This study develops a model that examines the relationship between safety leadership, safety knowledge, and safety culture on safety performance by moderating the personality traits of workers. This model is further evaluated to determine whether the latent variables of leadership attitudes about safety, the knowledge they have of safety by workers, the formed safety culture and personality as defined in the safety theory and personality traits theory, can significantly influence safety performance. The research model was empirically tested using data collected from 70 workers. To know the relationship between latent variables and interactions with moderation variables, this study uses the structural equation model (SEM) method. The results show that all variables have a significant relationship to safety performance, but personality traits cannot moderate the relationship between all independent variables on safety performance.
