碩士 === 高雄醫學大學 === 職業安全衛生研究所 === 97 === The goal of this study is to discover the construction and factors of human reliability and un-safety behaviors in a chemical factory, the operation of tanker with allyl alcohol and the operation of filling vinyl acetate were investigated. The methods of this study contain three parts. Part one is using questionnaire to survey the error self-knowledge, Part two is using error analysis to define errors in the quantity and quality. Part three is investigating the work activity to evaluate the error mode. For the operation of tanker with Allyl Alcohol and the operation of filling Vinyl Acetate, action errors has occupied a major part (59/74), Then based on the Ramussen principle of motion levels of prescription, for the operation of tanker with Allyl Alcohol and the operation of pouring Vinyl Acetate, The major part are skill-based (34/74) and the ruled-based (33/74). About the operation of tanker, the highest error rate was 0.0015 and the actions are wearing protective equipment and puting the safe lock to hook in the railing. About the operation of filling, the highest error rate was 0.04 and the action is removing the filling arm to another tank. This result help to establish the error model to improve the operation procedure or the system and to prevent these errors from happening again in chemical factories.
