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).

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

It represents the approximate route of the gas pipelines (transport of natural gas).

Identification of the municipalities through which the pipeline passes.

Aeronautical emergency planning zones based on the probability of impact in the vicinity of the airport, aerodrome or heliport. The models used allow the calculation of the probability that, given an accident in the vicinity of an aeronautical installation, the aircraft will impact at a specific point. Two types of zone are defined: Zone I corresponds to the territory with a probability of impact greater than 10% (10e-1) and Zone II corresponds to the territory with a probability of impact greater than 1% (10-2).

Identification of the municipalities through which the gas pipeline passes in the operational phase.

Thematic coverage of the municipalities of Catalonia in which the obligation or recommendation of the municipality to prepare the Municipal Action Plan (PAM) due to wind risk is represented, as well as the current status of the plan.

Thematic coverage of the municipalities of Catalonia in which the municipality's obligation or recommendation to draw up the Municipal Action Plan (PAM) for the risk of snowfall is represented, as well as the plan's current status.

This represents the alert coverage of sirens installed on dams. Some approximations have been made by generating buffers with a predefined coverage radius based on the technical specifications of the sirens, while others have employed acoustic propagation models that incorporate factors such as attenuation, sound dispersion, and the influence of topography.
