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

Municipalities within a distance of 1 km around each radiological surveillance facility (IVR). Therefore, municipalities are obliged to draw up a municipal action plan for radiological risk.

Location of radiological surveillance facilities (IVR).

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.

Thematic coverage of the municipalities of Catalonia in which the obligation of the municipality to prepare the Basic Municipal Emergency Plan (PBEM) is represented due to the risk of emergency in passenger rail transport, the reason for this and the state of validity of the plan.

Municipalities that within their territorial scope have facilities attached to the radiological surveillance protocol.

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 railway 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. The average data on the transport of dangerous goods from the last four years has been used with the aim of obtaining more stable data over time and minimizing the current variations derived from the socioeconomic context of each specific year.
