The Human Factors Analysis and Classification System (HFACS) categories are derived from the framework established by the Reason's Swiss Cheese Model of accident causation, which emphasizes the role of human error and organizational influences in accidents. HFACS categorizes human errors into four main levels: Unsafe Acts, Preconditions for Unsafe Acts, Unsafe Supervision, and Organizational Influences. These categories were developed through extensive analysis of aviation accidents and serve to systematically identify contributing factors to safety incidents. HFACS is widely used in various industries to enhance safety and reduce the likelihood of accidents.

Where do the categories in the HFACS come from?
The Human Factors Analysis and Classification System (HFACS) is derived from a combination of human factors literature and aviation accident investigations. It categorizes human error into different levels, including organizational, supervisory, preconditions for unsafe acts, and unsafe acts themselves. The framework was developed to provide a comprehensive understanding of the underlying factors contributing to accidents, particularly in aviation, but has since been adapted for other industries. Its categories are intended to help identify and mitigate human error in complex systems.

Is not an unsafe precondition according to HFACS?
In the Human Factors Analysis and Classification System (HFACS), an unsafe precondition refers to factors that could lead to accidents or incidents but are not directly related to human error. Examples include environmental conditions, equipment failure, or organizational factors that create a hazardous situation. Therefore, anything that does not contribute to these unsafe conditions—such as proper training, effective communication, or adequate resources—would not be classified as an unsafe precondition. Ultimately, HFACS aims to identify the root causes of accidents to improve safety and performance.
