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.

针对自然风险预防区域（PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区域，以及虽未直接面临风险但可通过预先制定的措施避免风险加剧的区域。
根据危险等级的不同，每类区域均需遵循具有强制执行力的管控方案。相关法规通常将区域划分为以下三类：
1. 禁止建设区（又称"红色区域"）：该区域危险等级较高，通用规则为禁止一切建设行为；
2. 规划管控区（又称"蓝色区域"）：该区域危险等级为中等，相关工程建设需遵循适配问题类型的管控要求；
3. 非直接风险暴露管控区：该区域虽未直接面临风险，但各类建设工程、开发活动或农林牧渔、手工业、商业及工业业态可能加剧既有风险或引发新的风险，因此需遵循相关禁止性规定或管控要求（参见《环境法典》第L562-1条）。此类区域被称为"天蓝色管控区"，其标识色为天蓝色。
