Osha Recordkeeping Requirements Explained: Full Guide

OSHA recordkeeping requirements determine which workplace injuries and illnesses your company must formally track, and getting them wrong can mean fines or missed safety trends. The rules hinge on a few key distinctions: who qualifies for exemptions, which forms apply to which situations, and what actually counts as a recordable case versus routine first aid. This article breaks down who must keep records, which forms to use, what counts as recordable, and how to stay compliant year-round.

Who Is Required to Keep OSHA Records

Most employers assume that recordkeeping obligations scale with risk, but company size plays just as large a role. Under OSHA's partial exemption, businesses that had 10 or fewer employees at all times during the previous calendar year generally do not need to maintain Form 300 logs, regardless of industry. That exemption is based on the peak employee count for the entire company, not a single location, so a business with multiple small sites can still be covered if the combined headcount exceeds the threshold.

A second exemption applies to specific low-hazard industries, regardless of size. OSHA maintains this list in Appendix A to Subpart B of the recordkeeping regulation, and it includes sectors such as certain retail establishments, real estate offices, insurance agencies, and some service industries where injury rates have historically been low. Because OSHA periodically reviews and updates this list based on injury data, employers should verify their current classification against the official Appendix A on OSHA's website as of 2026 rather than relying on older summaries or industry assumptions.

Even when a company qualifies for a full exemption from routine recordkeeping, that exemption does not extend to incident reporting. Every employer, exempt or not, must report certain severe events directly to OSHA within specific timeframes: any workplace fatality within 8 hours, and any in-patient hospitalization, amputation, or loss of an eye within 24 hours. This is where confusion often sets in. Recordkeeping refers to the ongoing logs a covered employer maintains internally. Reporting refers to the direct, time-sensitive notification of severe incidents to OSHA, and it applies universally. A company with five employees in an exempt industry still has to pick up the phone if a worker loses a limb on the job.

Before assuming your company is off the hook, confirm both your employee count history and your industry classification. Misreading either one is one of the most common compliance gaps safety coordinators encounter during audits.

The Core Forms: 300, 300A, and 301

Covered employers rely on three interconnected forms, each serving a distinct purpose in the recordkeeping process. Understanding how they relate makes the whole system far less confusing.

Form 300, the Log of Work-Related Injuries and Illnesses, functions as the running record. Every time a recordable incident occurs, it gets logged here with details like the employee's job title, the date and location of the incident, and a brief description of the injury or illness. This form is updated continuously throughout the year as new cases arise or existing case classifications change.

Form 300A is the annual summary, a tally of the totals from the Form 300 log covering the entire prior calendar year. This is the document most employees will actually see, because OSHA requires it to be posted in a visible, common area of the workplace, such as a break room or bulletin board, from February 1 through April 30 each year. Before posting, a company executive must review the data and certify its accuracy, a step that is easy to overlook but carries real weight if the summary is later found incomplete or incorrect.

Form 301, the Injury and Illness Incident Report, captures the details of a single specific case. Employers must complete this form within 7 calendar days of learning that a recordable injury or illness occurred. It asks for more granular information than the log, including how the incident happened, what the employee was doing at the time, and what treatment was provided. Some employers use equivalent forms, such as workers' compensation paperwork, as long as those forms contain the same information required by Form 301.

Together, these three forms create a paper trail that moves from individual incident, to running log, to annual summary. Missing any one piece breaks that chain and can leave a company unable to demonstrate compliance during an inspection.

What Counts as a Recordable Injury or Illness

OSHA's general recording criteria are more specific than most people assume. A case is recordable if it results in death, days away from work, restricted work activity or job transfer, medical treatment beyond first aid, loss of consciousness, or a significant injury or illness diagnosed by a physician or licensed health care professional, even if it doesn't fall into the other categories.

The line between "medical treatment" and "first aid" is where most classification errors happen. Stitches, prescription-strength medication, professional wound cleaning and irrigation, and rigid immobilization with a brace or splint all count as medical treatment, which makes the case recordable. On the other hand, cleaning a wound and applying a bandage, giving over-the-counter pain medication at nonprescription strength, using a hot or cold pack, and applying a simple bandage or non-rigid support are all classified as first aid, and cases limited to these treatments are not recordable. The distinction isn't about how serious an injury looks, it's about the specific treatment provided.

This creates a common misconception: that any injury occurring on the job must be logged on Form 300. In reality, a large share of everyday workplace incidents, a small cut treated with a bandage, a minor bruise iced and monitored, a headache managed with an over-the-counter tablet, never rise to the level of a recordable case. The purpose of the recordable threshold is to capture injuries and illnesses serious enough to affect an employee's work status or require professional medical intervention, not every scrape that happens during a shift.

Safety coordinators should train supervisors and first responders on-site to document the treatment given, not just the injury itself, since that detail determines whether the case belongs on the log. A workplace with a strong CPR and first aid trained staff is often better positioned here, because trained responders tend to document care more precisely and can distinguish between appropriate first aid and situations that clearly require a higher level of medical attention.

Electronic Reporting and ITA Submission Deadlines

Beyond maintaining physical or digital copies of Forms 300, 300A, and 301, certain establishments must also submit portions of their injury and illness data electronically through OSHA's Injury Tracking Application, commonly referred to as the ITA. This requirement exists separately from the standard recordkeeping obligation and is based on establishment size and industry classification rather than total company headcount alone.

Generally, establishments with 250 or more employees that are already required to keep records, along with smaller establishments of 20 to 249 employees in designated high-hazard industries, fall under the electronic submission mandate. However, these thresholds and the specific data fields required have shifted with rule changes in recent years, so employers should confirm the current requirements directly on OSHA's website rather than relying on outdated guidance.
