This paper highlights an assortment of case studies and explains how arc flash hazards were identified, measured and mitigated at various industry facilities. Case studies will include: Compliance with IEEE 1584-2002 Guide for Performing Arc Flash Hazard Calculations along with regional workplace safety standards for a multi-site global cement manufacturer; Implementation of an Arcflash Reduction Maintenance System™ in an airlock section of a main switch room for a minerals processing plant upgrade; Investigation of an arc flash incident at a chemical processing facility; and a “Safety by Design” upgrade for the iron ore division of a global mining business. The paper will examine the plans and processes reviewed and considered, the strategy deployed to manage/reduce arc flash hazards, and then discuss lessons learned in the implementation of new systems to improve electrical workplace safety.
