| Abstract |
The aging population of skilled construction workers is increasing. As the proportion of elderly workers with reduced physical and cognitive functions increases compared to young workers, accidents occurring at construction sites will inevitably increase. Additionally, it has been revealed that there are differences in the injured body parts by age group. Therefore, understanding the worker’s age, type of accident, and injury body parts is considered important for effective safety management. In this study, a correspondence analysis method was used to investigate the relationship between the ages of the injured, the injured body parts, and accident types using accident case data that occurred in the construction industry. As a result, it was confirmed that there were differences depending on the category of the variables. By age group, those over 60 years old showed a high correlation with torso injuries, those in their 50s with face and head injuries, and those in their 10s and 20s with foot and ankle injuries. By type of disaster occurrent, falls and falling accidents were highly associated with workers in their 50s and 60s and older, while being struck by objects and cuts were highly associated with workers in their 30s. The results of this study will be helpful in establishing more detailed management strategies and measures when performing safety management in the field. |
