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条将区域划分为两类：风险暴露区域，以及未直接承受风险但可通过预先采取措施避免风险加剧的区域。依据危害等级，每类区域均需遵守可强制执行的管控规范。该法规通常将区域细分为三类： 1. 禁止建设区（俗称"红区"）：此类区域危害等级较高，基本原则为禁止任何建设活动； 2. 特定管制区（俗称"蓝区"）：此类区域危害等级为中等，相关工程需遵循适配于风险类型的管控要求； 3. 未直接承受风险，但各类建设、工程、开发活动或农业、林业、手工业、商业及工业经营活动可能加剧既有风险或引发新风险的区域，需遵守相关禁令或管控要求（参见《环境法典》第L562-1条）。该类区域仅适用于自然RPPs（natural RPPs）。
