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

It represents the areas of winter observation of avalanches.

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

Thematic coverage of the municipalities of Catalonia in which the obligation or recommendation of the municipality to draw up the Municipal Action Plan (PAM) for chemical risk in the transport of dangerous goods by road and rail is represented, as well as the current status of the plan

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.

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.

It indicates whether or not the municipality exceeds any of the thresholds established as a criterion to determine whether it is obliged or recommended to draw up the Municipal Action Plan for seismic emergencies. In order to establish the obligation to draw up the action manual for municipal seismic emergencies, there are two criteria: exceeding the intensity threshold in this case greater than or equal to VII, or for exceeding reference damage, in this case case more than 50 uninhabitable buildings or more than 10% of the total uninhabitable buildings in the municipality. Municipalities that appear in white mean that they do not exceed these thresholds.

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).

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.

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.
