Abstract

The workers’ unsafe action is a major cause of the work accident on building construction industry. Personal factors are variables that needed to be examined in the study of unsafe action due to its strong influence on personal behavior. We established influence between personal factors and unsafe acts using structural equation modeling (SEM). The study was observational research with cross sectional design. A questionnaire was administered to building construction worker, and the following results were obtained. First, worker’s knowledge affected unsafe action by means of perceived benefit, and safety attitude. Second, worker’s perceived risk directly affected worker’s unsafe action. These findings can be used as preliminary data to develop safety programs specifically for safety communication between subcontractor, and workers.
