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，《环境法典》（Environmental Code）第L562-1条将其划分为两类区域：风险暴露区，以及虽未直接暴露于风险中但需提前制定防控措施以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管控规定。相关法规通常将区域划分为三类：
1. 建筑禁建区，又称“红色区域”：该区域危险等级较高，通用规则为禁止任何建设行为；
2. 管控合规区，又称“蓝色区域”：该区域危险等级为中等，相关工程建设项目需符合针对具体风险类型制定的适配性要求；
3. 非直接受风险影响区域：该区域虽未直接暴露于风险中，但各类建设工程、开发活动或农业、林业、手工业、商业及工业类经营场所（如农场）可能加剧既有风险或引发新风险，因此需遵循相关禁建要求或适配性规定（详见《环境法典》第L562-1条）。

上述第三类区域仅适用于自然RPPs。
