Each year, U.S. businesses must submit their federal injury and illness logs to OSHA. This process is commonly referred to by the form used to collect data: OSHA 300.
OSHA collects this data to help identify establishments with specific hazards so it can initiate enforcement and provide outreach activities to address and abate hazards. This same data also allows OSHA to better analyze trends related to specific industries, processes, or hazards with an ultimate goal to reduce occupational injuries and illnesses.
This installment of Work Safety 101 explains how to follow OSHA’s annual injury and illness reporting process, including who must report, due dates, exemptions, additional requirements for certain injuries, and how to submit.
Federal injury and illness record keeping is regulated by 29 CFR §1904 - Recording and Reporting Occupational Injuries and Illnesses. There are three important forms:
While all businesses must keep their own internal injury and illness records in compliance with 29 CFR §1904, not everyone is required to electronically submit data annually. Only establishments within these three categories must submit data:
| Employees during previous calendar year |
Industries included |
Submit data from forms |
|---|---|---|
| 250 or more | All not exempted (see below) | 300A |
| 20-249 | Appendix A | 300A |
| 100 or more | Appendix B | 300, 300A, 301 |
Appendices A and B include, but are not limited to:
If any part of your business does not fall into any of these three categories, then you must submit information only if OSHA requests individual data collection.
Under OSHA’s regulations, an "establishment" is a single physical location where business is conducted or services/industrial operations are performed. A "firm" may comprise one or more establishments.
If a company has several business establishments engaged in different classes of business activities, some establishments may be required to keep records, while others may be exempt.
A firm with more than one establishment must submit injury and illness data specific to each establishment that meets the size and industry reporting criteria, but can do so using one account.
Unless OSHA or the Bureau of Labor Statistics (BLS) informs you in writing that you must keep records, the following criteria exempt establishments from reporting:
All employers must report to OSHA any workplace incident that results in an employee's fatality, in-patient hospitalization, amputation, or loss of an eye regardless of exemptions.
Under the regulation’s general criteria, injuries and illnesses are recordable if they result in:
Additional information is required for:
Covered establishments must submit their annual 300A, 300, and 301 data to the Injury Tracking Application (ITA). OSHA does not accept completed paper forms by mail or electronic forms by email.
While the PDF forms on OSHA’s website can be used to meet recording requirements, they cannot be submitted to the ITA. You must enter the information through the ITA web form, create a CSV file in the required format, or use an application programming interface (API).
If you are submitting data for one or only a few establishments, OSHA recommends that you use the 300A web form rather than using the CSV upload option.
OSHA does not collect:
Establishments should remove non-mandatory information that could reasonably be expected to identify individuals from the narrative fields in forms 300 and 301 before submitting them to the ITA.
Covered employers must save forms 300, 300A, 301, and the privacy case list (if one exists) for five years.
If requested, copies of these records must be provided to current and former employees, or their representatives, as well as to OSHA.
Separate from the ITA submission, Form 300A must be physically posted in a conspicuous place in each establishment from Feb. 1 through April 30 of the year following the year covered by the records.
