Map Viewing Service (WMS) of the dataset: Origin of the risk of the PPRT Chemistry Valley

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。该风险源可通过名称加以表征，部分场景下还可借助地理对象对引发风险的实际实体进行定位。依托该实体的位置信息与危险现象的相关认知，可划定风险池（risk pools）——即支撑风险防护预案（RPP）的风险暴露区域。在风险技术流程（RTPs）中，风险源指代由风险防护预案（RPP）所分析、处置的风险源头处的环境保护分类设施（ICPE）的围合范围。在PPRT方法体系中，该概念被描述为模糊区域。
