Revising the Occupational Safety and Health Act led to enacting and revising related laws and systems, such as placing fire observers in hot workplaces. However, the operating standards in such cases are still ambiguous. Although fire accidents occur through multiple and multi-step factors, the hazards of fire accidents have been identified in this study as individual rather than interrelated factors. The aim has been to identify multiple factors of accidents, outlining fire and explosion accidents that recently occurred in the domestic manufacturing industry. First, major keywords were extracted through text mining. Then representative accident types were derived by combining the main keywords through the co-word network analysis to identify the hazards and their relationships. The representative fire accidents were identified as six types, and their major hazards were then addressed for improving safety measures using the identification of hazards in the "Risk Assessment" tool. It is found that various safety measures, such as professional fire observers' training and clear placement standards, are needed. This study will provide useful basic data for revising practical laws and guidelines for fire accident prevention, system supplementation, safety policy establishment, and future related research.

Objectives: South Korea's occupational safety and health legislation appears on the surface to have stronger regulations than any other country, but it is criticized for having many problems when viewed from the perspective of the effectiveness and universality of these regulations. Therefore, it is necessary to consider the validity of the regulatory content and the methods for contract work in South Korea. Methods: The main issues in contract work are compared and analyzed in terms of the occupational safety and health laws systems in South Korea and other developed countries. Based on this, problems related to contract regulation are derived from the perspective of legal policy studies. In addition, effective improvement measures for the derived problems will be proposed. Results: Other developed countries impose obligations suitable for the status and role of persons who entrust work in consideration of the fact that they do not directly manage risks and in terms of the effectiveness of industrial accident prevention. These countries generally impose obligations such as management of facilities and machinery, cooperation and coordination with subcontractors, cooperation and coordination obligations between subcontractors, and guidance obligations on a person who entrusts a work. Conclusions: It is difficult to achieve effectiveness in preventing accidents with based on unreasonable regulations that do not conform to safety principles or legal theory. Regulations on contract work need to be converted to rational cogent regulations based on science and rationality, not ideology and emotion. To this end, the legal system for contract work must have international universality.

Objectives: After the MSDS submission and non-disclosure review system was introduced in January 2021, there were compliance difficulties in the field. Accordingly, for the establishment of the MSDS system, the government intends to investigate what has been improved and what urgently needs to be improved in the future, and to suggest detailed improvement plans. Methods: The background and problems of urgent difficulties in the field handling chemicals were investigated, and realistic improvement plans were derived through review of other laws related to the MSDS system and overseas cases. Results: In order to guarantee the safety of the public while at the same time promoting corporate R&D, it is necessary to alleviate the non-disclosure screening system for chemical substances for R&D, and to improve the irrationality of failing to implement the non-disclosure screening system due to information on unclassified substances being circulated. For this reason, it seems necessary to ease the requirement to submit all ingredients. In addition, it is necessary to strengthen punishment to raise awareness so that health problems do not occur due to the harmfulness and danger of hidden substances among workers who handle chemical substances and downstream users due to false descriptions in MSDS. Conclusions: All members of our society, including chemical manufacturers/importers and handling companies, academia, civil society, and the government, each subject of chemicals, should take an interest in the entire process from production to disposal of chemicals and work together to prevent harm to the public.

본 연구에서는 정부정책이 효과가 있었는지 파악하기 위하여 과거 10년간의 산업재해 데이터를 살펴보았다. 이들 데이터로부터 중요한 두 개 또는 세 개의 변수간의 관계를 EDA 방법으로 살펴보았다. 근로자수(사업장규모)와 생존확률 간의 관계를 살펴본 결과 근로자수가 많을수록 시간이 지남에 따라 생존확률이 더욱 더 떨어짐(산업재해가 더 많이 일어남)을 알 수 있다. Cox의 비례위험모형을 적용해본 결과 사업장에서 발생한 총산업재해수가 많을수록 해당 사업장에서 산업재해가 발생할 위험성(hazard)이 높아지고, 근로자수가 적을수록 산업재해가 발생할 위험성이 높으며, 업종별로는 농업, 어업 및 임업이 건설업에 비해 산업재해를 당할 위험성이 더 크다. 공단, 민간 및 고용노동부의 역할은 고용노동부만 효과가 있고, 나머지 두 조직은 효과가 없는 것으로 나온다. recurrent event data를 Cox의 비례위험모델로 분석해본 결과 비슷한 결과가 나온다.

Korea government has established and enforced countermeasures about the various policy of industrial accident prevention. Recent chemical accidents included hazardous materials. Exposure to these chemicals can cause serious environmental poisoning and various health problems. The key factor causing these major accidents may be associated with the mistake in workers' safety behaviors. Some researchers noted workers' safety behaviors may be related to workers' safety climate. In this research, a survey was conducted to explore workers' safety behaviors and safety climate in a large petrochemical company in Korea. The company processes major petrochemical materials and any spills can be hazardous and cause chemical disasters. In this study, we explored one petrochemical company to investigate three hypotheses. 593 workers were surveyed for this study. We checked association between workers' safety behavior and safety climate. The survey result shows the people who have safety climate do safe behavior.
