Background & Objectives: International radiation protection committee recognized the importance of radiation protection from medical practices because the exposure to the radiation in medical practice is higher than any other exposure. The factors on knowledge, attitude and practice of radiation safety of the medical workers engaged in radiation were analyzed in order to improve radiation safety technology. Method: Questionnaires were used for 1200 radiation workers in medical institution from July 23 through September 4 and collected for analysis. Results: Different level of safety measures were practiced by age, marital status, career, and medical facility. The difference was statistically significant. Higher levels of safety measures were practiced in the age group of 50s and married persons. The workers who have more than 20 years experience have higher level of safety measures. The workers of health centers have higher level of safety measures to compare with other workers. The factors which give more concerns on safety practice were self efficacy, practice and knowledge in order. Conclusion: Safety conscious operators should get additional education program to maintain higher level of safety. The operators who do not have much safety concern should be intensive training program for self efficacy and safety.

Objectives: This study was designed to examine the effect of risk assessment on employee safety behavior in manufacturing workplaces. In addition, this study attempted to explore factors related to the occupational safety and health system in the workplace affect the risk assessment of manufacturing sites. Methods: This research is a cross-sectional study using the Korea Occupational Safety and Health Agency's 2018 Occupational Safety and Health data. The sample for study is 1,967 manufacturing workplaces. Data were analyzed using descriptive statistics, t-test, ANOVA, chi-square test, and hierarchical multiple regression analysis using SPSS (ver.25.0). Results: As a result of the multiple hierarchical regression analysis, it was found that risk assessment had an effect on employee safety behavior (t=4.435, p=<.001). Furthermore, the size of the workplace affected employee safety behavior (t=2.494, p=<.001). In addition, the presence of safety and health management organizations affected employee safety behavior (t=4.301, p=<.001). The factors of the safety and health organization (𝑥²=35.245, p=<.001), the occupational safety and health committee (𝑥²=149.440, p=<.001), and the supervisor (𝑥²=16.472, p=<.001) were identified as factors that increased the possibility of risk assessment in the manufacturing workplaces. Conclusions: In this study, it was found that risk assessment is a factor that increases the level of workers' safety behavior in manufacturing workplaces. Therefore, it is necessary to provide institutional support for activating risk assessment at manufacturing workplaces.

Objectives: The utility of the system was analyzed by applying the smart safety technology system to the aging pipe rehabilitation facility construction classified as a confined space. Methods: Smart safety management system was applied to a site where the aging pipe rehabilitation work was in progress. The working environment was measured for 25 days, and the toxic gas saturation was analyzed according to the working time and working place. Results: Based on the measured results, two characteristic environmental changes in the confined space were confirmed. First, when working inside an aging pipe, the tendency of carbon dioxide saturation increases with working time and the number of workers. Second, oxygen decreases when working in a space away from the entrance. Conclusions: Various applications of smart safety technology have been confirmed based on the measured data, and this is expected to be useful for environmental characteristic analysis and safety management when applied to a confined space composed with various conditions in the future.

Objectives: 21 sepiolite substances produced in China were investigated for the presence of asbestos in their materials. Materials and methods: In order to identify asbestos in sepiolite substances, test materials were analyzed using a transmission electron microscope equipped with energy dispersive X-ray spectrometer (TEM-EDS) for confirming their shape and components (atomic %). Results: Five of 21 sepiolte substances were asbestos-containing materials. Two chrysotile containing sepiolite proved to be asbestoscontaining materials, as did two chrysotile mixed with tremolite containing sepiolite. 16 sepiolite substances did not contain asbestos materials. Conclusions: When importing sepiolite substances, they must be analyzed to determine if there is asbestos in their materials.

The total number of confined space accident cases from 1999 to 2007 in Korea were 220, causing 353 injuries and 212 casualties. Out of 220 cases, 44(20.0%) occurred in sewage treatment facilities and 40(18.2%) occurred in both manholes and containers. When the main causes of confined space accidents were classified, oxygen deficiency accounted for 69 cases(31.4%), carbon monoxide, 48(21.8%), hydrogen sulfide, 40(18.2%), and organic solvent, 32(14.5%). Improvement of occupational accident statistics is necessary in order to report accurate and precise data for confined space accidents. The structure of confined space must be considered when selecting gas to be measured.

The Process Safety Management (PSM) by the Law of Industry, Safety and Health has been performed for preventing major accidents of chemical plants since 1996. In terms of preventing chemical accidents more precisely, it is essential to develop a tool for quantitative risk assessment. For this, KOSHA (Korea Occupational Safety and Health Agency) developed an Integrated Risk Management System (IRMS). The system is designed to assimilate data on chemical plant hazards from external database, to integrate these data with location information(topographic and demographic), and to make them user-friendly accessible. The system consists of several main functions: display of five major Korean petrochemical complex layout display of equipment layout with its information utilizing the external database, zonation of the hazard effected area with consequence analyses, the most probable accident scenario generation, accident/incident database and calculation of frequency of accident using equipment reliability database, etc. The highlight of IRMS is to provide the risk contours using GIS(Geographical Information System) technology. IRMS is intended to manage hazardous installation more systematically and effectively, to reduce the number of accident remarkably, further minimizing production loss in the plant. The system is now under application to about 500 PSM sites as well as and emergency authorities in Korea by KOSHA (Korea Occupational Safety and Health Agency)

The occupations involved in food animal production have long been recognized to carry significant health risks for workers, with special attention to injuries. However, risk of pathogen exposure in these occupations has been less extensively considered. Pathogens are a food safety issue and are known to be present throughout the food animal production chain. Workers employed at farms and slaughterhouses are at risk of pathogen exposure and bacterial infections. The industrialization of animal farming and the use of antimicrobials in animal feed to promote growth have increased the development of antimicrobial resistance. The changed nature of these pathogens exposes workers in this industry to new strains, thus modifying the risks and health consequences for these workers. These risks are not yet recognized by any work-related health and safety agency in the world.
