We are all responsible for safety. Engineers, contractors, and facility operators must do their part to minimize the risk electricity poses to personnel. Good installation, training, and maintenance practices are indispensable, but engineers also can do a great deal to design for safety. Arc flash is one of the major personnel hazards associated with electrical equipment. NFPA 70E: Standard for Electrical Safety in the Workplace defines the arc flash hazard as, "A dangerous condition associated with the possible release of energy caused by an electric arc." This article aims to highlight some of the little-known design peculiars that can plague the specification/application engineer during a design project.
