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（natural 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，以及虽未直接暴露于风险但可采取防控措施避免风险加剧的区域。依据危险等级的不同，每类区域均需遵循可强制执行的管控安排。相关法规通常将区域划分为三类： 1. "禁止建设区"，俗称"红色区域"：此类区域危险等级较高，通用规则为禁止一切建设活动； 2. "特定管控区"，俗称"蓝色区域"：此类区域危险等级中等，建设项目需适配对应风险类型的相关要求； 3. 虽未直接暴露于风险，但各类建设、工程、开发项目或农林、手工艺、商业、工业经营场所可能加剧既有风险或引发新风险的区域，需遵守相关禁令或管控要求（参见《环境法典》L562-1条款）。该类别的适用范围仅涵盖自然RPPs（natural RPPs）。
