Bureau of Labor Statistics/SOII

The Division of Safety & Hygiene research and statistics department partners with the BLS to conduct the annual SOII, the largest survey on the number and frequency of nonfatal workplace injuries and illnesses in the U.S.

Here you'll find information to help you complete and submit your response to the survey, and data from previous years for the State of Ohio. 

Each year more than 4,500 private and public employers are selected as a representative sample of Ohio's employers to participate in the survey. When you participate, you help us obtain a reliable representation of work-related injuries and illnesses in Ohio's workplaces. Selected employers receive notice one year prior to the survey collection to ensure they have established recordkeeping procedures for capturing the necessary data. For most employers this is the mandatory Occupational Safety and Health Administration (OSHA) recordkeeping logs. 


The purpose of the survey is to provide annual information to the public on the number and frequency of nonfatal workplace injuries and illnesses. It's the largest survey of its kind in the United States. The data can be used to develop workplace safety and health standards; assist in controlling work hazards; and provide information to employers and consultants for developing workplace training. 

"The confidential BLS survey is designed to be simple to complete and yet provide a wealth of information to assist you in promoting a safer and healthier workplace. Response to this survey as developed as part of the OSHA Act of 1970 (PL 91-596) is mandatory." BLS could impose a fine of $10,000 and/or six months in jail for noncompliance.
