OSHA Contact Number: Complete Directory of Phone Numbers, Regional Offices, and How to Reach OSHA for Questions, Complaints, and Emergencies
Find the OSHA contact number for complaints, emergencies, and questions. Complete directory of regional offices, hotlines, and online reporting tools.

Finding the right OSHA contact number can feel surprisingly difficult when you actually need it. Whether you are reporting a workplace fatality, asking about a regulation, filing a whistleblower complaint, or trying to verify a crane operator certification, the Occupational Safety and Health Administration uses several different phone lines depending on the urgency, geography, and nature of your inquiry. The main national OSHA contact number is 1-800-321-OSHA (1-800-321-6742), which routes callers to the appropriate regional office based on the area code or location of the workplace involved.
This guide walks you through every official phone line, online portal, and regional contact OSHA maintains, and explains exactly which one to use for your situation. We also cover what information to have ready before you call, what to expect after you submit a report, and how OSHA prioritizes complaints. Construction workers, crane operators, supervisors, safety managers, and employees in general industry all interact with OSHA differently, and using the wrong channel can delay a response by weeks.
The 1-800-321-6742 hotline operates 24 hours a day, seven days a week, for fatalities and imminent danger situations. For non-emergency questions, the same number is staffed Monday through Friday during normal business hours. Federal OSHA covers 29 states, while 22 states and territories operate their own state-plan OSHA programs with separate phone numbers and complaint procedures. Knowing whether your state is federal or state-plan affects who you call and which regulations apply to your workplace.
OSHA also maintains separate contact channels for whistleblower complaints under more than 25 federal statutes, training course questions related to the OSHA Outreach Training Program, and technical assistance through On-Site Consultation Programs designed for small businesses. Each channel has its own response time, confidentiality protections, and follow-up process. Confusing them is one of the most common mistakes workers make when first trying to reach the agency, and it often leads to frustration that could have been avoided with a five-minute orientation.
Throughout this guide we will reference real phone numbers, mailing addresses, and online forms current as of 2026. We will also explain the difference between filing a complaint that triggers an inspection and simply asking a regulatory question that does not. If you are studying for a crane operator certification or other OSHA credential, you may also benefit from our OSHA (OSHA Certified Crane Operator) Test Guide, which covers many of the standards OSHA enforces in the construction industry.
By the end of this article you will know exactly which OSHA contact number to dial for your situation, what your rights are when you call, and how to follow up if you do not receive a response. We have also included a downloadable checklist of information to gather before you pick up the phone, because the more organized your call is, the faster OSHA can route you to the right inspector, compliance officer, or technical specialist who can actually help.
OSHA Contact System by the Numbers

Primary OSHA Phone Numbers You Should Know
1-800-321-OSHA (1-800-321-6742) is the main number for fatalities, imminent danger reports, general questions, and complaint filing. Operates 24/7 for emergencies. Routes you to the closest area office based on your location.
1-877-889-5627 connects deaf or hard-of-hearing workers to OSHA directly. Available during regular business hours and supports all the same services as the main hotline, including complaint filing and technical questions.
Call the main 1-800-321-6742 number and ask for the Whistleblower Protection Program, or contact your regional whistleblower coordinator directly. Strict deadlines apply, often 30 days but up to 180 for some statutes.
202-693-1999 reaches OSHA's national office in Washington DC for policy questions, FOIA requests, and media inquiries. Not for filing complaints â use the regional or area office for inspection-related calls instead.
Free, confidential safety consultations for small businesses are arranged through state-specific phone numbers listed on osha.gov/consultation. These do not trigger inspections or citations, making them ideal for proactive employers.
Federal OSHA divides the United States into 10 regions, each headed by a Regional Administrator who oversees several Area Offices. When you dial 1-800-321-6742, the call routes automatically to the regional office covering your zip code, but you can also call the regional office directly if you prefer. Knowing your region helps when you need to follow up on an existing complaint or speak with a specific compliance officer who has been assigned to your case. Each region also handles its own whistleblower complaints through a dedicated regional coordinator.
Region 1 covers Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont, with headquarters in Boston at 617-565-9860. Region 2 includes New York, New Jersey, Puerto Rico, and the Virgin Islands, headquartered in New York City at 212-337-2378. Region 3 covers Delaware, the District of Columbia, Maryland, Pennsylvania, Virginia, and West Virginia, with offices in Philadelphia reachable at 215-861-4900. Workers in these areas can also use the main hotline, but direct dial often connects you to a person faster during busy periods.
Region 4 covers Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee from Atlanta at 678-237-0400, though several of these states are state-plan and route to their own agencies. Region 5 includes Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin, headquartered in Chicago at 312-353-2220. Region 6 covers Arkansas, Louisiana, New Mexico, Oklahoma, and Texas from Dallas at 972-850-4145. Region 7 covers Iowa, Kansas, Missouri, and Nebraska from Kansas City at 816-283-8745.
Region 8 covers Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming, with headquarters in Denver at 720-264-6550. Region 9 includes Arizona, California, Hawaii, Nevada, American Samoa, Guam, and the Northern Mariana Islands, headquartered in San Francisco at 415-625-2547. Region 10 covers Alaska, Idaho, Oregon, and Washington from Seattle at 206-757-6700. State-plan states within these regions, such as California and Washington, generally direct complaints to their own state agencies rather than federal OSHA except in specific federal jurisdiction cases.
If you are not sure whether your state has its own OSHA plan, the easiest way to find out is to call 1-800-321-6742 and tell the operator your zip code. They will route you appropriately. State-plan states must adopt standards at least as effective as federal OSHA but often have additional requirements.
For example, California's Cal/OSHA enforces heat illness prevention rules that go beyond federal requirements, and Washington's L&I has its own permit-required confined space standards. If you need to research past inspections in your area, the OSHA Establishment Search: How to Use the Inspection Database walks through how to query OSHA's public database of citations and inspections.
Each Area Office, which sits beneath the Regional Office, is where actual inspections originate. There are roughly 85 federal Area Offices across the United States. Each one has a designated Area Director who supervises the Compliance Safety and Health Officers (CSHOs) who conduct workplace inspections. When you file a complaint by phone, fax, mail, or online, the case is assigned to the Area Office covering the workplace's physical location, not your home address. This matters if you work remotely or travel for jobsite assignments â always reference the actual job location when reporting.
For non-emergency technical questions about specific regulations, OSHA also operates a separate technical support line through the Directorate of Technical Support and Emergency Management. Many compliance officers and area office staff will redirect detailed regulatory interpretation questions to this line or to the Letters of Interpretation database on osha.gov. If you are studying for a certification exam and need clarification on a standard, the published Letters of Interpretation are often more useful than calling, because they document OSHA's official position with citations to the Code of Federal Regulations.
OSHA Contact Methods: Phone, Online, Fax, and Mail
Calling 1-800-321-6742 is the fastest way to reach OSHA for emergencies. The hotline is staffed 24 hours a day, seven days a week, including holidays, specifically for reporting work-related fatalities and imminent danger situations. Be ready to provide the employer name, exact workplace address, your name and contact information if you are willing to share, and a clear description of the hazard or incident. The operator may transfer you to a duty officer or take a written statement.
For non-emergency questions about standards, training requirements, or how to file a complaint, the same hotline operates Monday through Friday from 8 AM to 8 PM Eastern. Phone calls allow you to ask clarifying questions in real time, which is especially useful when describing complex situations like multi-employer worksites, crane operator certifications, or scaffold violations. If your call drops or you need a callback, ask the operator for a case number before hanging up so you can reference the conversation later.

- âA pen and paper to record the case number, intake officer name, and next steps
Employers must call OSHA within 8 hours of a workplace fatality
Under 29 CFR 1904.39, employers must report any work-related fatality to OSHA within 8 hours and any in-patient hospitalization, amputation, or loss of an eye within 24 hours. The only way to satisfy this requirement is by calling 1-800-321-6742, calling your nearest Area Office, or using OSHA's online reporting form. Email and fax do not count. Failure to report can result in citations of up to $16,131 per violation as of 2026.
Once you contact OSHA, the agency follows a defined intake and triage process that determines how quickly your concern is addressed. Reports of imminent danger, fatalities, and catastrophic incidents involving three or more hospitalizations receive the highest priority and typically trigger an on-site inspection within 24 hours. Complaints alleging serious hazards but not imminent danger are usually addressed within five working days through either a phone or fax investigation or, when warranted, an unannounced on-site visit. Non-formal complaints, which are unsigned or non-specific, often result in a letter to the employer requesting a written response.
If you file a formal complaint â meaning signed, in writing, and alleging a specific violation â OSHA is required to investigate. The Area Office assigns a Compliance Safety and Health Officer who reviews the complaint, contacts the employer if appropriate, and decides whether to conduct an inspection. You will receive periodic updates by mail or phone, and a final closing letter explaining the outcome. Inspectors cannot disclose the identity of complainants who requested confidentiality, even during the on-site walkaround or in citation paperwork shared with the employer.
Inspections themselves follow a structured sequence: an opening conference where the inspector explains the scope, a walkaround of the workplace with employer and employee representatives, employee interviews conducted privately, a review of injury logs and required programs, and a closing conference summarizing findings. If violations are observed, citations are issued by mail within six months of the inspection, and the employer must post each citation prominently in the workplace for three working days or until the violation is abated, whichever is longer. Penalties range from $0 for de minimis violations to over $161,323 per willful or repeated violation in 2026.
Employers have 15 working days from receiving a citation to contest it before the Occupational Safety and Health Review Commission. During that window, employers can also schedule an informal conference with the Area Director to discuss reducing penalties, extending abatement dates, or reclassifying violations. Workers who filed the original complaint have the right to be notified of these conferences and may participate, although the rules vary by region. If you want a meaningful voice in post-inspection negotiations, request employee representation status early in the process.
For training-related questions â such as whether your card is still valid, what your trainer was authorized to teach, or how to verify a course completion â OSHA generally directs callers to the OSHA Training Institute Education Centers rather than handling these calls at the area office level. Card verification and replacement requests must go through the original authorized trainer. If your card was lost and your trainer is unreachable, the article on How Long Is OSHA 10 Good For? Card Validity, Renewal Rules & Employer Requirements Explained covers the official replacement procedures step by step.
For whistleblower complaints, the process is entirely separate from the regulatory complaint track. Whistleblower investigators work under OSHA's Directorate of Whistleblower Protection Programs and investigate retaliation claims under the OSH Act and more than 25 other statutes including the Surface Transportation Assistance Act, the Sarbanes-Oxley Act, and various environmental laws. Time limits are strict â 30 days for OSH Act retaliation, 180 days for many other statutes, and as little as 30 days for some transportation laws. Missing the deadline almost always closes your case, so call the moment you suspect retaliation.
Throughout the process, you have the right to request copies of documents in your case file under the Freedom of Information Act. FOIA requests are submitted in writing to the regional FOIA officer and processed within 20 working days, though high-volume regions sometimes take longer. Personal identifying information of other complainants and witnesses is redacted. If you are denied records, you can appeal through the Department of Labor's Solicitor's Office. Knowing these procedural rights ahead of time helps you stay in control of your own case rather than waiting passively for updates that may never arrive without a follow-up call.

If you have been fired, demoted, or otherwise retaliated against for raising a safety concern, you generally have only 30 days under the OSH Act to file a whistleblower complaint with OSHA. Some related statutes give you 180 days, but many give you fewer. Do not wait â call 1-800-321-6742 immediately and ask for the Whistleblower Protection Program.
Worker rights when contacting OSHA are protected by Section 11(c) of the Occupational Safety and Health Act and reinforced by more than two dozen related federal statutes. These laws make it illegal for employers to fire, demote, transfer, deny benefits, intimidate, or otherwise retaliate against any employee who exercises their rights under the Act. Reporting a hazard, filing a complaint, requesting an inspection, testifying in an OSHA proceeding, or participating in a workplace safety committee are all protected activities, whether the underlying safety concern turns out to be a violation or not.
When you call the OSHA contact number to report a hazard, the intake officer will ask whether you want to remain anonymous, identify yourself but request confidentiality, or be identified publicly. Most workers should choose confidentiality â OSHA is legally required to honor that request, and inspectors are trained to walk through entire facilities without tipping off the employer about who triggered the inspection. Anonymous reports are accepted but receive lower priority and cannot be classified as formal complaints, which limits OSHA's obligation to investigate.
Many states and territories have their own whistleblower laws that supplement the federal protections, sometimes with longer filing deadlines or stronger remedies including punitive damages. California Labor Code Section 1102.5, New Jersey's CEPA, and similar statutes in New York, Illinois, and elsewhere often provide additional rights worth exploring with an employment attorney. State-plan OSHA agencies generally handle their own whistleblower complaints, while federal OSHA continues to handle complaints under the 20+ federal statutes regardless of which state you work in. Calling the federal OSHA contact number first is rarely a mistake â they will redirect you if needed.
If you are a construction worker, crane operator, scaffold erector, or worker in another high-hazard trade, you also have specific training rights under OSHA standards like 29 CFR 1926.21 (general construction training) and 29 CFR 1926.1427 (crane operator certification). Employers must provide training in a language and at a literacy level workers can understand.
If you have been put to work without proper training, that is itself a violation you can report. The 360 OSHA Training: Complete Guide to Online OSHA 10 & 30 Certification Courses guide explains which courses satisfy specific job requirements and how to verify a course is OSHA-authorized.
OSHA also encourages employees to participate in inspections directly. During an inspection, employees have the right to designate a representative to accompany the CSHO during the walkaround. In union workplaces, this representative is usually the union steward. In non-union workplaces, employees can designate any individual they reasonably believe will aid the inspection, including an attorney or industrial hygienist. The employer cannot block the designated representative without legitimate safety reasons. If you are blocked, report it immediately â that itself becomes part of the inspection record.
Confidentiality protections continue beyond the initial complaint. Citation paperwork shared with the employer does not list complainant names. Documents released under FOIA are redacted. Inspector field notes are sealed. Only in rare circumstances â typically when a complainant becomes a key witness in a criminal referral â is identity ever disclosed, and even then with significant legal process. If you ever feel your confidentiality has been compromised, report it to the Area Director and the regional whistleblower coordinator. This is itself a serious procedural violation that OSHA takes very seriously, both for compliance and for credibility reasons.
Finally, remember that contacting OSHA does not commit you to any particular outcome. You can ask questions without filing a complaint. You can file a complaint and later request that it be closed. You can report a hazard anonymously through the online portal without ever speaking to anyone.
The agency is designed to give workers multiple entry points so that fear of formality or retaliation does not stop unsafe conditions from being addressed. The most important thing is to make initial contact, document the date, and preserve your evidence â because written complaints filed within 30 days of an incident carry far more weight than verbal recollections months later.
Practical tips can save you significant time when you finally pick up the phone. First, call early in the day, ideally between 8 AM and 10 AM local time. Wait times tend to spike after lunch and on Monday mornings. If the main hotline has long hold times, try calling your regional office directly â the number is published on osha.gov/contactus and frequently has shorter queues. Have your information organized in a single document or notepad before dialing, so you do not waste call time looking for addresses, dates, or names while the operator waits.
Second, write down the operator's name and your case number within the first two minutes of the call. If the call disconnects, having that information lets you pick up exactly where you left off. Ask the operator to confirm spelling of your name, your callback number, and the workplace address. Mistranscribed addresses are one of the most common reasons complaints get routed to the wrong Area Office, which can add weeks to your timeline. Read everything back at the end of the call to catch errors before you hang up.
Third, follow up in writing. Even if you make your initial report by phone, send a follow-up email or letter to the same Area Office summarizing what you reported, the date and time of the call, the operator's name, and your case number. This creates a paper trail you can reference if the case stalls. Keep copies of everything in a single folder, labeled by date, and consider storing scans in the cloud so you can retrieve them from any device. Documentation is your strongest ally if anything escalates.
Fourth, do not exaggerate or speculate. OSHA investigators are skilled at separating documented hazards from rumor, and embellishing your report damages your credibility for any future contact. Describe what you have personally observed, photographed, or heard directly from coworkers. If a coworker has firsthand information, encourage them to file their own report â multiple complaints about the same hazard significantly increase the likelihood of an on-site inspection and signal that the issue is not isolated to one disgruntled worker.
Fifth, learn the specific standards that apply to your situation before you call. You do not need to be a regulatory expert, but knowing whether your concern falls under 29 CFR 1910 (general industry) or 29 CFR 1926 (construction) helps you communicate clearly. Crane-related concerns typically fall under Subpart CC of 1926. Fall protection in construction falls under Subpart M. Scaffolding under Subpart L. Citing the right standard tells the intake officer you have done your homework and signals that you are a credible reporter worth taking seriously.
Sixth, if you are an employer wondering about OSHA compliance rather than reporting a hazard, do not call the main complaint hotline. Instead, contact your state's On-Site Consultation Program, which provides free, confidential safety advice without triggering inspections or citations. These programs are listed at osha.gov/consultation and are particularly valuable for small businesses with fewer than 250 employees. Consultants will identify hazards, suggest corrections, and help you develop required written programs without any enforcement risk whatsoever.
Finally, if you are a trainer, course provider, or student trying to verify a credential or course authorization, route those calls to the OSHA Training Institute Education Center for your region rather than the main hotline. These centers handle Outreach Training Program questions, trainer authorizations, and curriculum approvals. The main hotline staff are not equipped to answer detailed training questions and will redirect you anyway.
Save yourself the call transfer by going straight to the right place â the Education Center directory is published on osha.gov/training. For deeper credential research, our OSHA 500 Course Online: Complete Guide to Trainer Certification walks through the process for becoming an authorized construction outreach trainer step by step.
