Accident Reporting at Work: OSHA Deadlines, Forms, and Retaliation

Accident reporting at work follows two overlapping sets of OSHA rules and deadlines: employers must notify OSHA within 8 hours of a workplace fatality and within 24 hours of an inpatient hospitalization, amputation, or loss of an eye, and they must record most other work-related injuries on internal OSHA forms within 7 calendar days.¹ Injured workers have a separate obligation: tell a supervisor as soon as possible, because that notice both feeds the OSHA record and starts the workers’ compensation clock. Missing any of these deadlines carries real consequences, including federal penalties up to $16,550 per violation and, for workers, a denied comp claim.

What the Injured Worker Should Do First

Get medical attention before anything else. If someone is seriously hurt, call 911 or go to an emergency room; paperwork can wait until the person is stable. Once the immediate danger passes, the injured worker should tell a supervisor about the incident the same day. Verbal notice on the day of the accident is the standard most employers expect, and many internal policies set a formal window of 24 to 48 hours.

Follow the verbal notice with something in writing. Even if your employer says a conversation is enough, a written record protects you if there’s ever a dispute about when or whether you reported. Include the date, time, location, what happened, and what part of your body was injured. Keep a copy for yourself. That same document usually becomes the foundation of any workers’ compensation claim you file later.

OSHA’s Deadlines for Severe Incidents

Internal timelines are set by company policy, but federal law imposes hard deadlines when an incident is serious. Employers must notify OSHA within 8 hours of any workplace fatality.¹ For incidents involving an inpatient hospitalization, an amputation, or the loss of an eye, the deadline is 24 hours.² The clock starts from the moment the employer learns of the event, not from when someone sits down to fill out a form.

There are three ways to make the report: call the nearest OSHA area office, use the 24-hour hotline at 1-800-321-6742, or file online through OSHA’s website.³ If the local area office is closed, an employer cannot leave a voicemail or send an email and wait until morning. They must use the hotline or the online portal.

Penalties adjust for inflation each year. As of 2026, a serious or other-than-serious violation can cost up to $16,550 per occurrence, while willful or repeated violations can reach $165,514. OSHA issues these fines routinely, and the amounts grow when an employer’s overall response shows a pattern of indifference.

Which Injuries Have to Be Recorded

Not every workplace injury has to be recorded. The line between a recordable injury and one that only needs basic first aid is one of the most misunderstood parts of the process, and getting it wrong in either direction causes problems. Recording too much inflates your incident rate; missing a recordable case invites a citation.

A work-related injury or illness is recordable if it results in any of the following:⁴

Death from a work-related cause.
At least one day away from work beyond the day of injury.
Restricted work or a job transfer.
Medical treatment beyond first aid.
Loss of consciousness, regardless of duration.
A physician’s diagnosis of cancer, a chronic irreversible disease, a fractured bone, or a punctured eardrum, even if no other criteria are met.

The dividing line in most cases is that phrase “medical treatment beyond first aid.” If a worker cuts a hand and a supervisor cleans the wound and applies a bandage, that’s first aid. If the worker needs stitches at an urgent care clinic, that’s medical treatment, and the case is recordable. Prescription medications, physical therapy, and surgical procedures all count as medical treatment. Non-prescription painkillers, tetanus shots, and simple wound cleaning do not.

Counting Days Away and Restricted Work

When counting days away from work, skip the day of the injury and count only calendar days the employee was scheduled to work.⁵ Holidays and vacation days don’t count. The count stops if the employee is terminated for reasons unrelated to the injury.

Restricted work means the employer keeps the employee from doing tasks they’d normally perform at least once a week.⁶ A doctor’s note imposing a lifting restriction doesn’t automatically make a case recordable. If the employee’s normal duties never require heavy lifting, the restriction doesn’t prevent them from doing their routine work, so the case wouldn’t qualify.

The Forms and Their Deadlines

The primary incident-level document is OSHA Form 301, the Injury and Illness Incident Report.⁷ An equivalent form, such as a state workers’ compensation first report of injury, is acceptable as long as it captures the same information. Form 301 asks for the employee’s identifying details, the time the shift began and the exact time of the incident, what the employee was doing immediately before the injury, the tools or materials involved, the specific body part affected and the object that caused the harm, the type of injury, and a narrative of how the event unfolded.

The form must be completed within 7 calendar days of receiving information that a case is recordable.⁷ Accuracy matters here. Vague entries like “employee hurt back” are the kind of language that draws scrutiny during an OSHA inspection.

Beyond individual incident reports, employers maintain a running log that tracks every recordable injury and illness during the year. OSHA Form 300, the Log of Work-Related Injuries and Illnesses, serves this purpose.⁷ Each new recordable case has to be added within 7 calendar days of the employer learning about it.

At year’s end, the employer totals up the Form 300 data into a summary on Form 300A. A senior company executive must review and certify the summary, then post it at each worksite from February 1 through April 30 of the following year, even if no injuries or illnesses occurred that year. All three forms, the 300 Log, the 300A Summary, and every 301 Incident Report, have to be kept for 5 years after the end of the calendar year they cover.⁸

Electronic Submission to OSHA

Many employers also have to submit their injury data electronically to OSHA through the Injury Tracking Application.⁹ OSHA does not accept paper forms by mail or electronic forms by email.¹⁰ The thresholds depend on establishment size and industry:

Establishments with 250 or more employees submit Form 300A data annually, regardless of industry.¹¹
Establishments with 100 or more employees in certain high-hazard industries submit detailed Form 300 and Form 301 data annually.
Establishments with 20 to 249 employees in designated industries submit Form 300A summary data annually.¹²

The designated industries include manufacturing, construction, utilities, agriculture, wholesale trade, certain retail sectors, transportation, warehousing, healthcare, and waste management, among others. Employee counts include part-time, seasonal, and temporary workers. The annual submission deadline for 2026 data is early March of the following year.⁹

Who Is Exempt From Routine Recordkeeping

Two groups get a partial pass. Companies with 10 or fewer employees at all times during the previous calendar year are exempt from maintaining the 300 Log, 300A Summary, and 301 forms.¹³ The count is company-wide, not per location. If the company hit 11 employees at any point during the year, the exemption disappears. Certain low-hazard industries, such as some retail and professional services, also qualify for a partial exemption regardless of size.

The word “partial” is doing real work in that sentence. Even exempt employers still have to report fatalities, hospitalizations, amputations, and eye losses to OSHA within the standard 8-hour or 24-hour deadlines.¹³ Small size does not excuse an employer from calling OSHA after a serious injury.

State-Plan States Can Add More

About half the states operate their own OSHA-approved safety and health programs. State plans must meet or exceed federal standards, and most adopt the federal recordkeeping rules unchanged. A few states, with California the most prominent example, impose stricter requirements or additional reporting obligations. If you work in a state-plan state, check whether your state labor agency has separate forms or shorter deadlines. The federal rules described here are the floor every state has to meet.

Retaliation Protection and the 30-Day Clock

Federal law makes it illegal for an employer to fire, demote, or punish a worker for reporting a workplace injury. Section 11(c) of the Occupational Safety and Health Act prohibits discrimination against an employee who files a safety complaint, reports an injury, or participates in an OSHA proceeding.¹⁴ This covers obvious retaliation like termination, and it also reaches subtler tactics: cutting hours, reassigning someone to undesirable shifts, sudden negative performance reviews, or exclusion from meetings and promotion opportunities.

If you believe your employer retaliated against you for reporting an accident, you have 30 days from the retaliatory action to file a complaint with OSHA.¹⁴ OSHA investigates, and if it finds a violation it can file a federal court action seeking reinstatement to your former position with back pay. The 30-day deadline is unforgiving. Once it passes, the federal Section 11(c) claim is gone, no matter how clear the retaliation was. Some states offer longer windows under their own whistleblower laws, but the federal clock runs regardless.

How the Report Connects to Workers’ Compensation

The accident report you file with your employer does double duty. It satisfies the internal safety documentation requirement and, in most states, it also serves as the notice that triggers your right to workers’ compensation benefits. Failing to report promptly can jeopardize a claim. Most states require you to notify your employer within 30 to 60 days of an injury, and a few set deadlines as short as a few days. The statute of limitations for filing a formal claim with your state’s workers’ compensation board is longer, generally one to three years depending on the state.

Once the employer has notice of an injury that requires medical treatment or causes missed work, the employer is typically required to report it to their workers’ compensation insurance carrier. The insurer then decides whether to accept or dispute the claim. The quality of the initial accident report, the specificity of what happened, the documented witnesses, the medical records from the first treatment, often determines whether a claim moves smoothly or stalls.

Workers’ compensation benefits generally cover reasonable medical treatment related to the injury plus a portion of lost wages during recovery. Most states pay about two-thirds of average weekly wage, subject to a state-set maximum that varies widely. Waiting periods of three to seven days before wage-replacement checks begin are standard, though many states pay retroactively for those initial days if the disability extends beyond a set threshold. Workers’ compensation is a no-fault system: you don’t need to prove your employer was negligent, only that the injury happened at work. In exchange, comp is typically the exclusive remedy, meaning you can’t sue your employer for the same injury in most circumstances.
