ordered by the incident command. Information should also be provided through alternative channels for people with hearing impairments, such as text messages and notices from local authorities. An anonymous mobile survey is being offered alongside the siren test to gather feedback on how the alerts are perceived and how far they reach.
Organisationally, activating all the sirens simultaneously across Catalonia is a stress test of coordination between Protecció Civil, municipal authorities and emergency and control centres. Any faults identified in individual sirens, transmission routes or the delivery of ES-Alert messages are to be systematically addressed following the review.
The test follows earlier, localised exercises, particularly around Tarragona, where the chemical industry is concentrated. What is new is the simultaneous use of all available systems in Catalonia. For local residents, the exercise means a short-term increase in noise, but it also provides an opportunity to put information chains and emergency guidance into practice.
Protecció Civil says further details about the municipalities affected, sound coverage and specific guidance for vulnerable people are available through its usual information channels at Generalitat de Catalunya . Municipalities are asked to remind local organisations such as schools, care homes and businesses about the exercise scenario in advance.
