본 연구의 목적은 안전전담기술인 제도가 안전성과에 미치는 영향을 연구 실적이 부족한 공공공사 건설사업관리현장을 대상으로 연구하였다. 2020년 10월 6일 이후 공공공사를 대상으로 안전전담기술인 제도를 시행하고 있으나 공공공사 발주공사의 사고사망자 수는 여전히 줄어들지 않고 있는 실정으로 시공사 중심의 안전관리, 지도 감독하는 안전전담기술인 제도의 개선방안 제언을 연구 목적으로 하였다. 연구방법의 연구모형은 독립변수 요인으로 제도적 요인, 역량적 요인, 방법적 요인이 안전성과에 영향을 미치는 영향을 알아보기 위한 연구이다. 실증적인 연구를 위해 발주청, 건설사업관리기술인 시공사를 대상으로 172명의 설문조사를 실시하여 불성실 응답자 및 결측지 16명을 제외한 156명의 유효설문을 통계분석에 사용하였으며 통계분석프로그램은 IBM SPSS28을 사용하여 신뢰도 분석, 상관관계 분석, 회귀분석을 실시하였다. 신뢰도 분석 결과 제도적 요인의 Cronbach’s α계수는 0.706, 역량적 요인은 0.915, 방법적 요인은 0.672로 역량적 요인이 가장 높으며 방법적 요인이 낮게 나타났다. 상관관계 분석 결과 안전전담기술인 제도의 제도적 요인과 역량적 요인은 r=.692, p=.000이고 방법적 요인과 역량적 요인은 r=-.223, p=.005로 통계적으로 유의하였다. 하지만 제도적 요인과 방법적 요인은 r=.037, p=.651로 상관관계가 통계적으로 유의하지 않는 것으로 나타났다. 회귀분석 결과 제도적 요인은 표준계수 .420, 유의수준 .000, 역량적 요인은 표준계수 .266, 유의수준 .004, 방법적 요인은 표준계수 .166, 유의수준 .013으로 나타나 안전성과에 정(+)의 영향을 미치는 것으로 나타나 채택되었다. 본 연구를 통해 안전전담기술인 제도는 공공공사 대상 현장 안전성과의 효율성을 높이는 제도임이 실증적 연구 결과로 나타났으며, 안전전담기술인 제도의 지속적 유지와 개선을 통해 사고예방 및 사고비용 절감에 유효한 제도임을 확인하였다. 향후 민간공사 후속연구를 통해 안전전담감리제도가 조기에 도입되어 건설현장의 안전사고 예방과 사고비용 절감에 기여하기를 기대한다. The purpose of this study was to study the impact of the safety technology system on safety performance in public construction project management sites with insufficient research results. Since October 6, 2020, the safety technician system has been implemented for public construction projects, but as the number of accidental deaths in public construction projects is still not decreasing, the safety technician system, which supervises construction company-centered safety management, has been suspended. The purpose of the study was to suggest ways to improve. The research model of the research method is a study to determine the influence of institutional factors, competency factors, and methodological factors as independent variable factors on safety performance. For the empirical study, a survey of 172 people was conducted targeting the ordering office, construction project management technicians, and construction companies. The valid surveys of 156 people, excluding 16 unfaithful respondents and missing answers, were used for statistical analysis. IBM SPSS 28 was used as the statistical analysis program. Reliability analysis, correlation analysis, and regression analysis were conducted. As a result of the reliability analysis, the Cronbach's α coefficient of the institutional factor was 0.706, the competency factor was 0.915, and the method factor was 0.672, showing that the competency factor was the highest and the method factor was the lowest. As a result of the correlation analysis, the institutional factors and competency factors of the safety technician system were statistically significant at r=.692, p=.000, and the methodological factors and competency factors were r=-.223, p=.005. . However, the correlation between institutional factors and methodological factors was r = .037, p = .651, indicating that the correlation was not statistically significant. As a result of the regression analysis, the institutional factors showed a standard coefficient of .420 and a significance level of .000, the competency factors showed a standard coefficient of .266 and a significance level of .004, and the methodological factors showed a standard coefficient of .166 and a significance level of .013. +) was found to have an impact and was adopted. Through this study, empirical research results showed that the safety technician system is a system that improves safety and efficiency at public construction sites, and that it is an effective system for preventing accidents and reducing accident costs through continuous maintenance and improvement of the safety technician system. Confirmed. In the future, we hope that through follow-up research on private construction, a dedicated safety supervision system will be introduced early, contributing to preventing safety accidents and reducing accident costs at construction sites.

The effective evacuation strategy according to the accident scenario is crucial to minimize human casualties in the event of toxic gas leak accidents. In this study, the effect of the direction of a building and the location of an industrial complex on the increase in indoor concentration and outdoor diffusion was examined under the same leakage conditions, and effective evacuation criteria were established. In addition, the guidelines for building directions were suggested when constructing buildings that would mitigate human damage caused by chemical accidents. Three scenarios where buildings faced the front, side, and rear of the leakage direction were investigated through CFD simulations. The results revealed that when the building faced the industrial complex, both indoor and outdoor average gas concentrations increased significantly, reaching up to 120 times higher than the other two orientations. Moreover, the indoor space was filled with toxic gas substances more than twice in the same time due to the rapid increase of indoor concentration rate. In cases where the building's windows were positioned at the front, toxic gas stagnation occurred around the building due to pressure differences and reduced flow velocities. Based on our findings, the implementation of these guidelines will contribute to safeguarding residents by minimizing exposure to toxic gas during chemical accidents.

조대진(Dae Jin Jo),이준원(Joon Won Lee),어원석(Won Souk Eoh),최상찬(Sang Chan Choi),김득환(Deuk Hwan Kim) 안전문화포럼 2023 안전문화연구 Vol.- No.25

본 연구의 목적은 중소규모 사업장의 위험성평가 시행과 안전성과와의 관계를 분석하는 것이다. 2024년 1월부터 5인 이상 사업장의 중대재해처벌법 시행을 앞두고 있으나, 중소규모 사업장의 재해율은 여전히 높은 실정이다. 중소규모 사업장의 안전행동 및 재해예방을 위해서는 자율기반 안전보건관리체계의 핵심이 되는 위험성평가의 역할이 어떠한지 분석해 볼 필요가 있다. 연구방법의 연구모형은 독립변수인 위험성평가 시행여부와 종속변수인 안전 분위기, 안전규정 준수, 안전사고 발생률, 안전 최우선 가치, 위험행동 관리와의 관계를 알아보기 위한 연구이다. 연구대상은 300인 미만 중소규모 사업장의 종사자 211명이었다. 수집된 자료는 IBM SPSS 29 프로그램을 사용하여 빈도분석, 독립표본 t-검정을 사용하여 분석하였다. 연구결과를 보면 중소규모 사업장의 위험성평가 실시 사업장과 미실시 사업장의 독립표본 t-검정 결과 안전 분위기, 안전규정 준수, 안전사고 발생률, 안전 최우선 가치, 위험행동 관리의 수준에 유의미한 차이를 보였다. 본 연구를 통해 위험성평가를 실시한 중소규모 사업장은 미실시한 사업장보다 안전성과 수준이 높은 것을 확인하였다. 이로써 위험성평가는 중소규모 사업장의 안전행동 실행 및 재해예방에 유효한 제도임을 확인하였다. 중소규모 사업장에서 위험성평가 도입을 위하여 사업주의 인식을 제고하고 내부구성원의 위험성평가 수행역량을 확보할 필요가 있음을 확인하였다. 중소규모 사업장의 위험성평가 실태와 안전성과에 대한 후속연구를 통해 위험성평가가 중소규모 사업장에 활성화되어 근로자의 건강과 생명을 보호하는 산재 예방의 효과적인 제도가 되기를 기대한다. The purpose of this study was to conduct a study on the relationship between risk assessment signal and safety in small and medium-sized workplaces. While the Serious Accidents Punishment Act, which will be applied to places of business with five or more employees, will be effected in January 2024, the accident rate in small- and medium-sized businesses is still high. Promoting safety behaviors and preventing accidents in small- and medium-sized businesses require analyzing the role of risk assessment, an integral part of the self-regulatory safety and health management system. In this regard, this study is aimed at examining the relationship between risk assessment and safety performance in small- and medium-sized businesses. The subjects of this study were 211 employees, working at small- and medium-sized businesses that hired less than 300 workers. The collected data were analyzed using the IBM SPSS 29 program, through frequency analysis and independent samples t test. The results revealed significant differences in the domains of safety climate and compliance, accident rates, safety as a top priority, and the level of risk behavior management in small- and medium-sized businesses, based on whether risk assessment was conducted or not. The businesses that conducted risk assessment, demonstrated a higher level of safety performance than those that did not. These findings confirmed that risk assessment is an effective system to improve safety behaviors and prevent accidents at small- and medium-sized businesses. Further research should be conducted on the implementation of risk assessment in small- and medium-sized businesses and their resultant safety performance, to encourage more companies to adopt this practice. This will also facilitate risk assessment to develop into an effective measure for preventing industrial accidents and protecting the health and lives of workers.
