INTRODUCTION
Arc flash hazards should be looked upon seriously and with adequate safety measures, training and knowledge. Technology is also instrumental in preventing arc flash hazards. Electrical accident preventions are always in placed but accidents still take a toll on the persons working on the premises. Electricity is a familiar and necessary part of everyday life, but electricity can kill or severely injure people and cause damage to property.
