When accidents happen, it's important to know why. Even when the reason seems obvious, the real cause may be more complicated. That's where accident investigation comes in. It examines the incident systematically to determine its true root causes. This information can then be used to update policies, procedures or equipment to help make sure a similar accident doesn't occur in the future. Areas covered in the course include accidents and near misses, investigations and root cause analysis, the role of tools and equipment in accidents, the importance of training, the role procedures play in preventing accidents, learning from accidents and more.
