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（natural PPRs），《环境法典》（Environmental Code）第L562-1条将区域划分为两类：风险暴露区域，以及虽未直接暴露于风险但可采取相关措施以避免风险加剧的区域。依据危险等级，每类区域均需执行强制性管控要求。法规通常将区域分为三类：1. “禁止建设区域”（又称“红色区域”）：该区域危险等级较高，基本原则为禁止建设；2. “规制区域”（又称“蓝色区域”）：该区域危险等级为中等，相关项目需符合适配问题类型的法定要求；3. 虽未直接暴露于风险，但建设、工程、开发活动或农业、林业、手工业、商业及工业经营行为可能加剧既有风险或引发新风险的区域，需遵守相关禁令或特定要求（参见《环境法典》第L562-1条）。该类区域仅适用于自然RPP（natural RPPs）。
