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，《环境法典》第L562-1条将相关区域划分为两类：风险暴露区域，以及虽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，每类区域均需遵循可强制执行的处置规则。相关法规通常将区域划分为三类：1. 建筑禁止区域，亦称"红区"，该区域危险等级较高，原则上禁止建设活动；2. 管控区域，亦称"蓝区"，该区域危险等级为中等，相关项目需遵循适配于风险类型的管控要求；3. 虽未直接暴露于风险，但各类建设工程、作业项目、开发活动或农业、林业、手工业、商业及工业经营场所可能加剧既有风险或引发新风险的区域，此类区域需遵循相关禁止或管控要求（参见《环境法典》第L562-1条）。此类区域仅适用于自然RPP。
