The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to monitor development in areas exposed to a major risk.The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through construction prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on use or agricultural practices, etc.).These plans may be under development (prescribed), implemented in advance or approved.The PPR file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPR is identified by a polygon that corresponds to the set of affected municipalities within the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state. This geographical table allows to map existing PPRNs on the department.

风险预防计划（Risk Prevention Plans, PPR）由1995年2月2日颁布的《加强环境保护法案》确立，是国家在风险预防领域的核心治理工具，其目标是对存在重大风险的区域开展开发活动监测。风险预防计划由省长审批，通常由领土事务省级主管部门（Direction Départementale des Territoires, DDT）负责具体执行。该计划通过针对现有或拟建建筑的建设禁令、相关合规要求（包括建设规范、脆弱性消减工程、使用限制或农业生产规范等），对土地利用与开发行为进行规制。风险预防计划可分为三种状态：编制中（待审批）、先行实施以及已获批。每份风险预防计划文件包含编制说明、规制性分区规划文本及配套管制规则，此外可附加其他有助于理解该规划的辅助图文资料（如风险隐患点位、相关议题分析图件等）。每份风险预防计划通过一个多边形矢量图层进行标识：若处于编制待审批状态，该多边形对应规划覆盖范围内的所有受影响市镇的集合；若处于已获批状态，则对应受限区域的边界范围。此地理数据集可用于绘制省内现有风险预防计划的空间分布图谱。
