Inspections, Audits, and Corrective Action

Inspections vs. Audits

The STSC distinguishes two related but different activities:

• An inspection is a frequent, focused check of physical conditions and behaviors against a standard — "Is this scaffold safe right now?"
• An audit is a broader, periodic evaluation of the entire safety program and its management systems — "Does our program meet OSHA's Recommended Practices and is it working?"

Think of inspections as the daily/weekly heartbeat and audits as the annual physical. Both belong to the Check phase of the PDCA cycle. A distractor that uses "audit" to mean a single equipment check, or "inspection" to mean a full-program review, is testing this distinction.

What a Program Audit Evaluates

A safety-program audit looks past physical conditions to the system that produces them. A thorough audit asks:

• Are the seven program elements (leadership, participation, hazard ID, control, training, evaluation, coordination) present and functioning?
• Are records — training, inspections, JHAs, 300 Logs — complete and current?
• Do leading and lagging metrics show improvement, and are corrective actions actually closing?
• Are roles (competent persons, qualified persons) properly designated and trained?

Audits can be internal (self-assessment) or third-party. The output is a gap analysis that feeds the Act phase of PDCA, driving changes to the program itself rather than to a single piece of equipment.

The Internal Inspection Duty: 1926.20(b)(2)

The employer's own inspection duty comes from 29 CFR 1926.20(b)(2): accident-prevention programs must provide for frequent and regular inspections of the jobsite, materials, and equipment, performed by competent persons. The competent person must be able to both identify hazards and correct them — which is why this duty cannot be delegated to a clerk with no authority.

Inspection Frequencies Set by Specific Standards

Many 1926 subparts impose their own inspection cadence. Memorize the most-tested ones:

Note the recurring theme: the competent person is the named inspector for scaffolds, excavations, and most hazard categories.

Conducting an Effective Internal Inspection

A disciplined inspection follows a repeatable routine:

1. Use a checklist built from the applicable 1926 standards and the site JHAs.
2. Walk the work as performed, not just storage areas — observe behaviors and conditions.
3. Document findings with location, hazard, photo, and the standard violated.
4. Classify severity so the worst hazards are fixed first.
5. Assign corrective action with a responsible person and due date.
6. Verify closure — re-inspect to confirm the hazard is actually gone.

An inspection that lists hazards but never closes them is theater. The exam consistently rewards the answer that ends in verified corrective action.

The OSHA Enforcement Inspection (Four Stages)

When OSHA itself inspects, the process is predictable and testable. The four stages, in order:

1. Opening conference — the compliance officer presents credentials and explains the scope to the employer and an employee representative.
2. Walkaround — the officer tours the site; the employer and a worker representative may accompany.
3. Closing conference — the officer reviews apparent violations and discusses abatement.
4. Citations and penalties — issued by mail; OSHA must issue any citation within 6 months of the violation.

OSHA inspection priorities, highest first, are: imminent danger, fatality/catastrophe, complaints/referrals, programmed inspections (e.g., National Emphasis Programs), and follow-ups. A question asking what OSHA addresses first wants imminent danger.

Multi-Employer Citations on Construction Sites

Because construction sites are multi-employer, an OSHA inspection can result in citations to more than one company. The four roles — creating, exposing, correcting, and controlling employer — each carry potential liability. The controlling employer (usually the general contractor) is expected to exercise reasonable care to detect and correct subcontractor hazards, which makes general-contractor inspection programs essential.

Corrective Action: Closing the Loop

The Act phase converts findings into fixes. A complete corrective action has three parts: a responsible person, a specific due date, and verification that the action worked. Where possible, the corrective action should move up the hierarchy of controls — replacing a temporary administrative fix with a durable engineering control — and address the root cause, not just the symptom.

A supervisor who knows of a hazard and fails to correct it can face personal liability if a worker is injured, which is why prompt abatement authority is built into the competent-person definition.

Interim vs. Permanent Abatement

Not every hazard can be permanently fixed the moment it is found. The standard practice is to apply an interim control immediately — barricade the area, tag out the equipment, remove workers from the trench — and then implement the permanent corrective action as soon as feasible. The exam-correct answer never leaves workers exposed while the permanent fix is pending; it pairs an immediate interim measure with a tracked permanent solution.

Behavior-Based Observations

Many construction programs add safety observations (behavior-based safety, or BBS) on top of condition inspections. Trained observers watch how work is actually performed, give immediate positive or corrective feedback, and log at-risk behaviors as leading-indicator data. BBS works only in a no-blame culture where workers trust that observations drive coaching, not discipline; otherwise reporting dries up. Observations complement, but do not replace, the competent-person inspections required by 1926.

Common Inspection and Audit Mistakes

• Confusing a narrow inspection with a full program audit.
• Assigning inspections to someone without authority to correct hazards.
• Documenting findings but never verifying they were closed.
• Forgetting standard-specific frequencies (scaffold per shift, excavation daily/after rain).
• Mixing up OSHA's inspection stages or the 6-month citation window.
