ANALYZING CAUSES OF ACCIDENT AT WORK BY USING HFACS: HUMAN FACTORS ANALYSIS AND CLASSIFICATION SYSTEM
Keywords:
Accident causations, Latent failures, Active failures, HFACS techniqueAbstract
Different factors can cause an accident at work such as individual, organizational and environmental factors. Understanding root causes can prevent the occurrence of accidents at work. This article aimed to describe a method to analyze causes of accident at work, namely Human Factors Analysis and Classification System (HFACS). HFACS technique has been accepted widely to be a useful method for analyzing accidents at work in many industries. This technique was originally developed for analyzing human performance and human error in the high-risk industries such as military and aviation. Analyzing causes of accident by using HFACS considers two main factors including I: latent conditions such as Organizational Influences, Unsafe Supervision and Preconditions for Unsafe Acts; and II: active failures such as unsafe act. All factors are subsequently categorized into four levels. The HAFACS’ results can able to know causes of accident holistically for seeking some appropriate ways to manage and prevent them.
