국내 산업재해는 점진적으로 감소하고 있음에도 불구하고 건설업에서의 사망자는 전체 산업의 49.9%를 차지하고 있으며, 그 중 추락사고 사망자는 59.7%의 높은 비중을 차지하고 있다. 이에 따라 정부차원에서 건설업의 추락사고를 예방하기 위한 다양한 안전 활동 및 정책을 추진하고 있으나 그 효과는 미비한 실정이다. 반면 미국, 일본, 영국, 싱가포르 등 해외 선진국의 경우 각국의 상황에 적합한 안전 활동, 규제 및 정책 등을 펼친 결과, 국내보다 산업재해 발생율이 저조했다. 따라서 본 연구의 목적은 국내 산업안전보건법과 해외 선진국의 법령을 추락재해에 밀접한 영향을 미치는 기인물별로 비교·분석하여 국내 실정에 맞는 개선방안을 제시하는 것이다. 비교 분석 결과, 본 연구에서는 국내 건설현장의 추락재해 저감을 위한 개선방안으로 1)추락 높이에 대한 기준 개선 2)안전난간 상부난간대 높이의 개선 3)수평안전대 부착설비 연구 및 지침의 개정 등의 개선방안을 제시하였다. 향후 본 연구는 해외 선진국의 사례분석을 위한 기초자료로 활용될 것이다.

최근 건설구조물의 대형화, 고층화로 인해 고소작업이 증가하며 떨어짐 사고(이하 사고)가 증가하고 있다. 근로자의 불안전한 행동이 산업재해의 주요 원인으로 밝혀지며, 불안전한 행동 예측 및 관리의 필요성이 제기되었다. 이 연구는 건설 현장에서 근로자의 불안전한 행동과 사고의 관계를 확률로 제시하여 불안전한 행동의 개선 효과를 산출하는 것을 목적으로 수행되었다. 재해사례를 분석하여 근로자의 불안전한 행동을 도출하고, 설문조사를 통하여 불안전한 행동으로 인한 사고의 발생 확률(이하 사고 확률)을 산출하였다. 사건수 분석 기법(Event Tree Analysis; ETA)을 활용하여 불안전한 행동의 조합에 따른 최종 사고 확률과 개선 효과를 확인하였다. 불안전한 행동별 사고 확률은 음주 후 작업 수행(95.41%)이 가장 높았고, 장비 및 기계 활용(65.70%)이 가장 낮았다. 불안전한 행동의 조합에 따른 사고 확률은 불안전한 행동을 모두 수행한 경우(13.23%)가 가장 높았고, 불안전한 행동을 수행하지 않은 경우(0.00%)가 가장 낮았다.

Among the industrial disasters caused by drop, ladder related drop disasters are occurred the mostly. The victims are occurred continuously. This study analyzed current situation of industrial disasters for recent 10 years(2005~2014) and compared analyzed statistics of death disasters of ladder by workplace scale, age, occupation, employment type, working content, scarred area, etc. in detail. This study suggested direction of safety standard modification for ladder that is an original cause material of many drops, direction of safety training strengthening of small-scaled workplace, and safety model based on disaster statistics and should contribute to reduction of disaster rate for ladder working.

The safety concern of slipping on floors in South Korea has come to the fore as a social problem, but the occurrence of such accidents has not decreased. Slip and fall accidents have several causes, but they are especially common when there is soapy water on the floor during a shower or a bath. Despite this situation, it can be said that there is a lack of standards on surface contamination materials used in floor slip resistance testing. Therefore, in this study, we conducted a survey to identify the components and quantity of soapy water that actually results from a user taking a shower, and the standardization of contamination materials. Based on the results of this experiment, we provide a surface contamination material that can replace the soapy water used in floor slip resistance testing.

The construction companies are facing potential EHS(Environment, Health & Safety) of major accidents to cause casualties or a financial loss and increasing social responsibility. So, they have to voluntarily accomplish the EHS management system rather than passively with regard to EHS regulation. In this study, the integrated EHS management system is developed based on cloud computing, and construction companies are to materialize self-regulation EHS process of construction workplace and to standardize the total EHS business process using the developed system. The proposed system also provides risk analysis, education/control and continuous improvement for EHS tasks and users can easily access the system on the web at a low price through cloud computing service. Eventually, the integrated system contributes to the managerial improvement by minimizing economic and physical loss caused by construction accidents.

Although gangform has good workability due to the integration of outer wall forms and working platforms, 22 workers were died from 21 gangform related accidents during 2012 to 2016. Quantitative risk assessment is required for evident based prevention measure selection. In this study, based on 52 accident data from 2004 to the first half of 2019, FTA is conducted for probabilities of direct causes and their contribution to accidents. Three stages are considered; gangform installation, dismantling and lifting, and using. The effectiveness of countermeasures is evaluated through minimum cut set, RAW and RRW. Complete assembly of gangform on the ground level, detailed planning, and fall prevention device are suggested as prevention measures for installation, dismantling and lifting, and using stages, respectively.

Although the disaster rate of the industry as a whole is on a downward trend, the disaster rate of the construction industry is on an ongoing trend. Therefore, in this study, we analyzed safety accident statistical data of the construction site over the past three years. As a result of the analysis, the incidence of disasters at small construction sites was very high. And the proportion of disaster occurred for workers who worked in less than 6 months even roughly 92.6%. In addition, as a result of analyzing the form of disaster occurrence, the crash was 34.1% and the fall was 15.1%. The analysis results of these construction safety accidents are to provide as a basic material for developing a policy that can prevent safety accidents and a safety accident prediction model.

The purpose of this study is to analyze the vocabulary related to safety accidents based on the reports recorded on the violation of safety rules at the construction sites. We used Word2Vec and Topic Model as natural language processing techniques to analyze the safety accidents presented in the reports of the large enterprise. The words that appeared based on the occupational accident types such as the fall, falling objects, and others were derived and visualized. We derive the frequency and similarity of the words and topics of the accident that occur at the construction site. In future studies, we will be able to proceed with the generation of texts from pictures based on images and this reports.

Construction is one of the most hazardous industries due to its unique nature. Recent occurrences of highly publicised and criticized construction site accidents have highlighted the immediate need for the construction industry to address safety hazards. Safety used to be addressed as an isolated issue in the past, but the problem of safety is an emergent property of a system. In general, it seems that both industrial practitioners and government officials have tended to address safety by focusing on technical aspects and looking for immediate causes of accidents after they have taken place. The objective of this paper is to examine issues and critical factors that affect the safety standards from a holistic point of view. The job of making worksites safe should not just fall squarely on the contractors but should be shared by all parties in the value chain of construction activities.

Even though the Al. form system, which was developed to replace the Euro-form, has been used as the slab lower formwork for almost all concrete structures based on the light weight and high conversion rate, the low-noise Drop method has been developed and used in order to overcome the limitations of the Al. Form system such as noise pollution and safety accidents caused by free fall during the demolding. However, as the low-noise drop method is still insufficient, Safety Full Drop Al. Form method is expected to be in the spotlight in the construction market based on its excellent advantages compared to the developed methods. In addition, we plan to conduct research to further contribute to securing the quality of the overall structure through continuous improvement and supplementation by introducing an automation system to the very construction method.
