OSHA Inspections: What to Expect and How to Respond
The compliance officer arrives without an appointment: opening conference, walkaround, employee interviews, document demands — and every step has rules for the employer's side, from Fourth Amendment rights to the 15-day contest deadline.

What brings OSHA to the door
Inspections follow a priority ladder: imminent danger reports first; fatalities and catastrophes (from the 8/24-hour reports) second; employee complaints and referrals third — the most common trigger in practice; and programmed inspections of high-hazard industries under national and local emphasis programs last. Two implications. Because complaints drive inspections, an internal reporting culture that actually fixes hazards is inspection prevention — employees call OSHA when nobody inside listens. And because complaint inspections are scoped to the complaint, knowing the trigger tells you the lawful boundaries of the visit.
The opening: credentials, scope, warrants
Have a written protocol so the front desk knows the first three moves: verify the compliance officer's credentials, notify the designated company representative, and convene the opening conference — where the officer states the reason and scope. The Fourth Amendment applies (Marshall v. Barlow's): you may insist on a warrant, which OSHA will usually obtain; most employers instead consent and manage scope, objecting on the record to expansions beyond the stated basis. For a complaint inspection, ask for the complaint (you're entitled to a copy, names redacted). Designate one person to accompany the officer everywhere, mirror every photo and note, and log every document handed over — the company's file of the inspection should be as complete as the government's.
The walkaround and interviews
The walkaround follows the scoped route — not a facility tour; take the direct path to the relevant area, because plain-view hazards anywhere along the way are citable. Fix what can be fixed on the spot, photographed and timestamped: immediate abatement supports good-faith penalty reductions. The officer may interview non-management employees privately — that's their right, and interference or later retaliation is a separate violation; tell employees beforehand, factually, to answer truthfully. Management interviews bind the company: managers may and should have counsel or a representative present, answer what's asked, and skip speculation. Document requests center on the 300-series records, written programs and training logs — produce them organized and complete, nothing more.
Citations and the 15-day clock
Citations arrive by mail with classifications and proposed penalties (the amounts and categories in the penalties guide), an abatement date per item, and a posting duty — each citation posts at or near the violation site for three working days or until abated. Then the only unforgiving deadline in the process: 15 working days to file a Notice of Contest or request an informal conference with the area director — where classifications, penalties and abatement dates are routinely negotiated. Miss the deadline and the citation becomes a final order no court can reopen. Contest strategically: an uncontested citation is a prior violation for repeat-classification purposes for five years, so cheap settlements today can price future citations at ten times the rate.
