Surface-based entity at the origin of the risk of ARC INTERNATIONAL FRANCE’s PPRT

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.风险源即指一类现实世界实体，该实体的存在本身即构成潜在风险。该风险源可通过名称进行表征，部分场景下还可通过定位该风险实际致险实体的地理对象来补充描述。实体的位置与危险现象的认知信息，被用于定义风险池——即支撑RPP的风险暴露区域。在PPRT框架中，该风险源指代RPP所分析与处置的风险源处的按环境保护要求分类（CEPI）设施的围合范围。在PPRT方法体系内，该风险源被描述为灰色区域。
