Development of a quantification model for human accidents on construction sites in South Korea

The accident rate in the Korean construction industry is rapidly increasing each year. In particular, the mortality rate from human accidents in construction is very high compared to that of other industries. This indicates that the safety activities carried out at the national level have not been effective in reducing the accident rate. To resolve these problems, the risk factors for human accidents should not only be forecasted in advance, but should also be controlled, monitored, and managed from the commencement to the completion of construction projects. However, most studies on this topic have only listed the importance of risks based on the frequency of safety accidents rather than providing a quantitative analysis.Therefore, it is necessary to develop a model that can analyze and quantify the pattern of human accident risks. The purpose of this study is to develop a quantification model for human accidents in South Korean construction sites. To this end, insurance claim payout data were collected and analyzed to develop a risk quantification model using a Monte Carlo simulation. The results will be used as base data to develop a construction site safety management checklist and human accident prediction model

Worker safety perception analysis of South Korean construction sites

Purpose. The aim of this article was to measure the safety perception level of workers on a South Korean construction site and investigate safety problems using the Nordic occupational safety climate questionnaire (NOSACQ-50). Methods. The survey was carried out via the NOSACQ-50 with 175 workers from five South Korean construction companies to evaluate their perception level. The results were then compared with the NOSACQ-50 criteria. Results. The safety perception of this South Korean construction site is high when compared with the NOSACQ-50 criteria. This high level was especially pronounced for the seventh dimension of the efficacy of the safety system, which showed the highest level among all dimensions. In addition, we suggested improvements and interventions to sustain a safety climate amongst workgroups. Conclusions. This study confirms that the seventh dimension showed the highest safety perception amongst all dimensions in South Korea. In the future, these findings can be utilized to develop an evaluation tool for the safety climate of the construction industry in South Korea
