Right in front of you on the switchboard, a bright orange label reads: "WARNING Arc Flash Hazard, Appropriate PPE Required." As you look closer at the label, you also see: "6.5 cal/cm~2 at a working distance of 18 inches."rnThis is all part of your company's recently updated electrical safety practices. Based on the calculated incident energy in calories per centimeter squared (cal/cm~2) at the equipment location, you are now required to wear flame-retardant clothing and related personal protective equipment (PPE) anytime an arc flash hazard exists.
