Run a Mock OSHA Inspection Before the Real One Hits

Picture the call. A compliance officer is standing in the front office at one of your sites, and the site lead is asking you where the OSHA 300 log lives. You're three states away, the binder is in somebody's truck, and the forklift training records are sitting in an old supervisor's email.

Nobody did anything wrong on purpose. The crew there runs good work every day, and the site lead knows that floor better than anyone. What they haven't done is practice the visit. A mock OSHA inspection is how you give them that practice, on a day you pick, with time left to fix what you find.

Why a Mock Beats Waiting for the Real Visit

OSHA's own inspections fact sheet says it plainly: inspections normally happen without advance notice. There's no schedule of annual OSHA inspections you can plan your year around. The visit comes when it comes, and it lands on whoever is on shift that morning.

When you're responsible for several sites, the real cost of waiting isn't hard to name. It's the scramble the week before a visit you heard was coming, with records spread across three systems and two filing cabinets and a site lead who's never pulled the 300 log on a deadline. Or it's a day and a half of travel to stand in one building while four others go unwalked.

The records part has a clock on it. Under 29 CFR 1904.40, when an authorized government representative asks for your injury and illness records, you have four business hours to hand over copies. A practice OSHA inspection is the first time a lot of site leads find out whether they can do that.

A dry-run OSHA inspection flips the order of things. You find the gaps first, while there's still time to close them. If you've read our take on why proactive safety beats reactive, this is that idea with a date on the calendar.

Your Mock OSHA Inspection Checklist (the Audit Prep Checklist for Each Site)

This audit preparation checklist follows the parts of a real visit. Print one per site, and have whoever runs the mock complete it the same way every time. If you're working through a bigger push, pair it with our audit season prep checklist.

Documents and Postings

☐ OSHA 300 log, 300A annual summary, and 301 incident reports are on hand. OSHA requires you to keep them for five years after the year they cover.

☐ The site lead can pull those records in under four business hours. Time it.

☐ The 300A summary was certified by a company executive and posted from February 1 through April 30, as 1904.32 requires.

☐ The OSHA Job Safety and Health poster is up where workers can easily see it.

☐ Written programs that apply to the site are current and findable, such as hazard communication, lockout/tagout procedures, and respiratory protection.

☐ There's a Safety Data Sheet for every chemical actually on the shelves.

☐ Corrective actions from the last audit are listed with an owner, a due date, and a status.

The Walkthrough

☐ Start at the front door and walk the route an inspector would likely take.

☐ Check the hazards that show up most on OSHA's top 10 list that apply to your work (more on that below).

☐ Look at exits, housekeeping, guarding, labeled containers, and lockout points on the equipment people use every day.

☐ Photograph each finding and note its exact location.

☐ Mark anything the crew can fix on the spot. OSHA's fact sheet notes that prompt correction during a walkaround is a sign of good faith.

Employee Interviews

☐ Talk privately with a few workers across roles and shifts. Real inspectors consult privately with a reasonable number of employees, so practice it.

☐ Ask open questions. What's the most dangerous part of your job? Where are the Safety Data Sheets? Who do you tell about a near miss? Show me how you lock out this machine.

☐ Listen for specific answers. "I'd ask my supervisor" is honest, but it tells you training didn't stick.

☐ Know who the employee representative is, if the site has one, since they have the right to walk with the inspector.

PPE

☐ A written, certified PPE hazard assessment exists for the site, as 1910.132(d) requires in general industry.

☐ The PPE people are wearing is what the assessment calls for.

☐ Damaged or worn-out gear is pulled from use and replaced.

☐ Eye and face protection, hearing protection, and respirators are where the work needs them, not locked in a cabinet.

Training Records

☐ Training records exist for forklift operators, fall protection, lockout/tagout, and hazard communication.

☐ The names on the records are the people doing the work today, including temps and contractors.

☐ Expiring certifications are flagged with a date.

☐ Records are stored in one place, not split between paper and three inboxes.

How to Run It at Sites You Can't Reach

You don't have to be in the building to run a good practice OSHA inspection. A live video call works well when the site lead carries the phone and you direct the walk. Ask for photos as backup, because a still shot of a label or a guard is easier to read later than a shaky video frame.

Give the site lead this script before the call, so nobody's guessing:

1. "Start at the front entrance and show me where a visitor would check in."
2. "Show me the OSHA poster and this year's 300A summary."
3. "Pull the 300 log for this year and last year. I'll keep time."
4. "Walk me to the area with the most hazardous work, and point the camera at the guarding and the lockout points."
5. "Open the Safety Data Sheet for the closest chemical container."
6. "Hand the phone to one operator and step out of earshot for five minutes."
7. "Walk back to the office, and I'll read you what I found."

Video has limits. You can't smell a solvent or hear a compressor over a phone speaker, so treat remote mocks as a strong first pass. For a fuller multi-site safety audit rhythm, our guide on what to include in a quarterly multi-site safety audit lays out a standard framework you can reuse.

Audit vs. Inspection: What You're Actually Simulating

People use the two words like they mean the same thing, but they don't. A safety audit looks at your programs and systems against set criteria. A safety inspection walks the floor and looks for hazards and unsafe work. Our breakdown of 3 types of safety audits and how they differ from safety inspections covers the safety audit vs safety inspection question in more detail.

A mock OSHA audit rehearses OSHA's process. According to OSHA's fact sheet, the officer presents credentials, holds an opening conference, walks the covered parts of the workplace, reviews injury and illness records and the poster, talks privately with employees, and wraps up with a closing conference. The procedures inspectors follow are spelled out in OSHA's Field Operations Manual. For the rest of the picture, like picking a spokesperson and building a toolkit, see our full guide on how to prepare for an OSHA audit.

What Usually Fails First

In our experience, the work itself usually holds up, and the first thing to slip is the paperwork. Records kept partly on paper and partly in software turn into duplicate versions nobody trusts. That's one of the common mistakes in safety audits worth fixing first. Training that happened but never got written down is a close second.

On the floor, OSHA's top 10 most frequently cited standards are a good map of where to look. The preliminary list for fiscal year 2026 (October 1, 2025, to August 31, 2026) starts with fall protection, hazard communication, and lockout/tagout. It also includes scaffolding, ladders, respiratory protection, powered industrial trucks, fall protection training, eye and face protection, and machine guarding. OSHA publishes the list so employers can find and fix those hazards before an inspector shows up, so use it as your walkthrough priority list.

Construction sites have their own pattern, with fall protection and scaffolding near the top. If you run job sites, read the top 5 reasons construction sites fail their first safety audit before your next mock.

How to Score the Findings and Fix the Gaps

Keep the scoring simple enough that a site lead can use it without a training session. Sort every finding into one of three buckets:

• Fix today. Anything that could seriously hurt someone. Stop the work or guard the hazard before the call ends.
• Fix this month. Missing records, an outdated program, a training gap. Each one gets a named owner and a due date.
• Fix the system. The finding that shows up at three sites in a row. That's a process problem, and it belongs on your list, not the site lead's.

When you plan the fixes, use the NIOSH hierarchy of controls. Elimination, substitution, and engineering controls work better than leaning on PPE and signs, because they don't depend on someone getting it right every shift.

Then close the loop. Ask for a photo of each fix and a date it was done, and walk it again on the next mock. Corrective actions that never close are how the same finding shows up two years running, so the follow-up matters as much as the walk.

When to Bring In an Outside Professional

Sometimes the best person to run the mock isn't you. Somebody who's never walked that floor will catch things the site team has stepped around for months, and your site lead gets a real rehearsal with a stranger asking the questions. It also makes sense when a site is too far to reach this quarter or you need every location judged on the same standard.
