Arc Flash Compliance

What codes and regulatory requirements exist for arc flash? 

  • NFPA 70E provides guidance on safety requirements for workers engaging in the installation, inspection, operation, maintenance, and demolition of electric conductors and other equipment. It requires an arc flash analysis to determine the proper boundary and safe work processes. It also requires that each panel be marked with an Arc Flash Hazard Warning Label.


  • NFPA 70 has been adopted in all 50 U.S. states as the benchmark for safe electrical design, installation, and inspection. It addresses PPE, labeling, and electrical handling procedures.


  • The Institute of Electrical and Electronics Engineers (IEEE) 1584 provides formulas and methods for determining arc flash boundaries and incident energy.


  • OSHA 29 CFR Part 1910 requires that an employer conduct an assessment to determine if hazards are present which necessitate personal protective equipment (PPE). It also requires that employees wear appropriate PPE for protection and use insulated tools or handling equipment.
