Does OSHA Certify Competent Persons? No — What an Inspector Actually Asks to See

There is no such thing as an "OSHA-certified competent person." Search "competent person certification" and you will find hundreds of 8-hour courses selling exactly that phrase. But OSHA does not certify competent persons, does not keep a register of them, and does not score them. A training certificate proves someone sat through a course. It does not make them your competent person — and in an inspection, handing over a certificate when the officer asked "who is your competent person for this trench, and what can they do about a hazard?" answers neither question.

At a glance: OSHA does not certify competent persons — the employer designates them. The definition at 1926.32(f) has two prongs: able to identify the hazards, and authorized to take prompt corrective measures. The duty comes from the activity standards — daily trench inspections (1926.651(k)(1)), soil classification (Subpart P App. A(c)(1)), the shallow-excavation examination (1926.652(a)(1)(ii)), program inspections (1926.20(b)(2)), silica (1926.1153(g)(4)). What proves it: the signed designation, the written basis of competency, the written stop-work authority, and the designee's acknowledgment. No federal expiration date exists. OSHA does not certify competent persons and keeps no register of them: the employer designates a competent person, who under 29 CFR 1926.32(f) must be capable of identifying hazards and authorized to take prompt corrective measures, and what proves the designation is a signed letter, a written basis of competency, written stop-work authority, and the employee's acknowledgment; no OSHA provision sets an expiration date or an annual renewal for it.

What "competent person" actually means — and the half everyone forgets

The construction definition lives at 29 CFR 1926.32(f) — and note that it is a definition, not a standalone requirement. It has two prongs:

1. Capability — "capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees";
2. Authority — "who has authorization to take prompt corrective measures to eliminate them."

The second prong is the one that fails in real inspections. A foreman who can spot a cave-in risk but has to phone the office before stopping the excavator is not a competent person under the definition — no matter how many certificates are in the binder.

The duty to have competent persons doing specific jobs comes from the activity standards themselves: daily excavation inspections under 1926.651(k)(1), soil classification under Subpart P Appendix A, paragraph (c)(1), the examination of the ground that exempts an excavation under 5 feet from protective systems under 1926.652(a)(1)(ii), frequent and regular inspections under 1926.20(b)(2), the silica competent person under 1926.1153(g)(4) — not from the definition.

The four documents that prove a designation

When the question comes, from an OSHA compliance officer, a general contractor's safety manager, or a plaintiff's attorney two years later, these are the four pieces that answer it:

1. A signed designation letter. The employer names the person, the activity, and the jobsite scope, and signs it. This is the act of designation itself — the thing the training certificate is not.
2. A written basis of competency. Not a checkbox: the training, experience and knowledge that make this person capable for THIS activity. For excavation: soil classification training plus years of trenching supervision — the Appendix A knowledge the standard expects them to apply.
3. A written scope of authority. The sentence that satisfies the second prong: authorized to stop work and take prompt corrective measures, including removing employees from the hazard area, without prior approval. If that sentence is not written down, expect the inspector to test it in interviews.
4. The employee's acknowledgment. A designation the designee doesn't know about protects no one. A dated acknowledgment closes the loop. On silica jobs the crew needs the name too: each covered employee must be able to identify the designated competent person (1926.1153(i)(2)(i)(E)).

None of these four documents is prescribed by 1926.651(k)(1), 1926.1153(g)(4), or 1926.20(b)(2); they are how an employer proves a designation those rules assume.

Excavation: where this gets tested first

Trenching is where competent-person paperwork meets its inspector most often — the background is in our trenching and excavation safety guide and the trench geometry deep-dive. Under 1926.651(k)(1), a competent person inspects the excavation, the adjacent areas and the protective systems before the start of work and as needed through the shift, and again after a rainstorm or any other hazard-increasing event — the rule adds that these inspections "are only required when employee exposure can be reasonably anticipated," which is the sentence that separates an open trench nobody enters from one with a crew in it. Under Subpart P Appendix A(c)(1), classifying the soil as Stable Rock, Type A, B or C is the competent person's call, and under 1926.652(a)(1)(ii) so is the examination of the ground that lets an excavation under 5 feet go without a protective system. Two direct consequences:

• If your inspection record is signed by someone with no designation, or with a lapsed one, you have documented your own gap.
• The designation and the inspections should be linked records, not two binders that have never met.

How long does a designation last? There is no federal answer — and that's the point

The training industry sells annual "competent person renewals" with real conviction. Before budgeting for one, look for the requirement: after reading 1926.32, 1926.20, 1926.21, 1926.650, 1926.651 and 1926.652 in full, no provision sets a validity period or a periodic renewal for a competent-person designation. Not one year, not three, not any.

That is not a loophole; it is how the definition works. Competence under 1926.32(f) is a present-tense quality: the person is capable of identifying the hazards and has the authority to act, on the day they classify the soil. What the employer must be able to prove is that the person is competent now — not that a certificate was stamped less than twelve months ago. A designation signed four years ago for a supervisor who has classified soil every week since is in better shape than one signed last month for someone who has never set foot in the trench.

So treat a review date as what it is: your company's own discipline, and a good one — people change roles, standards get revised, skills go stale. Put it in writing as a company policy. Just never write "expires per OSHA" on it, because no such clock exists, and an inspector who asks "where does OSHA require this renewal?" should not catch your paperwork inventing a rule.

In HazComFast this distinction is built into the words on the screen: a designation past its review date is labeled "Review Due", not "Expired," because nothing federal has expired, and it stops showing as Active. In the JHA, incident, silica, and confined-space permit forms it stays visible but greyed out and marked Review Due, so the crew sees why that name can't be picked today instead of watching it silently vanish. Thirty days ahead, a banner on the designations screen counts the reviews coming due, so renewal gets decided at the desk.

How HazComFast keeps designations honest

In HazComFast, a designation records all four pieces: the signed letter (stored privately, opened by signed URL only), the basis of competency (a required text; the form refuses fewer than 40 characters), the verbatim scope of authority, and the acknowledgment date. The regulatory basis is filled by the server from the activity; for excavation: 1926.651(k)(1); 1926.652(a)(1)(ii); Subpart P App. A(c); 1926.20(b)(2). And the link to the field is built into the permit: the excavation permit's competent-person menu offers only excavation designations valid that day, for that jobsite or the whole organization, so a designation under review or revoked cannot be picked.
