OSHA 300 Log Requirements: Complete Employer Guide

The OSHA 300 Log is one of the most important workplace safety records required by the Occupational Safety and Health Administration (OSHA). Many employers must maintain this log to document work-related injuries and illnesses throughout the year.

Accurate recordkeeping helps employers identify workplace hazards, improve safety programs, and demonstrate compliance during OSHA inspections. Failure to properly maintain required records may result in citations and penalties.

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 the OSHA 300 Log?

The OSHA 300 Log, officially called the Log of Work-Related Injuries and Illnesses, is used to record qualifying workplace injuries and illnesses that occur during a calendar year.

The OSHA recordkeeping system consists of three primary forms:

  • OSHA Form 300 – Log of Work-Related Injuries and Illnesses
  • OSHA Form 300A – Summary of Work-Related Injuries and Illnesses
  • OSHA Form 301 – Injury and Illness Incident Report

Each form serves a different purpose and together they help employers maintain complete workplace injury records.

Who Must Keep an OSHA 300 Log?

Many employers with more than 10 employees are required to maintain OSHA injury and illness records unless they qualify for a partial exemption.

Industries that commonly maintain OSHA logs include:

  • Manufacturing
  • Warehousing
  • Distribution Centers
  • Construction
  • Healthcare
  • Transportation
  • Wholesale Businesses
  • Food Processing
  • Industrial Facilities
  • Utility Companies

Certain low-hazard industries may qualify for OSHA's partial recordkeeping exemption. However, exempt employers may still have reporting obligations for serious workplace incidents.

Which Injuries Must Be Recorded?

Generally, a workplace injury or illness must be recorded if it is work-related and results in one or more of the following:

  • Death
  • Days away from work
  • Restricted work activity
  • Job transfer
  • Medical treatment beyond first aid
  • Loss of consciousness
  • A significant injury or illness diagnosed by a licensed healthcare professional

Each incident should be evaluated using OSHA's official recordkeeping criteria.

Examples of Recordable Injuries

Examples include:

  • An employee slips on a warehouse floor and fractures a wrist.
  • A machine accident requires stitches.
  • A worker suffers chemical exposure requiring medical treatment.
  • An employee develops work-related hearing loss that meets OSHA recording criteria.
  • An employee misses several workdays after a workplace injury.

Examples That May Not Be Recordable

Some incidents generally are not recordable, including:

  • First aid only treatment
  • Common cold or seasonal influenza
  • Minor cuts requiring only a bandage
  • Personal medical conditions unrelated to work
  • Injuries occurring outside the workplace without a work-related cause

When in doubt, employers should review OSHA guidance before making a recording decision.

When Must the OSHA 300 Log Be Updated?

Recordable injuries and illnesses should generally be entered on the OSHA 300 Log within seven calendar days after the employer learns that the case meets OSHA's recording requirements.

Maintaining current records helps employers remain compliant and better manage workplace safety.

How Long Must OSHA Records Be Kept?

Employers generally must retain:

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

for five years following the end of the calendar year covered by the records.

During the retention period, employers should update records if new information becomes available regarding a recorded case.

OSHA 300 Log vs. OSHA 300A Summary

These forms are often confused but serve different purposes.

OSHA Form 300

A detailed log containing every recordable workplace injury and illness.

OSHA Form 300A

An annual summary that totals injuries and illnesses recorded during the year. Employers that are required to maintain OSHA records generally must post the completed OSHA 300A Summary in a visible workplace location during OSHA's required posting period.

Common Employer Recordkeeping Mistakes

Employers frequently make mistakes such as:

  • Recording injuries too late
  • Failing to record qualifying injuries
  • Recording injuries that are not OSHA recordable
  • Miscalculating days away from work
  • Losing required documentation
  • Forgetting annual reviews
  • Not training supervisors on reporting procedures

Proper recordkeeping helps avoid compliance issues during OSHA inspections.

Best Practices for OSHA Recordkeeping

Employers can improve compliance by:

  • Reporting incidents immediately
  • Training supervisors on OSHA recordkeeping rules
  • Conducting prompt accident investigations
  • Reviewing records monthly
  • Keeping supporting medical documentation
  • Looking for injury trends that indicate safety improvements are needed

Good recordkeeping is an important component of an effective workplace safety program.
