What is an OSHA competent person?

In OSHA construction rules, a “competent person” is someone capable of identifying existing and predictable hazards in the surroundings or working conditions, and authorized to take prompt corrective measures to eliminate them. Both capability and real authority are essential. The federal definition is in 29 CFR 1926.32(f). A job title, training certificate or employer's name on a roster does not by itself show that the person can assess the particular scaffold, excavation or confined space and stop or correct unsafe work.

The term appears in many task-specific OSHA provisions. Its practical meaning depends on what hazard the provision asks the person to evaluate. One supervisor may be competent for an excavation inspection but not for scaffold erection, structural design or electrical testing. The employer must select people with the relevant knowledge and experience, define their scope, and give them authority to act. OSHA's course FAQ says that taking an OSHA Training Institute Education Center course does not itself qualify a person as a competent person. Do not advertise an “OSHA competent-person card” as universal government certification.

The two-part test: recognize and correct

1. Can the person identify the hazards for this task?

A competent person must know what existing and predictable hazards look like. In a trench, that may involve soil conditions, protective systems, water, utilities, spoil placement and changes after rain. On a scaffold, it involves components, loading, foundations, access, bracing and signs of damage. In a construction confined space, it involves recognizing spaces and evaluating whether permit conditions exist. Generic construction experience helps, but it does not replace topic-specific knowledge.

Assess a proposed person by asking what they would inspect, which conditions require immediate removal of workers or stopping work, what standard applies, and how they would arrange a safe correction. Review their relevant training, field experience, equipment familiarity and ability to recognize new conditions. The employer should document a task-specific selection decision, not merely file a course certificate.

2. Can the person take prompt corrective measures?

A person who spots a collapsing trench wall but must wait hours for a distant manager to authorize stopping work lacks the practical authority contemplated by §1926.32(f). Give the person clear power to stop entry or use, move people away, require a protective system or other control, and escalate an engineering issue to the proper qualified professional. Authority does not mean the competent person can design or approve work beyond their skills or a rule's separate engineer requirement.

A sample designation might say: “Alex is designated to inspect the named excavation and adjacent area under §1926.651(k), may prevent entry and require correction of identified hazards, and must refer protective-system design outside the manufacturer's/tabulated-data scope to the designated engineer.” That is clearer than “Alex — competent person” written next to every task on a site.

Where the role matters: three concrete examples

Excavations

Under 29 CFR 1926.651(k), a competent person makes daily inspections of excavations, adjacent areas and protective systems where exposure can reasonably be anticipated. The rule calls for inspection before work and as needed through the shift, including after a rainstorm or other hazard-increasing event. If the inspection finds evidence of possible cave-in, failure of a protective system, hazardous atmosphere or other hazardous condition, exposed employees must be removed until necessary precautions are taken. An inspection entry that simply says “trench safe” without recognizing a new seepage line or a moved spoil pile is not an adequate field decision.

A competent excavation inspector needs knowledge of soil and protective systems relevant to the job. If a design exceeds the available tabulated data or requires a registered professional engineer under a specific provision, competence to inspect does not grant design authority. Document who checks the actual excavation and when reassessment is triggered.

Scaffolds

29 CFR 1926.451(f)(3) requires a competent person to inspect scaffolds and their components for visible defects before each work shift and after an event that could affect structural integrity. Other scaffold provisions assign competent-person duties for erection, moving, dismantling or alteration, and for particular fall-protection/access decisions. The person needs knowledge of the scaffold system actually used. An inspection from the ground of a scaffold whose connections or foundation have changed may not answer the relevant hazard question. OSHA's scaffold enforcement guidance recognizes that more than one competent person may be needed for different aspects of scaffold work.

A competent-person inspection does not replace an engineered design when a rule requires one. Nor does a contractor's scaffold tag transfer every duty to the next employer; identify the responsible inspector, work shift and any changes before use.

Confined spaces in construction

Under 29 CFR 1926.1203(a), before starting work at a site, each employer must ensure a competent person identifies all confined spaces in which its directed employees may work and identifies which are permit spaces, considering and evaluating the elements of the space, including testing when necessary. That is a classification task, not merely a sign-check. If entry into a permit space is planned, additional program, permit, trained-role, testing and rescue rules apply. The competent person's initial evaluation is not an entry permit and does not authorize workers to enter a space with unknown conditions.

For a construction project with multiple employers, communicate space classifications and hazards to those who may be affected. A change in process, materials or access can require renewed evaluation. The OSHA construction FAQ explains the scope and initial evaluation. General-industry confined-space entry is governed by a separate provision, §1910.146.

Competent person versus qualified person, authorized person and inspector

OSHA's construction definitions distinguish an authorized person, assigned or approved to perform specific duties, and a qualified person, who has demonstrated ability to solve or resolve subject-matter problems through a recognized degree/certificate/professional standing or extensive knowledge, training and experience. A competent person is defined by hazard recognition plus authority for prompt corrective action. These terms can overlap in one individual, but they are not interchangeable labels.

For example, a scaffold competent person may inspect and direct certain field work, while a registered professional engineer may be needed for a specific design. A qualified electrical worker has a separate training/work-practice meaning under electrical standards. The exact rule tells you which role is needed, and a job may need several of them. Do not use “competent person” as a blanket substitute for an engineer, entry supervisor, qualified electrician or licensed professional.

Nor is every “inspector” a competent person in the OSHA sense. A person might check a daily housekeeping list without authority to stop a hazardous task. Conversely, a competent person may have formal inspection duties under a specific standard. Write down the actual responsibility rather than assume the title conveys it.

Does OSHA issue a competent-person certificate?

There is no universal OSHA card that automatically appoints a competent person across all construction tasks. OSHA's Training Institute FAQ explicitly says its courses do not by themselves qualify a student. Training providers may issue course completion documents; those can be useful evidence of instruction, but the employer still evaluates the person's ability for the relevant hazards and gives authority to correct them. A certificate for scaffolds does not establish excavation competence, and a recent course without field ability may be insufficient.

If a client asks for “competent-person cards,” clarify whether it wants a training record, employer designation, experience evidence or a scheme-specific credential. Provide truthful records. Do not describe a private-provider course as an OSHA-issued license.

How to select, designate and support the role

1. List the provisions that apply to the planned work. Include the exact task, location, equipment, shift and State Plan. The construction definition is a starting point; specific sections may add duties.
2. Check capability against actual hazards. Review training, experience, equipment knowledge and a practical walkthrough. Ask the candidate to identify stop conditions and safe corrective measures.
3. Grant real authority. Put stop-work, exclusion, correction and escalation powers in the person's role and tell supervisors and crews. Supply barriers, protective-system resources and technical support.
4. Set coverage and handover. A competent person who is absent cannot perform a required pre-shift inspection. Name alternates who are themselves qualified for the task.
5. Record the decision. Keep a concise designation with task scope, evidence, limits, date and reviewer. Add inspection records where the task rule or employer system requires them.
6. Reassess when conditions change. New equipment, soil, scaffold type, work phase or incident may exceed the person's competence. Get additional training, specialist support or a different designee.

Example designation record: Work type [ ]; applicable OSHA/State Plan provision [ ]; site/assets [ ]; designated person [ ]; demonstrated knowledge/experience [ ]; authority to stop/correct [ ]; decision limits [ ]; effective dates/shifts [ ]; alternate [ ]; approver [ ]; review trigger [ ]. This is an employer management record, not an OSHA-issued certification.

Common mistakes

• Confusing a course with legal competence. A training record is evidence, not the complete test.
• Naming one competent person for every site hazard. Verify subject-specific knowledge and practical coverage.
• Giving responsibility without authority. A person unable to stop work or secure a correction cannot fulfill the role.
• Treating “competent” as “qualified engineer.” Some designs or technical decisions are assigned to a separate professional.
• Using a form as proof of field inspection. Check the actual scaffold, excavation or space when the rule requires it, and act on findings.
• Ignoring change triggers. Rain, a shifted scaffold, a newly opened pit or new process material can invalidate yesterday's assessment.

A US-specific Complys product link should be added only after its route and implementation are verified. The observed US OSHA compliance page is a candidate for storing role, training and inspection evidence, but this writer pass did not verify a competent-person designation workflow or any ability to certify skill. The live US prequalification article mentions “competent-person cards”; its wording should be checked and, if it implies a universal OSHA credential, corrected during separate whole-owner QA. This article's source-checked explanation does not clear that host.
