BPA 공장의 메탄올 분리공정에서 HAZOP 평가를 실시하고, 사고 시나리오로부터 화재 및 폭발 사고의 피해범위를 예측하였다. 그 결과, 화재사고의 피해범위는 50 mm 직경의 안전밸브 토출배관 파열에 의한 제트화재에서는 20 m이었고, 설비가 전파되어 플래쉬화재가 발생되는 경우에는 267 m이었다. 또한 개방공간 증기운 폭발사고의 피해범위는 토출배관 파열에서는 22 m이었고, 설비 전파인 경우에는 542 m이었다. 그리고 최악의 누출 시나리오에 대한 안전대책으로는 메탄올 분리컬럼 내부의 이상압력 상승을 감지할 수 있는 압력계를 2 out of 3 voting으로 설비 상부에 설치하여 주공급라인 상에 설치된 컨트롤밸브와 긴급차단밸브를 동시에 차단할 수 있도록 하여야 한다.

Safety is totally established through not only legal regulations and system but the establishment of safety culture. As a foundation of safety culture, safety and health communication is the essential condition. Therefore, in the case of researching safety culture the communication network of a organization is a crucial factor. This study has analysed the structure of occupational safety and health communication between domestic and foreign corporations comparatively by the statistical analysis. The occupational safety and health communication is composed of four sub-dimensions: general communication in working site, using safety information communication, communication with the board of directors, and communication with labor union. The nationality of corporations influences the safety communication significantly except for communication with labor union. Consequently it is possible to infer that the nationality of corporations is a significant factor for safety communication network.

The purpose of this study is to propose measures to increase evacuation safety by calculating the habitable time using a fire and evacuation simulation program for the Room-escape cafe currently in operation, and comparing and analyzing it with the evacuation required time. Assuming a fire due to overheating of electric heaters in use in front of the warehouse, the habitable time was calculated through fire simulation, and the occupant's evacuation time calculated through evacuation simulation according installation of safety facilities, etc. was compared and analyzed with the habitable time. In the case of escape room cafes with safety facilities installed, evacuation safety was satisfied, but in escape room cafes without safety facilities, the evacuation safety was not secure. As a result of analyzing evacuation safety for each scenario based on the ASET analyzed in the fire simulation, it was found that in scenario 1, evacuation safety was secured and everyone successfully evacuated, while in scenario 2, no one succeeded in evacuation. These results can be said to confirm that the installation of safety facilities is very important in business establishments such as escape room cafes, which become enclosed structures when games are started.

One aspect of customer dissatisfaction, safety or more correctly, the lack of product safety has received Particular attention in courts and in legislatures, especially in the developed countries. Therefore, many companies have always regarded safety elements as an essential part of product manufacturing. In this paper, the case study on the product safety of infant cosmetics manufactured by a small-medium enterprise is presented We have focused our study on safety level and control system of product safety, also analyzed the product defects caused by mixing process and all departments. It is found that the product defects( Complaints, Enquiries ) is considerably decreased. These results could be used to deal with a product recall which companies hope never happens to them

Safety management is becoming one of the most hot research issues in Korea. We collected the researcher information in two safety related journals of the journal of the Korea safety management & science and the journal of Korean society of safety. Social network analysis was used to analyse the research relationship among the authors in each journal. The degree centrality, the betweenness centrality, the closeness centrality and the proximity prestige centrality on each researcher were calculated to find out most influenced researcher. Biggest research groups in each journal were introduced by clustering technique.

Loss of human lives and properties including environmental damage due to large scale accidents requires change of our perception to marine safety. IMO is trying to re-establish overall marine safety system through long term plan such as GBS. Along this line, current regulation based safety evaluation is in process of changing into performance based methods, and for this transition, simulation based safety evaluation during design stage considering damage is highly necessary. In this paper, first, damage scenario is developed from IMO regulations and accident case studies. Then an integrated and simulation based safety evaluation prototype system considering both damage stability and structural safety is developed for the use during ship design process.

Safety management cost, $US\$$ one thousand billion has been input to the construction area from 1995 to 2000 but the management quality is still in the developing country level. The above mentioned increase of accident rate are attributed to the generous code regulation, net fit to the sense, varying with time change, but the more fundamental reason of this is no practical construction safety management system, up to now. Hardware-orienting operation for the system could be a main reason of this problem. In this paper, we developed a model for efficient construction safety system. It was found from the case study that the A Study on Introduction Application of Occupational Health & Safety Management System for Construction Industry.

It compared subcontractor with contractor that are wages, the labor hour and labor condition of the work environment back are inferior relative. The subcontractor which basically the contract workers evade the dangerous process or the difficult work, the dirty work back what is called 3D the case which does to keep a business is many. so With life it will be threatened consequent health directly. The possibility where the subcontractor will be exposed to danger work came to be high. Consequently it prevents the subcontract which danger work is insensitive from this research and immediacy of the subcontract workers who is weak hygiene circumstance complement the plan it will be able to secure the immediacy safety&health subcontract workers, substantially to prepare in the hazard subcontract proprietor. Thus, this paper aims at presenting countermeasures to substantially secure safety and health of subcontractors by preventing ill-advised subcontracting of harmful and hazardous operations and imposing partial occupational safety and health responsibility to employers to enhance safety and health environment of subcontractors.

Fire disasters have frequently happened in concrete structures, which resulted in severe structural damages and unsafety. In this case, the method which had evaluated the safety of damaged structures was often unaccepted from most of stakeholders and engineers. The objective of this study is to develope the procedure and method to be able to determine the safety. Numerical simulation was applied to produce the maximum temperature and temperature distribution. Nextly, temperature propagation analysis was performed to plot temperature gradients at each depth and location. The material strength curve versus temperature was applied to determine the safety of concrete structures damaged by fire. The maximum temperature should be calibrated considering real fire records ; magnitude, intensity, situation etc. The results shows that the selected procedure and method was applicable and practical.

A person's body resistance in the waterpark, public bath and similar places is lower than any other places due to effect of water. So low voltage may create a shock hazard for the human body in case of leakage or fault currents from lighting unit etc. We researched the related regulations these are internal standards, NEC, IEC and investigated the actual conditions for the prevention of electrical shock due to lighting units in the waterpark, public bath and similar places. So we could present actual facilities's problems and solutions
