On May 29, 2025, at 4 p.m., a test of the operation of the chemical risk sirens is planned, with a Civil Protection alert being sent to the mobile phone, in which citizens will be asked to practice, as a self-protection measure, confinement in a closed space.
Chemical risk sirens will sound in the following municipalities: Tarragona, La Canonja, Reus, Vila-seca, Salou, Constantí, La Pobla de Mafumet, El Morell, Els Pallaresos, Perafort, Vilallonga del Camp.
Your collaboration is requested in terms of monitoring the confinement exercise and, once you receive the alert on your mobile phone, you answer the survey that will appear at the end of the message or that will be available on the same day of the test through the link that we provide below.
Your participation in tests like this is key to improving the functioning of alert systems and strengthening the protection of citizens in situations of chemical risk.
