What is Arc Flash?

Arc Flash SuitArc Flash is a brilliant flash, intense heat and pressure wave created when insulating material breaks down or a short circuit occurs. Arc Flash may produce significant amounts of plasma, molten metal, shrapnel and possibly 35,000 degrees F of heat. On average, one experienced, trained electrical worker is killed by electricity each day. It is believed Arc Flash injures nearly 2,500 workers each year.
