Human Factors Analysis and Classification System (HFACS)

The Human Factors Analysis and Classification System (HFACS) is a framework used to identify and understand the human errors and organizational failures that contribute to accidents, especially in industries like aviation. It categorizes these factors into levels such as unsafe acts (errors or violations), preconditions for unsafe acts (like fatigue or communication issues), and organizational influences (like management decisions or resource allocation). By analyzing these layers, HFACS helps organizations identify root causes of accidents, enabling them to implement more effective safety improvements and prevent future incidents.
