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《加强环境保护法》制定，是国家在风险预防领域的核心工具，其目标为对重大风险暴露区域的发展状况开展监测。风险预防计划由省长审批，通常由省领土事务总局（Direction Départementale des Territoires，DDT）牵头实施。此类计划通过对现有或未来建筑实施建设禁令或提出相关要求，规范土地用途与使用行为，具体涵盖建设条款、降脆弱性工程、使用限制或农业生产活动限制等内容。风险预防计划可分为三类状态：处于编制（法定报批）阶段、预实施阶段或获批阶段。风险预防计划文件包含说明性报告、法定分区规划及规制文件，亦可附具有助于理解该方案的其他图文资料（如风险隐患、相关问题等）。每份风险预防计划均以多边形进行标识：处于法定报批阶段时，该多边形对应其规制范围内受影响的所有市镇；处于获批阶段时，则对应受限区域的范围包络线。该地理数据表可用于在全省范围内绘制现有风险预防计划的空间分布图。
