In addition to the Survey of Occupational Injuries and Illnesses (SOII) and Census of Fatal Occupational Injuries (CFOI) products normally produced in any reference year, the U.S. Bureau of Labor Statistics has conducted, in conjunction with other governmental agencies, various "special topic" surveys regarding occupational safety and health-related topics. These special surveys have included the following topics:
The Survey of Respirator Use and Practices was a special survey of U.S. employers regarding the use of respiratory protective devices conducted by BLS for the National Institute for Occupational Safety and Health (NIOSH), Centers for Disease Control and Prevention (CDC). This voluntary survey provided estimates of the number of establishments and employees who used respirators during a 12-month period by type of respirator and type of use. The survey also collected data on the characteristics of the respirator program at the establishment, assessment of medical fitness to wear respirators, characteristics of respirator training at the establishment, usefulness of NIOSH approval labels and respirator manufacturers’ instructions, substances protected against by the use of respirators, and fit testing methods used for respirators. Results from this survey are available at Respirator Use and Practices.
The Survey of Workplace Violence Prevention was another special survey conducted by BLS for NIOSH. This survey studied the maintenance of a safe work environment, including the prevalence of security features, risks facing employees, employer policies and training, and related topics. Data from this survey are available for private industry and state and local government by industry and size of establishment, where size is measured by the number of workers employed. Results from this survey are available at https://www.bls.gov/iif/osh_wpvs.htm.
In 2012, BLS partnered with four states to conduct a series of employer telephone interviews with recent SOII respondents to obtain information on employer injury and illness recordkeeping practices. With its state partners, BLS worked to develop a standardized survey instrument. States contacted enough employers to generalize the results of the survey to all employers in that particular state. Additional information on these employer interviews can be found in the 2016 Monthly Labor Review article “An update on SOII undercount research activities.”
Results from these employer telephone interviews indicated that many respondents lacked Occupational. Safety and Health Administration (OSHA) recordkeeping knowledge. This lack of knowledge may result in an overreporting of less severe injuries and illnesses cases, many that did not need to be recorded or reported per OSHA recordkeeping criteria, combined with an underreporting of more severe injury and illness cases in which the worker missed at least one day away from work. Detailed analysis of the results of these interviews can be found in the 2016 Joint Statistical Meeting article “Identifying patterns in employer reporting errors in the BLS Survey of Occupational Injuries and Illnesses.”
Following the four-state study, BLS partnered with Westat to conduct a nationwide follow-up survey of 2013 SOII respondents regarding their injury and illness recordkeeping practices. Initial results from this study point to similar conclusions, with a lack of respondent knowledge of recordkeeping rules possibly contributing to injury and illness cases going unrecorded and unreported to BLS.
In 2014, BLS began to examine the feasibility of collecting occupational injury and illness data directly from workers to complement the employer-provided data BLS collects via SOII. Research has shown that various filters, or barriers to reporting, can occur when employers collect and report injuries and illnesses. These barriers may be mitigated or avoided by contacting workers directly for this information.
Following some initial exploratory research conducted with Westat, BLS worked with NORC to develop and refine a survey instrument for use in data collection. BLS is using this survey instrument in its work with another contractor, ICF International, Inc, to conduct a pilot test to determine the feasibility of collecting occupational injury and illness data directly from workers. The results of this pilot will inform future BLS decisions regarding the feasibility of a worker survey.
SOII collects data from sampled establishments on OSHA forms 300 and 301. We use the information provided on these forms to generate detailed statistics on the characteristics of cases involving injury or illness. Prior to survey year 2014, BLS exclusively relied on humans to code cases, based on a careful reading and analysis of the case narrative. In 2014, BLS began using computer assisted coding to code a subset of cases. For more information on these efforts and results, please see our automated coding page.
BLS conducted a pilot study in the SOII for reference years 2011 to 2019 to learn about occupational injuries and illnesses that result in days of job transfer or work restriction. The purpose of this study was to compare the case circumstances and worker characteristics of injuries and illnesses that require days away from work to recuperate and those that lead to days of job transfer or restriction only, without time away from work. The SOII historically included only data on the case circumstances and worker characteristics on cases that required at least a day away from work; this study expanded SOII estimates to include the same detail for cases that included days of job transfer or restriction only.
The study began with an initial set of six North American Industry Classification System (NAICS) subsectors collected for data years 2011–13. The study concluded in 2019, and BLS will incorporate biennial DJTR estimates into its SOII production cycle beginning with estimates for the 2021–22 survey years.
