The document proposes an outline for occupational health and safety (OHS) training programs for managers based on two case studies. It identifies 13 key OHS competence areas that should be covered, such as OHS regulations and responsibilities, safety policies and procedures, hazard identification and risk assessment, and safety performance measurement. Feedback from managers who participated was positive, finding the training helped them better understand their OHS duties and tools to promote safety. However, some areas need more emphasis, such as legal responsibilities, motivation, and communication. The proposed outline can be used to structure future OHS training programs for managers.
