Simple download service (Atom) of the dataset: Surfacing entity at the origin of the risk of a PPRT on the Meuse department (55)

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.

风险源是指凭借自身存在构成潜在风险的现实世界实体。该风险源可通过名称进行表征，在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明确其相关信息。实体的位置信息与危险现象相关知识，可用于界定风险池——即支撑RPP运作的风险暴露区域。
在PPRT中，该风险源指代经RPP分析与处置的风险对应的风险源处的环境保护分级设施（CEPI，classified for environmental protection）的围合区域。在PPRT方法体系中，该围合区域被描述为灰色区域。
