Abstract

Unsafe behavior contributes to 90% of the causes of construction accidents. To prevent construction accidents, studies on existing unsafe behaviors have been regularly conducted. However, existing studies generally tend to average the survey results and conduct analyses thereon, and such a method cannot consider the potential risk as regards people’s anxiety about a certain unsafe behavior. Thus, this research suggests an Importance-Dangerousness Analysis (IDA) technique so that potential risks due to unsafe behaviors of laborers working in the construction sector could be evaluated. In order to verify the applicability of the suggested technique, an actual survey was conducted, and the results of Importance-Performance Analysis (IPA) and IDA were compared with each other. It was found that, unlike IPA, unsafe behaviors that could pose potential risks were confirmed by IDA. Further, unsafe behaviors in the construction sector that should be urgently addressed were also studied. Finally, the IDA suggested in this research could contribute to effective construction safety management on-site by supporting the decisions of the safety manager based on the unsafe behavior analysis of construction laborers.

Highlights

Construction industry is highly accident-prone owing to the typical job characteristics such as outdoor production, workplace height, and high dependency on manpower

Summary

Introduction

Construction industry is highly accident-prone owing to the typical job characteristics such as outdoor production, workplace height, and high dependency on manpower. The death toll in industrial accidents in the construction sector was 557, which accounted for 38.8% of the total death toll of 1,435 in the entire industry. Various studies are being conducted to evaluate the background factors of unsafe behavior of construction field laborers, structural analysis of the influencing factors of safe behavior, and so forth. Like in most of the survey analysis, the average value has a significant implication in such methods, and, this process is inherently inadequate in evaluating the potential risks of unsafe behavior. In this study, a method for analyzing the potential risk of unsafe behaviors of construction laborers is to be suggested.
