Abstract

The construction safety supervision errors can lead to unsafe behavior; further affect the working conditions of workers and result in accidents at last. The probabilities of data are provided by statistical analysis between the different types of neighborhood-level factors by the independence of the chi-square test. The relationship analysis of the independence between the behavioral factors has been performed in order to find the non-independent factors. Among the Human Factors Analysis and Classification System (HFACS), the impact of the high-level factors on the bottom level is determined. Based on the data, the work path of various factors in the HFACS frame is confirmed and it can be a reference for the development of the preventive measures.

Summary

Introduction

Human Factors Analysis and Classification System (HFACS) can make a preliminary classification of accident which leads by behavioral factors. In the hydraulic engineering construction, one of the purposes of application of HFACS framework is to determine the factors which are relatively important part of the totals in the occurred incidents as quickly as possible. After the adjustment of factors of Standard HFACS framework, it is possible to reflect the actual situation of hydraulic projects more reasonably by strengthening the independence and general. The classification statistics of human factors in accident are described in this study.
