How to report OSHA violations: a step-by-step guide

Last updated 2026-07-09

Who can report an OSHA violation?

Anyone can file an OSHA complaint. You don't have to be the one in danger. Current employees, former employees, union representatives, family members of workers, and members of the public can all submit a complaint ^[1].

Worker complaints carry the most weight. When a current or former employee (or their authorized representative, like a union) files a formal signed complaint, OSHA is required under Section 8(f)(1) of the Occupational Safety and Health Act of 1970 to conduct an inspection if the complaint alleges a violation that poses imminent danger or that has already caused, or is likely to cause, serious physical harm ^[2]. Anonymous or third-party complaints usually get a letter to the employer asking for a written response, not an on-site visit.

So if you're a worker and you sign the complaint, you get the stronger enforcement response. Worth knowing before you decide how to file.

What counts as an OSHA violation worth reporting?

OSHA covers most private-sector employers in the U.S., plus federal agencies. If a hazard violates an OSHA standard, or if a serious recognized hazard exists even without a specific standard (the General Duty Clause, Section 5(a)(1) of the OSH Act), it's reportable ^[2].

Common complaints involve missing machine guarding, no fall protection, blocked emergency exits, no personal protective equipment, missing lockout/tagout procedures (see lockout tagout), improper chemical labeling (see hazard communication), and no written safety programs where required.

Not sure whether a hazard rises to the level of a violation? File anyway. Compliance officers evaluate complaints, and they'll tell you if the hazard falls outside their jurisdiction. You won't get in trouble for reporting something that turns out not to be a violation.

OSHA can't act on general working-condition gripes with no safety or health hazard, wage disputes, or issues handled by other agencies. Those go elsewhere, and OSHA's website will point you there.

What are the different ways to file an OSHA complaint?

There are five ways to report a violation, each with its own use case.

Online: The fastest method. Go to osha.gov and use the online complaint form. You can submit anonymously or with your name. OSHA recommends this for non-imminent-danger situations where a detailed written record matters ^[1].

Phone: Call 1-800-321-OSHA (1-800-321-6742), or call your nearest OSHA area office directly. If the hazard is imminent, meaning someone could be seriously hurt or killed very soon, call first. Don't wait to fill out a form.

Fax or mail: Download Form OSHA-7 from osha.gov, fill it out, and send it to your local OSHA area office. This is the original method and still works fine. Find your area office using the office locator on osha.gov.

In person: Walk into any OSHA area office. Useful if you have physical documents, photos, or equipment samples to hand over alongside your complaint.

Through a union: If a union represents you, it can file on your behalf as your authorized representative. The complaint carries the same weight as a direct worker complaint.

Method	Best for	Identity protected if you ask?	Triggers on-site inspection?
Online	Most situations	Yes	Yes, if signed
Phone	Imminent danger	Yes	Yes, if you provide name
Fax/Mail (Form OSHA-7)	Documentation-heavy complaints	Yes	Yes, if signed
In person	Complex situations	Yes	Yes, if signed
Anonymous (any method)	When safety is paramount	N/A (no name given)	Usually no, letter instead

How do you file the OSHA complaint online, step by step?

Here's exactly what to do.

1. Go to osha.gov, click "Workers" in the top navigation, then "File a Complaint" ^[1].

2. Choose whether federal OSHA or a state plan covers your workplace. OSHA's site has a map showing which states run their own programs. If your state has a state plan (California, Michigan, Washington, and 25 others), you'll get redirected to that state's complaint portal ^[3].

3. Fill in the employer's name, address, and a description of the hazard. Be specific. "No fall protection" is weaker than "Workers are framing the second-floor deck at 123 Main St without guardrails, safety nets, or personal fall arrest systems, in violation of 29 CFR 1926.502." The more detail you give, the easier the investigation.

4. Add the approximate number of workers exposed and how long the condition has existed.

5. Note whether you've reported the hazard to your employer and what response you got. If you asked management to fix it and they refused, say so explicitly.

6. Indicate whether you want OSHA to keep your identity confidential. Check that box if you're worried about retaliation.

7. Sign the form electronically with your name. Unsigned online complaints drop into a lower-priority queue and usually get a letter to the employer rather than an inspection ^[1].

8. Submit and save your complaint number. OSHA will contact you, usually by phone, to discuss next steps.

What happens after you submit an OSHA complaint?

OSHA screens every complaint that comes in. A compliance officer evaluates the alleged hazard and decides whether it warrants an on-site inspection, a phone/fax investigation (where OSHA contacts the employer for a written response), or a referral to another agency.

Imminent danger gets the fastest response. OSHA's policy is to respond within 24 hours for imminent danger complaints ^[1]. For serious complaints, the target is one to five business days in most area offices, though actual response times swing with office workload. Other-than-serious complaints can take weeks.

If OSHA inspects, the compliance officer arrives unannounced. Employers don't get advance notice for complaint-based inspections. The officer walks the site, interviews workers privately, and reviews records. Find violations, and OSHA issues citations with proposed penalties.

Federal OSHA conducted about 34,000 inspections in fiscal year 2023 ^[4]. A signed complaint from a worker is one of the strongest triggers for an inspection there is.

You can check your complaint status by contacting your local OSHA area office. There's no public online tracking dashboard, so you'll need to call or email.

Can you report a violation anonymously, and will OSHA protect your identity?

Yes on both. You can report without giving your name at all, and your complaint still gets processed. The tradeoff is enforcement strength: anonymous complaints almost always get a letter to the employer rather than an inspection, because OSHA can't follow up with you for details or witness confirmation.

Give your name but ask OSHA to keep it confidential, and OSHA won't disclose your identity to the employer. This protection comes from Section 8(f)(2) of the OSH Act ^[2]. Compliance officers are trained to run inspections without revealing who filed.

The stronger protection is Section 11(c) of the OSH Act, which makes it illegal for employers to retaliate against workers for filing complaints, taking part in OSHA inspections, or exercising any right under the Act ^[2]. If an employer fires, demotes, cuts hours, or otherwise retaliates, the worker can file an 11(c) retaliation complaint with OSHA. The deadline is 30 days from the adverse action ^[5].

Retaliation protection is real but not instant. OSHA investigates, and if it finds merit, it can order reinstatement, back pay, and other remedies. The process takes time. If your situation is urgent, talk to an employment attorney in parallel.

What if your state has its own OSHA plan?

Twenty-six states and two territories run their own occupational safety and health programs, called State Plans. These cover most private-sector employers and sometimes state and local government workers ^[3]. Federal OSHA doesn't cover those workers directly.

State Plan states include California (Cal/OSHA), Michigan (MIOSHA), Washington (L&I), and most of the western U.S., among others. Work in a State Plan state, and you file your complaint with the state agency, not federal OSHA.

The process is similar. State Plans are required by federal law to be "at least as effective" as federal OSHA ^[3]. Some states go stricter on certain hazards. California's heat illness prevention standard, for example, reaches well beyond anything in federal OSHA.

The osha.gov/stateplans page has a full list with links to each state agency. When you use the online complaint form on osha.gov, the system redirects you to the right state portal if your state has its own plan.

Not sure which program covers your workplace? Check the state plans page or call 1-800-321-OSHA and ask.

How do you report an imminent danger situation specifically?

An imminent danger is any condition where there's reasonable certainty that death or serious physical harm could happen immediately, or before the hazard can be eliminated through normal enforcement procedures ^[2].

Call first. Use 1-800-321-OSHA or your local area office. OSHA's policy is to respond to imminent danger complaints within 24 hours ^[1]. When you call, say the words "imminent danger" out loud, describe what you saw, give the employer's address, and stay available for follow-up questions.

If OSHA can't respond fast enough and workers are in immediate danger, workers have the right to refuse the unsafe work. The legal standard for work refusal, set in the Supreme Court case Whirlpool Corp. v. Marshall (1980), requires a reasonable belief that the risk is imminent and that normal channels haven't fixed it ^[6].

Don't wait for paperwork in a true emergency. Call OSHA. And if someone's already been hurt, employers must report hospitalizations and fatalities to OSHA directly: all work-related fatalities within 8 hours, and in-patient hospitalizations, amputations, or loss of an eye within 24 hours ^[7]. If the employer isn't reporting, OSHA wants to know that too.

What information should your complaint include to get results?

The more specific your complaint, the more likely it results in an inspection and a finding. Here's what to include.

Employer information: exact legal name, physical address of the site where the hazard exists (more than corporate HQ), and if you know it, the NAICS industry code or a plain description of what the business does.

Hazard description: describe the condition in plain language. Name the equipment, the location on the site, and how many workers are exposed. Know the standard being violated? Cite it. For example: "No machine guarding on the table saw in the woodshop, violating 29 CFR 1910.212." Don't know the standard number? Fine. Compliance officers know the standards cold.

History: how long has this condition existed? Has anyone been hurt? Have workers or supervisors complained internally and been ignored?

Evidence: photos and videos are powerful. You can attach files to the online complaint form. Took photos on your phone? Include them. OSHA can't subpoena your photos, but submitting them voluntarily speeds things up.

Your contact info: if you want a real inspection rather than a letter, provide your name and mark it confidential. Make sure OSHA can reach you for follow-up.

If your business needs to get its own safety documentation in order before a complaint triggers an inspection, a tool like SafetyFolio can generate a written safety program in about 15 minutes, which at least shows good faith on the employer's side.

What OSHA penalties can result from a reported violation?

When an inspection finds violations, OSHA issues citations and proposed penalties. The amounts get adjusted for inflation every year under the Federal Civil Penalties Inflation Adjustment Act Improvements Act of 2015 ^[8].

As of 2024, the maximum penalties are:

Violation type	Maximum penalty per violation
Other-than-serious	$16,131
Serious	$16,131
Willful or repeated	$161,323
Failure to abate	$16,131 per day

Actual penalties usually come in lower. OSHA applies adjustment factors for employer size (small businesses get up to a 70% reduction), good faith (demonstrated safety efforts), history, and the gravity of the violation. An average serious violation in recent years settles somewhere in the $4,000 to $7,000 range, though this swings widely by case.

Willful violations that result in a fatality can also trigger criminal referral to the Department of Justice. That's rare but real.

From a worker's seat, the penalty structure tells you how OSHA sets priorities. Imminent danger and willful violations get the most attention. Other-than-serious violations with no injured workers rank lower, though they still get addressed.

Understanding what happens after an inspection also helps employers prepare. If your workplace is thin on written programs, incident reporting processes (see incident report), or training records (see osha training), those gaps show up fast during an inspection.

Can employers report OSHA violations by competitors or other businesses?

Yes. Nothing requires the person filing to be a worker at the site in question. A business owner, contractor, or member of the public can file about any workplace.

Employer-filed complaints against competitors do happen. OSHA processes them, but the priority and enforcement response differ. An anonymous complaint from someone who isn't a worker at the site is far less likely to trigger an on-site inspection than a signed complaint from an employee.

An employer who spots a hazard at a client's site, a subcontractor's operation, or a neighboring business can and should report it. Multi-employer worksite rules (OSHA Instruction CPL 02-00-124) make clear that controlling employers can be cited for hazards affecting workers other than their own employees ^[9]. So reporting a hazard at a shared site isn't only about the other company. It might affect your legal exposure too.

What if nothing happens after you file your complaint?

It happens. OSHA area offices are understaffed relative to demand. In fiscal year 2023, federal OSHA had roughly 1,000 inspectors to cover about 10 million workplaces ^[4]. The math doesn't work.

Filed a complaint and heard nothing in a week or two on a serious (non-imminent-danger) issue? Call your local area office and ask for a status update. Reference your complaint number. Be politely persistent.

If OSHA closes your complaint without an inspection and you believe the hazard is serious, request reconsideration in writing to the area director. Explain why the hazard warrants an on-site visit rather than a letter to the employer.

You can also contact your Congressional representative's office. Constituent service offices routinely reach out to federal agencies for constituents, and OSHA area offices respond to Congressional inquiries.

State legislatures and state labor departments are another avenue in a State Plan state. Some states run ombudsman programs specifically for workplace safety complaints.

And if you've been retaliated against for filing, that changes the calculus. File the 11(c) complaint immediately. OSHA handles retaliation cases separately from the underlying safety complaint, and the 30-day deadline is hard ^[5].

Where can employers find their written safety obligations before a complaint triggers an inspection?

If you're an employer reading this because you've received notice of a complaint, or because you want to get ahead of one, the first move is to audit your written safety programs against OSHA's requirements.

OSHA requires written programs for many specific standards: Hazard Communication (29 CFR 1910.1200), Lockout/Tagout (29 CFR 1910.147), Respiratory Protection (29 CFR 1910.134), Emergency Action Plans (29 CFR 1910.38), and others depending on your industry ^[11]. A compliance officer asks to see these on day one of an inspection.

SafetyFolio's safety program generator can get those written programs drafted in about 15 minutes. That won't fix a physical hazard, but it does show good faith on the documentation side.

For deeper preparation, OSHA's On-Site Consultation Program offers free and confidential safety reviews for small businesses. Consultants identify hazards and help you fix them, and visits under this program don't result in citations or penalties ^[10]. It's funded by OSHA but run by state agencies, and participation stays genuinely separate from enforcement.

Knowing your obligations under the OSHA standards that apply to your industry is the starting point. The osha overview and what does osha stand for articles on this site cover the foundational framework.

Frequently asked questions

How long does OSHA take to respond to a complaint?

For imminent danger complaints, OSHA's policy is to respond within 24 hours. For serious complaints, most area offices aim for one to five business days, though actual timelines depend on office workload. Non-serious complaints can take weeks. Calling your local OSHA area office after a week with no contact is reasonable if you filed a serious complaint.

Can I report an OSHA violation without giving my name?

Yes. Anonymous complaints are accepted through every filing method. The tradeoff is enforcement: anonymous complaints usually get a letter to the employer asking for a written response, not an on-site inspection. If you give your name but ask OSHA to keep it confidential, OSHA won't disclose your identity to the employer, and you're more likely to trigger an actual inspection.

Can my employer fire me for reporting an OSHA violation?

No. Section 11(c) of the OSH Act prohibits retaliation against workers who file complaints, take part in inspections, or exercise any right under the Act. If your employer retaliates, you have 30 days from the adverse action to file a retaliation complaint with OSHA. Remedies can include reinstatement and back pay. The 30-day deadline is strict, so act quickly.

What is the phone number to report an OSHA violation?

Call 1-800-321-OSHA, which is 1-800-321-6742. This line is available 24 hours a day for imminent danger situations. You can also find the direct phone number for your nearest OSHA area office at osha.gov, which can sometimes reach a compliance officer faster for follow-up questions.

Can I report an OSHA violation online?

Yes. Go to osha.gov, click Workers, then File a Complaint. The online form lets you describe the hazard in detail, attach photos, and indicate whether you want confidentiality. If your state has its own OSHA plan, the site redirects you to the correct state agency portal. Signed online complaints get the same priority as mailed or faxed signed complaints.

What happens to the employer after an OSHA complaint is filed?

OSHA either sends a letter asking the employer for a written explanation of the hazard and how they're fixing it, or it schedules an unannounced inspection. If an inspector finds violations, OSHA issues citations with proposed penalties. Employers have 15 working days to contest citations. Penalties are negotiated and can drop for small employer size, good faith effort, and history.

Does OSHA cover all workplaces in the United States?

Federal OSHA covers most private-sector employers and federal agencies. It does not cover self-employed workers with no employees, family farms where only immediate family members work, or workplaces regulated by other federal agencies under different safety statutes (like mines under MSHA). Twenty-six states and two territories have OSHA-approved state plans that cover state and local government workers too.

What is an imminent danger under OSHA, and how do you report it?

An imminent danger is any condition where there's reasonable certainty that death or serious physical harm could happen immediately or before the hazard can be fixed through normal enforcement. Call 1-800-321-OSHA or your local area office and say "imminent danger" out loud. OSHA's policy is to respond within 24 hours. Don't wait to fill out an online form for a genuine imminent danger situation.

How do I report a safety violation in a state with its own OSHA program?

File with the state agency, not federal OSHA. States with their own plans include California (Cal/OSHA), Michigan (MIOSHA), Washington (L&I), and 23 others. The osha.gov/stateplans page lists all state programs with contact information and complaint portals. The online complaint form on osha.gov redirects you automatically if your state has a plan.

Can a business owner report OSHA violations at another company?

Yes, anyone can file a complaint, including business owners, contractors, or members of the public. Third-party and anonymous complaints get processed but usually receive a letter to the employer rather than an inspection. A signed complaint from a worker at the site triggers the stronger enforcement response. Reporting real hazards at other companies' sites is always appropriate.

What form do I use to report an OSHA violation by mail?

Use Form OSHA-7, the formal complaint form. Download it from osha.gov, complete it, sign it, and mail or fax it to your nearest OSHA area office. A signed mailed complaint gets the same enforcement priority as a signed online submission. Find your local area office address and fax number using the office locator on osha.gov.

How much can OSHA fine an employer for a violation?

As of 2024, OSHA's maximum penalty for a serious or other-than-serious violation is $16,131 per violation. Willful or repeated violations can reach $161,323 per violation. Failure to abate a cited hazard adds up to $16,131 per day. Penalties are adjusted annually for inflation and usually drop based on employer size, good faith, and the gravity of the hazard.

Can I report an OSHA violation if I no longer work at the company?

Yes. Former employees can file OSHA complaints. The enforcement response is typically stronger for current workers since OSHA can interview them during an inspection, but former employees can still describe hazards they witnessed, and those complaints get processed. Retaliation protection for former employees who file after leaving is a more complex legal area; consult an employment attorney if that's a concern.

What should I document before filing an OSHA complaint?

Document the specific hazard location, the equipment or condition involved, how many workers are exposed, and how long the condition has existed. Photos and short videos are the most useful evidence. Note whether you or coworkers raised the issue with management and what response you got. Written records of prior complaints to supervisors strengthen your complaint and help OSHA build a case faster.
