  • This study analyzed the characteristics of chemical accidents, including the accidents occurring each year according to status, type of accident, accident cause for chemical substance transporting accidents. The major aim of this study was to provide information on the chemical accidents that occurred involving chemical substance transporting accidents from 2013 to July - 2016. The total incidence of chemical transporting accidents was 77 cases; 74 cases occurred by the spill & leakage type. The main cause of the accidents analyzed was traffic accidents (41 cases). Forty-six accidents were related to hazardous chemical substances. Among the 46 hazardous chemical substances involved in transporting chemical accidents, 46% of the accident substances were hydrogen chloride. For the prevention and response to accidents occurring during the transportation of chemicals, it is necessary to complement the precautions for chemical accidents caused by transportation accidents and chemical spills and leaks of chemicals. In addition, when the chemical transport of an accident occurs, it is necessary to apply a chemical transport safety system for chemical transfer.

  • Objectives: We investigated the status of accidents and deaths caused by chemical leakage and skin contact in Korea. The purpose of this study was to produce and provide technical reference data for the efficient management of accidents and the rational management of accidental chemicals. Methods: Accidents and deaths caused by chemical leakage and skin contact in industry were investigated. Based on 68 accident reports related to chemical leakage and skin contact, the causes of accidental deaths were analyzed. In addition, we investigated the chemical substances and articles that caused these accidents and deaths. Based on the results of the investigation, the causes of accidents caused by chemical leakage and skin contact were identified and practical management measures for the chemicals were suggested. Results and Conclusions: In 2018, 372 people suffered from chemical leaks and skin contact, up by 123 (about 49.4%) from the previous year. The number of accident deaths was 14, an increase of five (about 55.6%) from the previous year. In the last three years (2016-2018), 91 chemical substances and article groups were involved in accidents caused by chemical leakage and skin contact. There were 16 chemical substance and article groups involved in accidental deaths. There were ten cases of accidents involving two or more casualties due to chemical leakage and skin contact, and 23 deaths occurred. Most of these accidental deaths were caused by subcontractor workers outsourcing risks. Therefore, there is an apparent need to strengthen the responsibility for safety and health among subcontractors.

  • The Ministry of Employment and Labor implemented the process safety management(PSM) system from 1996 to prevent major industrial accidents caused by chemical substances, but the number of accidents did not drastically decrease. Even in workplaces with excellent PSM ratings, large-scale chemical accidents still occur due to non-compliance with safety work procedures and insufficient safety measures during maintenance and other work. Accordingly, the chemical accident risk warning system was introduced in 2014 to supplement the PSM system and prevent accidents that may occur during regular or unexpected maintenance and repair work. In the meantime, changes in the safety management system have been checked since the introduction of the chemical accident risk warning system at chemical handling workplaces, and based on the results, a plan for upgrading this system has been proposed. The effect of the CARW system was found to directly prevent accidents through wired and on-site consulting and post-management at the workplace and indirectly contribute to the establishment of a safety and health management system at the workplace, such as improving safety culture awareness.

  • During the transportation of chemicals, quantitative risk assessment for chemical leakage accidents caused by traffic accidents was carried out and the appropriateness of chemical transportation route was evaluated. The quantitative risk assessment method applied to the chemical leakage accidents that may occur in the chemical handling equipments installed in the workplace was presented and applied to the chemical transportation. By analyzing the number of traffic accidents in transportation vehicles, the probability of chemical leakage accidents during chemical transportation was predicted and applied to the quantitative risk assessment of chlorine gas leakage accidents that may occur when transporting liquified chlorine bombe using vehicles. As a result, the most appropriate route of transporting the liquefied chlorine bombe was suggested on the basis of risk.

  • Chemical accidents occur by a variety of causes and aspects. Accident preparedness substances (APS) are defined by toxic chemicals highly likely to cause accidents due to their high acute toxicity, explosiveness or likely to cause severe damage where a chemical accident occurs among the chemicals. APS is designated and announced by Presidential Decree. However, chemical accidents occurred for recent 7 years were arisen mainly from non-accident preparedness substances, and only 24 species were included as chemical accident trigger among total 69 APS. In addition, APS were designated in 2014 and the list has not been updated since then although it needs to be amended in several aspects. Accordingly, this study analyzes the necessity of modification of APS management, and presents improved plans.
