An OSHA inspection follows four phases: an opening conference where the compliance officer presents credentials and explains scope, a walkaround of your workplace, private interviews with employees, and a closing conference where findings are laid out. What happens during an OSHA inspection can take a few hours or stretch across weeks, depending on the size of your facility and why OSHA came. Any citation that follows must be issued within six months, and you have 15 working days to respond once it arrives. Serious violations now carry penalties up to $16,550 each, and willful or repeat violations reach $165,514.
Why OSHA Is at Your Door
OSHA does not inspect at random. The agency works from a priority list, and where your workplace sits on that list tells you a lot about what to expect.
- Imminent danger gets the fastest response. If OSHA learns workers face an immediate risk of death or serious physical harm, a compliance officer shows up without delay.
- Fatalities and catastrophes trigger inspections automatically. Employers must report a workplace fatality within eight hours and any hospitalization, amputation, or loss of an eye within 24 hours.
- Complaints and referrals from current or former employees, unions, or other agencies. OSHA evaluates severity and decides whether to inspect on-site or handle it by phone and letter.
- Programmed inspections are planned in advance using industry injury data, targeting high-hazard industries like construction, manufacturing, and warehousing.
The reason for the visit shapes the scope. A complaint about one machine may produce a focused inspection of that area, while a programmed inspection can cover the entire facility.
The Opening Conference
The inspection begins when a Compliance Safety and Health Officer arrives and presents official credentials. Federal regulations require the officer to show proper identification at the start of any inspection activity.1Occupational Safety and Health Administration. OSHA Credential Cards Program Ask to see them before letting anyone past the front door. If something looks off, call your local OSHA area office to verify.
The officer will explain why your workplace was selected, what the inspection will cover, and how it will proceed. Pay attention to whether the scope is limited to a specific complaint or covers the whole facility. That distinction affects how much of your operation gets scrutinized.
You Can Require a Warrant
You are not legally required to let OSHA in without a warrant. Under 29 CFR 1903.4, if you refuse entry the compliance officer must stop, report the refusal to the Area Director, and consult with OSHA’s Regional Solicitor to obtain one.2Occupational Safety and Health Administration. 29 CFR 1903.4 – Objection to Inspection The warrant process usually takes a day or two, so this buys limited time rather than an escape. You cannot destroy documents or alter conditions during that window. Some employers use the delay to get legal counsel on-site. Others see it as antagonizing the agency for little practical benefit. The right exists, but exercising it is a judgment call.
Who Walks Along
Both an employer representative and an authorized employee representative have the right to accompany the compliance officer. Each side gets one, and the officer resolves any disputes over who qualifies.3eCFR. 29 CFR 1903.8 – Representatives of Employers and Employees The employee representative can be a co-worker, a union steward, or a third party if the officer determines their expertise is reasonably necessary. Having your own representative present lets you see what the officer sees, take your own notes, and provide context in real time, rather than hearing about findings for the first time at the closing conference.
The Walkaround
The walkaround is the core of the inspection. The compliance officer moves through the workplace observing conditions, taking photographs or video, and using instruments to measure air contaminants and noise exposure. Potential hazards get documented as the officer sees them. Your representative earns their keep here by providing operational context and noting exactly which conditions drew attention.
Expect a document review as well. For most employers with more than ten employees, that means OSHA injury and illness records: the Form 300 log, the Form 300A annual summary, and the Form 301 incident reports.4Occupational Safety and Health Administration. 29 CFR 1904.32 – Annual Summary These need to be current and accessible. Missing or incomplete records are themselves a citable violation, so an officer who finds recordkeeping gaps has already found a problem before looking at a single machine guard.
Employee Interviews
During or after the walkaround, the compliance officer will talk to employees. These interviews happen privately, without management present, and their contents are confidential. The officer is trying to understand daily conditions from the perspective of the people actually exposed to hazards, and employees tend to be more candid when their supervisor is not standing three feet away.
Employees have real protections. They can refuse to participate, end the conversation at any time, decline to be recorded, and refuse to sign any written statement the officer prepares.
Retaliation Is Illegal
Section 11(c) of the OSH Act makes it illegal for an employer to fire, demote, transfer, or otherwise punish any employee for participating in an OSHA inspection, filing a safety complaint, or reporting a hazard.5Whistleblowers.gov. Occupational Safety and Health Act (OSH Act), Section 11(c) An employee who believes they were retaliated against can file a complaint with OSHA within 30 days. If OSHA finds merit, it attempts to negotiate a settlement; if that fails, the case is referred to the Department of Labor’s Office of the Solicitor. Remedies include reinstatement, back pay, and compensatory damages. Employers who retaliate create a much bigger problem for themselves than whatever the original inspection found.
The Closing Conference
After the walkaround and interviews, the compliance officer sits down with the employer and employee representatives. The officer walks through apparent violations, explains the basis for each, and outlines what comes next. This is a discussion, not a sentencing hearing. You can ask questions, provide additional context, and point out anything you believe was misunderstood.
The officer will also explain your rights going forward: how citations work, how penalties are calculated, the response timeline, and the option to request an informal conference with the Area Director. Take notes. The specifics discussed here become the foundation for any citations that follow.
Citations and What They Cost
OSHA classifies citations by severity, and the category drives the penalty:
- Serious: A hazard that could cause death or serious physical harm, where the employer knew or should have known.
- Other-than-serious: A violation related to workplace safety but unlikely to cause death or serious injury. Penalties are lower, sometimes zero for first-time offenders.
- Willful: The employer intentionally violated a standard or showed plain indifference to employee safety. Highest penalties, and criminal referral is possible if a worker dies.
- Repeat: The employer was previously cited for the same or a substantially similar condition within the past five years. Penalized at the same level as willful.
- Failure to abate: The employer did not fix a previously cited hazard by the deadline. Penalties accrue daily.
OSHA adjusts maximum penalties every January for inflation. Effective January 15, 2025, the caps are:
- Serious or other-than-serious: up to $16,550 per violation
- Willful or repeat: up to $165,514 per violation, with a minimum of $11,823 for willful
- Failure to abate: up to $16,550 per day the hazard remains uncorrected6Occupational Safety and Health Administration. 2025 Annual Adjustments to OSHA Civil Penalties
The maximum is not automatic. Small businesses with 25 or fewer employees qualify for up to a 70% reduction. Employers who take immediate corrective action can receive a 15% good-faith reduction. And with no history of serious, willful, repeat, or failure-to-abate violations in the past five years, you qualify for a 20% history reduction.7Occupational Safety and Health Administration. US Department of Labor Updates Penalty Guidelines to Support Small Businesses and Eliminate Workplace Hazards A small employer with a clean record and a cooperative attitude rarely pays anywhere near the maximum.
The 15-Day Clock and Fixing the Problem
OSHA has six months from the date of the violation to issue a citation.8Occupational Safety and Health Administration. OSH Act Section 9 – Citations Most arrive within a few weeks to a couple of months after the closing conference. When the citation shows up, you must post a copy at or near the location of the violation so affected employees can see it. The posting stays up for at least three working days or until the hazard is fully corrected, whichever is longer.9Occupational Safety and Health Administration. Citation and Notification of Penalty
You have 15 working days from receiving the citation to respond. Within that window you can request an informal conference with the Area Director to discuss adjustments to the citation, the penalty, or the abatement deadline. You can also file a formal notice of contest challenging any or all of it. Do neither, and the citation becomes a final order of the Occupational Safety and Health Review Commission that no court or agency can review.10Occupational Safety and Health Administration. 29 CFR 2200.33 – Notices of Contest That 15-day clock is the single most important deadline in the entire process. Miss it and you lose every option.
Every citation also carries an abatement date by which you must correct the hazard. Within ten calendar days of that date, send an abatement certification to the OSHA Area Office that issued the citation, confirming the fix is complete. For violations with abatement periods longer than 90 days, you must submit an abatement plan within 25 calendar days of receiving the citation, plus progress reports at intervals specified on the citation.11Occupational Safety and Health Administration. Small Entity Compliance Guide for OSHA’s Abatement Verification Regulation Employees have the right to examine and copy any abatement documents you send OSHA.
Failing to correct a cited hazard by the abatement date triggers failure-to-abate penalties that compound daily. If the original citation felt expensive, the daily accrual for leaving the problem in place will feel considerably worse.
