Study on the Possibility of Measurement of Individual Risk Perception

概要 （図表や脚注は「報告書全文」に掲載しております）

危険感受性測定可能性を検討すべく，3つの映像を用い，危険源の指摘数ならびに，指摘内容の深さ・正確さを指標として，実験的検討を行った。その結果，知識・経験は危険感受性に影響を及ぼすこと，そして，作業状況に特化しない，生来的な危険感受性を計測できる可能性が見いだせた。危険感受性測定方法を作成するにあたり，今後の課題が考察された。

概要 （英文）

In industry,diminished workers' risk perception is concerned about because of retirement of postwar baby-boom generation and decreasing labor accident by improvement in facilities. Although hazard prediction activity is carried out for improvement of workers'risk perception in sites, it is get into a rut not to estimate the effects of the activity. Then the purpose of study is to examine the possibility of measuring and estimating individual inherent risk perception not depending on the experiences and knowledge, and to confirm the effects of the experiences and knowledge on one's risk perception. Eleven subjects were requested to detect the hazards and to estimate the results and the extents of damage in the three films that were included in some hazards. The rate of hazards detection and the accuracies of 5 categories, that were hazards, near-miss situation, damage of human, damage of objects or facilities and coping, were calculated.The experience of feeding had effects on the rate of hazards detection and some of the accuracies at the film of feeding at the GS. Also, all of indices were significantly lower at the firm of overhauling a valve than the firm of working at an office. These results showed that the experiences and knowledge were affected on one's risk perception. Meanwhile, the similarity of the tendency to the rate of hazards detection and the accuracies between 2 firms except for the firm of feeding was found by means of the ordinal correlation. The result showed that it will be able to measure the individual inherent risk perception from the number of hazards detection and the depth of the context. The future issues are discussed for developing the method to evaluate the risk perception.
