NFPA 70E®: Standard for Electrical Safety in the Workplace® reduces the risk of death or injury due to electrical hazards.

Used correctly, the safe work practices in NFPA 70E can stop workplace electrical accidents before they happen by reducing exposure to major electrical hazards. Originally developed at OSHA's request, NFPA 70E helps companies and employees avoid workplace injuries and fatalities due to shock, electrocution, arc flash, and arc blast, and assists in complying with OSHA 1910 Subpart S and OSHA 1926 Subpart K. Each edition of NFPA 70E builds on the next, incorporating the latest research and "lessons learned" from the field.

  • The 2009 NFPA 70E: Electrical Safety in the Workplace introduces an easier way to calculate incident energy -- the first step in determining PPE -- with revised Annex D that consolidates equations, adds tables, and provides alternatives to making detailed calculations. Other changes in this edition recognize a broader array of hazards and help reduce safety gaps. To further reduce the risks for second-degree thermal burns, cotton outerwear is no longer permitted for energy levels below 2 cal/cm2. An expanded Table in Article 130 covers added tasks such as thermographic imaging, and new equipment including arc-resistant switchgear. New Article 350 offers the Standard's first requirements for the protection of electrical personnel in R&D labs. New recordkeeping requirements for training and safety program audits respond to OSHA's need for records.
  • The 2004 NFPA 70E: Electrical Safety in the Workplace improves compatibility with the NFPA 70®: National Electrical Code® (NEC®) with a new format featuring corresponding provisions. Installation criteria correlate with the 2002 NEC. To reduce the potential for errors, Safety Related Work Practices are prioritized to provide more specific safety guidance, and revised PPE requirements help minimize unsafe exposures. A new provision for a signed authorization for energized electrical work further reduces the likelihood of electrical accidents. New language concerning multi-employer relationships requires all contractors on a project to be aware of hazards, PPE, safe work practices, and emergency evacuation procedures. Definitions clarify electrical safety issues such as arc rating, incident energy, and restricted approach boundary.
