Generally speaking, the stakes are people, property, activities, cultural or environmental heritage elements, threatened by a hazard and likely to be affected or damaged by it. The sensitivity of an issue to a hazard is called “vulnerability”. This object class brings together all the issues that have been addressed in the RPP study. An issue is a dated object whose consideration depends on the purpose of the RPP and its vulnerability to the hazards studied. A PPR issue can therefore be considered (or not) depending on the type or types of hazard being addressed. These elements form the basis of knowledge of the land cover necessary for the development of the RPP, in or near the study area, at the time of the analysis of the issues. The data on issues represent a (figible and non-exhaustive) photograph of assets and individuals exposed to hazards at the time of the development of the risk prevention plan. This data is not updated after approval of the RPP. In practice they are no longer used: the issues are recalculated as necessary with up-to-date data sources.概言之，风险受险对象涵盖人员、资产、各类活动以及文化或环境遗产元素，它们受灾害威胁并可能因此遭受影响或损毁。某一对象对灾害的敏感程度被称为“脆弱性（vulnerability）”。 该对象类别整合了风险预防计划（RPP, Risk Prevention Plan）研究中涉及的全部研究对象。此处的“研究对象”指具备时间属性的实体，其是否被纳入考量取决于风险预防计划的目标，以及其针对所研究灾害的脆弱性。因此，PPR研究对象是否被纳入评估，需根据所应对的灾害类型而定。 在开展研究对象分析的阶段，上述要素构成了在研究区域及其周边区域制定风险预防计划所需的土地覆被认知基础。 研究对象相关数据是风险预防计划制定阶段，受灾害威胁的资产与人员的（可视且非全覆盖）快照。该数据在风险预防计划获批后不再更新。实际应用中此类数据已不再直接使用：研究对象会根据实际需求，采用最新数据源重新计算生成。
