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. Risk prevention plans (RPPs) 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 building prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The RPP file contains a submission 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 mapping existing PPRNs on the department. Each PPRN document existing in the N_DOCUMENT_PPRN geographical table is linked with its GASPAR code in the format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and order number of the associated PPR procedure in GASPAR): 1. its administrative procedure for drawing up (or revising) managed in the GASPAR application, on the one hand, 2. its set of numeric spatial data as described in the metadata sheet N_PPRN_AAAANNNN (#0001495).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工具。其目标是对面临重大风险区域的发展状况进行监测。 风险预防计划（Risk Prevention Plans，RPPs）由省长批准，通常由省级领土事务局（departmental directorates of the territories，DDT）牵头实施。此类计划通过对现有或未来建筑设置建设禁令或提出相关要求（包括建设规范、降低脆弱性工程、农业使用限制或作业方式限制等），对土地利用进行规范与调整。 此类计划可分为法定编制、预实施与已批准三种状态。风险预防计划文件包含提交说明、监管分区规划及监管条例，其他有助于理解该计划制定思路的图文资料（如风险隐患、相关议题等）可作为附件。每份风险预防计划均通过多边形进行标识：处于法定编制状态时，该多边形对应法定范围内受影响的市镇集合；处于已批准状态时，则对应受限区域的整体范围。该地理数据表可用于在省内绘制现有PPRN的空间分布。N_DOCUMENT_PPRN地理数据表中现存的每份PPRN文档，均与其GASPAR代码相关联，该代码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应GASPAR系统中相关风险预防计划流程的参考年份与序号）： 1. 其在GASPAR系统中管理的编制（或修订）行政流程； 2. 其元数据表N_PPRN_AAAANNNN（#0001495）中描述的一组数值空间数据。
