For the purposes of Decree 30/2015, the areas affected by the risk of forest fires are defined as the 500 m strip surrounding any forest mass with a surface area of 5 ha or more. This delimitation is used to determine whether a campsite facility falls within the scope of the Decree. If so, it is required to have a self-protection plan.

It represents the municipal qualitative value of the static danger of forest fire from 4 levels and indicating those excluded due to minimum surface area, as well as the municipal qualitative value of vulnerability due to forest fire risk from 5 levels and those excluded due to the absence of 'vulnerable elements.

It defines the maximum intervention zone and alert zone associated with an industrial establishment. If there are a group of industrial establishments located nearby in the territory, the maximum intervention and alert zone will be the total of these types of zones for all establishments in the event that the zones overlap. The intervention zone is the zone in which the consequences of accidents produce a level of damage that justifies the immediate application of protective measures. The alert zone is the zone in which the consequences of accidents cause effects that, although perceptible to the population, do not justify intervention, except for critical population groups. Likewise, in relation to resolution IRP/971/2010, of March 31, which publicizes the criteria for the preparation of reports referring to the control of the implementation of new vulnerable elements compatible with the management of civil protection risks, the maximum intervention zone coincides with the general confinement zone that corresponds to the strip with control of vulnerability and maximum permitted growth with the ultimate objective of allowing the population to be warned and the application of self-protection.

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.

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.

Thematic coverage of the municipalities of Catalonia in which the maximum danger level in relation to the transport of dangerous goods by road mode is represented. The danger level takes into account, apart from the flow of dangerous goods, the type of substances transported. The danger may come from a section of the road 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.

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.

Distance of 1 km radius around each radiological surveillance (IVR) facility. Municipalities within the radius have the obligation to draft a municipal action plan for radiological risk.
