An OSHA "competent person" is someone who can spot the hazards on a job and has the authority from the employer to stop work and fix them on the spot. It is a specific legal term, not a compliment. Trenching, scaffolds, fall protection, silica, and more all require a designated competent person before the work goes ahead, and if there is not one, the job is out of compliance no matter how careful everyone is being. The two parts that matter are knowledge and authority: knowing what is dangerous, and being allowed to do something about it. This is federal OSHA in 2026.
The two-part definition
OSHA defines a competent person, at 29 CFR 1926.32(f), as one who is:
- Capable of identifying existing and predictable hazards in the surroundings or working conditions that are unsanitary, hazardous, or dangerous to workers, and
- Authorized to take prompt corrective measures to eliminate them.
Both parts are required. A veteran who knows a trench is unsafe but cannot halt the dig is not a competent person for OSHA's purposes, because they lack the authority. A supervisor with authority who cannot recognize the hazard is not one either, because they lack the knowledge. It takes both, in the same person, on that job.
Competent person is not the same as qualified person
These two terms get mixed up, and they mean different things:
- A competent person identifies hazards and has authority to correct them. Think of the trench inspection, the daily scaffold check, the fall-protection walk-through.
- A qualified person has a recognized degree, certificate, or extensive knowledge and training that lets them solve or design something, like an engineer designing a trench protective system deeper than 20 feet, or someone designing a fall-arrest anchor.
Some tasks need a competent person, some need a qualified person, and a few need both. Do not assume one covers the other. The definitions are next to each other in the same section: competent at 1926.32(f), qualified at 1926.32(m), where qualified means someone 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."
Where a competent person is actually required
"Trenching, scaffolds and more" is where most explanations stop. Here is the list with the sections, so you can check any row in one hop and, more usefully, work out whether the job in front of you needs one today:
| Work | What the standard requires | Section |
|---|---|---|
| Excavations | Inspections before work starts and as needed through the shift, and after every rainstorm or other hazard-increasing occurrence | 1926.651(k)(1) |
| Scaffolds | Inspected for visible defects before each work shift, and after any occurrence that could affect structural integrity | 1926.451(f)(3) |
| Ladders | Inspected for visible defects periodically and after any occurrence that could affect safe use | 1926.1053(b)(15) |
| Silica | A designated competent person makes frequent and regular inspections of job sites, materials and equipment to implement the written exposure control plan | 1926.1153(g)(4) |
| Confined spaces | Identifies all confined spaces before work begins, and identifies which of them are permit spaces | 1926.1203(a) |
| Cranes | A visual inspection begun before each shift the equipment is used | 1926.1412(d)(1) |
| Fall protection | Designated as the safety monitor where a safety monitoring system is used | 1926.502(h)(1) |
Two things fall out of reading them together. The frequency is not the same rule twice. Scaffolds and cranes are every shift; excavations are before work AND again as conditions change; ladders are periodic plus after an incident. And most of these are inspections, not paperwork. The competent person is a person who looks at the thing, on the day, and can stop it.
Where OSHA requires one
A competent person has to be designated for a long list of construction activities, including:
- Excavation and trenching: daily inspections before each shift, after rain, and after any change (1926.651).
- Scaffolding: inspection before each work shift and after any event that could affect it (1926.451).
- Fall protection: selecting systems and inspecting equipment.
- Ladders, cranes, steel erection, silica, and demolition, each with its own competent-person duties.
The pattern is consistent: high-hazard work needs someone qualified looking at conditions before work starts and again when things change, not after an incident.
How you become one and what it is not
- The employer designates you. Competent person is a role your employer assigns, backed by real authority, not a title you give yourself.
- Training makes the knowledge real. Federal OSHA does not issue a "competent person card," but you cannot identify hazards you were never taught to see, so competent-person training courses (trenching, scaffold, fall protection) exist for exactly this and are widely expected. Some states and many general contractors require specific training.
- It is not a formality. Naming a competent person who is off-site, untrained, or has no power to stop work does not meet the standard. The whole point is a real person, on the job, who can and will halt it.
Common questions
What is an OSHA competent person?
A competent person is someone who can identify the hazards on a job and is authorized by the employer to stop work and correct them promptly. It is a specific term defined at 29 CFR 1926.32(f), and it requires both parts: the knowledge to spot the danger and the authority to act on it. Trenching, scaffolds, and fall protection all require a designated competent person before work proceeds.
What is the difference between a competent person and a qualified person?
A competent person identifies hazards and has authority to correct them; a qualified person has a degree, certificate, or extensive training to design or solve something. A competent person inspects a trench or scaffold daily; a qualified person, often an engineer, designs a trench protective system over 20 feet deep or a fall-arrest anchor. Some tasks need one, some need the other, and a few need both.
Do you need a certificate to be a competent person?
Federal OSHA does not issue a competent-person card or certificate; the employer designates the role. But you cannot identify hazards you were never trained to see, so competent-person training courses for trenching, scaffolds, and fall protection are widely expected and sometimes required by states or general contractors. The designation only counts if it comes with real authority to stop work.
Does every construction job need a competent person?
Many high-hazard activities require a designated competent person, and if the work involves one of them, you need one before it starts. Excavation and trenching, scaffolding, fall protection, ladders, cranes, and demolition all carry competent-person duties. If the required competent person is not present, trained, and empowered to act, the job is out of compliance regardless of how careful the crew is.
The honest bit
- The competent-person definition and the standards that require one are federal OSHA in 2026 under 29 CFR 1926. Verify current requirements at osha.gov.
- About 22 states run their own OSHA program and some require specific competent-person training. See Working in Your State.
- This is general guidance, not training. Being named a competent person without the knowledge or the authority to back it up helps no one, so get the proper training for the work you supervise.
