Safety Risk Assessment of Prefabricated Buildings Hoisting Construction: Based on IHFACS-ISAM-BN

Prefabricated buildings that are more environmentally friendly have been vigorously promoted by the Chinese government because of reduced waste and carbon emissions during construction process. Most processes prefabricated completed in component factory, but safety risks hoisting process cannot be ignored. In this paper, initial framework a Bayesian Network (BN) is obtained from combination improved Human Factors Analysis Classification System Model (HFACS) BN. The similarity aggregation method (SAM) used to calculate prior probability BN, which can better summarize deal with fuzzy judgment experts on risk accidents. SAM consider both weight relative consistency their opinions, great significance for improving reliability BN inputted data. This paper uses project Sanya, Hainan Province, verify validity model. results show calculation model basically consistent actual situation. relatively low, premise unsafe behaviors supervision key factors project. addition maintaining good conditions workers’ healthy states, it also necessary carefully check performance tower cranes equipment such as spreaders. During operation crane, workers should avoid walking or staying within range.
