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》第L562-1条将其划分为两类区域：风险暴露区域，以及未直接暴露于风险但可通过预先采取措施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要求。相关法规通常将区域划分为三种类型： 1. “禁止建设区域”，又称“红色区域”：该区域危险等级较高，通用规则为禁止一切建设活动； 2. “合规管控区域”，又称“蓝色区域”：该区域危险等级中等，建设项目需符合适配风险类型的相关要求； 3. 未直接暴露于风险，但各类建筑工程、作业项目、开发活动、农场经营，以及农业、林业、手工业、商业或工业相关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》第L562-1条）。该类区域仅适用于自然RPPs（natural RPPs）。
