2015 NFPA 70E Current Edition


Lives depend on you! Protect your personnel from electrical hazards and meet the highest standard for electrical safety with the 2012 edition of NFPA 70E®.

Workplace safety in the United States is evolving due to better awareness and implementation of NFPA 70E: Standard for Electrical Safety in the Workplace®. Yet hundreds of deaths and thousands of disabling injuries still occur each year due to shock, electrocution, arc flash, and arc blast -- and most could be prevented through NFPA 70E compliance. The 2012 NFPA 70E responds to the challenges, making it easier to ensure an electrically safe working area and comply with OSHA 1910 Subpart S and OSHA 1926 Subpart K.

Help keep your workplace electrically safe with the included 2012 NFPA 70E Permits online tool.

This copy of the 2012 NFPA 70E includes access to 2012 NFPA 70E Permits. Make NFPA 70E compliance easier with:

  • Interactive lookup tables
  • An energized electrical work permit generator
  • Quick and easy look up of your saved permits

Get updated ways to calculate risks and mitigate hazards.

Originally developed at OSHA's request, NFPA 70E responds to information about the effects of arc flash, arc blast, and direct current (dc) hazards, and recent developments in electrical design and Personal Protective Equipment (PPE).

Coverage of direct current hazards is the first of its kind in the U.S.

The rising demand for alternative energy systems such as photovoltaic and wind power present greater dc shock and arc flash hazard exposures to workers. To protect personnel, NFPA 70E includes a new shock protection boundary, hazard/risk table, and incident energy calculation for direct current systems. Revised Article 320 focuses on safe work practices for stationary batteries and battery rooms, such as those used by alternative energy systems.

Make hazard/risk assessments and select proper PPE.

  • Revised requirements delineate the essential difference between "risk assessment" and "hazard identification." Supporting information is in revised Annex F.
  • Hazard/risk tables are expanded to include electrical system characteristics and arc-flash protection boundaries.
  • The 2* designation has been eliminated to clarify that all H/R Category 2 tasks require full-head PPE.
  • Change on "layering" for a combined arc-rating permits the use of arc-rated garments only.<l/i>
  • Clarified text for arc flash hazard warning labels

Give your employees the know-how they need to be electrically safe on the job!

Training and audit-related revisions impact your company's electrical safety program. The 2012 NFPA 70E explains when the energized work permit (EWP) is required and what it should contain; requires emergency procedure instruction on AEDs (Automatic External Defibrillators), adds a new three-year maximum interval for employee training and documentation of content, and more. This edition also contains information about implementing NFPA 70E within the framework of ANSI/AIHA Z10 and other health and safety management standards.
