Arc Flash Analysis is a safety study that electrical engineers perform to evaluate potential electrical hazards in workplaces. Think of it like a safety inspection for electrical systems, but specifically focused on the dangers of powerful electrical explosions (called arc flashes). Companies need this analysis to protect workers, meet safety regulations, and create proper safety guidelines. This is similar to other workplace safety assessments, but specifically deals with electrical dangers. You might also see this referred to as "Arc Flash Study," "Arc Flash Assessment," or "Arc Flash Hazard Analysis."
