Early intervention mechanism for preventing electrocution in constructionengineering

摘要

The aim of this study is to establish an effective early intervention mechanism forconstruction engineering to prevent electrocution while improving labor safety andreducing the casualty risk. This study used narrative text analysis and the Haddon Matrixfor data collection, and analyzed the causes from the 113 electrocution deaths among inthe construction industry, the exhaustive chi-square automatic interaction detectoralgorithm was employed the segmentation of the correlations. Based on the theory ofinventive problem solving, through IDEF0 (ICAM DEFinition) for function modeling wasdesigned the early intervention mechanism. This study revealed the operating featuresrelated to electric shock hazards. Early intervention was introduced to reduce therelevant risks and establish safety mechanisms. The first contribution of this study isthe determination of hazard correlations between operating features and conductive media,and entry point for the prevention of electrocutions. The second contribution is thesuggestion of the establishment of inspection stations for electric tools, therebyensuring that the portable power tools are safe. The final contribution is the jointapplication of TRIZ (Teoriya Resheniya Izobreatatelskikh Zadatch) and IDEF0, whichestablishing the pre-entry testing, strengthening safety mechanisms.
