This study aims to derive implications through theoretical exploration of hazardous goods storage facilities and case analysis of fires occurring on the hazardous goods, and based on which, to suggest improvement measures for effective safety management of hazardous goods storage facilities to prevent fires occurring in large-scale hazardous goods storage facilities and minimize damage through a survey of employees engaged in the business of hazardous goods and firefighters.
As implications by analyzing accident cases of hazardous goods manufacturing plants, etc., First, large-scale hazardous goods indoor storage facilities exceeding 2,000 times the designated quantity shall not apply reduction conditions for vacant land under possession. Second, glass-wool sandwich panels should not be recognized as fire-resistant structures. Third, indoor storage facilities should be equipped with automatic fire-fighting facilities. Fourth, the scale and legislating oil-water separators that allow mixed storage of hazardous and non-hazardous substances are needed to be expanded and legislated.
This study conducted interviews and a survey with employees working in the hazardous goods handling companies and firefighters to empirically analyze measures to improve the safety management of hazardous goodsl storage facilities. Based on literature research and interview surveys, the main variables for improving the safety management of hazardous goods storage facilities were selected, such as facility standards, storage and handling standards, transportation and transport standards, institutional standards, and fire-fighting equipment standards. In the case of sample selection, a survey was conducted by assigning employees working in hazardous goods handling companies and firefighters, and 272 collected questionnaires were analyzed.
This study conducted frequency analysis, multiple regression analysis using the collected data, and through which, the perception of significant variables and their differences were analyzed, and the influence of each independent variable on the dependent variable was identified, and the hypothesis presented in this study was verified.
When organizing the response distribution of each variable, it was found that the subjects showed very positive perception on the improvement of safety management of hazardous goods storage facilities, which is the dependent variable of this study. Looking at the average of the 5-point Likert scale, the level of awareness was high at 3.95, indicating that the survey subjects agreed that the safety management of hazardous goods storage facilities should be improved.
In the response distribution of the independent variables, first, the subjects showed a positive perception of vacant land under possession (3.25) on the hazardous goods facility standards and showed a positive perception on the oil-water separator (3.94) and indoor underground storage (3.42). Second, in the case of hazardous goods storage and handling standards, the subjects showed a positive perception on the compartment installation (4.00), a generally positive perception on the underground storage (3.13), and a very positive perception on the fire and explosion prevention (4.20). Third, in the case of hazardous material transportation and transport standards, the subjects showed a very positive perception on the integrator training (4.10), transport vehicle marking (3.94), and fixation and tying (4.18). Fourth, in terms of institutional standards, the subjects showed a positive perception on their fire brigade (3.72) and a very positive perception on the hazardous material facilities (3.97) and fire-resistant structures (4.10). Fifth, in terms of fire-fighting equipment standards, the subjects showed a very positive perception on the automatic fire-fighting equipment (4.10) and appropriate fire-fighting equipment (4.17) and a positive perception on the indoor fire extinguisher water sources (3.70).
As a result of conducting multiple regression analysis to verify the influence of each independent variable on the safety management of hazardous goods storage facilities, storage and handling standards, transportation and transport standards, institutional standards, and fire extinguishing facility standards were found to be influential variables on the safety management of hazardous goods storage facilities. However, facility standards did not have a statistically significant effect. Regarding the relative weight of each variable, storage and handling standards were the most influential variable, followed by transportation and transport standards, institutional standards, and fire extinguishing facility standards.
This study is significant in that it suggests the direction in which to focus on safety management policies for hazardous goods storage facilities by showing that storage and handling standards, transportation and transport standards, institutional standards, and fire extinguishing facility standards play an important role in improving the safety management of hazardous material storage facilities. In this respect, this study is differentiated from other studies in that it comprehensively considers the standards for storage and handling of hazardous goods, transportation and transport standards, institutional standards, and fire-fighting equipment standards for hazardous goods storage facilities, and presents factors influencing the safety management of hazardous goods storage facilities.
