Properly Labeling Electrical Equipment Can Prevent Arc Flash Incidents in the Workplace
Robert E. Henry, PE
This simplified method to label electrical equipment includes accurate arc-fault values and is a cost-effective way to reduce arc flash hazards.
Arc flashes in electric equipment are hazardous to workers and can result in fatalities, costly damage to equipment and delays in production until repairs are made. Arc-flash labels on electrical equipment are required by federal law; OSHA regulations requiring these labels have existed since approximately 2000.
Unlabeled equipment is a safety violation, and if facilities managers have not hired people to label their electrical equipment, they risk increased insurance costs.
