This dataset contains the geographical location of sirens installed on dams, designed to act as an alert system in the event of a dam or dike breach. The installation points have been determined based on acoustic dispersion models and an analysis of flood-prone areas with resident populations, aiming to optimize coverage and ensure immediate notification to the people living in these areas.

Identification of the municipalities through which the ethylene pipeline passes.

Identification of the municipalities through which the pipeline passes.

It represents the time of avenue or arrival of the floods from sectorizations of the fluvial courses.

It represents the areas susceptible to triggering avalanches and their extent, based on geomorphological criteria and the French model "Carte de Localisation des Phénomènes d'Avalanche" (CLPA).

It represents the areas of winter observation of avalanches.

Seismic intensity (MSK scale) that can be expected for a return period of 500 years

Municipalities that within their territory have a nuclear installation, different from a nuclear power plant. Municipalities with large ports or airports with a significant flow of radioactive goods are also included.

Location of rail network tunnels included within the scope of the PROCICAT action plan for emergencies in the rail passenger transport.

The ZIF (defenceless zone) is defined as the minimum security zone necessary to guarantee the viability of self-protection of vulnerable elements in the context of an accident in the transport of dangerous goods. The extension of this zone is conditioned by the necessary response time and the intensity of the effects of foreseeable accidents. The distances of the ZIF for the scenarios of long-range toxic cloud, short-range toxic cloud, serious explosion, flammable cloud and puddle fire are established in "The Technical Instruction of the DGPC regarding the preparation of reports on the conditions minimum requirements that new urban developments must comply with to be located within the identified chemical risk zones due to the transport of dangerous goods by road and rail" (ITMMPP).
