機械の設計段階における危険源同定支援ツールの開発

（支援方法の提案とプロトタイプの概要）

抄録

The implementation of risk assessment (hereafter, “RA”) at the design stage of machinery is essential to prevent the use of machine from being the causes of industrial accidents, however, the diffusion and embeddedness of RA among machine manufacturers in Japan are impeded by the difficulty of “hazard identification” which is regarded as the most important step in the whole RA process. In order to establish an effective support measure for inexperienced design engineers to adequately carry out the hazard identification, this study focuses on the facts that its difficulty is comprised of two aspects and the utilization of requirements stated in the international standards related to safety of machinery can solve both. A hazard identification support tool substantiating the above-mentioned concept is proposed and specification and functions of its prototype under development are described in this paper.
