Factors Influencing Compliance with COVID-19 Disinfection Safety Guidelines among Disinfection Workers in South Korea

The Coronavirus Disease 2019 (COVID-19) pandemic has increased the global demand for disinfection services. Disinfection work involves specialized expertise in the use of chemicals and equipment. However, many studies have not illuminated the essential knowledge and practices of disinfection workers. This study aims to investigate factors influencing disinfection practices to enhance the quality and safety of infection-control measures. A cross-sectional descriptive study among 215 disinfection workers in South Korea was undertaken. The survey questionnaire was designed to collect information on demographic characteristics, disinfection methods, knowledge of COVID-19 disinfectants and their application, and the use of personal protective equipment. Data were analyzed using SPSS 26. Participants who received COVID-19 disinfection training had more knowledge regarding disinfectant products, demonstrated greater adherence to disinfection guidelines, and used more disposable PPE items. The multiple linear regression analysis revealed that being female, completing prior training on COVID-19 disinfection, obtaining disinfectant information through official education, and possessing a subjective awareness of COVID-19 disinfectants and disinfectant knowledge were associated with increased compliance with guidelines for disinfection. This study revealed a gap between perceived compliance and actual knowledge between groups. These findings highlight the importance of retraining disinfection workers, enhancing their qualifications, and promoting responsible disinfection practices.
