What is the BLSI?

BLSI stands for the Bureau of Labor Statistics Information. This group gathers and distributes data on fatal and nonfatal occupational injuries and illnesses.

The group assigns North American Industry Classification System (NAICS) codes to all employer accounts. These codes enable researchers to draw current statistics related to Washington State workplace safety and health.


Which reports do the BLSI laber statistics come from?

The data for the reports on this page are from these U.S. Department of Labor's Bureau of Labor Statistics (BLS) national reports:

  • BLS Annual Survey of Occupational Injuries and Illnesses.
  • BLS Census of Fatal Occupational Injuries.

Data for these reports are gathered through a cooperative effort between the federal Bureau of Labor Statistics and L&I's Bureau of Labor Statistics Information section (BLSI).

Fatality data is gathered through the U.S. Census of Fatal Occupational Injuries program (CFOI) (stats.bls.gov).

Nonfatal data is gathered through an annual survey.


Which classification system does the survey of occupational injuries and illnesses use?

The current survey of occupational injuries and illnesses uses the North American Industrial Classification System (NAICS).

Prior to 2003, the survey used the Standard Industrial Classification system coding (SIC).

The substantial differences between the 2 coding systems result in breaks in series for industry data.

Users are advised against making comparisons between current industry categories (2003 and later) and the results from years prior to 2003.
