ABSTRACT
We adapted the Performance Diagnostic Checklist to analyze the environmental events contributing to safe and at-risk behaviors by employees in organizations. We then used the resulting tool, the Performance Diagnostic Checklist–Safety (PDC-Safety), to identify variables contributing to unsafe equipment usage by 3 members of a landscaping crew at a private university. Based on PDC-Safety results, an intervention consisting of graphic feedback was implemented. The intervention increased safe performance for all participants.
