Do I Have To Maintain An OSHA 300 Log?

The OSHA 300 -- "Log of Work-Related Injuries and Illnesses" -- is a record of every work-related injury or illness that involves a

  • loss of consciousness
  • restricted work activity or job transfer
  • days away from work
  • medical treatment beyond first aid
  • significant work-related injuries or illnesses that are diagnosed by a licensed health care professional.
  • Other work-related injuries or illnesses listed in the OSHA regulation

Usually, most businesses with ten or fewer employees do not have to keep an OSHA 300 log.

  • (Exception: if WISHA, OSHA or the BLS has notified you in writing that you have to.)

Some businesses with more than ten employees are also exempt -- those specifically listed in WAC 296-27-00105 (1)(a) (260 KB PDF) as being in low hazard retail, service, finance, insurance or real estate industries.

If your company is not exempt, then you should obtain a copy of the OSHA 300 Recordkeeping Forms (www.OSHA.gov).

Whether a specific injury or illness needs to be recorded on the log is determined by a decision tree that OSHA has designed:
