Its activation is reserved for serious emergencies in which the Civil Protection authority must provide immediate instructions: confinement by chemical accidents, episodes of floods or big forest fires, among others.
So far this year, in the Barcelona region, the following have been reported eight notices Through this method: four drills, two under the INFOCAT plan for a fire in Terrassa and two under the INUNCAT plan due to heavy rains, such as Flood risk warning.
