All employers in Washington State are required to report to the Washington State Department of Labor and Industries (L&I) Division of Occupational Safety and Health (DOSH), any work-related incident that results in a fatality, in-patient hospitalization, amputation, or loss of any eye of any employee.

Most employers are required to record workplace injuries and illnesses on an OSHA 300 log ( Such information can be used to identify hazards and refine your workplace health and safety programs. You'll need to review the rules on this page to determine which recordkeeping and reporting requirements apply to your workplace.

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 is included by 4-digit North American Industrial Classification System (NAICS) code on the industry exemption list in Table-1 under WAC 296-27-00105 (600 KB PDF).

To determine your NAICS code, do one of the following:

  • Contact your nearest OSHA office, or call L&I DOSH at 1-800-423-7233.
  • Use the NAICS search feature ( at the U.S. Census Bureau NAICS main page. In the search box for the most recent NAICS, enter a keyword that describes your type of business. A list of primary business activities containing that keyword and the corresponding NAICS codes will appear. Choose the one that most closely corresponds to your primary business activity or refine your search to obtain other choices.
  • Rather than searching through a list of primary business activities, you can view the most recent complete NAICS structure with codes and titles ( by clicking on the link for the most recent NAICS on the U.S. Census Bureau NAICS main page, then click the 2-digit sector code to see all the NAICS codes under that sector. Then choose the 6-digit code of your interest to see the corresponding definition as well as cross-references and index items, when available.
  • If you know your old Standard Industrial Classification (SIC) code, you can find the appropriate 2002 NAICS code (609 KB PDF) ( by using the detailed conversion (concordance) between the 1987 SIC and 2002 NAICS.  

At the end of each calendar year, employers who are required to keep OSHA 300 Injury and Illness Recordkeeping Logs must compile the information on the OSHA Form 300A (annual summary) or an equivalent form. This annual summary is required to be posted in a conspicuous place or places where notices to employees are customarily posted. This annual summary must be posted from February 1 through April 30 of each year.

The recordkeeping and reporting information found on this page is separate and distinct from the Workers' Compensation requirements under the Industrial Insurance Act under Title 51 RCW. For information on those requirements, go to Workers' Compensation Record Keeping and Reporting Guides (F212-222-000).
