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）是依据1995年2月2日《加强环境保护法》制定的，为国家在风险预防领域的核心规制工具。其目标为监控重大风险暴露区域的发展动态。
PPR由省长批准，通常由领地部门主管局（Departmental Directorates of the Territories，DDT）负责实施。此类计划通过对现有或未来建筑设定建设禁令或提出相关要求（含建设规范、降脆弱性工程、使用限制或农业作业限制等），对土地利用实施规制。
此类计划可分为三种状态：编制中（已下达编制指令）、预先实施及已获批。
PPR文件包含说明性报告、规制性分区规划及监管规程。其他有助于理解该方案的图示文件（如风险源、相关议题等）可作为附件附加。
每份PPR均通过多边形进行标识：当计划处于编制指令状态时，该多边形对应指令范围内受影响的市镇集合；当计划处于获批状态时，则对应受限区域的范围包络线。此地理数据集可用于在省份范围内绘制现有PPR的空间分布图。
