Surface entity at the origin of the PPRT SI GROUP in Bethune in Pas-de-Calais

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP. In PPRTs, it represents the enclosure of the facility(s) classified for environmental protection (CEPI) at the origin of the risk analysed and addressed by the RPP. In the PPRT methodology, it is described as a grey area.

风险源是指现实世界中，其存在本身即构成潜在风险的实体。该风险源可通过名称予以标识，部分场景下还可通过定位引发风险的实际实体的地理对象来补充其位置信息。该实体的位置与危险现象的相关认知，可用于界定风险池（Risk Pool）——即支撑RPP的风险暴露区域。在PPRT场景中，该风险源指代RPP所分析与处置的风险源处，已按环境保护分类（CEPI）划定的设施保护范围。在PPRT方法学框架内，该风险源被描述为灰色区域。
