Abstract：
The management of workplace chemicals shifted from a regulatory-based to a self-managed approach as of April 2023. To assess readiness, concerns, and necessary support for this change, a free-response questionnaire survey was conducted for the participants of the \"Promoting self-management of chemicals in enterprises\" seminar held by the Department of Occupational Health, Graduate School of Medicine, University of Occupational and Environmental Health, Japan, in January-February 2023. Text-mining using KH Coder (Ver.3) was conducted to investigate relationships between words that appeared in sentences using a co-occurrence network and hierarchical cluster analysis. From the questionnaire\'s description text, combinations of the terms \"information\" and \"collection,\" \"small and medium-sized\" and \"enterprise,\" and \"chemical\" and \"substance\" were extracted. Results suggest a need for \"information gathering\" and \"support for small and medium-sized enterprises.\"
