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). These zones are referred to as “non-hazardous prescribing zones” and are of sky blue colour.

针对自然PPR，《环境法典（Environmental Code）》在条款L562-1中划定了两类区域：风险暴露区域，以及虽未直接面临风险，但可通过预先采取措施规避风险加剧的区域。
依据危险等级的差异，每类区域均需遵循可强制执行的管控规则。该法规通常将区域划分为三类：
1. “禁止建设区”，又称“红色区域”，该区域危险等级较高，基本原则为禁止一切建设活动；
2. “特定管控区”，又称“蓝色区域”，该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. 虽未直接暴露于风险之中，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可能会加剧既有风险或引发新风险的区域，需遵循相关禁令或管控要求（参见《环境法典》条款L562-1）。此类区域被称为“非危险管控区”，标识色为天蓝色。
