Beyond the Calculations: Life After Arc Flash Analysis

Abstract

Once an arc flash analysis has been performed for a facility, the quantification of the potential incident energy has been completed. However, this is only the first step in establishing and implementing a complete arc flash program. Labels must be applied to the equipment and the information presented must be appropriately meaningful and instructive to qualified persons preparing to access the energized equipment. Arc Flash warning labels are only one type of arc flash documentation that should be presented and available to facility personnel. A comprehensive safety policy and corresponding training program should be developed and implemented to ensure understanding and compliance with the procedures in place to reduce the impact of a potential arc flash hazard. Lastly, a preventative maintenance program must be put into place to ensure that all electrical equipment, most importantly the protective devices, will react appropriately during an arc flash event.
