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（natural PPRs），《环境法典（Environmental Code）》在第L562-1条款中划定了两类区域：风险暴露区域，以及未直接暴露于风险但可通过预判性措施避免加剧风险的区域。依据危害等级的不同，每类区域均需遵循可强制执行的管控要求。法规通常将区域划分为以下三类：1. “建筑禁止区”（又称“红色区域”）：该区域危害等级较高，通用规则为禁止建设；2. “指定管控区”（又称“蓝色区域”）：该区域危害等级为中等，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、开发活动或农林牧渔、手工业、商业、工业业态可能加剧既有风险或引发新风险的区域，该类区域需遵循禁止性规定或管控要求（参见《环境法典（Environmental Code）》第L562-1条）。前述第三类区域仅适用于自然RPP（natural RPPs）。
