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.针对自然污染风险防范区域 (PPRs)，《环境法典》第L562-1条将其划分为两类区域：风险暴露区域，以及虽未直接面临风险但可通过预先制定防范措施以避免风险加剧的区域。 依据危险等级的不同，每类区域均需遵守可强制执行的管控规则。相关法规通常将区域划分为以下三类： 1. 建筑禁止区域（又称「红色区域」）：该区域危险等级较高，原则上严禁开展任何建设活动； 2. 规划管控区域（又称「蓝色区域」）：该区域危险等级为中等，相关建设项目需遵循适配问题类型的管控要求； 3. 虽未直接面临风险，但各类建设工程、施工项目、开发活动或农、林、手工业、商业及工业类经营场所可能加剧既有风险或引发新风险的区域，需遵守相关禁令或管控要求（参见《环境法典》第L562-1条）。此类区域仅适用于自然污染风险防范区域 (RPPs)。
