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.

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.

Location of rail network tunnels included within the scope of the PROCICAT action plan for emergencies in the rail passenger transport.

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 an aeronautical emergency is represented, as well as the plan's current status.

Location of alarms to warn the population if there is a chemical risk in the case of an accident in premises nearby.

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

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

Delimitation of the security band with control of compatible vulnerable elements (no residential use and public concurrence, except for compatible industrial uses) based on the zone of limit effects or extremes outside, that is, this area includes the area where the consequences about the population or vulnerable elements are especially significant due to the special intensity of the effects of the emergency.

Polygons which define the range of sound corresponding to the alarms. In accordance with each type of alarm, the sound radius covered can be 800 or 400 metres away from the siren, or maybe unidirectional, covering a distance of 700 m with a 70º opening.
