OSHA 300A Summary Requirements: Complete Employer Guide

The OSHA 300A Summary is an annual summary of work-related injuries and illnesses that many employers are required to prepare and display each year. Unlike the OSHA 300 Log, which contains detailed information about individual cases, the OSHA 300A provides a yearly summary of recordable workplace injuries and illnesses.

Properly completing and posting the OSHA 300A Summary helps employers comply with federal OSHA regulations while providing employees with important information about workplace safety.

Stay OSHA & Labor Law Compliant

Maintaining OSHA records is only one part of workplace compliance. Most employers are also required to display current Federal and State Labor Law Posters where employees can easily read them.

What Is OSHA Form 300A?

OSHA Form 300A is the Summary of Work-Related Injuries and Illnesses for a calendar year.

Instead of listing every injury, the form summarizes:

  • Total deaths
  • Total cases with days away from work
  • Total restricted duty or job transfer cases
  • Total recordable injuries and illnesses
  • Total days away from work
  • Total restricted workdays
  • Average number of employees
  • Total hours worked during the year

The information is compiled from the OSHA 300 Log.

Who Must Complete OSHA Form 300A?

Many employers with more than 10 employees that are subject to OSHA recordkeeping requirements must complete OSHA Form 300A annually.

Industries commonly required to complete the form include:

  • Manufacturing
  • Warehousing
  • Construction
  • Transportation
  • Healthcare
  • Distribution Centers
  • Wholesale Businesses
  • Industrial Operations

Some low-hazard industries may qualify for partial exemptions.

When Must the OSHA 300A Summary Be Posted?

Employers that are required to maintain OSHA records generally must post the completed OSHA 300A Summary from February 1 through April 30 each year.

The summary reflects workplace injuries and illnesses from the previous calendar year.

Where Must OSHA Form 300A Be Posted?

The OSHA 300A Summary should be displayed in a conspicuous location where employee notices are normally posted.

Common locations include:

  • Employee break rooms
  • Time clock areas
  • HR bulletin boards
  • Employee entrances
  • Lunch rooms
  • Safety information boards

Employees should be able to review the summary without asking permission.

Who Must Sign the OSHA 300A Summary?

Before posting, the summary generally must be certified by a company executive, such as:

  • Business owner
  • Corporate officer
  • Highest-ranking official at the establishment
  • Immediate supervisor of the highest-ranking official

Unsigned summaries do not satisfy OSHA's certification requirement.

Is the OSHA 300A Submitted to OSHA?

Some employers are required to electronically submit OSHA injury and illness data based on establishment size and industry classification.

Electronic submission requirements are separate from the obligation to post the OSHA 300A Summary in the workplace.

Employers should review current OSHA electronic reporting requirements to determine whether they must submit data online.

Common Employer Mistakes

Common errors include:

  • Forgetting to post the summary
  • Missing the February 1 posting deadline
  • Removing the summary before April 30
  • Posting an unsigned form
  • Incorrect injury totals
  • Using incomplete OSHA 300 records

Routine annual reviews help reduce compliance mistakes.

Best Practices

To remain compliant:

  • Review OSHA records before year-end.
  • Verify injury totals.
  • Have an executive certify the form.
  • Post the summary by February 1.
  • Leave the summary posted through April 30.
  • Retain OSHA records for the required retention period.

Maintaining organized records simplifies OSHA compliance and inspection readiness.

Related OSHA Forms

Employers should understand the differences between:

  • OSHA Form 300
  • OSHA Form 300A
  • OSHA Form 301

Together, these forms make up OSHA's workplace injury and illness recordkeeping system.
