The Ponctual Issue of the PPRT of Calaire Chemie SA

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，受险对象指遭受致灾因子（hazard）威胁、并可能受其影响或损毁的人员、财产、活动、文化或环境遗产要素。某一评估议题针对致灾因子的敏感程度被称为脆弱性（vulnerability）。本对象类别涵盖了风险预防计划（Risk Prevention Plan，缩写RPP）研究中涉及的全部评估议题。评估议题是一类具有时间属性的对象，其是否被纳入考量取决于风险预防计划的目标，以及其针对所研究致灾因子的脆弱性。因此，PPR议题是否被纳入考量，取决于所针对的一种或多种致灾因子类型。在评估议题分析阶段，上述要素构成了研究区域内或邻近区域开展风险预防计划编制所需的土地覆盖（land cover）认知基础。评估议题相关数据展现了风险预防计划编制阶段，暴露于致灾因子下的资产与个体的（figible且非穷尽）快照。该类数据在风险预防计划获批后不再更新。实际应用中这类数据已不再直接使用，评估议题会根据需要使用最新数据源重新计算得出。
