What Triggers an OSHA Inspection?
OSHA prioritizes inspections in this order, from highest to lowest urgency:
- Imminent danger situations — A hazard that could cause death or serious harm imminently. Reported via a complaint or observed during a prior inspection.
- Fatality and hospitalization investigations — Any work-related fatality must be reported to OSHA within 8 hours. Any in-patient hospitalization, amputation, or loss of an eye must be reported within 24 hours. These automatically trigger an inspection.
- Employee complaints — Employees (and former employees) can file complaints online, by phone, or by mail. OSHA can conduct an inspection based on a complaint without disclosing the complainant's identity. Many employers are surprised to learn that a complaint even existed.
- Referrals — Other government agencies, media reports, or community members can refer hazards to OSHA. A nearby business that OSHA already inspected may result in nearby facilities being visited too.
- Programmed (targeted) inspections — OSHA targets high-hazard industries for planned inspections. If your industry or facility type is on OSHA's current targeted list (based on illness and injury rates), you may be selected even without a complaint or incident.
- Follow-up inspections — After issuing citations, OSHA may return to verify abatement. Facilities with prior citations are at higher risk of re-inspection.
The takeaway: for manufacturers in high-hazard SIC codes, a programmed inspection can happen without any triggering event. Being "under the radar" is not a compliance strategy.

What Happens When an Inspector Arrives
An OSHA Compliance Officer (CO) will present credentials upon arrival. You have the right — and are generally advised — to ask to see credentials and confirm the visit is legitimate. From there, an inspection typically follows three phases:
| Phase | What Happens | What You Should Do |
|---|---|---|
| Opening conference | The CO explains the reason for the visit, the scope, and the process. They will request documents — your OSHA 300 Log, written programs, training records. | Have a designated company representative present. Notify your EHS manager and legal counsel if you have one. Don't volunteer information beyond what's asked. |
| Walkaround | The CO inspects the facility. They may take photos, videos, measurements, and samples. They may interview employees privately. | Accompany the inspector at all times. Document what they photograph and measure. Correct any obvious minor hazards (housekeeping, missing guards) immediately if safe to do so — showing good faith matters. |
| Closing conference | The CO reviews preliminary findings. They do not typically issue citations on-site — those come later by certified mail, usually within 6 months. | Ask clarifying questions about their observations. Request copies of any documents they took. Take notes on everything discussed. |
Employees have the right to speak with an inspector privately. You cannot coach employees on what to say, and you cannot retaliate against employees for speaking with OSHA. If you create a culture where employees trust internal safety processes, they're far less likely to file complaints or say something damaging during a walkaround interview.
Common Citations at Small Manufacturing Facilities
Based on OSHA enforcement data, small manufacturers most frequently receive citations in these areas:
- Lockout/Tagout (29 CFR 1910.147) — Missing machine-specific procedures, inadequate employee training, no annual audit documentation
- Machine guarding (29 CFR 1910.212) — Unguarded point-of-operation, removed guards, inadequate guarding on rotating parts
- Hazard communication (29 CFR 1910.1200) — Missing or outdated SDS, unlabeled containers, no documented training
- Electrical hazards (29 CFR 1910.303) — Open panels, exposed wiring, missing covers
- Walking/working surfaces (29 CFR 1910.22) — Obstructed exits, blocked aisles, unguarded floor openings
Willful violations (where OSHA determines you knew about the hazard and chose not to fix it) carry penalties up to $161,323 per violation as of 2026. Repeat violations carry the same ceiling. Serious violations typically run $16,131 per violation. Penalty amounts are adjusted for employer size, good faith, and history — small employers generally receive reductions, but citations still generate mandatory abatement timelines and create liability exposure.
7 Steps to Prepare Before an Inspection
Conduct a self-inspection using OSHA's top violations as your guide
Walk your facility using the same framework an OSHA inspector would use. Focus first on the areas most commonly cited in your industry: machine guarding, LOTO, electrical, housekeeping, and HazCom. Write down what you find and create a corrective action log with assigned owners and target dates.
Get your written programs in order
Every required written program (HazCom, LOTO, respiratory protection, emergency action plan, PPE hazard assessment, etc.) must exist, be current, and be accessible to employees. "Accessible" means workers can actually find it, not that it lives in a binder in your office. Review each program for accuracy — if your chemical inventory or equipment lineup has changed, update the programs to match reality.
Audit your training records
For every required training (HazCom, LOTO, forklift, respiratory protection, fall protection, emergency response, etc.), you need documented records: who was trained, by whom, on what date, and on what content. If you have employees without training records — even if they were trained — that's a citation waiting to happen. Conduct and document refresher training for any gaps.
Review your OSHA 300 Log for accuracy
Inspectors will review your injury and illness records. Verify that all recordable incidents have been logged within the required 7-day window. Confirm you haven't over-recorded (first aid cases don't belong on the 300 Log) or under-recorded (work-related injuries require recording even if medical treatment was minor). The 300A summary must be signed and dated by a company executive.
Fix the visible stuff
Walk the floor with fresh eyes and fix housekeeping, missing labels, blocked exits, and obvious guarding issues before they become low-hanging-fruit citations. Inspectors use the walkaround to assess your overall safety culture. A facility that looks like it cares about safety gets the benefit of the doubt on borderline issues. One that looks neglected doesn't.
Designate and brief your inspection team
Decide in advance who will meet the inspector, who will accompany them on the walkaround, and who will gather requested documents. Brief this team on their role: answer truthfully, don't volunteer unnecessary information, take notes on everything the inspector photographs or measures, and stay with the inspector at all times during the walkaround. Having a calm, organized point of contact signals good faith.
Build a corrective action tracking system
If you identified hazards in your self-inspection, create a formal corrective action log: what was found, who owns the fix, and when it will be resolved. If an inspector asks about a known hazard and you can show it's on an active corrective action plan with a target date, that demonstrates good faith — which OSHA considers when determining citation severity and penalty amounts.
Good faith credit: OSHA applies a 25% penalty reduction for employers that demonstrate good faith — defined as having a proactive safety and health program. Self-inspections, corrective action logs, and documented training programs all contribute to this determination.
After the Inspection: Responding to Citations
If OSHA issues citations (typically by certified mail 1–6 months after the inspection), you have options. You can abate the cited hazard, pay the penalty, and close the citation. Or you can contest the citation within 15 working days of receipt if you believe the citation is incorrect, the proposed penalty is unreasonable, or the abatement timeline is infeasible.
Many small employers successfully negotiate informal settlements with OSHA that reduce penalties in exchange for immediate abatement commitments. This is often the practical path forward for smaller violations.
The best outcome, of course, is being prepared enough that the inspection results in a clean walk — or at most, a few minor paperwork items. That starts with the self-assessment before they ever arrive.
