For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of zones: 1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction; 2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs.针对自然PPR区域（natural PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区域，以及未直接面临风险但可采取预防措施以避免风险加剧的区域。依据危险等级的差异，每类区域均需遵循可强制执行的管控方案。相关法规通常将区域划分为三类：1. 禁止建设区域（俗称“红色区域”）：该区域危险等级较高，基本原则为禁止任何建设活动；2. 规管建设区域（俗称“蓝色区域”）：该区域危险等级为中等，建设项目需遵循适配风险类型的管控要求；3. 非直接风险暴露区域：该区域内的建设工程、施工项目、开发活动以及农业、林业、手工业、商业及工业类农场等活动，可能加剧既有风险或引发新的风险，因此需遵守相关禁令或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然RPP区域（natural RPPs）。
