Dataset Direct Download Service (WFS): Regulated area of the Technology Risk Prevention Plan (PPRT) around the TOTAL oil depot in Gennevilliers

Risk Prevention Plans (RPPs) are the key government instrument for risk prevention. Their objective is to control development in areas at risk. The development of a risk prevention plan generates a set of spatial data organised into several data sets. The same PPR may include spatial datasets containing: • main PPR encompassing perimeters (study perimeter, prescription perimeter, regulated scope); • restricted areas of the plan once approved. RPP regulations generally distinguish between ‘construction ban areas’, so-called ‘red areas’, where the hazard level is high and where the general rule is the construction ban; ‘areas subject to requirements’, known as ‘blue zones’ where the hazard level is medium and projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions; • hazard areas represented on the map of hazards used for risk analysis by crossing with the stakes, specifying for each zone the level of hazards to which it is exposed; • stakes (persons, property, activities, cultural or environmental heritage elements) threatened by a hazard and likely to be affected or damaged by it; • origins of risk, i.e. the real-world entity which, through its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object that locates the actual entity causing the risk.风险预防计划（Risk Prevention Plans，RPPs）是政府开展风险防控的核心工具，其核心目标为管控风险区域内的开发活动。编制风险预防计划会生成一系列空间数据，并被整合为多个数据集。 单个风险预防计划所包含的空间数据集通常涵盖以下内容： • 涵盖各类边界的主风险预防计划范围，包括研究边界、管控边界与监管范畴； • 计划获批后的受限区域。风险预防计划的管控规则通常会区分两类区域：一是‘禁建区域’，即俗称的‘红色区域’，这类区域风险等级较高，通用规则为禁止建设；二是‘合规管控区域’，也就是‘蓝色区域’，这类区域风险等级为中等，项目需遵循适配问题类型的管控要求，同时还包括未直接暴露于风险但仍受禁令或管控要求约束的区域； • 通过与承险要素叠加开展风险分析的风险地图上标注的风险区域，需明确各区域所面临的风险等级； • 承险要素：指受风险威胁、可能受其影响或损毁的对象，包括人员、资产、活动、文化或环境遗产元素等； • 风险源：即因其存在而构成潜在风险的现实实体。该实体可通过名称、外部对象引用或用于定位实际致险实体的地理对象进行标识。
