Learn How to File an OSHA Complaint

Understanding OSHA and Workplace Safety Complaints

The Occupational Safety and Health Administration (OSHA) is a federal agency created in 1970 to protect workers from unsafe and unhealthful working conditions. OSHA operates under the Department of Labor and has the authority to investigate workplace hazards reported by employees, unions, and other parties. When workers believe their workplace violates safety regulations, OSHA provides a formal process for reporting these concerns.

OSHA's role focuses on enforcing workplace safety standards across nearly all private employers in the United States. The agency maintains specific rules about everything from fall protection on construction sites to chemical handling in manufacturing plants. These standards exist because unsafe workplaces cause real harm—according to the Bureau of Labor Statistics, there were 5.5 million nonfatal workplace injuries and illnesses in 2022 alone. Workers have the right under Section 11(c) of the Occupational Safety and Health Act to report safety violations without fear of retaliation.

Understanding what OSHA does and doesn't do matters before filing a complaint. OSHA investigates safety and health hazards, not wage disputes, discrimination claims, or contract disagreements. For those issues, other agencies handle complaints. OSHA also doesn't handle worker's compensation claims or personal injury lawsuits. The agency employs compliance officers who conduct workplace inspections and gather evidence about alleged violations. These inspections can result in citations and fines for employers who violate standards.

Workers should know that filing an OSHA complaint is a straightforward process available to any employee concerned about workplace safety. The process is confidential when requested, meaning OSHA will not reveal a worker's name to the employer during certain types of investigations. This protection encourages workers to report serious hazards without worrying about negative consequences. Understanding the basics of how OSHA operates provides context for why and how to file a complaint.

Practical Takeaway: Before filing a complaint, confirm that your concern involves a workplace safety or health issue within OSHA's authority. Review the OSHA standards related to your industry to understand what regulations may apply to your situation.

Identifying Workplace Hazards That OSHA Investigates

Not every workplace problem qualifies for an OSHA complaint. OSHA focuses specifically on safety and health hazards—conditions that could cause injury or illness. Common hazards OSHA investigates include falls from heights, electrical hazards, chemical exposure, machinery without proper guards, respiratory hazards from dust or fumes, and unsafe lifting practices. In construction, fall protection violations are among the most frequently cited hazards. In healthcare settings, bloodborne pathogen exposure and ergonomic injuries are common concerns. Manufacturing facilities might have issues with locked-out machinery or chemical storage problems.

To determine if a hazard warrants an OSHA complaint, consider whether it poses a realistic risk of serious injury or death. A minor inconvenience or general discomfort usually doesn't meet this standard. However, a condition that could cause broken bones, loss of consciousness, or permanent injury does. For example, a worker standing on an unstable ladder eight feet above concrete flooring faces a serious hazard. A worker handling asbestos without respiratory protection faces a serious hazard. A worker in a warehouse where fire exits are blocked faces a serious hazard.

OSHA recognizes different levels of violations. A serious violation occurs when a hazard could cause serious physical harm or death. A willful violation occurs when an employer deliberately or with intentional disregard for the law violates a standard. A repeated violation occurs when an employer has previously been cited for the same hazard. A failure-to-abate violation occurs when an employer hasn't corrected a previously cited violation. Understanding these categories helps workers recognize the severity of what they've observed.

Workers should document the hazard they observe. Take note of specific details: What is the hazard? Where is it located? When does it occur? Who is affected? Has anyone been injured? Are there near-misses or close calls? How many workers are exposed? This documentation strengthens a complaint and provides OSHA investigators with concrete information. Photos or videos of hazards can be valuable evidence, though workers should prioritize their own safety when gathering this information.

Practical Takeaway: Review OSHA standards for your industry by visiting osha.gov and searching for industry-specific requirements. Document specific details about any hazard you observe, including dates, times, locations, and affected workers, before filing a complaint.

Methods for Filing an OSHA Complaint

OSHA provides multiple channels for filing a complaint about workplace safety hazards. The most common methods are online, by phone, by mail, or in person at a local OSHA office. Each method has advantages depending on a worker's situation and preferences. Understanding the different options allows workers to choose the approach that works best for them.

The online complaint process has become increasingly popular because it operates 24/7 and allows workers to file from any location with internet access. Workers visit osha.gov and locate the complaint submission form. The form requests information about the alleged hazard, the employer, the worker's contact information, and details about the hazard. Workers can choose whether to remain anonymous or provide their name. If a worker requests confidentiality, OSHA will not reveal the worker's identity to the employer. The online system provides a way to track the complaint's status and receive updates about the investigation.

The telephone method allows workers to speak directly with an OSHA representative who can answer questions and record complaint details. OSHA maintains a toll-free line: 1-800-321-OSHA (6742). Representatives answer calls during business hours and can provide guidance about whether a particular concern falls within OSHA's authority. This method works well for workers who prefer verbal communication or have questions about the complaint process. A representative can clarify what information OSHA needs and how the investigation will proceed.

The mail method involves sending a written complaint to the nearest OSHA office. Workers should include specific details about the hazard, the employer's name and address, and contact information. A worker can search for their regional OSHA office on osha.gov to find the correct mailing address. This method takes longer than online or phone filing because mail requires processing time, but it creates a paper record of the complaint. Some workers prefer this method for situations where they want written documentation.

The in-person method involves visiting a local OSHA office to file a complaint directly with an official. This approach allows for detailed discussion and immediate clarification of information. Some workers feel more comfortable discussing sensitive situations face-to-face. However, this method requires travel to an office during business hours, which may not be practical for all workers. A worker can call ahead to confirm office hours and location.

Practical Takeaway: Choose the filing method that best suits your situation. For most situations, the online method at osha.gov offers convenience and 24/7 access. For complex situations or if you have questions, calling the OSHA hotline allows you to speak with a representative who can guide your complaint.

Information and Documentation Needed for Your Complaint

OSHA requests specific information when processing a complaint to ensure investigators have what they need to assess the hazard. The more detail a worker provides, the easier it is for OSHA to understand the situation and conduct an appropriate investigation. While OSHA accepts complaints with incomplete information, comprehensive details strengthen the complaint and can lead to more thorough investigations.

Worker information includes the person's name, phone number, email address, and mailing address. A worker has the option to request confidentiality, in which case OSHA will mark the complaint accordingly. However, providing contact information allows OSHA investigators to follow up if they need clarification about the hazard or want to inform the worker about the investigation's outcome. Some workers worry about retaliation, but the law prohibits employers from punishing workers for reporting safety violations.

Employer information includes the employer's name, street address, city, state, and zip code. The more specific the location information, the better. For large companies with multiple facilities, specifying the exact location where the hazard exists helps OSHA send inspectors to the correct site. If the employer operates under a different legal name than what employees call it, providing both names reduces confusion. For smaller employers or contractors, accurate address information is essential because OSHA must locate the workplace to conduct an inspection.

Hazard information is the core of the complaint. A worker should describe the specific hazard, how it poses a risk, and where exactly it's located within the workplace. Rather than vague statements, specific details are
