![]() ![]() This edition emphasized the need to use the hierarchy of risk controls (moved from an informational note into mandatory text) and explicitly stated that the priority must be the elimination of the hazard. The 2018 edition continued to evolve to address risk assessment and introduced human factors, such as human error, as part of the shock and arc flash risk assessments. The hierarchy of risk control methods was introduced in an explanatory/informational note. Risk management terminology was defined and all requirements in the standard were harmonized with risk management principles. Beginning with the 2015 edition, the focus began to shift from PPE requirements to the employer’s duty to create a comprehensive electrical safety program and integrate it into their occupational health and safety management system (OHSMS). In the 1990s and through 2012 the emphasis was on arc flash PPE requirements. In 1995 “limits of approach” and “arc flash” concepts were introduced. In 1981 safety-related work practice requirements were added. The first edition of NFPA 70E was published in 1979 and contained installation safety requirements borrowed from the National Electric Code. Federal OSHA has not incorporated NFPA 70E into the Code of Federal Regulations. It is important to note that NFPA 70E is a voluntary national consensus safety standard published by NFPA primarily to assist OSHA in preparing its electrical safety standards. (See NFPA 70E-2021 Article 130 and OSHA subpart S part 1910.333(a)(1)-(2) and (c) for complete details.) NFPA 70E defines those special circumstances and sets rigid electrical safety limits on voltage exposures, work zone boundary requirements and necessary personal protective equipment (PPE). “Working live” can only be done under special circumstances. For example, OSHA mandates that all services to electrical equipment be done in a de-energized state. NFPA 70E is the tool employers use to meet this OSHA requirement. OSHA bases its electrical safety standards (found in 29 Code of Federal Regulations (CFR) Part 1910 Subpart S and 29 CFR Part 1926 Subpart K) on the comprehensive information found in NFPA 70E.333(a) states that employers must employ safety-related work practices to prevent electrical shock or other injuries resulting from either direct or indirect electrical contact. In the case of NFPA 70E: Standard for Electrical Safety in the Workplace, the OSHA regulations and NFPA standards work so well together it’s been said that OSHA provides the “shall” while NFPA provides the “how.” The Occupational Safety and Health Administration (OSHA) and the NFPA have written many standards and regulations that build on one another. ![]() The National Fire Protection Association (NFPA) is a nonprofit organization devoted to eliminating death, injury, property and economic loss due to fire, electrical and related hazards.
