If you are responsible for facility electrical operations, you may have heard of the recent updates to IEEE 1584 “IEEE Guide for Performing Arc-Flash Hazard Calculations.” The previous major edition of the standard was in 2002, and many changes have been made in the 2018 version.
An electrical hazard analysis identifies dangers that are present in an electrical system. This starts at the building’s electrical service and continues through the electrical distribution system to the building loads, including panelboards, motors, safety switches, etc. This analysis should identify electrocution (shock) hazards, arc flash (burn) hazards and arc blast (pressure & shrapnel) hazards. more
