OSHA is citing and fining employers for failure to protect employees from the dangers of arc flash. For guidelines on how to protect employees, OSHA refers employers to the NFPA 70E standard, “Standard for Electrical Safety in the Workplace.”
This document provides information on the most current arc flash labeling requirements, as well as best practices for creating and maintaining such labels. In the 2015 version of the NFPA 70E standard, arc flash labeling requirements are covered under Article 130.5(D) and 130.7(E)(1). Additional labeling requirements are also included in Article 110.16 of the 2014 version of the National Electric Code (NEC).
