What is an NFPA 70E Qualified Person?
Definition, Requirements & Responsibilities
An NFPA 70E qualified person is someone who has demonstrated skills and knowledge related to the construction and operation of electrical equipment and installations and has received safety training to identify hazards and reduce the associated risk.
In short, qualification is task-specific and equipment-specific: a worker can be qualified for one piece of equipment or job and unqualified for another. Time served does not make someone qualified by itself.
This distinction matters because NFPA 70E, the Standard for Electrical Safety in the Workplace, uses the word “qualified person” more than 150 times, and after an electrical accident it often becomes the central question in any investigation.
Below is what defines a qualified person, what training the standard requires, and which tasks a qualified person may perform that an unqualified worker cannot.
NFPA 70E Definition of a Qualified Person
NFPA 70E Article 100 defines a qualified person as “one who has demonstrated skills and knowledge related to the construction and operation of electrical equipment and installations and has received safety training to identify the hazards and reduce the associated risk.”
Two parts of that definition do the heavy lifting:
- Demonstrated skills and knowledge. It is not enough to have attended training or to hold a license or certificate. The person must be able to show competence on the specific equipment and circuits involved in the work.
- Hazard identification and risk reduction. The person must be trained to recognize electrical hazards such as shock and arc flash, and to apply the practices that reduce the risk of injury that accompanies these hazards.
A common misconception is that an experienced electrician is automatically qualified. NFPA 70E rejects that idea.In fact, nothing says that a person must be an electrician to be considered a qualified person either. A worker may be qualified to perform one electrical task but not another, and qualified on one type of equipment but not on a similar type. Qualification is always scoped to the equipment and the task at hand.
Qualified Person vs. Unqualified Person
Factor | Qualified Person | Unqualified Person |
Definition | Demonstrated skills/knowledge + hazard training for specific equipment | Has not demonstrated skills/knowledge or otherwise has not been deemed a qualified person |
Crossing the limited approach boundary | May enter unescorted with proper PPE | Only when escorted by a qualified person |
Crossing the restricted approach boundary | May enter with documented plan, PPE, and approval | Never permitted under any circumstance |
Energized work | May perform within scope of qualification | Not permitted |
Required training | Comprehensive, equipment-specific | Awareness-level safety practices for their own protection |
An unqualified person is defined in NFPA 70E as being “a person who is not a qualified person.” However, this does not mean untrained, in fact, NFPA 70E requires that unqualified persons still be trained in and familiar with any electrical safety-related practices necessary for their safety.
The classic example is administrative staff who need to know not to cross a barricade or to plug in a frayed cord or run cords under carpet, even though they never work on electrical equipment.
Training Requirements for a Qualified Person
NFPA 70E Section 110.4 sets out what a qualified person must be trained in. A qualified person shall be trained and knowledgeable in the construction and operation of equipment or a specific work method, and trained to identify and avoid the electrical hazards present with that equipment or method.
Qualified-person training must cover:
- Safe work practices and hazard recognition for the specific equipment and task.
- Proper use of PPE, insulating and shielding materials, and insulated tools and test equipment.
- Special precautionary techniques and the applicable electrical policies and procedures.
- Determining nominal voltage of exposed energized parts.
- Distinguishing energized parts from other parts of electrical equipment, plus the approach distances and corresponding voltages, for anyone permitted to work within the limited approach boundary.
- Verifying the absence of voltage, including how to correctly select and use a test instrument to confirm de-energization.
Importantly, NFPA 70E does not mandate a fixed number of training hours. Training length depends on the worker’s role and level of hazard exposure. In practice, comprehensive qualified-person training often runs several hours and benefits from hands-on, equipment-specific instruction rather than a lecture alone.
New for the 2027 edition of NFPA 70E, qualified persons that will use test equipment must demonstrate that they know how to use the test instrument to test for the absence of voltage. The important thing is that the training is appropriate for the job they will need to perform as a qualified person.
Who designates a qualified person?
The employer designates qualified person status, not a training provider. Holding a current NFPA 70E certificate does not by itself make someone qualified.
The employer must verify demonstrated competence, supervise the worker, and confirm that the person complies with the required safety-related work practices.
A worker undergoing on-the-job training can be considered qualified for the task only while under the direct supervision of a qualified person.
How often is retraining required?
Retraining is required at intervals not exceeding three years. NFPA 70E Section 110.4(A)(4) requires retraining in safety-related work practices and any applicable changes to the standard at least every three years, which aligns with the standard’s three-year revision cycle.
Additional retraining is required sooner whenever certain conditions exist, such as when the employee’s job duties change, when new equipment or procedures are introduced, or when a review reveals that the employee is not following safe work practices. The goal is to combat knowledge decay and keep workers current with the equipment they actually use.
What Tasks Can a Qualified Person Perform?
A qualified person may perform tasks involving exposed energized conductors and circuit parts that an unqualified person cannot, provided the task falls within their specific qualification. These include:
- Crossing the limited approach boundary unescorted while wearing appropriate PPE.
- Performing testing, troubleshooting, and voltage verification on the equipment they are qualified for.
- Working within the restricted approach boundary when all necessary permits, a documented plan, appropriate PPE, and supervisor approval are in place.
- Selecting and applying PPE and insulated tools suited to the shock and arc flash hazards present.
By contrast, unqualified persons may never cross the restricted approach boundary, and may only enter the limited approach boundary when a qualified person advises them of the hazards and continuously escorts them.
Why the Qualified Person Designation Matters
The qualified person concept is the backbone of NFPA 70E compliance and a frequent focal point in OSHA enforcement and accident litigation.
After an incident, investigators ask a single decisive question: Was the person qualified for that task? If the employer cannot document demonstrated skills, hazard-specific training, and current retraining, the answer creates serious liability.
Treating qualification as task-specific rather than a blanket title protects workers and the organization. It ensures the right person, with the right training, performs each job, and that everyone else stays a safe distance from energized parts.
Frequently Asked Questions
Does experience make someone a qualified person under NFPA 70E? No. Experience is valuable but not sufficient. NFPA 70E requires demonstrated skills and knowledge plus hazard-specific safety training for the equipment and task involved. An experienced electrician may still be unqualified for unfamiliar equipment or unfamiliar tasks.
Can a person be qualified for one task but not another? Yes. Qualification is task-specific and equipment-specific. A worker can be qualified to work on one type of equipment or task and unqualified for a different one.
Who decides if someone is a qualified person? The employer designates qualified person status and must verify ongoing competence. Training providers can deliver instruction but cannot confer the designation.
How often must a qualified person be retrained? At least every three years, and sooner if job duties, equipment, or procedures change, or if the worker is found not following safe work practices.
Can an unqualified person work near energized equipment? Only outside the limited approach boundary, or inside it when continuously escorted by a qualified person who has advised them of the hazards. Unqualified persons may never cross the restricted approach boundary.
