Abstract

There are some unique electrical safety challenges found in the oil & gas pipeline industry, hereafter referred to as the pipeline industry, that are not normally encountered in the plant environment. One of the more prominent challenges is that pipeline facilities and sites are often unstaffed, in remote areas, and may be in extreme weather locations. Furthermore, pipelines are often located in shared right-of-ways with high voltage electrical utilities, and are cathodically protected which can cause unexpected electrical safety hazards on pipelines, equipment, and appurtenances. If a candid assessment was performed, a large percentage of pipeline maintenance and operations employees would likely be found to have only minimal electrical safety training and knowledge, yet routinely perform specific nonexposed energized electrical tasks such as lockout / tagout of equipment and starting an electric motor. This paper will introduce the concept of an Authorized Person as a means of recognizing this group of persons who routinely perform nonexposed energized electrical tasks as part of normal job duties to ensure they receive the appropriate levels training, knowledge, and tools as part of an electrical safety program. Often this group of persons can be an underappreciated aspect of an electrical safety program. Authorized Persons are a subset of Qualified Persons as defined by NFPA 70E, and are qualified for the task per NFPA 70E, but are only authorized to perform specific non-exposed energized electrical work. For the pipeline industry, this provides a convenient designation to distinguish between persons who have the training, knowledge, and skills to perform exposed energized electrical work from those that only perform non-exposed energized electrical work as part of normal job duties. New considerations for advancing electrical safety programs have been outlined in this paper due to the introduction of the Authorized Person concept.
引进授权人员推进电气安全项目
在石油和天然气管道行业(以下简称管道行业)中,存在一些在工厂环境中通常不会遇到的独特的电气安全挑战。其中一个更突出的挑战是,管道设施和站点通常无人值勤,位于偏远地区,可能处于极端天气地区。此外,管道通常位于与高压电力公用设施共用的通行权处,并且受到阴极保护,这可能会对管道、设备和附件造成意外的电气安全危害。如果进行坦率的评估,大部分管道维护和操作员工可能只接受过最低限度的电气安全培训和知识,但却经常执行特定的非暴露的带电电气任务,如设备的锁定/标签和启动电动机。本文将介绍授权人员的概念,作为一种手段来识别这组人员,他们经常执行非暴露的带电电气任务,作为正常工作职责的一部分,以确保他们接受适当水平的培训,知识和工具,作为电气安全计划的一部分。通常,这群人可能是电气安全程序中不被重视的方面。授权人员是NFPA 70E定义的合格人员的一个子集,并且根据NFPA 70E有资格完成任务,但仅被授权执行特定的非暴露通电电气工作。对于管道行业,这提供了一个方便的名称,以区分受过培训、有知识和有技能从事暴露带电电气工作的人员和那些只从事非暴露带电电气工作的人员,这些工作是正常工作职责的一部分。由于授权人概念的引入,本文概述了推进电气安全计划的新考虑。
