Abstract (Summary)

The Occupational Safety and Health Administration (OSHA) asserts injury and illness rates are lower in firms who implement effective Occupational Health and Safety Management Systems (OHSMS). However, no study has been conducted on a large national OHSMS database to support this assertion. Utilizing nationwide data (1,741 records from 45 states and federal territories for federal fiscal years 2015, 2016, and 2017) generated during OSHA Consultation’s program assessments, this study examined the impact of OHSMS programming on occupational safety and health outcomes in micro (<5 workers on-site) and small enterprises (<250 workers on-site, and <500 workers corporate-wide). Safety and health performance data and associated OSHA total recordable case (TRC) and days away, restricted, and transfer case (DART) incident rates were collected by trained OSHA consultants across the United States. OHSMS data were collected using OSHA’s “Safety and Health Program Assessment Worksheet” (Revised Form 33).

Results of this study reported statistically significant (p < .05) mild negative correlations for 57 of the 58 attributes on Revised Form 33. “Planning and Evaluation” (ρ = -.183, p < .01) and “Administration and Supervision” (ρ = -.180, p < .01) had the strongest negative correlation to TRC rates of Revised Form 33’s seven subcomponents, while “Administration and Supervision” (ρ = -.222, p < .01) and “Management Leadership” (ρ = -.204, p < .01) had the strongest negative correlation to DART rates of the seven subcomponents. Certain regression modeling determined less than 8% of variability in reported injury and illness rates could be predicted. There were nine statistically significant subsets of Revised Form 33 attributes OSHA Consultation programs can use when conducting limited service, non-comprehensive visits.

This study is both unique and significant because no large-scale nationwide study has been conducted analyzing OSHA’s Revised Form 33 data coupled with OSHA recordable injury data. This is important as scholarly literature has struggled to scientifically connect high performing OHSMS with improved safety and health performance to date.
