OSHA competent person vs qualified person: what's the real difference?

Last updated 2026-07-09

What does OSHA mean by 'competent person'?

OSHA defines a competent person in 29 CFR 1926.32(f) as "one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them." That language lives in the construction standards, and OSHA carries essentially the same wording into its general industry and maritime rules.

Two things carry the whole definition. The person has to actually identify hazards, more than run a checklist. And they have to hold real authority to act. A worker who spots a problem but waits three days for a supervisor to sign off does not meet the definition. Authority is baked in ^[1].

Competent person status is earned through knowledge plus experience. OSHA does not require a degree or a specific credential. A carpenter with ten years in trench excavation can qualify as a competent person for that work. What counts is proven ability to recognize the hazard and the on-site authority to fix it. Formal OSHA training helps build that ability, but training alone is not enough without the authority piece.

The requirement appears in more than two dozen OSHA standards. Excavation inspections (29 CFR 1926.651), scaffold erection and inspection (29 CFR 1926.451), fall protection (29 CFR 1926.502), and confined space entry (29 CFR 1910.146) all pull in a competent person. If your business touches any of those, you need a named, documented competent person before the work starts.

What does OSHA mean by 'qualified person'?

OSHA defines a qualified person in 29 CFR 1926.32(l) as "one who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated his ability to solve or resolve problems relating to the subject matter, the work, or the project" ^[2].

The key word is technical. A qualified person brings verifiable expertise, usually in engineering, structural analysis, electrical systems, or another specialized field. Picture a licensed professional engineer, a certified industrial hygienist, or an electrical engineer with real arc-flash depth. This is not about spotting a problem. It's about designing the solution, running the calculations, and making the technical call.

Qualified person requirements gather in standards built on engineered systems. Crane and derrick operations (29 CFR 1926.1401) need a qualified person to design rigging plans and evaluate ground conditions. Electrical work under the general industry rule (29 CFR 1910.303) needs a qualified person for certain installations. Steel erection (29 CFR 1926.752) needs a qualified person to design and test fall protection for connectors.

In practice, the qualified person is often an outside engineer or specialist you bring in for a specific job. That's fine. OSHA does not require the qualified person to be your employee. They just have to meet the definition and be genuinely involved in the work, more than sign a form from across town.

How are the two definitions different in plain terms?

Here's the split. Competent person is about recognition and authority. Qualified person is about technical knowledge and credentials.

Factor	Competent Person	Qualified Person
Primary OSHA definition	29 CFR 1926.32(f)	29 CFR 1926.32(l)
Core requirement	Identify hazards + authority to correct	Technical knowledge/credentials + demonstrated ability
Credential required?	No, experience can substitute	Yes (degree, cert, or extensive demonstrated expertise)
Day-to-day role	On-site inspection, stop-work authority	Engineering design, system evaluation, calculations
Examples	Site foreman for trenching, scaffold inspector	PE who designs scaffold, electrical engineer for arc-flash
Can one person fill both?	Yes, if they meet both definitions	Yes, if they meet both definitions

One person can be both competent and qualified for the same task. A structural engineer who's on site daily and holds stop-work authority over shoring design meets both definitions at once. That overlap is common in smaller shops. The mistake most small businesses make is assuming the competent person is automatically qualified, or that a qualified engineer on paper automatically has on-site authority. They are separate tests ^[3].

Which OSHA standards require a competent person?

The competent person requirement is more common than most employers realize. A partial list of standards that spell it out:

• Excavation and trenching: 29 CFR 1926.651(k)(1) requires daily inspections by a competent person before each shift and after any hazard-increasing event ^[4].
• Scaffolding: 29 CFR 1926.451(f)(3) requires a competent person to inspect scaffolds before each work shift and after anything that could affect structural integrity ^[7].
• Fall protection: 29 CFR 1926.502(k) requires a competent person to develop and supervise the fall protection plan where conventional systems are infeasible.
• Confined spaces: 29 CFR 1910.146 requires an attendant and entry supervisor with defined competencies, though the exact term "competent person" shows up more in the construction confined space rule at 29 CFR 1926.1204 ^[9].
• Hazard communication: 29 CFR 1910.1200 does not use the phrase but effectively needs someone competent to evaluate chemical hazards. See our guide to hazard communication for how that plays out.
• Lead standard: 29 CFR 1926.62(l)(1)(i) requires a competent person to perform initial exposure assessments ^[12].

If your written safety program covers any of these, it needs to name or describe the competent person for each hazard category. That documentation is what gets checked at inspection time.

Which OSHA standards require a qualified person?

Qualified person requirements cluster where engineering judgment is not optional. The standards that come up most for small and mid-size businesses:

• Cranes and derricks: 29 CFR 1926.1401 defines a qualified person and requires one to design lift plans, evaluate ground bearing capacity, and set assembly procedures for certain equipment ^[8].
• Steel erection: 29 CFR 1926.752(a) requires a qualified person to prepare site-specific erection plans ^[10].
• Electrical safety (general industry): 29 CFR 1910.303(b)(1)(iii) requires a qualified person to approve certain wiring methods.
• Powered industrial trucks: 29 CFR 1910.178 does not use the exact term, but OSHA letters of interpretation have clarified that forklift certification trainers must be qualified by training and experience.
• Respirator fit testing (29 CFR 1910.134): OSHA expects the program administrator to be qualified, and its letters of interpretation confirm this means knowledgeable about the standard's requirements.
• Lockout/tagout (29 CFR 1910.147): requires an authorized employee qualified to perform energy-control procedures, distinct from affected employees who only need awareness training ^[13].

The pattern holds. Whenever OSHA asks someone to make a judgment that could be wrong in a way that kills people, it names a qualified person.

Can the same person be both competent and qualified?

Yes, and in a lot of small businesses one person carries both roles. A licensed structural engineer who is also your site superintendent, holds stop-work authority, and runs daily scaffold inspections meets both definitions at the same time.

The reverse is where businesses get burned. They name a competent person who clearly knows the jobsite but has no engineering background to judge whether a trench shoring design holds up. Or they hire a qualified engineer to stamp drawings, but that engineer has no presence or authority on site, so nobody with real decision power can catch and correct hazards as they happen.

OSHA does not force you to run two separate people. But if one person covers both roles, document it clearly. Your written program should state the individual's qualifications and spell out that they also hold competent person authority, including the power to stop work. That documentation protects you at inspection and makes responsibility obvious.

For businesses building out their written safety programs, the SafetyFolio program generator prompts you to name your competent and qualified persons for each hazard area, which is one of the first things inspectors check.

What happens if you designate the wrong person?

OSHA cites employers for competent person and qualified person failures under the specific standard that requires them, not under a general catch-all. That drives the penalty math.

Excavation alone generates hundreds of competent person citations a year. Trenching and excavation sits consistently among the top-cited construction standards. As of 2024, a serious violation for failing to designate a competent person for excavation can reach $16,131 per violation, and a willful or repeat violation can climb to $161,323 (OSHA adjusts these maximums annually for inflation) ^[5].

Then there's the liability if someone gets hurt. If an unqualified person approved a shoring design that collapsed, the failure to name a properly qualified person becomes evidence of negligence in civil court. Courts and OSHA both look at whether your program named a real person who actually met the definition, or whether you just wrote a name in a box.

The fix is simple. For each activity that requires a competent or qualified person, list the individual's name, their relevant experience or credential, and the specific authority they hold. Review it at least once a year and any time personnel change.

Does an OSHA 30 card make someone a competent person?

No. This is one of the most stubborn misconceptions in workplace safety.

An OSHA 30 card shows someone finished a 30-hour training course covering a broad range of construction or general industry topics. It's a training credential. OSHA 30 is genuinely useful because it builds the base knowledge competent persons need, but the card alone does not confer competent person status.

Competent person status is task-specific and authority-specific. A worker can hold an OSHA 30 card and still not be a competent person for scaffold erection if they've never built scaffolding and have no stop-work authority. Flip it around: a scaffold erector with twenty years in the trade and clear employer-granted stop-work authority can be a legitimate competent person for scaffolding even without an OSHA 30 card.

The OSHA 30 training covers hazard recognition, fall protection, and excavation safety at an awareness level. Real competent person development needs hands-on experience in the specific hazard plus a formal grant of authority from the employer. Think of OSHA 30 as a strong foundation, not the finished house.

Smart employers document their competent persons by noting both the experience record and any formal training completed, including OSHA courses. That combination tells a clearer story than either piece alone.

How should your written safety program document competent and qualified persons?

Your written program should do four things for every hazard category that needs a competent or qualified person.

First, identify the specific standard that applies and the role it requires. Excavation needs a competent person per 29 CFR 1926.651(k)(1). Crane lift plans may need a qualified person per 29 CFR 1926.1401. Write those citations down.

Second, name the individual. Not a job title. A specific named employee, with their title, years of relevant experience, and any credentials (PE license number, certifications, completed training courses). OSHA inspectors have been known to ask to speak with the competent person, then question that person to confirm they actually understand the hazards.

Third, document the grant of authority for competent persons. A signed letter, or a section of your safety program stating that the person can stop work and require corrective action, beats a name in a box every time.

Fourth, include a succession plan, or at least a note on what happens when that person is out. You need a competent person present while the work is happening. If your designated person is out sick, what's the protocol? Some operations halt that work category entirely. That's a legitimate answer and often the right one.

An incident report after a trenching cave-in that shows you had no documented competent person is the worst possible time to find this gap.

Are competent and qualified person requirements different in state-plan states?

OSHA state plans have to be at least as effective as federal OSHA, and they can be stricter. In practice, most state-plan states adopt the same competent and qualified person definitions found in federal standards. California's Cal/OSHA, Washington's L&I, and Michigan's MIOSHA all use language that tracks the federal definitions closely.

Where state plans sometimes split off is in the training requirements that feed competent person status. California's Title 8 requires more specific documented training for certain excavation competent person roles than federal OSHA does. Michigan's MIOSHA has issued extra guidance on who qualifies as a competent person for confined space entry.

If you operate in a state-plan state, check your state's regulations rather than leaning only on 29 CFR. The definitions in this article are the federal baseline. The practical differences are usually modest, but they exist, and a state inspector will cite you under state rules.

What questions should you ask to verify someone actually qualifies?

Before you designate someone, ask these questions to their face. The answers tell you whether the designation is real or just paperwork.

For a competent person:

• What are the specific hazards in this work area that you're responsible for identifying?
• What do you do if you see a condition that's immediately dangerous to life or health?
• Do you have authority to stop work without prior approval from management? Who confirmed that?
• When did you last inspect for this hazard type, and what did you find?

A genuine competent person answers the hazard questions without hesitation and knows exactly what their stop-work authority looks like on the ground. If someone says "I'd have to check with my foreman before stopping work," they do not meet the definition.

For a qualified person:

• What is your specific credential or educational background in this area?
• Can you show me how you'd evaluate this system or condition? Walk me through it.
• What professional standards or codes do you reference when you make these judgments?

A qualified person can show their work. They point to specific technical standards, codes, or analytical methods. If they wave at "general experience" without connecting it to the technical problem in front of them, keep probing before you finalize anything.

These conversations are worth documenting too. A short note in the employee file stating you verified the person's knowledge on a specific date, covering specific topics, helps if OSHA ever questions the designation.

Where can you find more official OSHA guidance on these definitions?

OSHA has published several letters of interpretation that clarify how the agency applies these definitions in real situations. Letters of interpretation are official guidance, not binding regulations, but they show how OSHA compliance officers think.

OSHA's letters of interpretation database, reachable through osha.gov, holds multiple letters on who qualifies as a competent person for trenching, scaffolding, and confined space entry. One frequently cited letter makes clear that an employer cannot designate someone a competent person by job title alone; the individual has to actually hold the required knowledge and authority ^[6].

The OSHA Construction Industry Digest (OSHA Publication 2202) gives a plain-language summary of construction standards, including competent person requirements by activity. It's a free download from osha.gov and worth keeping with your program documentation ^[11].

For general industry, OSHA's compliance directives for specific standards (CPL documents) often include guidance on competent and qualified person requirements. CPL 02-00-150, which governs inspection procedures for fall protection, addresses competent person verification during inspections.

If you're building a written program from scratch and want to catch every role, the SafetyFolio program generator walks through each hazard category and prompts you to document your competent and qualified person designations in the format inspectors look for.

Frequently asked questions

Does OSHA require a competent person to be on site at all times?

Not always in every standard, but many require a competent person present during specific activities. For excavation, 29 CFR 1926.651(k)(1) requires inspection before each shift and after any hazard-increasing event. For scaffold erection and use, the competent person must inspect before each work shift. When the work requiring a competent person is happening, that person generally needs to be physically accessible, more than a phone call away.

Can an owner or manager be the competent person for their own business?

Yes, absolutely. OSHA does not require the competent person to be a non-supervisory employee. An owner or manager with the relevant knowledge who has granted themselves stop-work authority over a hazard area can qualify. The key is documenting that authority and making sure the knowledge is real. An owner naming themselves competent person for excavation should be able to explain soil classification, protective systems, and inspection procedures.

Is a professional engineer automatically a qualified person under OSHA?

Usually yes for work inside their area of licensure, but not automatically for every OSHA standard. A PE licensed in structural engineering typically qualifies for scaffold or shoring design. That same PE would not automatically qualify for electrical arc-flash analysis if their training and experience are not in electrical systems. OSHA's definition requires demonstrated ability specific to the subject matter at hand.

What is the difference between an authorized person and a competent person in OSHA standards?

OSHA defines an authorized person in 29 CFR 1926.32(d) as one approved or assigned by the employer to perform a specific duty. Authorization is about permission. Competence is about knowledge plus hazard-identification authority. A confined space attendant is authorized to monitor entry but may not be the competent person responsible for evaluating atmospheric hazards. The competent person role carries far more responsibility and needs broader knowledge.

How does OSHA verify competent person status during an inspection?

Compliance officers typically ask to meet the designated competent person and put direct questions about the hazards they manage. They may ask the person to walk through a current inspection, describe what they look for, and explain what they'd do if they found a hazardous condition. They also review documentation: your written program, training records, and evidence the person has actually performed inspections. A name on paper without support rarely holds up.

Do you need a separate competent person for each type of hazard?

One person can cover multiple hazard categories if they genuinely hold the knowledge and authority for each. A site supervisor with deep experience in both excavation and scaffolding, plus clear authority to stop work for either, can serve as competent person for both. What you cannot do is name one person competent for every hazard on site as a paperwork shortcut when they clearly lack knowledge or experience in some of those areas.

Can a subcontractor's competent person cover the general contractor's workers?

This is where multi-employer worksite rules come in. On a multi-employer site, OSHA can cite any employer whose employees are exposed to a hazard, regardless of who created it. A subcontractor's competent person has authority over that sub's employees. For the GC's workers, the GC needs its own competent person or a documented arrangement giving the sub's competent person explicit authority over all workers on site. Verbal arrangements here are risky.

Is there a specific OSHA training certificate that certifies someone as a competent person?

No. OSHA does not issue or recognize a single training certificate that confers competent person status. Various private organizations offer competent person courses for specific hazards like trenching or scaffolding, and those can contribute to the knowledge requirement. But OSHA does not endorse or approve specific certifying bodies for the designation. The employer makes the call based on demonstrated knowledge, then grants the required authority.

How often should you re-evaluate your designated competent persons?

OSHA does not set a re-evaluation interval, but best practice is at least annually and any time the person's role changes, they return from extended absence, or standards update. A competent person who was solid three years ago may have gaps if your operations changed or new hazards appeared. Periodic documented check-ins confirming the person still holds the knowledge and authority are a reasonable defense if the designation is ever challenged.

What is the penalty for not having a competent person when OSHA requires one?

OSHA cites the specific standard violated, not a generic competent person rule. For a serious violation of 29 CFR 1926.651(k)(1), failing to have a competent person inspect an excavation, the maximum penalty is $16,131 per violation as of 2024. Willful or repeat violations can reach $161,323 per violation. OSHA adjusts these maximums annually. The actual penalty depends on size, good-faith efforts, history, and severity.

Does the qualified person requirement apply to general industry or just construction?

Both. The 29 CFR 1926.32(l) definition sits in the construction standards, but the qualified person concept runs throughout general industry standards in 29 CFR 1910 too. Electrical installation requirements, crane operation, respirator program administration, and lockout/tagout procedures all reference qualified person standards in the general industry rules. The underlying concept, demonstrated technical expertise, applies equally in both sectors.

Can an OSHA 10 or OSHA 30 course be used to document competent person training?

It can be included as part of a competent person's training file, but it cannot stand alone as proof of competency. OSHA 10 and OSHA 30 are general awareness courses. For competent person documentation you also need evidence of task-specific experience and knowledge: past inspection records, job history, any hazard-specific training completed, and documentation of the authority grant. The OSHA 30 card is a useful supporting document, not a sufficient one.

What written documentation should you keep for your competent and qualified persons?

At minimum: a written designation naming the individual, the specific standards and hazard areas they cover, their relevant experience and credentials, documentation of any formal training completed, a clear statement of their stop-work authority (for competent persons), and any third-party credentials or license numbers (for qualified persons). Keep this in your written safety program and update it when personnel change. Inspection records signed by the competent person also build your paper trail.
