Map Viewing Service (WMS) of the dataset: 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.

风险源头指一类现实世界实体，其存在本身即构成潜在风险。该风险源头可通过名称进行表征，部分场景下还可借助地理对象定位引发风险的真实实体。实体的位置与危险现象的相关认知，可用于定义风险池（risk pools）——即支撑RPP的风险暴露区域。在PPRTs中，风险源头指代RPP所分析与处置的风险源头处的、符合环保分级标准（CEPI，Classified for Environmental Protection）的设施的围合区域。在PPRT方法学框架下，风险源头被界定为灰色区域。
