Method and Process for Labeling and Determining Arc Flash Rating on Equipment Through QR Coding

Since the inception of the National Fire Protection Association (NFPA) NFPA 70E, titled Standard for Electrical Safety in the Workplace , which is a standard of the

NFPA, there are labeling requirements to inform employees of potential electrical arc flash hazards and the personal protective equipment required while working on energized electrical equipment. The purpose of NFPA 70E is to provide requirements to reduce worker exposure to electrical hazards. It is concerned with electrical safety in the workplace while the National Electrical Code is concerned

with a safe electrical "installation". NFPA 70E addresses electrical safety concerns in all of the places that the National Electrical Code addresses safe installation practices.

To comply with this code, an arc flash hazard calculation is required to determine the available incident energy and arc-flash hazard boundary distance. NFPA 70A and

IEEE 1584 provide guidelines to perform these calculations given the available fault current, duration of faults, and other general equipment information. Software programs are available to calculate the incident energy and arc-flash hazard boundary distance. It is very important to select the appropriate personal protective equipment (PPE), given a certain task to be performed on electrical equipment. Once the incident energy is calculated, the appropriate PPE that offers protection can be selected. In order for workers to know the incident energy and appropriate PPE for use when working on a specific piece of electrical equipment, the equipment, per NFPA 70E, requires a label to be installed containing the relevant information.

It is very difficult to manage an equipment la...
