As a part of an organization’s overall risk management efforts, root cause analysis (RCA) is a valuable approach for assessing Occupational Health and Safety (OHS) risks. Whether in a healthcare setting, on a construction site, in a manufacturing facility, at a service provider or elsewhere, RCA can be used to reveal underlying factors contributing to workplace incidents, identify preventive actions, support data-driven decision making, and facilitate continuous improvement in an organization’s OHS programs. Learners in this online course will be introduced to basic concepts in RCA, its uses in the OHS setting, and a set of basic, yet effective, tools for conducting RCA.
