This 24-hour EM 385-1-1 Refresher Course is designed for workers, supervisors, and safety professionals who need a more comprehensive update on the U.S. Army Corps of Engineers (USACE) and NAVFAC safety requirements. It goes beyond the standard 8-hour refresher by offering in-depth review and practical guidance across high-risk areas such as fall protection, confined space entry, PPE, electrical safety, excavation, hazard communication, job hazard analysis (JHA), and accident prevention planning. The course emphasizes current EM 385-1-1 updates, real-world safety practices, and field application of standards to support full compliance on military and federal construction sites. Learners will complete knowledge checks, final assessments, and receive a certificate of completion upon passing. Ideal for SSHOs, QC Managers, Site Supers, and contractors requiring an extended refresher or mid-point training between initial 40-hour certification and field work.
