NFPA 70E 2027 Updates: What Employers Need to Know About the New Requirements

With the NFPA 70E 2027 updates now in effect, employers should understand how the latest edition of NFPA 70E®, Standard for Electrical Safety in the Workplace® affects electrical safety programs and work practices. Effective May 6, 2026, the revised standard includes updated guidance for energized work, emergency response, electrical risk assessments, personal protective equipment (PPE), battery systems, direct-current (DC) equipment, photovoltaic (PV) systems, and stored electrical energy.

NFPA 70E provides recognized safety practices to help protect employees from electrical hazards, including electric shock, arc flash, electrical burns, and other electrical-related injuries. Although NFPA 70E is not an OSHA regulation, OSHA may reference recognized industry standards when evaluating whether employers have adequately protected employees from known electrical hazards. 

Key Changes in the NFPA 70E 2027 Update 

Additional Support During Certain Energized Electrical Work 

When energized electrical work requires an Energized Electrical Work Permit and the permit specifies the use of electric shock or arc flash PPE (or both), at least one additional person must be present at—but outside of—either the limited approach boundary or the arc flash boundary, whichever is greater. The additional person must be trained in emergency-response procedures appropriate for the hazards involved. Depending on the work, this may include emergency communication, safe release from electrical contact, first aid, CPR, or AED use. 

This requirement does not mean two employees are required for every electrical task. It applies to specific energized work performed under an Energized Electrical Work Permit. 

Expanded Verification of an Electrically Safe Work Condition 

Testing for the absence of voltage remains a critical step when establishing an electrically safe work condition. However, some equipment may store or produce hazardous electrical energy even when voltage is no longer detected. 

NFPA 70E 2027 Updates: Multimeter used to test voltage

The updated standard recognizes that additional testing, such as testing for the absence of current, may be necessary for certain current-driven circuits. Employers should evaluate systems involving batteries, capacitors, stored energy, induced energy, or other conditions where absence-of-voltage testing alone may not confirm that all electrical hazards have been eliminated. 

Greater Attention to Thermal Contact Hazards 

Electrical equipment may become hot enough to cause burns even when an arc-flash event does not occur. Electrical risk assessments should consider potential contact with hot electrical components and determine whether additional protective measures, including thermal hand protection, are necessary. 

Updated Arc-Flash Risk Assessment Information 

The NFPA 70E 2027 update includes clarifications related to arc flash risk assessments, including additional consideration of certain direct current (DC) equipment operating below 600 volts.

The standard also recognizes that some electrical equipment may include manufacturer-provided incident-energy information. This information may support an arc-flash evaluation when it accurately represents the installed equipment and operating conditions. Manufacturer information should not automatically replace a facility-specific evaluation without confirming that it applies to the equipment configuration and work being performed. 

Manufacturer information should not automatically replace a facility-specific evaluation without confirming that it applies to the equipment configuration and work being performed. 

Electrical PPE Requirements 

The updated standard places greater emphasis on recognized testing and conformity-assessment processes for certain electrical PPE, and now requires third-party certification or a supplier’s declaration of conformity (SDOC) backed by a registered quality management system and accredited lab testing (existing compliant PPE is grandfathered).

Employers should continue verifying that electrical PPE: 

  • Is appropriate for the identified electrical hazard 
  • Meets applicable performance standards 
  • Is properly inspected, maintained, and stored 
  • Is replaced when damaged, defective, contaminated, or no longer suitable 

The release of the new edition does not mean that all existing arc-rated clothing or electrical PPE must be replaced. Existing equipment should be evaluated based on its condition, rating, compliance, and suitability for the identified hazards. 

Expanded Requirements for Batteries and Stored Energy 

Battery systems may present hazards beyond electric shock and arc flash. These hazards will depend on the technology and application

Hazards may include: 

  • High short-circuit energy 
  • Thermal hazards 
  • Chemical exposure 
  • Fire or explosion 
  • Flammable or toxic gases 
  • Thermal runaway 

The updated standard provides additional guidance for evaluating battery-related hazards and includes new requirements addressing electrical double-layer capacitors, also known as supercapacitors or ultracapacitors. 

Employers should ensure that procedures address stored electrical energy and confirm that hazardous energy has been safely discharged before work begins. 

New Guidance for DC and Photovoltaic Systems 

Among the changes in the NFPA 70E 2027 update are new requirements addressing direct-current (DC) electrical hazards and photovoltaic (PV) systems.

DC systems are increasingly common in battery installations, energy-storage systems, renewable-energy equipment, electric-vehicle systems, and industrial applications. These systems may require different hazard assessments, testing methods, work practices, and protective measures than traditional alternating-current systems. 

PV systems also present unique concerns because solar panels may continue producing electrical energy when exposed to light. The standard now mandates detailed risk assessments prior to any physical connector manipulation and requires verification of zero load current before attempting to disconnect PV circuits.

Organizations that own, operate, install, inspect, or maintain these systems should review existing procedures to ensure these hazards are properly addressed. 

What Should Employers Do? 

Employers should review their electrical safety programs and determine which changes apply to their operations.

Key actions may include: 

  • Reviewing Energized Electrical Work Permit procedures
  • Updating electrical safety policies and training materials 
  • Evaluating emergency-response requirements for energized work 
  • Reviewing procedures for batteries, DC systems, photovoltaic systems, capacitors, and stored energy 
  • Confirming that electrical PPE remains appropriate and compliant 
  • Evaluating thermal contact hazards 
  • Reviewing electrical procedures for outdated NFPA 70E section references 

The release of the 2027 edition does not automatically require employers to repeat all arc-flash studies, replace electrical labels, purchase new PPE, or retrain every employee immediately. Existing programs, studies, labels, PPE, and training should be reviewed to determine whether updates are necessary. 

Existing programs, studies, labels, PPE, and training should be reviewed to determine whether updates are necessary. 

Navigating the NFPA 70E 2027 Updates 

The 2027 edition of NFPA 70E reflects changes in electrical technology and provides updated practices for protecting employees from electrical hazards. For many organizations, the appropriate first step is a documented review of the existing electrical safety program, work practices, training, risk assessments, PPE, and emergency-response procedures. Organizations using batteries, DC equipment, photovoltaic systems, or other energy-storage technologies may require additional evaluation.

We may have already had a taste of fall weather, but high temperatures returned quickly to remind us that we’re not quite finished with summer just yet. Here are some good tips, tools, and resources to help you better protect your skin from harmful sunlight while enjoying days in the heat. What are UV Rays? UV stands for ultraviolet, which is a type of light that comes from the sun. There are two main types of UV rays that can reach us: UVA and UVB. While sunlight helps us stay warm and can be good for getting vitamin D, too much UV light can be harmful to our skin and eyes. Why is it important to be “Sun Safe”? Excessive exposure to UV rays can cause sunburns, a painful reddening of the skin.  Over time, UV exposure increases your risk for skin cancers like squamous cell and basal cell carcinomas, and cutaneous melanoma.  UV light can also damage your eyes and can lead to cataracts and macular degeneration. How Can You Stay Safe? Wear Sunscreen: Always put on sunscr...

Worker Burned After Tank Explodes — Company learns why machine-specific LOTO procedures are needed

** This is a true story. Names and certain details were changed to preserve anonymity. A busy R&D company was working on a sustainability project involving alternative fueling options for a piece of equipment at their facility. The project was long awaited, had underwent much research and was finally at the testing stage which involved a new fuel source being pumped into a propane tank that was already onsite. The project manager, Steve, and maintenance man, Rob, were in charge of oversight on the fueling of the propane tank. When the Job Began With no machine-specific procedure established, Steve began by locking out the lines of the tank based off of his knowledge and proceeded with loading the new fuel. However, as luck would have it, the truck dispensing the fuel was having issues with the pump stalling, so, after multiple attempts, Steve and the truck’s driver decided to call it quits. The driver disconnected, bled the lines, and left. Before leaving, Steve told Rob how t...

Formaldehyde Found to be Carcinogenic to Humans Via Inhalation

A final toxicological review by EPA’s Integrated Risk Information System (IRIS) program finds that formaldehyde is carcinogenic to humans through the inhalation route of exposure. The report, released in August 2024, concludes that formaldehyde inhalation can cause several upper respiratory tract cancers and myeloid leukemia, and establishes a reference concentration (RfC) for formaldehyde of 7 µg/m3 (~0.006 ppm). EPA defines the RfC as “the level of continuous inhalation exposure to the human population (including sensitive subgroups) that is likely to be without appreciable risk of deleterious effects during a lifetime.” The report, released in August 2024, concludes that formaldehyde inhalation can cause several upper respiratory tract cancers and myeloid leukemia In occupational settings, the Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for formaldehyde is 0.75 parts per million (ppm) over an 8-hour workday. The short-term exposure limit...
