EU Regulations set the age at which children can handle fireworks at 16, the Spanish government sets the age at 12. The Regional Government of Valencia has lowered that to 8 years of age for certain fireworks on certain occasions. They are referring of course to the Fallas, the Bonfires San Juan fiestas, the fiestas de la Magdalena de Castellón and the festivals of Moros y Cristianos.
What this means is that, at those festivals, young children on the streets can continue throwing fireworks at pedestrians and passing cars without parental supervision or police intervention – madness! To them it is just a game but to the innocent victims it can inflict serious injury.
