Abstract

In this study, the effectiveness of two kinds of existing safety activity for inexperienced workers was investigated experimentally from the view point of performance of risk perception and from self-evaluation of risk perception. Thirty-four workers participated in the experiment and were divided into a tablet-based safety activity group and a self-directed safety activity group. They took a risk-prediction test and evaluated their usual risk perception at work before and after each safety activity. Results indicated that in a tablet-based safety activity group, performance of the risk-prediction test increased and self-evaluation of risk perception became safer after the safety activity, suggesting that such activity may improve worker safety. In a self-directed safety activity group, while performance of the risk-prediction test didn’t increase, the confidence in answering the risk-prediction test did, suggesting that this group may have falsely thought that they could perceive hazards that they really couldn’t. Although a safety activity can be changed to the situation of each work site, these results showed that some kind of safety activity may have a negative influence for inexperienced workers in a dangerous way Therefore, contents of a safety activity should be selected after considering testers’experience.
