OSHA Recordkeeping

Post your OSHA 300 Log February 1 to April 30

January 10, 2018

First Aid KitThe Occupational Safety and Health Administration’s (OSHA’s) recordkeeping requirements are designed to help employers recognize workplace hazards by keeping track of work-related injuries and illnesses.

Most employers are required to prepare and maintain an injury and illness record call the OSHA 300 Log. Although not all injuries are required to be recorded on your OSHA 300 Log, OSHA recordkeeping includes work-related injuries and illnesses that involve:

  • Death
  • Days away from work
  • Restricted work or job transfer
  • Medical treatment beyond first aid
  • Loss of consciousness
  • Diagnosis by a healthcare professional as a significant injury or illness

Knowing whether or not to record an injury on your OSHA Log can be tricky. To help you make the determination, OSHA offers a web tool called the OSHA Recordkeeping Advisor.

Recordkeeping Tips

As you prepare your OSHA 300 Logs for posting, use these tips as guidance.

  • Complete your OSHA 300 Log and post 300A summary form February 1 to April 30.
  • Post your log where employees can see it, even if there were no recordable work-related injuries or illnesses during the year.
  • Keep your OSHA Logs up-to-date throughout the year. Completing your log last minute can be a daunting task.
  • Remember, OSHA counts calendar days beginning the day after the incident occurs.
  • Use the OSHA Recordkeeping Advisor as your guide when you question whether an injury is recordable on your log.
  • When you still can’t decide whether to record an injury on your log, contact your local MMA consultant for assistance.
  • Keep your forms and logs for five years.

Reporting injuries to OSHA

It is recommended that you report all work injuries to your workers’ compensation insurer. However, work injuries do not need to be reported to OSHA unless they involve death or catastrophic injuries. Work fatalities occurring within 30 days of the incident must be reported to OSHA within eight hours. Work-related hospitalizations, amputations and loss of eye must be reported to OSHA within 24 hours. You can report injuries to OSHA at 1-800-321-OSHA.

Online submission of OSHA Log

OSHA is also beginning to phase in a requirement that employers with 250 or more employees, or those with 20 or more employees in certain high-risk industries, submit recordable injury and illness data electronically. As of this post, the state of Minnesota is not yet requiring online reporting of OSHA 300 Logs. We encourage you to watch OSHA’s recordkeeping website for more information on these requirements.
