As the scale of explosions diversifies along with the expansion of gas handling and storage facilities, studies on explosion-proof facilities in preparation for accidents is being actively conducted. The gastight door blocks the expansion pressure caused by blast waves or internal fires, and at the same time protects the personnel and equipment inside. For gastight doors, the regulations related to explosion-proof design are not clearly presented, and studies on the explosion pressure resistance performance evaluation of the facility are insufficient. In this study, the gastight door was modeled in a 3D shape with reference to the regulation ASTM regarding the gastight door standard. Afterwards, evaluation for blast-resistant performance of gastight door using Numerical simulation was evaluated by using ANSYS Explicit Dynamics to compare the deformation.

Objectives: The successful implementation of the Port Safety Special Act is a very important matter. Now that one year has passed since its introduction, this study aims to review the achievements so far and identify future tasks. Methods: The provisions of the Special Act on Port Safety were analyzed and the latest literature related to port safety management was reviewed. In addition, an in-depth interview was conducted with a business owner. Results: The achievements over the past year are as follows. As business operators took greater responsibility for safety management, blind spots in safety were resolved to an extent. Specialized training for the port unloading industry was provided, and a safety management system was established for unloading docks. In addition, the Ministry of Oceans and Fisheries was able to intervene in the prevention of safety accidents at ports through the deployment of port safety inspectors. In 2022, the port industry accident frequency and death rate declined compared to the previous year. Conclusions: The "Port Safety Special Act" has become relatively well established in the port industry over the past year. However, since the Serious Disaster Punishment Act was implemented in January of the same year, there is a limit on determining what is necessarily the effect of the Special Act. Future tasks include unifying contracts centered on cargo handling companies, supporting safety management costs, increasing the number of port safety inspectors, producing reliable port disaster statistics, and cooperating between the Ministry of Oceans and Fisheries and the Ministry of Employment and Labor.

The main purpose of this study was to find out the actual status of safety and heal th education activities in the manufacturing industries through survey of 136 plants in Seoul City and Gyunggi- Province Area which employ nurses being charged in the safety and health care services to the employees. A questionaire was mailed to the employees on the Mar. 2, 1987. Total 634 responds from 87 industries were collected by Apr. 20, 1987. Among the total, 618 responds from 80 industries were included in the analysis. The major findings obtainded from this study are summarized as follows; 1. Safety and health education activities in each industry: 1) The $67.6\%$ of safety directors surveyed were performing the education to the employees. And in case of medical directors, it was $18.8\%$ of them. 2) Periodically, annual safety' and health education programs were being drawn up in the $65.0\%$ of the industries (52 companies). And the $60.6\%$ of the planners were safety directors of safety staffs in charge. 3) It was only $27.5\%$ of the companies surveyed in which the safety and health education were performed more than an hour every month. In the $22.5\%$ of the companies, neither safety programs nor health education activities were performed. 4) In the $47.5\%$ of them, safety and health educations were performed in cooperation with related agencies such as health center. 2. The rate of employees participated in safety and health educations; 1) The received rates by subjects of the educations when labors were newly employed to their companies were as follows; education regarding danger and profer handling method of machinery and appliances: $64.2\%$, education regarding noxiousness and handling method of raw materials: $42.2\%$, etc. 2) The $63.6\%$ of the labors received educations on safety and health when they changed their work places. 3) The $74.8\%$ of the labors received specific safety and health educations. 4) The general safety and health educations were received by the $47.2\%$ of management and clerical personnel and $50.0\%$ of labors pre and post physical examination. 3. The main reasons of inactive performance of the educations were as follows; lack of knowledge and inexperience of the occupational safety and health staffs, lack of cooperations between themselves and low need of workers for safety and health education, etc. 4. The preferable subjects of educations for workers; (1) pre and post education of physical examination, (2) education regarding the prevention of accidents. (3) general health care, sex education and family planning, etc. As a result of this study, we can conclude that the safety and health education work in industries as the subject of this study is on the incipient stage. Appropriate measures are to be taken for the activation of safety and health education work such as; continuous public relations, financial and technical supports of the government, training of professional/occupational safety and health staffs, efforts of workers to receive the education and collaborations of the employers.

As the collection and use of personal information increases, the accidents that abuse and leak personal information are continuously increasing. The nation has established new laws and strengthened related laws for the prevention of the mass leakage of personal information and the secondary damage due to the leaked personal information. The nation also established the guidelines that need to be implemented by the institutions handling personal information for the safety of the personal information. For the efficient implementation of guidelines under the limited time and resources, it is necessary to establish the priorities between guidelines. This paper compares the relative importance of the guidelines by AHP (Analytic Hierarchy Process) technique. We performed the analysis on two expert groups, the group of consultants working in information security consulting company and the group of information security staffs handling personal information directly in the company. We compared the differences between groups and recommended the relative importances of the guidelines.

Purpose: The purpose of this study is suggested to improve upon current existing methods of ammonia chemical accident prevention and damage reduction. Method: Ammonia is one of the most common toxic substances that causes frequent chemical accidents. And it was selected as leakage materials according to statistics on chemical accident. Based on actual cases of chemical accidents, CARIS modeling was used to compare the damage impact range of Ammonia and HCl and Cl. Also, find out problems with the current systems. Result: As a result of find out the range of accident influence that spreads to the surroundings when an ammonia chemical accident, it was longer than the range of influence of hydrochloric acid and shorter than that of chlorine. In addition, it was found that when chemical accident by ammonia, hydrochloric acid, or chlorine, there are apartments and schools, which can have an effect. Conclusion: It is decided that it is necessary to determine whether or not chemical accident prevention management plans and statistical investigations are submitted for workplaces dealing with ammonia, and detailed guidelines and reviews are necessary. In addition, it is judged that it is necessary to establish a DB for ammonia handling plants, and it is considered that information sharing and joint inspection among related organizations should be pursued.

Objectives: Personal protective equipment (PPE) is an essential means for protecting workers against hazardous agents or risks that threaten their safety and health. Governmental organizations related to safety and health in the workplace regulate the PPE rules to protect workers and to minimize damage from hazardous agents. This study discussed current PPE rules overseen by the Korea Ministry of Environment and explores future perspectives on the matter. Methods: This study was based on a review of PPE regulations with which every stakeholder should comply in the workplace. Both South Korean regulations enforced by the Ministry of Employment and Labor and the Ministry of Environment and cases from other countries were reviewed. Results: Regulations related to the PPE required for handling chemical substances in the workplace are enforced by the Occupational Safety and Health Act, Enforcement Decree, Enforcement Rules, and Notification of Protective Equipment Certification under the Ministry of Employment and Labor. The Ministry of Environment also regulates the PPE standards for 97 substances requiring preparation for accidents and adjustment of work conditions, but a recent amendment (partially amended on September 30, 2022) loosened some unreasonable or excessive provisions. It requires workers simply to carry or otherwise keep PPE handy instead of wearing it for some tasks in which hazardous chemicals are not handled directly. Conclusions: It is important to regularly review provisions that need to be improved or supplemented to help all stakeholders. Considerations should be also made to build a reasonable regulatory system that can induce more mature safety management in each workplace.

Objectives: The new Chemical Control Act from the Korean Ministry of Environment (2014-259) simply states only in basic phrases that every worker handling the listed chemicals should wear personal protective equipment (PPE) and does not consider the different hazard characteristics of particular chemicals or work types. The purpose of this study was to produce an exposure risk matrix and assign PPE to the categories of this matrix, which would be useful for revising the act to suggest PPE to suit work types or situations. Methods: An exposure risk matrix was made using hazard ranks of chemicals and workplace exposure risks in the previous study. For the 20 categories of exposure risk matrix PPE, levels A, B, C, D as classified by OSHA/EPA were assigned. After 69 hazardous chemicals were divided into 11 groups according to their physiochemical characteristics, respirators, chemical protective clothing (CPC), gloves and footwear were suggested on the basis of the assigned PPE levels. Results: PPE table sheets for the 11 groups were made on the basis of work types or situations. Full facepiece or half-mask for level C was recommended in accordance with the exposure risk matrix. Level A was, in particular, recommended for loading or unloading work. Level A PPE should be worn in an emergency involving hydrogen fluoride because of the number of recent related accidents in Korea. Conclusion: PPE assignment according to the exposure risk matrix made by chemical hazards and work type or situation was suggested for the first time. Each type of PPE was recommended for the grouped chemicals. The research will be usefully used for the revision of the Chemical Control Act in Korea.

Objectives: Despite the positive effects of Off-site risk assessment (ORA) system such as prevention of chemical accidents, some problems have been constantly raised. The purpose of this study is to analyze the problems that have occurred through the implementation of the ORA system for the past three years and to suggest reasonable directions for improvement in the future. Methods: In order to identify the problems with the methodology and procedure of ORA system, we analyzed statutes, administrative rules and documents related to the ORA system. A survey of ORA reviewers in National Institute of Chemical Safety was conducted to investigate the weight of determinants considered when judging the level of total risk in ORA. Results: In this study, we found out the uncertainty of the estimation of the number of people in the impact range in the procedure of the risk assessment of individual handling facilities, the lack of quantitative risk analysis methods for environmental receptors, and the ambiguity of the criteria for the total risk. In addition to suggesting solutions to the problems mentioned above, we also, suggested a decision tree for total risk in ORA. Conclusion: We anticipate that the solutions including the systematic decision tree for total risk suggested will contribute to the smooth operation of the ORA system.
