摘要

联邦法规(CFR)是联邦机构的一般和永久规则的法规集合。本案例研究具体涉及地下管线和阀门站的腐蚀控制和电气保护两个部分。危险液体的运输由美国联邦法规第49条第195条规定,天然气的运输由美国联邦法规第49条第192条规定。满足要求的一种方法是安装设备和系统,将阴极保护的管道和阀站与附近接地的结构和设备隔离开来。本案例研究的重点是工业装置,在安装所需的隔离装置后,工人无意中暴露在高于预期的电压下。

Case Study: Unforeseen Shock Hazards from Code Compliance at an Above Ground Pipeline Valve Station
The Code of Federal Regulations (CFR) is a regulatory collection of general and permanent rules of federal agencies. This case study is specific to two sections pertaining to the control of corrosion and electrical protection of underground pipe lines and valve stations. The transportation of hazardous liquids is covered by 49 CFR 195, and the transportation of natural gasses is covered by 49 CFR 192. A method of meeting compliance is with the installation of devices and systems to electrically isolate a cathodically protected pipe line and valve stations from nearby grounded structures and equipment. This case study focuses on an industrial installation where a worker was inadvertently exposed to higher than expected voltages after the installation of the required isolation devices.
