Bureau of Labor Statistics Resources for Respondents 

The Survey of Occupational Injuries and Illnesses (SOII) 

The Survey of Occupational Injuries and Illnesses (SOII) is a nationwide survey of work establishments that is used by the U.S. Bureau of Labor Statistics (BLS) to determine state and national estimates of the number, rate, and characteristics of non-fatal work-related injuries and illnesses. In Colorado, the SOII data collection is a cooperative effort between BLS and the Colorado Department of Public Health and Environment (CDPHE).
The SOII is a separate program from the OSHA Electronic Submission of Injury and Illness Records program. The survey team at CDPHE that collects Colorado SOII responses is part of the Occupational Health and Industrial Hygiene Unit (OHIHU) within the Health Equity branch in the Division of Disease Control and Public Health Response. CDPHE is barred by federal law from sharing the survey responses with anyone who is not a BLS agent, including state and federal OSHA programs.
SOII also provides detailed information, including demographic data, for cases that involve one or more days away from work or restricted time due to the nature and severity of a work-related injury. It is considered the gold standard for data related to workplace safety and can be used by public health in Colorado at different levels to support related grant applications, requests for applications, and requests for proposals.

Information for Colorado employers who are participating

Federal laws require employers that are selected to participate in SOII to do so. Federal law prohibits BLS from sharing the SOII data with OSHA.

The web links below are intended to help you collect OSHA log information, complete your SOII response, find additional information about the survey, and review results from the most recently published survey.

Types of survey participants

In any given year, there are two sets of survey participants.

  1. Employers that have received notice to provide information about occupational injuries and illnesses from the previous calendar year. The statistics determined from the submissions are published in the fall of the year they are collected.
  2. Employers that have been notified that occupational injury and illness information will be collected at the end of the next calendar year.
