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区域（PPRs），《环境法典》依据L562-1条款划定了两类区域：风险暴露区域，以及未直接面临风险但可采取相关措施规避风险加剧的区域。
根据危害等级的不同，每类区域均需遵守可强制执行的建设管控规则。相关法规通常将区域划分为三种类型：
1. “禁止建设区”，又称“红色区域”：该区域危害等级较高，通用规则为禁止一切建设行为；
2. “限定建设区”，又称“蓝色区域”：该区域危害等级中等，建设项目需遵循适配问题类型的相关要求；
3. 未直接面临风险，但各类建设、工程、开发活动或农场（农业、林业、手工业、商业或工业类）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管控要求（详见《环境法典》第L562-1条）。该类区域的适用范围仅局限于自然RPP区域（RPPs）。
