    • The construction industry has the largest number of injuries compared to other industries. Therefore, reducing accidents and determining construction risks are extremely important. One of the essential steps for construction safety management is hazard identification, in order to prevent fatal and injury accidents on construction sites. Near-miss accidents provide insights into possible accidents and provide a great opportunity to further improve safety margins. It is possibly to significantly improve the safety performance by learning from previous near-miss accidents. Safety management and safety appreciation continue to be the critical factors that influence the unsafe condition, unsafe behavior on construction site. In this research, a structural equation modeling (SEM) is proposed and operated in order to measure the impact mediating variables in the occupational safety to the near-miss on construction site.
    Furthermore, cross-country comparison of occupational safety state in the Taiwanese construction site and Vietnamese construction site was operated by analyzing data collected from different groups of respondents. The analysis provides an evidential basis with the evaluating indicators so that the authority and management board can define the cause effect and implicit cause for the actual situation of occupational safety systems on the construction site.
