NFPA 70E 2027: Key Changes Employers Should Know

What Is NFPA 70E?

The National Fire Protection Association develops codes and standards addressing fire, electrical, and related hazards. NFPA 70E, Standard for Electrical Safety in the Workplace, establishes safety-related work practices intended to reduce employee exposure to electric shock, electrocution, arc flash, arc blast, and other electrical hazards. The current edition is NFPA 70E 2027.

NFPA 70E is not an OSHA regulation, and publication of the 2027 edition does not itself change OSHA requirements. OSHA enforces its own electrical safety standards. Employers commonly use NFPA 70E to help develop work practices that support compliance with 29 CFR 1910 Subpart S and 29 CFR 1926 Subpart K.

OSHA has stated that it does not directly enforce NFPA 70E, although it may use the standard to support citations involving certain OSHA requirements. OSHA has also explained that requirements from a newer edition of NFPA 70E do not become OSHA standards unless OSHA adopts them through rulemaking.

Review the Electrical Safety Program 

NFPA 70E requires employers using the standard to implement and document an electrical safety program based on the risks associated with electrical hazards. That program should translate NFPA 70E requirements into procedures for the employer’s actual equipment, tasks, employees, and working conditions. Simply directing workers to “follow NFPA 70E” does not provide the equipment-specific procedures needed to perform work safely.

The 2027 changes may require updates to employee qualification records, lockout/tagout procedures, audit schedules, energized electrical work permits, testing procedures, PPE selection, and job safety plans.

Change 1: Qualification Is Task- and Equipment-Specific 

Section 110.4 clarifies that a worker’s qualification applies to particular equipment and tasks. A person may be qualified to perform one type of electrical task or work on one category of equipment but remain unqualified for other work.

A job title, license, or general designation as a “qualified electrical worker” should not be treated as blanket authorization for every electrical assignment. Employers should evaluate whether each employee has the training, knowledge, and demonstrated skills needed for the specific equipment and work method involved.

Employers should consider documenting qualification by task and equipment type. A qualification matrix can help supervisors verify that the employee assigned to a job has received the appropriate training and demonstrated proficiency for that work.

Change 2: Lockout/Tagout Requirements and Audits Are More Clearly Separated

Employers should confirm that written procedures distinguish between operating controls and energy-isolating devices. Turning equipment off with a push button or selector switch does not, by itself, establish electrical isolation.

Separate the Four Audit Schedules

The 2027 edition also distinguishes the audit of the overall lockout/tagout program from the audit of individual lockout/tagout procedures. Employers should maintain four audit schedules:

• Electrical Safety Program Audit: At intervals not exceeding three years
• Work Practices Audit: At intervals not exceeding one year
• Lockout/Tagout Program Audit: At intervals not exceeding three years
• Lockout/Tagout Procedure Audit: By a qualified person at intervals not exceeding one year

The annual procedure audit must include at least one lockout/tagout in progress and identify and correct deficiencies involving the procedure, training, and worker execution.

Where OSHA’s general-industry lockout/tagout standard applies, employers must also satisfy OSHA’s separate periodic-inspection requirements. OSHA requires an inspection of each applicable energy-control procedure at least annually, correction of identified deficiencies, employee reviews, and certification of the inspection. The inspector must be an authorized employee other than the employee or employees using the procedure being inspected.

Change 3: Additional Testing May Be Required Beyond Absence of Voltage 

Establishing an electrically safe work condition involves more than opening a switch or disconnect. Employers must identify electrical supply sources, interrupt the load, isolate the equipment, control stored energy, apply lockout/tagout, and verify that the equipment is deenergized.

The 2027 edition expressly addresses situations in which an absence-of-voltage test alone does not confirm that electrical conductors and equipment are deenergized. In those situations, additional testing methods are required. An informational note identifies testing for the absence of current in current-driven circuits as one example.

The employer’s procedure must address the test instrument, required PPE, person performing the test, testing boundary, retesting when conditions change or the location has been left unattended, and verification methods when no accessible exposed point is available for a voltage measurement.

Employers should identify circuits and equipment for which voltage testing may not provide complete verification. The correct additional test method will depend on the equipment, circuit design, energy source, and associated hazards.

Change 4: An Additional Person Is Required for Certain Energized Work

New Section 130.2(A)(2) requires an additional person for certain justified energized electrical work. The requirement applies when both of the following conditions are present:

• An energized electrical work permit is required.
• The permit specifies shock PPE, arc flash PPE, or both.

When both conditions apply, at least one additional person meeting the contact-release training requirements of Section 110.4(C)(1) must be present. That person must remain outside the limited approach boundary or arc flash boundary, whichever extends farther from the hazard.

The additional person must be trained in methods of safely releasing a person from contact with energized electrical conductors or circuit parts. Refresher training in contact-release methods is required annually.

This does not establish a universal two-person rule for every electrical task. The requirement is tied to work for which an energized electrical work permit is required and the permit identifies a need for shock or arc flash PPE.

Employers should revise energized electrical work permits and job safety plans to document:

• Whether an additional person is required
• Who will serve in that role
• Whether the person’s contact-release training is current
• Where the person will be positioned during the work

Change 5: Thermal Hand Protection Is Explicitly Required

New Section 130.7(C)(7)(e) expressly requires thermal hand protection where there is possible exposure to a contact thermal hazard.

Employers should not evaluate gloves only for shock and arc flash protection. Hand-protection selection should account for every applicable hazard associated with the task, including contact with hot equipment, components, tools, or surfaces.

The appropriate protection will depend on the task and exposure. Employers should verify that selected gloves provide the necessary protection without interfering with other required electrical PPE or safe task performance.

Change 6: The Arc Flash Likelihood Table Adds a Battery-Equipment Task

Table 130.5(C)(3), which may be used to estimate the likelihood of an arc flash event, now addresses work on battery equipment below 600 volts where the separation between exposed electrical conductors exceeds 1 mm—or 0.039 inch—per volt.

Under the conditions stated in the table, the estimated likelihood of an arc flash incident for this task is listed as “No.”

That designation does not mean the equipment presents no electrical hazard or that an arc flash risk assessment is unnecessary. The table addresses the likelihood of an arc flash incident, not the potential severity of an injury. NFPA 70E requires likelihood and severity to be considered together when determining whether additional protective measures are necessary.

Employers should avoid interpreting the new entry as a blanket exemption from PPE, shock protection, safe work practices, or other battery-safety controls.

Change 7: Chapter 3 Is Reorganized for DC and Emerging Technologies

The reorganization also includes:

• Article 370: Safety-related work practices for electrical double layer capacitors
• Article 380: Safety-related work practices for photovoltaic systems
• Article 390: Safety-related requirements for research and development laboratories

The new photovoltaic article addresses hazards associated with work on DC photovoltaic arrays, including employee training, qualified-person requirements, risk assessments, and work procedures. The R&D laboratory requirements were moved to Article 390 because they apply across multiple equipment and hazard categories.

Facilities with batteries, capacitors, photovoltaic systems, research laboratories, or other specialized DC equipment should determine which reorganized Chapter 3 articles apply to their operations.

Arc Flash Risk Controls and Hazard Communication

When an arc flash hazard may exist, the risk assessment must evaluate both the likelihood and potential severity of injury. When the selected protective measures include PPE, the employer must determine the applicable safety-related work practices, arc flash boundary, and PPE to be used within that boundary.

PPE is the final level in the hierarchy of risk control. It does not replace hazard elimination, establishment of an electrically safe work condition, engineering controls, safe work procedures, employee training, or lockout/tagout.

Arc flash equipment labels and supplemental electrical safety signs help communicate documented hazard information, boundaries, PPE requirements, and equipment identification. Labels and signs do not perform the risk assessment or determine the correct incident energy, PPE, or work practices.

What Employers Should Do Now

To prepare for NFPA 70E 2027:

• Review Worker Qualifications: Verify that qualification records identify the equipment and tasks each employee is qualified to perform.
• Update Lockout/Tagout Procedures: Confirm that procedures distinguish control devices from energy-isolating devices and properly address simple and complex lockout/tagout.
• Separate Audit Schedules: Track the electrical safety program, work practices, lockout/tagout program, and lockout/tagout procedure audits independently.
• Evaluate Testing Methods: Identify equipment for which absence-of-voltage testing may not fully confirm a deenergized condition.
• Revise Energized Work Permits: Add a process for identifying and assigning the required additional person.
• Review PPE Selection: Account for contact thermal hazards when selecting hand protection.
• Evaluate Battery and DC Work: Review the battery-table revision and determine which reorganized Chapter 3 requirements apply.
• Update Hazard Communication: Confirm that electrical labels and signs reflect current, documented facility assessments and procedures.

Use the published 2027 edition to determine the requirements of NFPA 70E. Applicable federal or state occupational safety requirements and the employer’s documented equipment and task assessments determine the organization’s legal and site-specific obligations.
