Abstract

The size of the OLED material market is expected to grow from $1.1 billion in 2019 to $2.3 billion in 2023, with an average annual sustainable growth of more than 19%. Among the facilities mainly used by OLED material manufacturers, accidents such as fire, explosion, and leakage frequently occur when using filtration equipment, so it is necessary to improve the risk when using filtration equipment. In this study, it was divided into four main processes, namely, assembly and disassembly process, filtration process, wet cake recovery process, and washing process in order to derive the risks associated with the use of filtration equipment. Hazard factors were derived by conducting accident case investigations, preliminary interviews, and surveys. For the analysis of questionnaire results, statistical analysis such as frequency analysis and Pearson chi-square test analysis was performed using SPSS 21, and risk improvement measures were suggested using the analyzed results. It is expected that this study will serve as a basis for dealing with safety and risk factors that may occur as the size of the OLED market expands.

OLED 소재 시장의 규모는 2019년 11억 달러에서 2023년 23억 달러로 연평균 19% 이상 지속적인 성장이 예상된다. OLED 소재 제조사에서 주로 사용하고 있는 설비 중 여과 설비는 사용 시 화재, 폭발, 누출 등의 사고들이 빈번히 발생하고 있어, 이에 대한 여과 설비사용 시의 위험성 개선이 요구된다. 해당 연구에서는 여과 설비사용에 따른 위험성을 도출하기 위해 주요공정 즉 조립 및 분해공정, 여과공정, wet cake 회수공정, 세척공정의 4가지로 나누어 사고사례조사, 사전인터뷰, 설문조사 등을 실시하여 유해 위험 요인을 도출하였다. 설문 결과의 분석은 SPSS 21을 이용하여 빈도분석, Pearson 카이제곱 검정 분석을 수행하여 분석된 결과를 활용하여 위험성 개선 방안들을 제시하였다. 이 연구가 OLED 시장 규모가 확대됨에 따라 발생할 수 있는 안전 및 위험 요인들을 다루는데 기초자료가 될 것으로 기대한다.
