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 areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and 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, crafts, 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》第L562-1条将区域划分为两类：风险暴露区域，以及虽未直接面临风险但可采取相关措施以避免风险加剧的区域。依据危险等级的不同，每类区域均需遵循可强制执行的管控要求。
法规通常将区域区分为三类：
1. "禁止建设区域"，即所谓"红色区域"：该区域危险等级较高，通用要求为禁止建设；
2. "法定管控区域"，俗称"蓝色区域"：该区域危险等级为中等，相关项目需遵循适配风险类型的管控要求；
3. 虽未直接面临风险，但各类建设工程、作业项目、开发活动或农场、农业、林业、手工业、商业及工业相关经营活动可能加剧既有风险或引发新风险的区域，该类区域需遵守禁止性规定或管控要求（参见《环境法典》第L562-1条）。
该类区域的适用范围仅涵盖自然RPPs。
