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).

Coverage of the road network affected by the transport of dangerous goods, representing the level of danger of each section in relation to the transport of dangerous goods. The danger level takes into account, apart from the flow of dangerous goods, the type of substances transported.

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

Thematic coverage of the municipalities of Catalonia in which the obligation or recommendation of the municipality to draw up the Specific Municipal Plan (PEM) for emergencies due to episodes of pollution downstream of the Flix reservoir is represented, as well as the current status of the plan

Thematic coverage of the municipalities of Catalonia in which the municipality's obligation to strengthen the Basic Municipal Emergency Plan (PBEM) for the risk of an aeronautical emergency, the reason for this and the plan's current status is represented.

Subzones within zone I or zone of urgent protection measures. It corresponds to the geographic area affected by the passage of the radioactive cloud within a 10 km radius circle around the nuclear power plant (with the nuclear power plant at its center). In the area of ​​zone I, the sector of preferential attention and the zone of preferential attention are also defined.

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).
