OSHA to NFPA 70E Crosswalk

“Is 70E the law?” No — and that answer is incomplete in a way that gets employers cited. Here is exactly where each OSHA requirement meets the 70E article that satisfies it.

01Why this crosswalk exists

The question I get in every class, usually within the first hour: “Is NFPA 70E the law?”

No. NFPA 70E is a consensus standard. OSHA regulations are the law. But that answer, left alone, is dangerously incomplete — because OSHA's electrical regulations are brief where 70E is detailed, and OSHA uses 70E to establish that an electrical hazard was recognized and that a feasible means of abatement existed. That is how arc flash gets cited under the General Duty Clause.

So the practical relationship is this: OSHA tells you what you must accomplish. NFPA 70E tells you how, and becomes the yardstick you are measured against. This crosswalk maps the connection point by point.

02The crosswalk

OSHA – NFPA 70E crosswalk 22 of 22 shown

1910.132(d)Art. 130.5PPE

Hazard assessment for PPE

OSHA requires the employer to assess the workplace to determine whether hazards are present that necessitate PPE, and to certify in writing that the assessment was performed. NFPA 70E supplies the method for the electrical portion: the arc flash risk assessment and the shock risk assessment.

In practice: The written certification is the part that gets missed. Many facilities perform a real assessment and never document it — which, to an inspector, is indistinguishable from never having done it.

1910.132(h)Art. 130.7PPE

Employer payment for PPE

OSHA requires the employer to pay for required PPE, with narrow exceptions. Arc-rated clothing and rubber insulating gloves required by the electrical safety program fall inside the requirement.

In practice: This surfaces most often as daily-wear arc-rated clothing programs. If the clothing is required to comply, cost-sharing arrangements deserve a careful look.

1910.137Art. 130.7(C)PPE

Electrical protective equipment — rubber insulating goods

OSHA sets the design requirements and the in-service care and use requirements for rubber insulating gloves, sleeves, blankets, covers, line hose, and matting — including the periodic electrical retest intervals. NFPA 70E incorporates the same expectation into the PPE program.

In practice: The retest stamp is the single easiest deficiency for an inspector to document: open the glove bag, read the date. If you audit one thing this quarter, audit this.

1910.147Art. 120Lockout / ESWC

The control of hazardous energy (lockout/tagout)

OSHA's LOTO standard covers hazardous energy generally. NFPA 70E Article 120 supplies what a generic LOTO program almost never does for electrical energy: the process for establishing an electrically safe work condition, including verifying absence of voltage with an adequately rated instrument and addressing stored electrical energy.

In practice: 1910.147 explicitly does not cover work on energized parts for which the employer demonstrates the work must be performed energized. That is where 70E Article 130 and the energized work permit take over — the two standards interlock rather than overlap.

1910.147(c)(4)Art. 120.5Lockout / ESWC

Equipment-specific energy control procedures

OSHA requires documented procedures for the control of hazardous energy that identify the specific energy sources and the specific steps for the specific machine. Generic plant-wide procedures satisfy this only under a narrowly drawn exception.

In practice: This is the requirement behind the most common serious finding I see: one generic electrical LOTO procedure used for hundreds of pieces of equipment, none of which names its own second source.

1910.269Art. 130 / AnnexUtility

Electric power generation, transmission, and distribution

A separate OSHA standard applying to work on utility-scale generation, transmission, and distribution installations — including its own arc flash hazard analysis and clothing requirements. Which standard governs turns on the installation, not on who employs the worker.

In practice: The scope boundary between 1910.269 and Subpart S is a recurring source of confusion at industrial plants with their own substations and at solar and wind sites. Getting it wrong means applying the wrong PPE regime entirely. NEEDS SME REVIEW confirm the current scope language and the 2027 edition's treatment.

1910.301–.308NFPA 70 (NEC)Installation

Subpart S — design safety standards for electrical systems

The installation half of OSHA's electrical rules. These sections are drawn from the National Electrical Code and govern how the system is built — wiring design, protection, grounding, and equipment for special conditions.

In practice: Installation defects found during a 70E-driven walkdown are citable under these sections even though you found them doing safety work. Have a plan for what you do with what you find.

1910.331Art. 110 / 120 / 130Work practices

Scope of the safety-related work practices

Establishes who the work-practice rules cover: qualified persons working on or near exposed energized parts, and unqualified persons whose work brings them near enough to be exposed. NFPA 70E is the consensus standard that details how to comply.

In practice: The unqualified-person half of this scope is the one programs forget. Painters, riggers, HVAC techs, and cleaning crews are covered when their work puts them near exposed energized parts.

1910.332Art. 110.4Training

Training

OSHA requires training for employees who face a risk of electric shock, with the content and degree determined by the risk. NFPA 70E specifies the training in far more detail: qualification for specific tasks and equipment, retraining intervals and triggers, documented emergency response, and awareness training for unqualified persons.

In practice: OSHA's text is short and the details are in 70E — which is exactly why inspectors reference 70E when evaluating whether the training was adequate. “We met 1910.332” is not a defense if the training did not produce a qualified person.

1910.333(a)Art. 110.3 / 130.2Work practices

De-energizing is the default; energized work is the exception

OSHA requires that live parts be de-energized before an employee works on or near them, unless the employer can demonstrate that de-energizing introduces additional or increased hazards, or is infeasible due to equipment design or operational limitations. NFPA 70E Article 130 builds the energized electrical work permit around that same test.

In practice: Note what is not in the exception: schedule, cost, customer preference, and inconvenience. This sentence is the legal backbone of every energized work permit, and it is worth quoting verbatim in your program.

1910.333(b)Art. 120Lockout / ESWC

Lockout/tagout for electrical work practices

The work-practice side of locking out: procedures, application of locks and tags, verification of de-energization, and re-energizing. Article 120 of 70E aligns and adds the test-before-touch discipline.

In practice: Verification is where the paperwork and the reality most often diverge. A signature on a LOTO form is not a voltage reading.

1910.333(c)Art. 130.4Work practices

Working on or near exposed energized parts — approach distances

OSHA sets minimum approach distances for unqualified persons and requires qualified persons to be capable of working safely on energized circuits, with appropriate techniques and insulating equipment. NFPA 70E Table 130.4 gives the limited and restricted approach boundary values that make this operational.

In practice: OSHA gives you the duty; 70E gives you the numbers. That relationship — enforceable regulation plus consensus standard supplying the method — is the whole reason 70E matters to a compliance conversation.

1910.334Art. 110 / 130.7Work practices

Use of equipment — cords, tools, and test instruments

Covers portable electric equipment, extension cords, and critically, test instruments and equipment: they must be rated for the circuits they will be connected to and must be visually inspected before use.

In practice: Test instrument rating (CAT rating) is a routinely overlooked control. A meter rated for the wrong category on a high-energy circuit is a documented arc flash initiator, not a diagnostic tool.

1910.335(a)Art. 130.7PPE

Personal protective equipment for electrical work

Requires PPE for parts of the body exposed to electrical hazards, that it be maintained in a safe condition and inspected, and that non-conductive head protection and eye/face protection be used where the hazard warrants it.

In practice: “Maintained and periodically inspected” means you need a documented inspection and removal-from-service process. Without a removal process, damaged gear cycles back into the locker.

1910.335(b)Art. 130.8Work practices

Alerting techniques — barricades, signs, and attendants

Requires safety signs and tags, barricades, and where those are insufficient, an attendant to warn and protect employees.

In practice: The attendant requirement is the ancestor of the additional-person discussions in the 70E cycle. If a barricade cannot keep people out, a person has to.

1926 Subpart K (1926.400–.449)Art. 110 / 120 / 130Construction

Construction industry electrical standards

Construction work is governed by Part 1926, not Part 1910. Subpart K carries its own installation safety requirements, safety-related work practices, and requirements for special equipment.

In practice: If your electricians perform construction activity — new installation, alteration, major repair — the construction standard applies to that work even inside a general industry facility. Programs written only to 1910 leave this exposed.

1926.416(a)Art. 110.3 / 130Construction

Construction — protection of employees from energized circuits

Prohibits permitting an employee to work in proximity to any part of an electric power circuit that the employee could contact, unless the employee is protected by de-energizing and grounding or by effective insulation.

In practice: The construction-side analogue to 1910.333(a). Contractors on your site are working to this section while your own crews may be working to 1910 — a distinction worth naming in the host/contractor information exchange.

1926.21(b)(2)Art. 110.4Training

Construction — employee training in hazard recognition

Requires the employer to instruct each employee in the recognition and avoidance of unsafe conditions and the regulations applicable to the work environment.

In practice: This general training duty is frequently cited alongside electrical violations, because it lets OSHA reach the question of whether the employee should have recognized the hazard at all.

1910.303(g)(1)Art. 110 / 130Installation

Working space about electrical equipment

Requires sufficient access and working space about electrical equipment likely to require examination, adjustment, servicing, or maintenance while energized — with specified depth, width, and headroom.

In practice: Blocked working space is one of the most commonly cited electrical conditions and one of the cheapest to fix. It is also a genuine safety control: escape distance matters in an arc flash event.

1910.303(e) & (f)Art. 130.5(H)Installation

Marking and identification of disconnecting means

Requires equipment marking with manufacturer and ratings, and that each disconnecting means be legibly marked to indicate its purpose unless the purpose is evident.

In practice: Mislabeled and unlabeled disconnects appear in a striking share of electrocution investigations. This is a low-cost, high-return item — and it is separately citable from your arc flash labeling.

1904.39—Reporting

Reporting fatalities and severe injuries to OSHA

Requires reporting a work-related fatality within 8 hours, and any work-related inpatient hospitalization, amputation, or loss of an eye within 24 hours. Electrical burns and electrocutions routinely trigger both.

In practice: Know the number and the clock before you need them. Several State Plan states impose shorter or additional reporting requirements — California's 8-hour serious injury reporting under 8 CCR §342 is the example I cite most.

Section 5(a)(1)All of NFPA 70EGeneral Duty

The General Duty Clause

Where no specific standard applies, OSHA may cite the General Duty Clause: the employer must furnish a workplace free from recognized hazards causing or likely to cause death or serious physical harm. Arc flash has historically been cited this way, using NFPA 70E as evidence that the hazard is recognized and that feasible abatement exists.

In practice: This is the single most important thing to understand about 70E's legal weight. OSHA does not incorporate NFPA 70E by reference — but 70E is the document used to establish that the hazard is recognized and that a feasible means of abatement was available to you. Compliance with 70E is how you make that argument go away.

No entries match that search. Try a broader term, or clear the filter.

03Three things this table does not show

State Plan differences. Twenty-two states and territories operate OSHA-approved State Plans covering private employers, and several adopt requirements more stringent than federal OSHA. California's Title 8 electrical safety orders are the clearest example. Check your state page before you rely on a federal citation.
Which edition applies. OSHA regulations are amended rarely; NFPA 70E is revised every three years. When OSHA references the standard as evidence of a recognized hazard, the edition in force at the time of the exposure is what matters.
Other standards in the stack. NFPA 70B for electrical equipment maintenance, NFPA 70 (the NEC) for installation, IEEE 1584 for incident energy calculation, and the ASTM PPE standards all sit inside this picture. A defensible program cites all of them.

Want this mapped to your facility, not to a generic plant?

An electrical safety program build includes the regulatory stack that actually applies to you — federal or State Plan, general industry or construction, 1910.269 or Subpart S — written into the program rather than left for someone to work out during an inspection.
