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.

一般而言，受险对象指受灾害威胁、并可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一对象对灾害的敏感程度被称为"易损性（vulnerability）"。
本对象类涵盖了风险预防计划（Risk Prevention Plan，下文简称RPP）研究中涉及的全部相关对象。此处的"对象"为具有明确时间属性的载体，其是否被纳入评估范围取决于RPP的编制目标，以及其对所研究灾害的易损性。因此，是否对RPP相关对象开展评估，需结合当前针对的灾害类型而定。
上述要素构成了在风险对象分析时点，研究区域及其邻近区域开展RPP编制所需的土地覆盖认知基础。
风险对象相关数据是风险预防计划编制阶段形成的、（虽可可视化但并非穷尽的）受灾害影响的资产与个体现状快照。该数据在RPP获批后不再更新，实际也不再被直接沿用：相关风险对象会根据需要采用最新数据源重新计算生成。
