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 areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and 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, crafts, 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区域（natural PPRs），《环境法典》（Environmental Code）于第L562-1条中划定了两类区域：风险暴露区域，以及未直接暴露于风险但可采取措施规避风险加剧的区域。
依据危险等级，各区域均需遵循强制性管控要求。该法规通常将区域划分为三类：
1. "禁止建设区域"，俗称"红色区域"，此类区域危险等级较高，原则上实施建设禁令；
2. "管制区域"，亦称"蓝色区域"，危险等级为中等，相关项目需遵循适配问题类型的管控要求；
3. 未直接暴露于风险，但各类建设、工程、开发活动或农、林、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，需遵守相关禁令或管控要求（详见《环境法典》第L562-1条）。
后一类区域仅适用于自然RPP区域（natural RPPs）。
