List of Technology Risk Prevention Plans of the Department of Vienna

The Risk Prevention Plans (RPPs) were introduced by the Act of 2 February 1995 on the strengthening of environmental protection. They are the State’s key instrument for risk prevention. Their objective is to control development in areas exposed to major risk.
PPRs are approved by the prefects and generally carried out by the Departmental Directorates of the Territories (DDT). These plans regulate land use or its use through building bans 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 (hazardous, stakes, etc.) may be attached. Each PPR is identified by a polygon that corresponds to the set of municipalities
concerned with the scope of limitation when it is in the prescribed state; and the envelope of the restricted areas when it is in the approved state.
This geographical table allows to map the existing PPRTs on the department.

风险预防计划（Risk Prevention Plans，以下简称RPPs）由1995年2月2日颁布的《加强环境保护法》确立，是国家开展风险预防工作的核心工具，其目标为管控重大风险暴露区域的开发活动。
RPPs由法国省长批准，通常由省领土事务总局（Departmental Directorates of the Territories，缩写DDT）负责落地实施。此类计划通过对现有及新建建筑设定建筑禁令或提出合规要求（涵盖建设规范、脆弱性降低工程、使用限制或农业作业限制等），实现土地用途或开发活动的规范管控。
此类计划可处于三种状态：编制待核准、预实施或已核准。
RPP档案包含说明性文档、管制区划图及管制条例。此外，可附加有助于理解该计划的其他图文资料（如风险分布图、风险受体分布图等）。每份RPP均通过多边形进行标识：当计划处于待核准状态时，该多边形对应受限范围覆盖的全部市镇；当计划处于已核准状态时，则对应受限区域的边界范围。
本地理数据表可用于在省内绘制现有PPRTs的空间分布图。
