Competent Person
An OSHA term for a worker who is capable of identifying existing and predictable hazards in a specific area of work and who has the authority to take prompt corrective action to eliminate them, a designation tied to demonstrated knowledge and authority, not a job title or a certificate.
Why it matters
Several of OSHA's highest-consequence standards, such as excavation, scaffolding, and fall protection, specifically require a designated competent person to inspect conditions and make judgment calls, rather than relying on a generic checklist anyone could apply. Naming someone competent person for an area they aren't actually qualified for defeats the entire purpose of the requirement.
On a real project
Before workers enter a trench deeper than five feet, the crew's designated competent person inspects the soil conditions and confirms the protective system in place is adequate, a judgment call OSHA specifically requires that named individual to make.
Who this matters most to
An Equipment Operator often works directly under a competent person's direction when placing shoring or trench protection. A Safety Manager is typically the one who formally designates competent persons across a project and verifies their inspections are actually happening and documented.
Where this goes wrong
A company designates a crew lead as the competent person for excavation work mainly because of seniority, without confirming they actually have the training to evaluate soil conditions. An inspection that should have caught an inadequate protective system gets signed off anyway, because the person signing it wasn't equipped to catch the problem in the first place.
