Map Viewing Service (WMS) of the dataset: Origin of risk PPRT SAINT-PRIEST

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 hazardous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.In RTPs, it represents the enclosure of the facility(s) classified for environmental protection (ICPE) at the origin of the risk analysed and addressed by the RPP. In the PPRT methodology, it is described as a grey area.风险源表征着一类现实实体，该实体一旦存在便会构成潜在风险。该风险源可通过名称进行表征，在部分场景下还可借助用于定位该风险实际触发实体的地理标识来描述。实体的位置与危险现象的相关认知，被用于划定风险池——即支撑RPP的风险暴露区域。在RTPs中，它指代由RPP分析并处置的风险源处的受环境保护分类（ICPE）设施的围合范围。在PPRT方法体系中，该风险源被描述为灰色地带。
