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.

Location of the facilities that appear in the Plaseqcat / Plaseqta and manipulate dangerous substances.

Thematic coverage of the municipalities of Catalonia in which the maximum danger level in relation to the transport of dangerous goods by rail is represented. 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. The danger may come from a section of the railway network that crosses the municipal area or by a section that, without crossing the territory, is at a distance equal to or less than 500 meters from the municipal area.

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).

Distance of 2km radius around each radiological surveillance (IVR) facility. Municipalities within the radius are recommended to draft a municipal action plan for radiological risk.

Municipalities within a distance of 2 km around each radiological surveillance (IVR) facility. Therefore, it is municipalities that are recommended to draft a municipal action plan for radiological risk.

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 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.

Location of radiological surveillance facilities (IVR).

Delimitation of the perimeter of industrial facilities included in Plaseqcat which handle dangerous substances.
