LIGHTNING PROTECTION AT PETROCHEMICAL FACILITIES - PART 2 REQUIREMENTS OF STANDARDS

Development of lightning protection standards for petrochemical processing and storage facilities has progressed significantly over the past 20 years. Standard requirements have become more stringent and prescriptive. Understanding of development and propagation of lightning has grown with the advent of 3-D detection systems. This is Part 2 of a 3-part primer on lightning protection systems for petrochemical production, storage, and processing facilities. Part 1 - basic science and history. Part 2 - current requirements of national and international standards for protection systems at petrochemical facilities. Part 3 - alternative protection systems. The purpose of this paper, and the primer series, is to update the design and operating engineer's knowledge of lightning protection at petrochemical facilities, and to increase the safety of these facilities to workers and equipment.
