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 PPRTs the levels of ' hazard are determined effect by effect on maps by type of d’#x27; effects and overall according to an aggregate level on a synthesis map.All hazard zones represented 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 covered by this class of objects but by another standard dealing with the knowledge of hazards.Some areas of the perimeter of #x27;study are considered as “zones of null or insignificant hazard”. It is the areas where the hazard has been studied and is zero. These zones are not included in class d'objects and n'are not to be represented as zones d'aira.
