Accurate recordkeeping is crucial for identifying potential hazards, tracking trends in injuries and illnesses, and implementing effective measures to prevent future incidents. Recordkeeping is not only essential for workplace safety but also imperative for compliance with regulatory standards, ensuring that businesses adhere to legal requirements and avoid potential penalties or fines.

At the heart of this effort lies the OSHA 300A Log—a vital document that summarizes a year’s worth of occupational incidents. But what exactly is the OSHA 300A Log, and why is it so crucial for businesses? In this comprehensive guide, we delve into the essentials of OSHA 300A Logs, from what information they entail to who is responsible for posting them. Whether you’re a seasoned safety manager or new to the world of workplace compliance, understanding OSHA 300A Logs is essential for maintaining a safe and healthy work environment.

What is an OSHA 300A Log?

The OSHA 300A Log is an annual summary of all OSHA recordable incidents at each business location.

The OSHA 300A Log of the previous year’s incidents must be posted for employees to view at each job site from February 1 to April 30. During this period, employees have the opportunity to review the log, fostering transparency and awareness regarding workplace safety within the organization. By allowing employees to review the log, businesses not only promote transparency but also empower their workforce to actively participate in maintaining a safe and healthy work environment.

What Information Must be Recorded on the OSHA 300A Log?

OSHA requires that specific information be provided to employees on this log, including the total number of OSHA recordable incidents, total number of hours worked, total number of missed and restricted days, injury and illness types, and identifying company data. This data not only helps in understanding the nature and extent of workplace injuries and illnesses but also aids in devising targeted strategies for prevention and mitigation.

What Employers Must Maintain and Post an OSHA 300A Log?

Employers with over ten employees not in partially exempt industries must keep OSHA recordkeeping logs to track information on recordable injuries and illnesses. Unsure of whether your industry is required to complete OSHA recordkeeping? The full list of partially exempt industries can be found in Appendix A to 29 CFR 1904.

Remember! Even locations that do not have any OSHA recordable incidents are still required to post their OSHA 300A Logs.

Who is Authorized to Post an OSHA 300A Log?

It’s common for companies to be unsure about who is responsible for posting and maintaining accessibility of the form for staff. OSHA rules dictate that the responsible party should be a company executive. According to The National Law Review, there are four main criteria for determining who is a company executive:

  • An owner of the company (only if the company is a sole proprietorship or partnership);
  • An officer of the corporation;
  • The highest-ranking company official working at the establishment; or
  • The immediate supervisor of the highest-ranking company official working at the establishment.

If you’re an employer subject to OSHA’s recordkeeping regulations, it’s important to make sure that the responsibility for posting the OSHA 300A form is clearly delineated. This will ensure that the form is posted, helping your company to avoid any possible punitive fines from the agency.

Certifying and Posting an OSHA 300A Log

At the end of each calendar year, you must review the OSHA 300A Log to verify that the entries are complete and accurate, and correct any deficiencies identified. The OSHA Standard states that:

“A company executive must certify that he or she has examined the OSHA 300A Log and that he or she reasonably believes, based on his or her knowledge of the process by which the information was recorded, that that annual summary is correct and complete.”

Additionally, you must post the 300A Summary of each establishment from Feb 1 to April 30 with the summary data from the previous year. The summary must be posted in a conspicuous place where notices to employees are customarily posted. You must also make sure that the summary is not altered, defaced, or covered by other material.

What Data Do I Need to Electronically Submit to OSHA?

In 2023, OSHA published a Final Rule that revised the recordkeeping regulation to require certain establishments with 100 or more employees in high-hazard industries, which were already required to submit information from the OSHA Form 300A Annual Summary, to also submit information from the OSHA Form 300 Log and the OSHA Form 301 Incident Report.

This update underscores the importance of thorough electronic submission, ensuring comprehensive reporting of workplace incidents and enhancing transparency for regulatory oversight.
