Abstract: This article presents an association rule-generation algorithm for mining industrial safety data. Examples of accident data are information about injured workers (e.g., age, gender, work experience), date and time of accidents, and severity level of accidents. The proposed algorithm implements the elementary set concept to generate useful relationships between accidents and worker-related attributes and severity of accidents. The relationships are presented as IF-THEN association rules, where the IF statement(s) include a set of accident condition attributes and the THEN statement(s) include attributes that represent a decision outcome (i.e., accident severity). After the rules are generated, the algorithm applies a user-specified filter and a statistical significance test to identify important rules. The rules that pass the filter and the significance test are then reported in the solution. A case study of using the algorithm to mine real safety data obtained from a selected industry is presented, along with examples of reported rules and their interpretations.
