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PPRs（PPRs），《环境法典》（Environmental Code）在条款L562-1中划定了两类区域：风险暴露区域，以及虽未直接面临风险但可提前采取措施以避免风险加剧的区域。 依据危险等级的不同，每类区域均需遵守可强制执行的规制要求。相关法规通常将区域划分为三类： 1. 建筑禁止区（又称"红色区域"）：该区域危险等级较高，通用规则为禁止建设活动； 2. 管控区域（又称"蓝色区域"）：该区域危险等级中等，相关工程需符合适配于问题类型的合规要求； 3. 虽未直接面临风险，但建设工程、开发项目或农林、手工业、商业、工业类经营场所等活动可能加剧既有风险或引发新风险的区域，需遵守相关禁止性规定或合规要求（参见《环境法典》条款L562-1）。 该类区域仅适用于自然RPPs（RPPs）。
