This study analyzed the factors affecting the effectiveness of the Chemical Hazard Risk Management (CHARM). A survey was conducted on 104 learners who participated in the Risk Assessment training course at Occupational Safety and Health Training Institute. Through a self-administered questionnaire, the effect of personal characteristics, corporate characteristics, and safety and health level of the company on the effectiveness of chemical risk assessment was investigated. As a result of statistical analysis, the safety and health level of the company had a positive (+) effect on the effectiveness of Chemical Hazard Risk Management(CHARM), but personal characteristics and corporate characteristics had no relation to it. This study can be used as basic data for further research related to chemical risk assessment in workplaces.
One of the important components of a nuclear fuel cycle facility is a hot cell. Hot cells are engineered robust structures and barriers, which are used to handle radioactive materials and to keep workers, public, and the environment safe from radioactive materials. To provide a confinement function for these hot cells, it is necessary to maintain the soundness of the physical structure, but also to maintain the negative pressure inside the hot cell using the operation of the heating, ventilation, and air conditioning (HVAC) systems. The negative pressure inside the hot cells allows air to enter from outside hot cells and limits the leakage of any contaminant or radioactive material within the hot cell to the outside. Thus, the HVAC system is one of the major components for maintaining this negative pressure in the hot cell. However, as the facility ages, all the components of the hot cell HVAC system are also subject to age-related deterioration, which can cause an unexpected failure of some parts. The abnormal operating condition from the failure results in the increase of facility downtime and the decrease in operating efficiency. Although some major parts are considered and constructed in redundancy and diversity aspects, an unexpected failure and abnormal operating condition could result in reduction of public acceptance and reliability to the facility. With the advent of the 4th Industrial Revolution, prognostics and health management (PHM) technology is advancing at a rapid pace. Korea Hydro & Nuclear Power, Siemens, and other companies have already developed technologies to constantly monitor the integrity of power plants and are applying the technology in the form of digital twins for efficiency and safety of their facility operation. The main point of PHM, based on this study, is to monitor changes and variations of soundness and safety of the operation and equipment to analyze current conditions and to ultimately predict the precursors of unexpected failures in advance. Through PHM, it would be possible to establish a maintenance plan before the failure occurs and to perform predictive maintenance rather than corrective maintenance after failures of any component. Therefore, it is of importance to select appropriate diagnostic techniques to monitor and to diagnose the condition of major components using the constant examination and investigation of the PHM technology. In this study, diagnostic techniques are investigated for monitoring of HVAC and discussed for application of PHM into nuclear fuel cycle facilities with hot cells.
Occupational safety and health management expenses in the construction industry are statutory and separately included in the cost statement to prevent occupational accidents and health problems. The expenses are determined by multiplying the standard amount by the rate decided according to construction types and scales. However, the current expense appropriation method does not properly reflect the recent changes in the construction industry such as industry size, industry diversification, and social atmosphere about safety reinforcement. This study surveyed 1579 questionnaires in total and analyzed expense execution rate and proportion of each expense category. The expense execution rate was relative higher in complex construction (e.g., heavy construction = 126%, civil engineering = 125%) and long-period project (equal to or over 48 months construction = 133%) compared to general construction (98~116%) and short-period project (less than 48 months construction = 115%). The proportion of spending expenses was higher in the category of safety manager labor costs (25~52%), safety facility costs (22~40%), and personal protective equipment costs (10~25%). The analysis results of the study can be utilized in revising the standard expense appropriation method by reflecting the current usages of the occupational safety and health management expenses in the construction industry.
The Severe Disaster Punishment Act had recently been established in order to promote safety and health (OSH) management system for severe accident prevention. OSH management system is primarily designed based on risk assessments; however, companies in industries have been experiencing difficulties in hazard identification and selecting proper measures for risk assessments and accident prevention. This study intended to introduce an accident analysis method based on epidemiological model in finding hazard and preventive measures. The accident analysis method employed in this study was proposed by the U.S. Department of Energy. To demonstrate the effectiveness of the accident analysis method, this study applied it to two accident cases occurred in construction and manufacturing industries. The application process and results of this study can be utilized in improving OSH management system and preventing severe accidents.
This study examined the certification effects of safety and health management system (SHMS) on the establishment level of SHMS and accident statistics in construction industry. This study obtained the establishment level of SHMS for 106 construction companies surveyed from our previous study. In addition, three major accident statistics (mortality rate, accidental mortality rate, and injury rate) for the companies were collected from the database in Korean Occupational Safety and Health Agency. The statistical analysis results revealed that the establishment level for SHMS certified companies was significantly higher than those for uncertified or certification preparing companies. Furthermore, SHMS certified companies showed significantly smaller accident statistics compared to uncertified or certification preparing companies. The results of this study support the positive effects of SHMS on reducing major industrial accidents in construction companies.
It was legislated in Korea that the small-sized enterprise with fewer than 50 employees should appoint at least one managing officer in order to improve safety and health of the employees since 2016. Study on the effectiveness of this legislation is hardly found, however. This study tried to evaluate effectiveness of the regulations for appointing the safety and health management officer in small-sized manufacturing companies and make suggestions to improve it. It was done by pairwise comparison between the level of safety and health achievement of 52 companies before and after the legislation. A scorecard system and questionnaires were devised for assessing the level of safety and health achievement and surveying awareness and practice of the regulation in the field. Results from quantitative and qualitative analyses performed in the study confirm that the safety and health achievement score has increased significantly after appointing the managing officer. It is also revealed that the lack of expertise and motivation of the appointed officer would yield pointless outcomes. Recommendations to make it better the effectiveness of the regulation are: to administrate requirements more strictly to be appointed as a safety and health management officer, to revise the curriculum to train the expertise of the appointed officers, and to expand financial support of the government to settle the safety and health management system.
The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization’s safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.
정부와 안전보건공단에서는 건설현장의 안전사고를 줄이기 위하여 감독․점검, 기술지도, 재정지원 등의 산업재해예방 활동을 지속적으로 수행하여 왔다. 하지만, 전체 산업의 사고사망만인율과 재해율이 전반적으로 감소 추세에 있는 반면에, 건설업의 사고사망만인율 및 재해율은 2014년 이후 오히려 증가 추세에 있다. 특히, 2016년 재해통계를 기준으로 전체 건설업 재해자의 약 70%가 공사금액 20억 미만의 소규모 건설현장에서 발생하였다. 이러한 소규모 건설현장의 재해를 줄이기 위해서는 현재의 산업안전보건법 상의 소규모 건설현장 산업안전보건관리체제와 고용노동부 및 안전보건공단에서 수행하고 있는 소규모 건설현장재해예방 사업에 대한 실효성을 파악하고 개선할 필요가 있다. 현 산업안전보건관리체제에서는 건축공사 기준으로 120억 이상인 공사인 경우 안전관리자를 의무 선임하도록 되어 있으며 3억에서 120억 미만 공사의 경우 재해예방지도기관의 기술지도를 받도록 되어 있다. 또한, 안전보건공단에서는 민간위탁기관을 지정하여 3억 미만 건설공사의 안전관리를 지원하고 있으며, 클린사업장 조성지원사업을 통해 20억 미만 소규모 건설현장의 추락재해예방을 위해 시스템 비계, 사다리형 작업발판 및 안전방망 등의 설치 비용을 지원하고 있다. 본 연구에서는 공사금액별 재해통계 및 안전관리자 선임관련 제도를 분석하여 안전관리자 선임 대상을 현행 건축공사 120억 이상인 공사에서 단계적으로 50억까지 확대할 것을 제안한다. 설문조사와 전문가 의견을 수렴하여 재해예방지도기관의 기술지도 영역을 조정하고 실효성을 강화하기 위한 방안을 수립하고, 클린사업장 조성지원사업의 사업 확대 요구 및 개선사항을 도출한다.

The occupational health and safety accidents were continuously increased during handling, usage and manufacturing the chemical materials according to increase of small and medium sized enterprises in domestic industries. These accidents mainly resulted from insufficient occupational health and safety management and deteriorative facilities and focused on corresponding operation to minimize the damage of accidents after occurrence. But, it was required that we grasped the occurrence causes of occupational health and safety risk in handling, usage and manufacturing the chemical materials and develop the adequate corresponding operation and system according to the possible occurrence of occupational health and safety risk. This study deals with the development of risk assessment model to derive the risk and important risk of occupational health and safety and then help to construct the self-controlled occupational health and safety system for small and medium sized enterprises handling the chemical materials.
This study is aimed to investigate the occupational safety and health management of contractor company in the car industry. The questionnaire survey was conducted on the suppliers and contractors of car industry. Data were collected from 10 contractor companies and their 291 contractor companies(each outside and inside company). From the survey result, it was found that the level of all-round safety and health management is above the average. To strengthen the relationship for safety and health management, it is needed that the supplier company employ the person in exclusive charge to support contractor. Also it is needed the active support of the contractor company and needed that the supplier company employ the person in exclusive charge to support contractor. Finally, Many of the problems associated with the safety and health management by strengthening contractor company responsibility will have to be solved simultaneously.
OSHMS(Occupational Safety and Health Management System) is able to define as a typical convergence of all kinds of activities and elements that support maintaining safety at workplace and protecting employee's health. In particular, fundamental function of OSHMS is preventing diverse hazards at workplace through high level of regulation compliance. Furthermore, insuring safety in workplace, protecting employee's health and increasing effectiveness in manufacture are OSHMS's additional functions. Based on the division of manufacture in 2009 Survey on Current Status of Occupational Health & Safety data, the study analyses certain relation between OSHMS and level of regulation compliance. The main finding is that most activities and elements which formed by OSHMS are being affected by regulation clauses.
Occupational illness analyses are used to identify common factors contributing to occupational illness and to give recommendations for illness prevention. We discuss safety and health management policies based on the present status of MSDS(Musculoskeletal Disorders) characteristics and the actual safety and health problems. These results can be used to develop more effective occupational safety and health management policies for the prevention of MSDS.
This article is concerned with various aspects of establishing the global standard for occupational safety and health management system (OHSMS). The notion, main features, and brief history of the OHSMS are presented. The OHSAS 18000, its assets and liabilities, are reviewed as a prototype of the global standard. It is also addressed the possibility of combining ISO 9000(quality management system), 14000(environmental management system) and the OHSMS into the integrated management system (IMS) as a whole. The concepts of internal and external customers are presented to explain why the environment, safety and health should be incorporated into the notion of total quality 'Participation of the members' and 'standardization of the 4Ms (Man, Machine, Materials and Method)'are emphasized as the major enablers of the IMS. Finally, the industrial, academic and governmental roles are discussed for developing the IMS and setting it down into the Korean industries.
