This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a specified date. This is the following: — prescribed scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集收录了PPRN发展各阶段的边界范围。此类边界的核心特征为：其效力源于官方法定程序，并自指定日期起正式生效。具体如下： — 自然类或人工类PPR的审批指令文书中载明的法定适用范围； — 经批准的RPP所规制范围对应的风险暴露范围；该获批边界属于公用役权范畴，其中PPRN对应PM1，PPRT对应PM3； — 对应危险源研究覆盖域的研究范围。
