Area exposed to one or more hazards shown on the hazard map used for PPR risk analysis. The map d'random is the result of the study of hazards whose goal is to evaluate the intensity of each hazard at any point in the zone of study. The evaluation method is specific to each type of hazard. It leads to the delimitation of a set of zones on the perimeter d'study constituting a graduated zoning according to the level of l'aira. L' Assignment of'A level of #x27;aira at a given point in the territory takes into account the probability of #x27; occurrence of the dangerous phenomenon and its degree of Â#x27; intensity.For multi-random PPRNs, each zone is usually spotted on the map d'a by a code for each hazard to which it is exposed. All hazard zones shown on the hazard map are included. Areas protected by protective works must be represented (possibly specifically) because they are always considered to be subject to the hazard (case of rupture or d' inadequacy of l’' structure). These source data are not affected by this class of objects but by another standard dealing with the knowledge of hazards.
