Map Viewing Service (WMS) of the dataset: Restricted zone of the PPRT EFR France (ex Delek and BP) in Vitry-sur-Seine (94)

For PPRTs, the environmental code defines a single category of zones for zones (L515-15 et seq.): areas at risk. Unlike natural RPPs, PPRTs never have restricted areas that are not directly exposed to risk.Depending on the hazard level, each TPP area is subject to enforceable regulation. The PPRT regulations generally distinguish between two types of areas:1- “Building prohibited areas”, known as “red zones”, where the hazard level is high and the general rule is the construction ban;2- “prescribed areas”, so-called “blue zones”, where the hazard level is medium and the projects are subject to requirements adapted to the type of issue. The instructions of the PPRT development guide add a gradation within the “red zones” and “blue zones”.针对技术风险预防规划（PPRT），环境编码为（L515-15及后续条款所涵盖的）区域划定了单一类别：风险区域。与自然风险预防规划（RPP）不同，技术风险预防规划（PPRT）不存在未直接暴露于风险中的限制区域。根据风险等级的不同，每个TPP区域均需遵循强制性监管要求。技术风险预防规划的监管规范通常将区域划分为两类： 1. 被称为"红区"的"建筑禁止区域"：该区域风险等级较高，基本原则为建设禁令； 2. 被称为"蓝区"的"指定区域"：该区域风险等级为中等，相关工程需遵循适配问题类型的合规要求。 技术风险预防规划编制指南的相关说明还在"红区"与"蓝区"内部增设了分级细则。
