이동식 크레인 사망재해의 인지공학적 대안

Abstract

Abstract According to the statistics, occupational fatal injuries by m obile cranes were about 12 per year in whole industrial. Mobile cranes are widely used in various part s of industries to improve the efficiency of the work. However considerable number of fatal injuries happ en each year during the operation of the machines. In this study, the current regulations to be adeq uate in industrial site have to be renew in order to prevent the fatal injuries by mobile cranes. Fatal injury analyses were conducted with several accident ca ses by the mobile cranes. For each accident, the causes of the injuries were examined and proper s afety measures were proposed. In this study, the mobile crane showed a high fatality rate in industrial accidents and no detailed cause analysis of fatal accidents was conducted in terms of unsafe ac ts or conditions. This study proposed a revision of the standard guideline as an accident prevention me asures through in-depth analysis of fatal accidents. First, among the mainly five machines caused the accidents, m obile crane was higher for the second showed 0.6% for number of fatalities compared to number of mobi l cranes and for the third showed 11% for number of fatalities compared to number of injuries. Se cond, main cause of cognitive engineering agenda was visibility, responsibility, affordance. As the measures to prevent accidents before starting operation, alternative revision for the fool pr oof including visibility, responsibility, affordance etc. for the fool proof measures was proposed. Third , alternative revision as cognitive accident prevention for the fail safe measures was proposed.Key words : mobile crane, human error, visibility, compatibilit y, fool proof, fail safe.
