Do I Have to Have and 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, for each calendar year, that involves

  • death;
  • loss of consciousness for any length of time;
  • restricted work activity or job transfer;
  • days away from work;
  • medical treatment beyond first aid; and
  • significant work-related injuries or illnesses (such as cancer, chronic irreversible disease, a fractured or cracked bone, or a punctured eardrum)  that are diagnosed by a licensed health care professional.

You are exempt from the OSHA recordkeeping requirements only if

  • you have ten (10) or less employees at all times during the calendar year, unless you are informed in writing from the Bureau of Labor Statistics (BLS), OSHA, or DOSH requiring you to comply. Note: Employee count includes employees at all of your business locations combined; or
  • your business establishment, by 4-digit NAICS, is on the industry exemption list in Table-1 under WAC 296-27-00105 (258 KB PDF).

If your company is not exempt, you should obtain a copy of the OSHA 300 Recordkeeping Forms (
