The Systematic Human Factors Analysis and Classification System (SHFACS)

The Systematic Human Factors Analysis and Classification System (SHFACS) is a structured method used to identify and analyze human errors that contribute to accidents or incidents. It categorizes how mistakes happen—whether through decision errors, slips, or lapses—and examines the context, environment, and actions involved. By systematically classifying these factors, SHFACS helps organizations understand underlying human contributions to incidents, enabling them to improve safety protocols, training, and design to prevent future errors. It’s a tool for thorough, consistent analysis aimed at enhancing overall safety performance.
